How should color drawings be submitted in patent applications?

Color drawings in patent applications require special handling:

1. A petition for color drawings must be filed with the application.
2. Three sets of color drawings or color photographs must be submitted.
3. The specification must contain the reference to color drawings.

The MPEP 608.02 states: ‘Color drawings are not permitted in design applications. See 37 CFR 1.84(a)(2) and MPEP § 608.02(VIII).’

For utility patents, color drawings may be accepted if they are necessary for the understanding of the invention. However, they are not encouraged due to reproduction costs and potential issues with public access.
