David V.H. Cohen


David Cohen is an experienced attorney in patent prosecution and IP transactions who joined the AEON Law team in October 2017.

He helps clients develop and implement their IP strategy by securing legal protection for their inventions, advising on intellectual property portfolio assets, and concluding deals that turn innovation into revenue. His background includes a decade and a half of experience in patent prosecution and copyright transactions.

David’s patent procurement and counseling practice at AEON Law (and previously at Perkins Coie) emphasizes obtaining patent protection for client inventions and assessing IP portfolios for computer-related technology, both for established enterprises and for emerging companies.

David also has substantial experience drafting IP licenses and negotiating commercial transactions for technology-oriented companies and entrepreneurs. Before joining the patent bar, he owned and managed a firm serving early-stage startups, large software companies, and public corporations. He began his professional career as an attorney in the Technology and Intellectual Property department of Preston Gates & Ellis, where he created complex software development and copyright licensing agreements, advised clients on their participation in industry standards organizations, and provided time-sensitive guidance on e-commerce law and cutting-edge legal issues.

David lives in Seattle, his home base for dancing, sailing, and discovering.
