Bringing Your Invention Alive Through Drawings

By Lisa Velez

As a former patent examiner, one important feature a patent application can have is great drawings of the invention. A patent application typically requires multiple views, including interior and exterior profiles to show not only what can be seen on the outside but what is in the inside. As the old saying goes, “a picture is worth a 1000 words.” This old saying holds true in patent drafting and, especially, during prosecution when negotiating with the United States Patent and Trademark Office (USPTO).

Drawings of a patent application should bring the inventor’s invention alive. A carefully prepared set of drawings should display those features and sometimes variation that are new. These drawings help the patent practitioner direct the examiners attention as well as any future jury to those critical inventive features. Sometimes, an invention is not in a particular element but a combination of elements that are synergized in a new way to produce new acts. Drawings are also needed to capture this synergy.

Drawings are so important when evaluating the patent, as the patent application must show every feature of the invention specified in the claims, pursuant to 37 CFR §1.83. Therefore, investing in a professionally prepared set of drawings is money well spent.
