Patent Drawings

Drawings for patent applications are not nearly as sophisticated or complicated as engineering or CAD drawings. They are more like drawings that were prepared in a high school drafting class, with an emphasis on simplicity.

The purpose of your drawings is to clearly illustrate the inventive matter. If they don’t you may be in for some expensive rework or outright rejection causing you to either file a new patent application altogether or file a CIP (Continuation- in-part).

In spite of this warning, there is no need to rush out and learn how to become an expert draftsperson. Nor will you need to purchase any expensive books on the technical aspects of drafting patent drawings because in most cases it’s unnecessary.

Most patent drawings are fairly simple, straightforward perspective and plan views, blow-ups and block diagrams. Most inventors tend to be fairly good at drawing and can prepare them adequately for provisional patent applications. Upon the granting of a patent, formal drawings will be required prior to issuance. To better understand how to prepare patent drawings follow the examples in The Scientific Journal (which is also used as your daily log book) or the examples in From Patent to Profit and Patent Writer.
