A Guide To Filing A Design Patent Application
Definition of a Design
Adesign consists of the visual ornamental
characteristics embodied in, or applied to, an
article of manufacture. Since a design is
manifested in appearance, the subject matter of a
design patent application may relate to the
configuration or shape of an article, to the surface
ornamentation applied to an article, or to the
combination
of
configuration
and
surface
ornamentation. A design for surface ornamentation is
inseparable from the article to which it is applied and
cannot exist alone. It must be a definite pattern of
surface ornamentation, applied to an article of
manufacture.
In discharging its patent-related duties, the United
States Patent and Trademark Office (USPTO or
Office) examines applications and grants patents on
inventions when applicants are entitled to them. The
patent law provides for the granting of design patents
to any person who has invented any new, original and
ornamental design for an article of manufacture. A
design patent protects only the appearance of the
article and not structural or utilitarian features. The
principal statutes (United States Code) governing
design patents are:
35 U.S.C. 171
35 U.S.C 172
35 U.S.C. 173
35 U.S.C. 102
35 U.S.C. 103
35 U.S.C. 112
35 U.S.C. 132
The rules (Code of Federal Regulations) pertaining
to the drawing disclosure of a design patent
application are:
37 CFR § 1.84
37 CFR § 1.152
37 CFR § 1.121
The following additional rules have been referred to
in this guide:
37 CFR § 1.3
37 CFR § 1.63
37 CFR § 1.76
37 CFR § 1.153
37 CFR § 1.154
37 CFR § 1.155
A copy of these laws and rules is included at the end
of this guide.
The practice and procedures relating to design
applications are set forth in chapter 1500 of the
Manual of Patent Examining Procedure (MPEP).
Inquiries relating to the sale of the MPEP should be
directed to the Superintendent of Documents, United
States Government Printing Office, Washington,
D.C. 20402. Telephone: 202.512.1800.
Types of Designs and
Modified Forms
An ornamental design may be embodied in an entire
article or only a portion of an article, or may be
ornamentation applied to an article. If a design is
directed to just surface ornamentation, it must be
shown applied to an article in the drawings, and the
article must be shown in broken lines, as it forms no
part of the claimed design.
A design patent application may only have a single
claim (37 CFR § 1.153). Designs that are
independent and distinct must be filed in separate
applications since they cannot be supported by a
single claim. Designs are independent if there is no
apparent relationship between two or more articles.
For example, a pair of eyeglasses and a door handle
are independent articles and must be claimed in
separate applications. Designs are considered distinct
if they have different shapes and appearances even
1

n Patent and Trademark Office
n Washington, DC 20231
A Guide To Filing A Design Patent Application
United States Patent and Trademark Office
2
though they are related articles. For example, two
vases having different surface ornamentation
creating distinct appearances must be claimed in
separate applications. However, modified forms, or
embodiments of a single design concept may be filed
in one application. For example, vases with only
minimal
configuration differences may be
considered a single design concept and both
embodiments may be included in a single
application. An example of modified forms appears
at the bottom of Page 16.
The Difference Between Design
and Utility Patents
In general terms, a “utility patent” protects the way
an article is used and works (35 U.S.C. 101), while a
"design patent" protects the way an article looks (35
U.S.C. 171). Both design and utility patents may be
obtained on an article if invention resides both in its
utility and ornamental appearance. While utility and
design patents afford legally separate protection, the
utility and ornamentality of an article are not easily
separable. Articles of manufacture may possess both
functional and ornamental characteristics.
Improper Subject Matter for
Design Patents
A design for an article of manufacture that is
dictated primarily by the function of the article lacks
ornamentality and is not proper statutory subject
matter under 35 U.S.C. 171. Specifically, if at the
time the design was created, there was no unique or
distinctive shape or appearance to the article not
dictated by the function that it performs, the design
lacks ornamentality and is not proper subject matter.
In addition, 35 U.S.C. 171 requires that a design to
be patentable must be “original.” Clearly a design
that simulates a well-known or naturally occurring
object or person is not original as required by the
statute. Furthermore, subject matter that could be
considered offensive to any race, religion, sex,
ethnic group, or nationality is not proper subject
matter for a design patent application (35 U.S.C. 171
and 37 CFR § 1.3).
Invention Development
Organizations
Invention Development Organizations (IDO) are
private and public consulting and marketing
businesses that exist to help inventors bring their
inventions to market, or to otherwise profit from their
ideas. While many of these organizations are
legitimate, some are not. Be wary of any IDO that is
willing to promote your invention or product without
making a detailed inquiry into the merits of your idea
and giving you a full range of options which may or
may not include the pursuit of patent protection.
Some IDOs will automatically recommend that you
pursue patent protection for your idea with little
regard for the value of any patent that may ultimately
issue. For example, an IDO may recommend that you
add ornamentation to your product in order to render
it eligible for a design patent, but not really explain
to you the purpose or effect of such a change.
Because design patents protect only the appearance
of an article of manufacture, it is possible that
minimal differences between similar designs can
render each patentable. Therefore, even though you
may ultimately receive a design patent for your
product, the protection afforded by such a patent may
be somewhat limited. Finally, you should also be
aware of the broad distinction between utility and
design patents, and realize that a design patent may
not give you the protection desired.
Elements of a Design
Patent Application
The elements of a design patent application should
include the following:
(1) Preamble, stating name of the applicant, title of
the design, and a brief description of the nature
and intended use of the article in which the
design is embodied;
(2) Description of the figure(s) of the drawing;
(3) Feature description (optional);
(4) A single claim;
(5) Drawings or photographs;
(6) Executed oath or declaration.
United States Patent and Trademark Office
A Guide To Filing A Design Patent Application
In addition, the filing fee set forth in 37 CFR
§1.16(f) is also required. If applicant is a small
entity, (an independent inventor, a small business
concern, or a non-profit organization), the filing fee
is reduced by half.
The Preamble
The Preamble, if included, should state the name of
the applicant, the title of the design, and a brief
description of the nature and intended use of the
article in which the design is embodied. All
information contained in the preamble will be printed
on the patent, should the claimed design be deemed
patentable.
The Title
The Title of the design must identify the article in
which the design is embodied by the name generally
known and used by the public. Marketing
designations are improper as titles and should not be
used. A title descriptive of the actual article aids the
examiner in developing a complete field of search of
the prior art. It further aids in the proper assignment
of new applications to the appropriate class, subclass,
and patent examiner, as well as the proper
classification of the patent upon allowance of the
application. It also helps the public in understanding
the nature and use of the article embodying the
design after the patent has been published. Thus,
applicants are encouraged to provide a specific and
descriptive title.
The Figure Descriptions
The Figure Descriptions indicate what each view of
the drawings represents, i.e., front elevation, top
plan, perspective view, etc.
Any description of the design in the specification,
other than a brief description of the drawing, is
generally not necessary since, as a general rule, the
drawing is the design's best description. However,
while not required, a special description is not
prohibited.
In addition to the figure descriptions, the following
types of statements are permissible in the
specification:
1. A description of the appearance of portions of the
claimed design which are not illustrated in the
drawing disclosure (i.e., “the right side elevational
view is a mirror image of the left side”).
2.Description disclaiming portions of the article not
shown, that form no part of the claimed design.
3.Statement indicating that any broken line
illustration of environmental structure in the
drawing is not part of the design sought to
be patented.
4.Description denoting the nature and environmental
use of the claimed design, if not included in
the preamble.
A Single Claim
A design patent application may only include a single
claim. The claim defines the design which applicant
wishes to patent, in terms of the article in which it is
embodied or applied. The claim must be in formal
terms to “The ornamental design for (the article
which embodies the design or to which it is applied)
as shown.” The description of the article in the claim
should be consistent in terminology with the title of
the invention.
When there is a properly included special description
of the design in the specification, or a proper
showing of modified forms of the design, or other
descriptive matter has been included in the
specification, the words “and described” should be
added to the claim following the term “shown.” The
claim should then read “The ornamental design for
(the article which embodies the design or to which it
is applied) as shown and described.”
Drawings or Black and
White Photographs
The drawing disclosure is the most important
element of the application. Every design patent
application must include either a drawing or a black
and white photograph of the claimed design. As the
3
A Guide To Filing A Design Patent Application
United States Patent and Trademark Office
4
drawing or photograph constitutes the entire visual
disclosure of the claim, it is of utmost importance
that the drawing or photograph be clear and
complete, that nothing regarding the design sought to
be patented is left to conjecture. The design drawing
or photograph must comply with the disclosure
requirements of 35 U.S.C. 112, first paragraph. To
meet the requirements of 35 U.S.C. 112, the
drawings or photographs must include a sufficient
number of views to constitute a complete disclosure
of the appearance of the design claimed.
Drawings are normally required to be in black ink on
white paper. Black and white photographs, in lieu of
drawings, are permitted subject to the requirements
of 37 CFR §1.84(b)(1) and §1.152. Applicant should
refer to these rules, included at the end of this guide.
These rules set forth in detail the requirements for
proper drawings in a design patent application.
Black and white photographs submitted on double
weight photographic paper must have the drawing
figure number entered on the face of the photograph.
Photographs mounted on Bristol board may have the
figure number shown in black ink on the Bristol
board, proximate the corresponding photograph.
Black and white photographs and ink drawings must
not be combined in a formal submission of the visual
disclosure of the claimed design in one application.
The introduction of both photographs and ink
drawings in a design application would result in a
high probability of
inconsistencies between
corresponding elements on the ink drawings as
compared with the photographs. Photographs
submitted in lieu of ink drawings must not disclose
environmental structure but must be limited to the
claimed design itself.
Color Drawings or
Color Photographs
The Office will accept color drawings or
photographs
in
design patent
applications
only after the granting of a petition filed under
37 CFR §1.84(a)(2), explaining why the color
drawings or photographs are necessary. Any
such petition must include the fee set forth in
37 CFR § 1.17(h), three sets of color drawings or
photographs, a black and white photocopy that
accurately depicts the subject matter shown in the
color drawings or photographs, and the specification
must contain the following language before the
description of the drawings:
The file of this patent contains a least one drawing
executed in color. Copies of this patent with color
drawings will be provided by the United States
Patent and Trademark Office upon request and
payment of the necessary fee.
If color photographs are submitted as informal
drawings and the applicant does not consider the
color to be part of the claimed design, a disclaimer
should be added to the specification as follows: “The
color shown on the claimed design forms no part
thereof.” Color will be considered an integral part of
the disclosed and claimed design in the absence of a
disclaimer filed with the original application. A
disclaimer may only be used when filing color
photographs as informal drawings, as 37 CFR §1.152
requires that the disclosure in formal photographs be
limited to the design for the article claimed.
The Views
The drawings or photographs should contain a
sufficient number of views to completely disclose the
appearance of the claimed design, i.e., front, rear,
right and left sides, top and bottom. While not
required, it is suggested that perspective views be
submitted to clearly show the appearance and shape
of three-dimensional designs. If a perspective view
is submitted, the surfaces shown would normally not
be required to be illustrated in other views if these
surfaces are clearly understood and fully disclosed in
the perspective.
Views that are merely duplicates of other views of
the design or that are merely flat and include no
ornamentality may be omitted from the drawing if
the specification makes this explicitly clear. For
example, if the left and right sides of a design are
identical or a mirror image, a view should be
provided of one side and a statement made in the
drawing description that the other side is identical or
a mirror image. If the bottom of the design is flat, a
view of the bottom may be omitted if the figure
descriptions include a statement that the bottom is
flat and unornamented. The term "unornamented"
should not be used to describe visible surfaces that
United States Patent and Trademark Office
A Guide To Filing A Design Patent Application
include structure that is clearly not flat. In some
cases, the claim may be directed to an entire article,
but because all sides of the article may not be visible
during normal use, it is not necessary to disclose
them. A sectional view which more clearly brings
out elements of the design is permissible, however a
sectional view presented to show functional features,
or interior structure not forming part of the claimed
design, is neither required nor permitted.
Surface Shading
The drawing should be provided with appropriate
surface shading which shows clearly the character
and contour of all surfaces of any three-dimensional
aspects of the design. Surface shading is also
necessary to distinguish between any open and solid
areas of the design. Solid black surface shading is
not permitted except when used to represent the color
black as well as color contrast. Lack of appropriate
surface shading in the drawing as filed may render
the shape and contour of the design nonenabling
under 35 U.S.C. 112, first paragraph. Additionally, if
the shape of the design is not evident from the
disclosure as filed, addition of surface shading after
filing may be viewed as new matter. New matter is
anything that is added to, or from, the claim,
drawings or specification, that was neither shown nor
suggested in the original application (see 35 U.S.C.
132 and 37 CFR § 1.121, at the end of this guide).
Broken Lines
A broken line disclosure is understood to be for
illustrative purposes only and forms no part of the
claimed design. Structure that is not part of the
claimed design, but is considered necessary to show
the environment in which the design is used, may be
represented in the drawing by broken lines. This
includes any portion of an article in which the design
is embodied or applied to that is not considered part
of the claimed design. When the claim is directed to
just surface ornamentation for an article, the article in
which it is embodied must be shown in broken lines.
In general, when broken lines are used, they should
not intrude upon or cross the showing of the claimed
design and should not be of heavier weight than the
lines used in depicting the claimed design. Where a
broken line showing of environmental structure must
necessarily cross or intrude upon the representation
of the claimed design and obscures a clear
understanding of the design, such an illustration
should be included as a separate figure in addition to
the other figures which fully disclose the subject
matter of the design.
The Oath or Declaration
The oath or declaration required of the applicant
must comply with the requirements set forth in 37
CFR §1.63.
Disclosure Examples
So that the applicant will better understand what
constitutes a complete disclosure, examples of

The Design Patent
Application Process
The preparation of a design patent application and
the conducting of the proceedings in the USPTO to
obtain the patent is an undertaking requiring the
knowledge of patent law and rules and Patent and
Trademark Office practice and procedures. A patent
attorney or agent specially trained in this field is best
able to secure the greatest patent protection to which
applicant is entitled. It would be prudent to seek the
services of a registered patent attorney or agent.
Representation, however, is not required. A
knowledgeable
applicant may
successfully
prosecute his or her own application. However,
while persons not skilled in this work may obtain a
patent in many cases, there is no assurance that the
patent obtained would adequately protect the
particular design.
Of primary importance in a design patent
application is the drawing disclosure, which
illustrates the design being claimed. Unlike a
utility application, where the "claim" describes the
invention in a lengthy written explanation, the
claim in a design patent application protects the
overall visual appearance of
the design,
“described” in the drawings. It is essential that the
applicant present a set of drawings
(or
photographs) of the highest quality which conform
to the rules and standards which are reproduced in
this guide. Changes to these drawings after the
application has been filed, may introduce new
matter, which is not permitted by law (35 U.S.C.
132). It is in applicant's best interest to ensure that
the drawing disclosure is clear and complete prior
to filing the application, since an incomplete or
poorly prepared drawing may result in a fatally
defective disclosure which cannot become a patent.
It is recommended that applicant retain the services
of a professional draftsperson who specializes in
preparing design patent drawings. Examples of
acceptable drawings and drawing disclosures are
included in this Guide so that applicant will have
some idea of what is required and can prepare the
drawings accordingly.
Filing An Application
In addition to the drawing disclosure, certain other
information is necessary. While no specific format is
required, it is strongly suggested that applicant
follow the formats presented to ensure that the
application is complete.
When a complete design patent application, along
with the appropriate filing fee, is received by the
Office, it is assigned an Application Number and a
Filing Date. A "Filing Receipt" containing this
information is sent to the applicant. The application
is then assigned to an examiner. Applications are
examined in order of their filing date.
Examination
The actual “examination” entails checking for
compliance with formalities, ensuring completeness
of the drawing disclosure and a comparison of the
claimed subject matter with the “prior art.” “Prior
art” consists of issued patents and published
materials. If the claimed subject matter is found to
be patentable, the application will be “allowed,” and
instructions will be provided to applicant for
completing the process to permit issuance as a patent.
The examiner may reject the claim in the application
if the disclosure cannot be understood or is
incomplete, or if a reference or combination of
references found in the prior art, shows the claimed
design to be unpatentable. The examiner will then
issue an Office action detailing the rejection and
addressing the substantive matters which effect
patentability.
This Office action may also contain suggestions by
the examiner for amendments to the application.
Applicant should keep this Office action for his or
her files, and not send it back to the Office.
Response
If, after receiving an Office action, applicant elects to
continue prosecution of the application, a timely
reply to the action must be submitted. This reply
should include a request for reconsideration or
further examination of the claim, along with any
amendments desired by the applicant, and must be in
writing. The reply must distinctly and specifically
point out the supposed errors in the Office action and
must address every objection and/or rejection in the
action. If the examiner has rejected the claim over
prior art, a general statement by the applicant that the
United States Patent and Trademark Office
A Guide To Filing A Design Patent Application
claim is patentable, without specifically pointing out
how the design is patentable over the prior art, does
not comply with the rules.
In all cases where the examiner has said that a reply
to a requirement is necessary, or where the examiner
has indicated patentable subject matter, the reply
must comply with the requirements set forth by the
examiner, or specifically argue each requirement as
to why compliance should not be required.
In any communication with the Office, applicant
should include the following items:
1. Application number (checked for accuracy).
2. Group art unit number (copied from filing
receipt or the most recent Office action).
3. Filing date.
4. Name of the examiner who prepared the most
recent Office action.
5. Title of invention.
It is applicant's responsibility to make sure that the
reply is received by the Office prior to the expiration
of the designated time period set for reply. This time
period is set to run from the “Date Mailed,” which is
indicated on the first page of the Office action. If the
reply is not received within the designated time
period,
the application will be considered
abandoned. In the event that applicant is unable to
reply within the time period set in the Office action,
abandonment may be prevented if a reply is filed
within six months from the mail date of the Office
action provided a petition for extension of time and
the fee set forth in 37 CFR § 1.17(a) are filed. The
fee is determined by the amount of time requested,
and increases as the length of time increases. These
fees are set by Rule and could change at any time.
An “Extension of Time” does not have to be
obtained prior to the submission of a reply to an
Office action; it may be mailed along with the reply.
See insert for schedule of current fees. Note: an
extension of time cannot be obtained when
responding to a “Notice of Allowance.”
To ensure that a time period set for reply to an Office
action is not missed; a “Certificate of Mailing”
should be attached to the reply. This “Certificate”
establishes that the reply is being mailed on a given
date. It also establishes that the reply is timely, if it
was mailed before the period for reply had expired,
and if it is mailed with the United States Postal
Service. A “Certificate of Mailing” is not the same
as “Certified Mail.” A suggested format for a
Certificate of Mailing is as follows:
“I hereby certify that this correspondence is being
deposited with the United States Postal Service as
first class mail in an envelope addressed to: Box
Design, Commissioner for Patents, Washington, D.C.
20231, on (DATE MAILED)”

If a receipt for any paper filed in the USPTO is
desired, applicant should include a stamped, self-
addressed postcard, which lists, on the message side
applicant's name and address, the application
number, and filing date, the types of papers
submitted with the reply (i.e., 1 sheet of drawings, 2
pages of amendments, 1 page of an oath/declaration,
etc.) This postcard will be stamped with the date of
receipt by the mailroom and returned to applicant.
This postcard will be applicant's evidence that the
reply was received by the Office on that date.
If applicant changes his or her mailing address after
filing an application, the Office must be notified in
writing of the new address. Failure to do so will
result in future communications being mailed to the
old address, and there is no guarantee that these
communications will be forwarded to applicant's new
address. Applicant's failure to receive, and properly
reply to these Office communications will result in
the application being held abandoned. Notification
of “Change of Address” should be made by separate
letter, and a separate notification should be filed for
each application.
Reconsideration
Upon submission of a reply to an Office action, the
application will be reconsidered and further
examined in view of applicant's remarks and any
amendments included with the reply. The examiner
11
A Guide To Filing A Design Patent Application
United States Patent and Trademark Office
12
will then either withdraw the rejection and allow the
application or, if not persuaded by the remarks and/or
amendments submitted, repeat the rejection and
make it Final. Applicant may file an appeal with the
Board of Patent Appeals and Interferences after
given a final rejection or after the claim has been
rejected twice. Applicant may also file a new
application prior to the abandonment of the original
application, claiming benefit of the earlier filing date.
This will allow continued prosecution of the claim.
Drawing Examples
The two types of shading commonly employed in
design patent application drawings are straight-line
surface shading and stippling. Individually or in
combination, they can effectively represent the
character and contour of most surfaces.

Graphical symbols for conventional elements may be
used on the drawing when appropriate, subject to
approval by the Office. The symbols that follow
have been approved for such use. This collection does
not purport to be exhaustive; other standard and
commonly used symbols will also be acceptable
provided they are clearly understood, are adequately
identified in the specification as filed, and do not
create confusion with other symbols used in
patent drawings.
NOTES: In general, in lieu of a symbol, a
conventional element, combination or circuit may be
shown by an appropriately labeled rectangle, square
or circle; abbreviations should not be used unless
their meaning is evident and not confusing with the

35 U.S.C. 102 Conditions for patentability;
novelty and loss of right to patent
A person shall be entitled to a patent unless -
(a) the invention was known or used by others in
this country, or patented or described in a printed
publication in this or a foreign country, before the
invention thereof by the applicant for patent, or
(b) the invention was patented or described in a
printed publication in this or a foreign country or
in public use or on sale in this country, more than
one year prior to the date of the application for
patent in the United States,
or
(c) he has abandoned the invention,
or
(d) the invention was first patented or caused to
be patented, or was the subject of an inventor's
certificate, by the applicant or his legal
representatives or assigns in a foreign country
prior to the date of the application for patent in
this country on an application for patent or
inventor's certificate filed more than twelve
months before the filing of the application in the
United States,
or
(e) the invention was described in-
(1)an application for patent, published under
section 122(b), by another filed in the United
States before the invention by the applicant for
patent, except that an international application
filed under the treaty defined in section 351(a)
shall have the effect under this subsection of a
national application published under section
122(b) only if the international application
designating the United States was published
under Article 21(2)(a) of such treaty in the
English language; or
(2)a patent granted on an application for patent
by another filed in the United States before the
invention by the applicant for patent, except
that a patent shall not be deemed filed in the
United States for the purposes of this
subsection based on the filing of an
international application filed under the treaty
defined in section 351(a);
or
(f) he did not himself invent the subject matter
sought to be patented,
or
(g) (1) during the course of an interference
conducted under section 135 or section 291,
another inventor involved therein establishes, to
the extent permitted in section 104, that before
such person's invention thereof the invention was
made by such other inventor and not abandoned,
suppressed, or concealed, or (2) before such
person's invention thereof, the invention was
made in this country by another inventor who had
not abandoned, suppressed, or concealed it. In
determining priority of invention under this
subsection, there shall be considered not only the
respective dates of conception and reduction to
practice of the invention, but also the reasonable
diligence of one who was first to conceive and
last to reduce to practice, from a time prior to
conception by the other.
35 U.S.C. 103 Conditions for patentability; non-
obvious subject matter
(a) A patent may not be obtained though the
invention is not identically disclosed or described
as set forth in section 102 of this title, if the
differences between the subject matter sought to
be patented and the prior art are such that the
subject matter as a whole would have been
obvious at the time the invention was made to a
19
Patent Laws That Apply to Design Patent Applications
A Guide To Filing A Design Patent Application
United States Patent and Trademark Office
20
person having ordinary skill in the art to which
said subject matter pertains. Patentability shall
not be negatived by the manner in which the
invention was made.
(b) (1) Notwithstanding subsection (a), and upon
timely election by the applicant for patent to
proceed under this subsection, a biotechnological
process using or resulting in a composition of
matter that is novel under section 102 and
nonobvious under subsection (a) of this section
shall be considered nonobvious if-
(A) claims to the process and the composition
of matter are contained in either the same
application for patent or
in separate
applications having the same effective filing
date;
and
(B) the composition of matter, and the process
at the time it was invented, were owned by the
same person or subject to an obligation of
assignment to the same person.
(2) A patent issued on a process under paragraph (1)-
(A) shall also contain the claims to the
composition of matter used in or made by
that process,
or
(B) shall, if such composition of matter is
claimed in another patent, be set to expire on
the same date as such other patent,
notwithstanding section 154.
(3) For purposes of paragraph (1), the term
“biotechnological process” means-
(A) a process of genetically altering or
otherwise inducing a single- or multi-celled
organism to-
(i) express an exogenous nucleotide
sequence,
(ii) inhibit, eliminate, augment, or alter
expression of an endogenous nucleotide
sequence,
or
(iii) express a specific physiological
characteristic not naturally associated with
said organism;
(B) cell fusion procedures yielding a cell line
that expresses a specific protein, such as a
monoclonal antibody;
and
(C) a method of using a product produced by a
process defined by subparagraph (A) or (B), or
a combination of subparagraphs (A) and (B).
(c) Subject matter developed by another person,
which qualifies as prior art only under one or
more of subsections (e), (f), and (g) of section 102
of this title, shall not preclude patentability under
this section where the subject matter and the
claimed invention were, at the time the invention
was made, owned by the same person or subject
to an obligation of assignment to the same person.
35 U.S.C. 112 Specification
The specification shall contain a written description
of the invention, and of the manner and process of
making and using it, in such full, clear, concise, and
exact terms as to enable any person skilled in the art
to which it pertains, or with which it is most nearly
connected, to make and use the same, and shall set
forth the best mode contemplated by the inventor of
carrying out his invention.
The specification shall conclude with one or more
claims particularly pointing out and distinctly
claiming the subject matter, which the applicant
regards as his invention.
A claim may be written in independent or, if the
nature of the case admits, in dependent or multiple
dependent form.
Subject to the following paragraph, a claim in
dependent form shall contain a reference to a claim
previously set forth and then specify a further
limitation of the subject matter claimed. A claim in
dependent form shall be construed to incorporate by
reference all the limitations of the claim to which it
refers.
A claim in multiple dependent form shall contain a
reference, in the alternative only, to more than one
claim previously set forth and then specify a further
limitation of the subject matter claimed. A multiple
dependent claim shall not serve as a basis for any
other multiple dependent claim. A multiple
dependent claim shall be construed to incorporate by
reference all the limitations of the particular claim in
relation to which it is being considered.
United States Patent and Trademark Office
A Guide To Filing A Design Patent Application
An element in a claim for a combination may be
expressed as a means or step for performing a
specified function without the recital of structure,
material, or acts in support thereof, and such claim
shall be construed to cover the corresponding
structure, material, or acts described in the
specification and equivalents thereof.
35 U.S.C. 132 Notice of rejection; reexamination
(a) Whenever, on examination, any claim for a patent
is rejected, or any objection or requirement made, the
Director shall notify the applicant thereof, stating the
reasons for such rejection, or objection or
requirement, together with such information and
references as may be useful in judging of the
propriety of continuing the prosecution of his
application; and if after receiving such notice, the
applicant persists in his claim for a patent, with or
without amendment, the application shall be
reexamined. No amendment shall introduce new
matter into the disclosure of the invention.
(b) The Director shall prescribe regulations to
provide
for
the continued examination of
applications for patent at the request of the applicant.
The Director may establish appropriate fees for such
continued examination and shall provide a 50 percent
reduction in such fees for small entities that qualify
for reduced fees under section 41(h)(1) of this title.
35 U.S.C. 171 Patents for designs
Whoever invents any new, original, and ornamental
design for an article of manufacture may obtain a
patent therefor, subject to the conditions and
requirements of this title.

37 CFR 1.76 Application data sheet
(a) Application data sheet. An application data sheet
is a sheet or sheets that may be voluntarily submitted
in either provisional or nonprovisional applications,
which contains bibliographic data, arranged in a
format specified by the Office. If an application data
sheet is provided, the application data sheet is part of
the provisional or nonprovisional application for
which it has been submitted.
(b) Bibliographic data. Bibliographic data as used in
paragraph (a) of this section includes:
(1) Applicant information. This information
includes the name, residence, mailing address,
and citizenship of each applicant (§ 1.41(b)). The
name of each applicant must include the family
name, and at least one given name without
abbreviation together with any other given name
or initial. If the applicant is not an inventor, this
information also includes the applicant' s
authority (§§ 1.42, 1.43, and 1.47) to apply for the
patent on behalf of the inventor.
(2) Correspondence information. This informa-
tion includes the correspondence address, which
may be indicated by reference to a customer
number, to which correspondence is to be directed
(see § 1.33(a)).
(3) Application information. This information
includes the title of the invention, a suggested
classification, by class and subclass, the
Technology Center to which the subject matter of
the invention is assigned, the total number of
drawing sheets, a suggested drawing figure for
publication (in a nonprovisional application), any
docket number assigned to the application, the
type of application (e.g., utility, plant, design,
reissue, provisional), whether the application
23
A Guide To Filing A Design Patent Application
United States Patent and Trademark Office
24
discloses any significant part of the subject matter
of an application under a secrecy order pursuant
to § 5.2 of this chapter (see § 5.2(c)), and, for
plant applications, the Latin name of the genus
and species of the plant claimed, as well
as the variety denomination. The suggested
classification and Technology Center information
should be supplied for provisional applications
whether or not claims are present. If claims are
not present in a provisional application, the
suggested classification and Technology Center
should be based upon the disclosure.
(4) Representative information. This information
includes the registration number of each
practitioner having a power of attorney or
authorization of agent in the application
(preferably by reference to a customer number).
Providing this information in the application data
sheet does not constitute a power of attorney or
authorization of agent in the application (see
§ 1.34(b)).
(5) Domestic priority information.
This
information includes the application number, the
filing date, the status (including patent number if
available), and relationship of each application
for which a benefit is claimed under 35 U.S.C.
119(e), 120, 121, or 365(c). Providing this
information in the application data sheet
constitutes the specific reference required by 35
U.S.C. 119(e) or 120, and § 1.78(a)(2) or
§ 1.78(a)(4), and need not otherwise be made part
of the specification.
(6) Foreign priority
information.
This
information includes the application number,
country, and filing date of each foreign
application for which priority is claimed, as well
as any foreign application having a filing date
before that of the application for which priority is
claimed. Providing this information in the
application data sheet constitutes the claim for
priority as required by 35 U.S.C. 119(b) and
§ 1.55(a).
(7) Assignee information. This information
includes the name (either person or juristic entity)
and address of the assignee of the entire right,
title, and interest in an application. Providing this
information in the application data sheet does not
substitute for compliance with any requirement of
part 3 of this chapter to have an assignment
recorded by the Office.
(c) Supplemental
application data
sheets.
Supplemental application data sheets:
(1) May be subsequently supplied prior to
payment of the issue fee either to correct or
update information in a previously submitted
application data sheet, or an oath or declaration
under § 1.63 or § 1.67, except that inventorship
changes are governed by § 1.48, correspondence
changes are governed by § 1.33(a), and
citizenship changes are governed by § 1.63 or
§ 1.67;
and
(2) Should identify the information that is being
changed (added, deleted, or modified) and
therefore need not contain all the previously
submitted information that has not changed.
(d) Inconsistencies between application data sheet
and oath or declaration.
For inconsistencies
between information that is supplied by both an
application data sheet under this section and by an
oath or declaration under §§ 1.63 and 1.67:
(1) The latest submitted information will govern
notwithstanding whether supplied by an
application data sheet, or by a § 1.63 or § 1.67
oath or declaration, except as provided by
paragraph (d)(3) of this section;
(2) The information in the application data sheet
will govern when the inconsistent information is
supplied at the same time by a § 1.63 or § 1.67
oath or declaration, except as provided by
paragraph (d)(3) of this section;
(3) The oath or declaration under § 1.63 or § 1.67
governs inconsistencies with the application data
sheet in the naming of inventors (§ 1.41(a)(1))
and setting forth their citizenship (35 U.S.C. 115);
(4) The Office will initially capture bibliographic
information from the application data sheet
(notwithstanding whether an oath or declaration
governs the information). Thus, the Office shall
generally not look to an oath or declaration under
§ 1.63 to see if the bibliographic information
contained therein
is consistent with
the
bibliographic information captured from an
application data sheet (whether the oath or
declaration is submitted prior to or subsequent to
the application data
sheet).
Captured
bibliographic information derived from an
application data sheet containing errors may be
recaptured by a request therefor and the
United States Patent and Trademark Office
A Guide To Filing A Design Patent Application
submission of a supplemental application data
sheet, an oath or declaration under § 1.63 or §
1.67, or a letter pursuant to § 1.33(b).
37 CFR 1.84
Standards for drawings
(a) Drawings. There are two acceptable categories
for presenting drawings in utility and design patent
applications.
(1) Black ink. Black and white drawings are
normally required. India ink, or its equivalent
that secures solid black lines, must be used for
drawings;
or
(2) Color. On rare occasions, color drawings may
be necessary as the only practical medium by
which to disclose the subject matter sought to be
patented in a utility or design patent application or
the subject matter of a statutory invention
registration. The color drawings must be of
sufficient quality such that all details in the
drawings are reproducible in black and white in
the printed patent. Color drawings are not
permitted in international applications (see PCT
Rule 11.13), or in an application, or copy thereof,
submitted under the Office electronic filing
system. The Office will accept color drawings in
utility or design patent applications and statutory
invention registrations only after granting a
petition filed under this paragraph explaining why
the color drawings are necessary. Any such
petition must include the following:
(i) The fee set forth in § 1.17(h);
(ii) Three (3) sets of color drawings;
(iii) A black and white photocopy that
accurately depicts, to the extent possible, the
subject matter shown in the color drawing;
and
(iv) An amendment to the specification to
insert (unless the specification contains or has
been previously amended to contain) the
following language as the first paragraph of
the brief description of the drawings:
The patent or application file contains at least
one drawing executed in color. Copies of this
patent or patent application publication with
color drawing(s) will be provided by the
Office upon request and payment of the
necessary fee.
(b) Photographs.
(1) Black and white. Photographs, including
photocopies of photographs, are not ordinarily
permitted in utility and design patent applications.
The Office will accept photographs in utility and
design patent
applications,
however,
if
photographs are the only practicable medium for
illustrating the claimed invention. For example,
photographs
or
photomicrographs
of:
electrophoresis gels, blots (e.g., immunological,
western, Southern,
and northern),
auto-
radiographs, cell cultures (stained and unstained),
histological tissue cross sections (stained and
unstained), animals, plants, in vivo imaging, thin
layer
chromatography
plates,
crystalline
structures, and, in a design patent application,
ornamental effects, are acceptable. If the subject
matter of the application admits of illustration by
a drawing, the examiner may require a drawing in
place of the photograph. The photographs must
be of sufficient quality so that all details in the
photographs are reproducible in the printed
patent.
(2) Color photographs. Color photographs will
be accepted in utility and design patent
applications if the conditions for accepting color
drawings and black and white photographs have
been satisfied. See paragraphs (a)(2) and (b)(1)
of this section.
(c) Identification of drawings. Identifying indicia, if
provided, should include the title of the invention,
inventor's name, and application number, or docket
number (if any) if an application number has not
been assigned to the application. If this information
is provided, it must be placed on the front of each
sheet and centered within the top margin.
(d) Graphic forms in drawings. Chemical or
mathematical formulae, tables, and waveforms may
be submitted as drawings and are subject to the same
requirements as drawings. Each chemical or
mathematical formula must be labeled as a separate
figure, using brackets when necessary, to show that
information is properly integrated. Each group of
waveforms must be presented as a single figure, using
a common vertical axis with time extending along the
horizontal axis. Each individual waveform discussed
in the specification must be identified with a separate
letter designation adjacent to the vertical axis.
25

(e) Type of paper. Drawings submitted to the Office
must be made on paper, which is flexible, strong,
white, smooth, non-shiny, and durable. All sheets
must be reasonably free from cracks, creases, and
folds. Only one side of the sheet may be used for the
drawing. Each sheet must be reasonably free from
erasures and must be free from alterations,
overwritings, and interlineations. Photographs must
