Welcome to Schaffer Patent Illustration (SPI)

We have specialized in patent and trademark drawings since 1997. Our drawings can be seen in thousands of issued patents worldwide. We have prepared formal drawings for corporations such as Intel, Sun Microsystems, Yahoo, Apple Computer, IBM and many more. We work with Intellectual Property Law firms all around the country.

We have clients in California, Oregon, Washington, Arizona, Texas, Missouri, Pennsylvania and Virginia. We also work with independent Patent Attorneys, Patent Agents and Inventors.

We pride ourselves on turning those rough sketches into high quality, publishable computer drawings. We always prepare our patent drawings to meet all USPTO requirements.
In addition, we can provide formal drawings for the PCT or any foreign country. Utilizing the Internet, we can process all business electronically. We convert all our drawings into one multipage PDF file. You will be able to view and print our drawings from your computer. We can provide hard and soft copies via FedEx or U.S. Mail if requested.

Thank you so much for visiting! Please click on the portfolio link to see some of our work.
