Patent Law FAQ
This FAQ answers all your questions about patent law, patent procedure, and the patent examination process.
Here’s the complete FAQ:
MPEP 300 - Ownership and Assignment (2)
There are three main ways to submit a patent assignment document to the USPTO:
- Mail: Documents can be mailed to the address specified in 37 CFR 3.27: Mail Stop Assignment Recordation Services, Director of the United States Patent and Trademark Office, P.O. Box 1450, Alexandria, Virginia 22313-1450.
- Fax: Documents can be submitted via facsimile, as outlined in MPEP 302.09. However, certain documents cannot be faxed, such as assignments submitted with new applications.
- Electronic Submission: Documents can be submitted electronically through the Electronic Patent Assignment System (EPAS) as described in MPEP 302.10.
Each method has specific requirements and limitations, so it’s important to review the relevant MPEP sections or consult the USPTO website for detailed instructions.
Can I submit color documents via facsimile for patent assignments?
Submitting color documents via facsimile for patent assignments is not recommended. The MPEP 302.09 states:
“Assignments and other documents affecting title to applications, patents, and registrations that include color drawings or color photographs cannot be recorded by facsimile transmission.”
This restriction is due to the limitations of facsimile technology in accurately reproducing color. To ensure the integrity and legibility of color documents:
- Submit original color documents in person or by mail to the USPTO.
- Use the Electronic Patent Assignment System (EPAS) for electronic submissions that may include color elements.
- If color is not essential to the document, consider converting it to black and white before faxing.
Always verify the current USPTO guidelines for document submission, as procedures may be updated over time.

MPEP 500 - Receipt and Handling of Mail and Papers (3)
A self-addressed postcard serves as a receipt and provides evidence of the items submitted to the USPTO with a patent application. According to MPEP 503, the postcard should itemize all components of the application, including:
- Inventor’s name(s)
- Title of invention
- Number of pages of specification, claims, and sheets of drawing
- Whether the inventor’s oath or declaration is included
- List of additional forms included
- Amount and manner of paying the fee
The MPEP states: “A postcard receipt which itemizes and properly identifies the items which are being filed serves as prima facie evidence of receipt in the USPTO of all the items listed thereon on the date stamped thereon by the USPTO.”
It’s important to note that the postcard must be properly itemized to serve as evidence of receipt. Simply listing “a complete application” is not sufficient. Each component should be specifically listed on the postcard.
For applications filed via EFS-Web, an Electronic Acknowledgment Receipt serves as the electronic equivalent of a postcard receipt.

Yes, you can hand-carry certain documents to the USPTO, but there are specific guidelines and limitations. According to MPEP 501:
Patent-related papers may be hand-carried to the Office in Alexandria, VA. Correspondence cannot be hand-carried to the Regional Offices. If the correspondence is hand-carried to the Office, with limited exceptions (see MPEP § 502, subsection III) it must be delivered to:
United States Patent and Trademark Office
Customer Service Window
Randolph Building
401 Dulany Street
Alexandria, VA 22314
For trademark-related papers, there is a separate location:
Trademark-related papers may be filed at the “walk-up” window located in the Trademark Assistance Center, Madison East, Concourse Level, Room C55, 600 Dulany Street, Alexandria, VA 22314.
It’s important to note that while hand-carrying documents is possible, electronic filing is often faster and more efficient for most types of correspondence with the USPTO.

No, color drawings cannot be submitted by facsimile to the USPTO. This is explicitly stated in MPEP 502.01 and 37 CFR 1.6(d)(4):
Facsimile transmissions are not permitted and, if submitted, will not be accorded a date of receipt in the following situations: … (4) Color drawings submitted under §§ 1.81, 1.83 through 1.85, 1.152, 1.165, 1.173, 1.437, or 1.1026;
The prohibition on faxing color drawings is due to the limitations of facsimile technology in accurately reproducing colors. Submitting color drawings via fax could result in loss of quality or details that are crucial for the proper examination and understanding of the invention.
If you need to submit color drawings for your patent application, you should use other approved methods, such as mailing or electronic filing through the USPTO’s electronic filing system (EFS-Web or Patent Center). Always refer to the most current USPTO guidelines for submitting color drawings to ensure compliance with their requirements.

The submission of biological material specimens to the USPTO is governed by specific requirements outlined in MPEP 608.03(a). The key points are:
- Proper packaging: Specimens must be submitted in containers that ensure their safe delivery.
- Identification: Each specimen should be clearly identified with the inventor’s name, the application number, and the filing date.
- Compliance with regulations: Submissions must comply with all applicable regulations, including those related to dangerous materials and biotechnology inventions.
The MPEP specifically states:
‘Biological specimens will not be returned to the applicant. The procedures for submittal of samples of biological materials for deposit in a suitable depository for patent purposes are governed by 37 CFR 1.801 – 1.809.’
It’s crucial for applicants to follow these guidelines to ensure proper handling and consideration of their biological material specimens during the patent examination process.

Yes, you can submit a working model of your invention to the USPTO, but it’s generally not required unless specifically requested by the examiner. According to MPEP 608.03(a):
‘Models or exhibits are not required in most patent applications since the description of the invention in the specification and the drawings must be sufficiently full, clear, and complete and capable of being understood to disclose the invention without the aid of a model.’
However, there are situations where a model might be beneficial or required:
- If the examiner determines that a model is necessary to understand the invention.
- In applications involving perpetual motion devices, where a working model is required.
- When you believe a model would substantially improve the understanding of your invention.
If you decide to submit a model, ensure it complies with USPTO size and safety requirements, and follow the proper procedures for submission as outlined in the MPEP.
