After wrapping up our November Patent Illustration CLE: Best Practices in Patent Illustration, I am left with a very strong message: Consistency Counts. The USPTO has official regulations, but at the end of the day a person is examining your application and you need to keep them convinced. By simply keeping your illustrations consistent throughout the application, you can prevent concerned reexaminations. Patent illustrations are drawn in a variety of styles, fonts, line weights, arrows etc and this is one of those situations where style does count. When dealing with a design patent with a series of embodiments, these simple visual cues can leave a lasting impact and by keeping the patent illustration style consistent, you will have a stronger chance of getting approved.
