patent illustration


We have over 18 years of experience in the preparation of finished drawings that meet the standards of the U.S. Department of Commerce Patent and Trademark Office. At TPA we take great pride in our work and our client service, and we want you to rest assured that your patent illustrations are in a secure environment. We always provide a non-disclosure agreement to our clients for the protection of their patent rights.

We currently work with patent attorneys, patent agents, inventors, and engineers, in the preparation of patent applications in the medical, electronic, mechanical, hydraulic, and electrical fields. With our extensive experience, we are able to develop drawings from a variety of reference materials including pencil sketches, faxes, engineering blueprints, photographs, and prototypes. We have the ability to read and understand engineering prints, but also the flexibility to develop drawings from products that are still in the concept stage.

Our illustrators can supply you with a combination of schematics, isometrics, cross-sections, and cutaways that allow you a variety of ways to describe your product. These drawings can be provided in a PDF format for printing at your location. They can also be formatted for DIN A4 size or 8 1/2" x 11" paper.
