Many rejections received by applicants during the prosecution of a design patent application involve inconsistencies in the drawings. Design patents require a sufficient number of views to completely disclose the appearance of the invention. Most design patents require seven (7) views of the invention – front, rear, top, bottom, right side, left side, and at least one perspective view. These views must be consistent with each other so a full understanding of the design can be reached. Elements shown in each figure should be shown in all others, assuming that the element can be seen in that particular view. Solid and broken lines should be consistent as well. This is one reason it is critical to have a draftsperson who is experienced at design patent drawings.
