The Design Patent Application: What you need to know
If you decide on a Design Patent Application
If you choose this route, either as an alternative to or in combination with a utility patent application, you need to get professional patent illustrations completed. These need to show the traditional “7 views” of the invention: front, back, top, bottom, right side, left side, and perspective. We urge inventors not to try to do their own patent illustrations unless they are highly proficient in graphics programs AND are fully knowledgeable about USPTO drawing requirements. Professional patent illustrators generally charge $100 to $150 per sheet of drawings, and if your self-created drawings get rejected by USPTO, you will probably pay more in our attorney fees to get them fixed than you would have paid in the first place to have the job done per USPTO guidelines.
