The patent Drafting process requires great zeal and often a lot of effort. Any ambiguity leftover in drafting a patent application can lead to office action or rejection of the patent application. Patent Diagrams are a great way of saving the applicant from an office action or rejection of patent application. So, rejection proof patent illustrations are one way of making your application more presentable and moving it a step ahead for getting a patent grant.

Patent diagrams should always be included in the patent application in most cases but can be excluded in the application of inventions like chemical methods, reactions, etc. But it is a good practice to add patent drawings in all patent applications regardless of what the claim is. Patent Diagrams are not supposed to be great visuals or the work of art but rather they should depict everything about the invention in detail. A good patent application always includes a handful number of patent diagrams that depict the invention clearly.
