What are the specific requirements for drawings in design patent applications?

Design patent applications have unique drawing requirements due to their focus on the ornamental design of an article. According to MPEP 608.02(a), the following specific requirements apply:

• Multiple views: The drawings must contain a sufficient number of views to completely disclose the appearance of the design.
• Surface shading: This is often necessary to show the contours and character of the design.
• Solid black surface shading: This is not permitted, except when used to represent the color black or color contrast.
• Broken lines: These may be used to show environmental structure but form no part of the claimed design.
• Color drawings: These are permitted upon filing a petition explaining why color drawings are necessary.

The MPEP states, “Lack of good drawings in a design patent application may result in a refusal to issue the application until suitable drawings are submitted.” Therefore, it’s crucial to submit high-quality, compliant drawings from the outset to avoid delays in the examination process.
