Note: Design Patents revolve around the very detailed, complex drawings that are required. As such, these drawing sheets are typically billed at $125 per sheet as opposed to $100 for utility patents. Please see the patent drawing and samples pages for further information and examples. We need very detailed sketches or photos of a prototype, from all angles (front, back, left side, right side, top, bottom, and one perspective view--see the design patent example for all of the views that are required). We can't do the patent drawings without these views, so these photos or sketches, or an actual product sample, are required before we can begin work.
