As mentioned last time, design patents protect only the ornamental characteristics of the design, which are the features shown in solid lines in the figures of the design patent application. Therefore, good quality drawings are essential, as they define the bounds of what exactly is protected. The design patent Examiner will require good quality drawings in order to grant the patent, but the quality of the drawings will also be important down the road if and when the scope of the patent is determined and the particular design being protected is interpreted. Use of a draftsperson that is familiar with the drawing requirements associated with design applications is essential. I often have engineers ask if they can prepare their own drawings. I allow this with utility applications but I required an experienced design patent draftsperson who has experience with design patents.
