  2. 2. Provisional vs. Non Provisional Drawings are the foundation of any patent application, whether it is a provisional or non provisional application. Therefore, it is imperative to abide by the guidelines of the United States Patent and Trademark Office (USPTO) to ensure that the drawings are clear and the patent passes examination. To understanding the differences between the two drawing approaches, we first need to know what provisional and non-provisional patent applications are. Provisional patent application basics: • Provisional patent applications require a low USPTO filing fee and are less expensive than the regular non provisional patent applications. • Provisional patent applications last only for 12 months. You still have to file a non provisional patent application within 12 months of your provisional application in order to retain the advantage of the provisional’s filing date. This is just like filing an extension on your tax return; you still need to pay the taxes and file real tax returns. • Claims are not required for a provisional patent application. • Provisional applications are not examined. A follow-on non provisional goes to the back of the examination line. So if you are racing against time and want your patent issued quickly, a provisional application is not ideal. To be successful, any provisional application must include thorough details of the invention, just as in a non provisional application. Non provisional patent application basics: • A non provisional application establishes the filing date of your patent application and begins the examination process by the USPTO. • Non provisional applications are comprised of a specification (description and claims), an oath or declaration, a drawing (when necessary), and a fee.Legal Advantage
  3. 3. Provisional vs. Non Provisional Patent illustration drawings are critical and can determine the success of any patent application. Therefore, it is important that all drawings are in accordance with USPTO rules. By law, all patent applicants are required to provide a draw- ing of the invention if it increases the understanding of the invention. Exceptions may include for matter compositions or processes where drawings are irrelevant for comprehension. The drawings also differ depending on the type of patent application. • Most drawings for a provisional application are drawn by the inventor or an attorney, and are usually rendered in an unsophisticated manner. • Provisional drawings can be photographs, hand drawings, CAD drawings, or clean line art with hand- drawn numbers and leader lines. • A typical provisional artwork will have the inventor’s signature on it to prove the date of the invention. • Non provisional drawings are usually drawn by an illustrator and filed with an application usually written by a patent attorney. • Non provisional drawings must detail every attribute of the invention specified in the claims. The drawings must adhere to the USPTO’s specifications including paper size, paper type, margin widths, and other details. These explicit details are for overall uniformity when the patent is issued and published. • According to the USPTO, no names or labels are permitted near the drawing. Applicants are expected to use the space in the top margin to identify each sheet of drawings. This identification may consist of the attorney’s name, docket number, the inventor’s name, application number, and/or page numbers.Legal Advantage
