What are the rules for submitting color drawings in a patent application?
Submitting color drawings in a patent application requires special considerations and procedures. According to MPEP 608.02:
“Color drawings are not ordinarily permitted in utility patent applications. The Office will accept color drawings in utility patent applications only after granting a petition filed under this paragraph explaining why the color drawings are necessary.”
To submit color drawings:
- File a petition explaining why color drawings are necessary
- Pay the required petition fee
- Include three sets of color drawings or color photographs
- Amend the specification to include the reference to color drawings
The MPEP further states: “Color photographs will be accepted in utility patent applications if the conditions for accepting color drawings have been satisfied.” It’s important to note that even if the petition is granted, the patent will be printed in black and white unless color printing fees are paid.
For design patent applications, color drawings are generally acceptable without a petition, but specific requirements still apply regarding the quality and format of the drawings.
