Matt Ellsworth is a shareholder with experience in patent drafting, prosecution, and analysis. Matt partners with leading electronics and software companies to develop, enforce and monetize their intellectual property assets. Whether working with small start-ups or globally recognized companies, Matt enjoys helping innovators realize their ideas.

“I love meeting with inventors and getting excited when they’re excited. I also love talking their language, really learning the ins and outs of their innovations, and then translating that into a tangible asset, something they can protect and continue to improve,” he says.

Matt handles many complex electrical and software technologies including telephony, RFID, access control, semiconductors, optics, Artificial Intelligence, communication networks, communication protocols, encryption, web-based business, information storage systems, feedback and control systems, power transmission, power machinery, high current electronics, and low current electronics. He also has experience in non-electrical related technologies such as mechanical patents and business method patents.

Throughout his career, Matt has built a broad network of clients who tend to come back again and again. “My ultimate goal is to be the ‘go-to’ IP person for my clients, big and small. I want them all to feel as though I am just as invested in their IP as they are. It is my goal to provide such a high level of service and attention that everyone involved in the process, from the IP group to each engineer and inventor wants to work with me for the entirety of their career,” he says. It’s a testament to his personalized and creative approach to patent law.

Prior to joining Sheridan Ross, Matt was responsible for the imaging equipment and processes used in a musculoskeletal research laboratory to perform studies as well as organizing and conducting motion studies for patients who had undergone orthopedic surgery. His background in the field, coupled with his academic experience at the Colorado School of Mines, translates to a wide array of technologies, which is something Matt appreciates about his job.

“I had too much curiosity to continue pursuing a career as an engineer. I wanted exposure to as many different technologies and inventions as possible, and I love that my job is now to translate what someone has built into legal language meant to protect their innovation,” he says.
