Patent drawing refers to a detailed illustration of the invention that is submitted during the Patent application procedure. The USPTO (United States Patent and Trademark Office) demands the patentee to submit detailed Drawings about the invention with the Patent application. It helps the examiner to understand the making and working of the Invention easily. It is necessary for the Inventor to describe the Invention in the best possible way during the process of drafting Patent application.
Moreover, the examiners may reject the application if the Inventor fails to describe the invention clearly. Patent drawing helps the Inventor in such a scenario. It contains every minute detail that the Inventor might skip in the written documentation. The most efficient way to create a perfect set of drawings is to hire an experienced professional.
