Are color drawings or photographs allowed in patent applications?
This page is an FAQ based on guidance from the Manual of Patent Examining Procedure. It is provided as guidance, with links to the ground truth sources. This is information only: it is not legal advice.
Color drawings or photographs are generally not allowed in patent applications without special permission. MPEP 507 states:
OPAP may object to and require corrected drawings within a set time period, if the drawings: … (G) contain color drawings or color photographs, but not a petition to accept color drawings/photographs.
If an applicant wishes to include color drawings or photographs, they must file a petition to accept them. It’s important to note that the requirement for a black and white photocopy of color drawings/photographs has been eliminated. Applicants should be prepared to justify the need for color in their drawings or photographs when filing such a petition.
