Ryan Chirnomas focuses his practice on patent prosecution before the U.S. Patent and Trademark Office, specializing in biotechnology, pharmaceutical, chemical, and mechanical engineering inventions. Ryan uses effective communication and problem-solving skills in order to help clients obtain strong patent protection in a cost-efficient manner. He is also experienced at the Patent Trial and Appeal Board, where he has successfully advocated for reversal of rejections in numerous ex parte oral hearings. Ryan also provides clients with guidance by preparing freedom-to-operate, non-infringement, and validity opinions.
Specifically, Ryan's practice encompasses a wide range of technologies including:
- Recombinant DNA technologies
- Resin compositions
- Optical fibers and waveguides
- Medical devices
- Engines and transmissions
- Electric motors and pumps
During law school, Ryan worked as a student attorney in the Glushko-Samuelson Intellectual Property Law Clinic at American University’s Washington College of Law, where he applied intellectual property law to the public interest.
Before pursuing a career in intellectual property, Ryan was a researcher at the University of Arizona’s Laboratory of Mammary Gland Biology. During this time, Ryan investigated the influence of environmental toxins on the expression of the BRCA1 gene, a DNA repair gene tied to breast and ovarian cancers, and co-authored three academic papers on this topic.
When not practicing law, Ryan's hobbies and interests include historic automobiles, golfing, and listening to music on vintage hi-fi equipment.
