The drawing disclosure is the most important element of the application. Every design patent application must include either a drawing or a photograph of the claimed design. As the drawing or photograph constitutes the entire visual disclosure of the claim, it is of utmost importance that the drawing or photograph be clear and complete, that nothing regarding the design sought to be patented is left to conjecture. The design drawing or photograph must comply with the disclosure requirements of 35 U.S.C. 112, first paragraph. To meet the disclosure requirements of 35 U.S.C. 112, the drawings or photographs must include a sufficient number of views to constitute a complete disclosure of the appearance of the design claimed.
Drawings are normally required to be in black ink on white paper. Photographs, in lieu of drawings, are permitted subject to the requirements of 37 CFR Â§1.84 and Â§1.152.
