Patent Trial and Appeal Board Pro Bono Program for independent inventors

PTAB Pro Bono logo

Inventors that meet certain financial thresholds and other criteria may be eligible for free legal assistance when appearing before the Patent Trial and Appeal Board (PTAB). The PTAB Pro Bono Program matches volunteer patent professionals with financially under-resourced inventors to provide free legal assistance in preparing ex parte appeals to the PTAB. The PTAB Pro Bono Program is administered by the PTAB Bar Association.

How inventors can apply for assistance

The PTAB Bar Association is the clearinghouse for this program. In this role, the PTAB Bar Association (clearinghouse) will review completed applications to determine if the applicant meets the eligibility qualifications and any additional requirements for the program. If the clearinghouse determines that the applicant satisfies all the eligibility requirements, then the clearinghouse will attempt to match the applicant with a volunteer attorney. The clearinghouse itself does not provide legal advice or representation.

The size and scope of this program is limited, and the clearinghouse may not have a suitable volunteer available for every qualified applicant. Qualifying for the program does not guarantee that the applicant will receive representation.

Please visit the PTAB Bar Association for more information on applying for ex parte appeal assistance.

How patent practitioners can volunteer

Registered patent practitioners are critical to the success of the PTAB Pro Bono Program. If you are a patent practitioner interested in volunteering your legal services, please complete an online volunteer application form.
