Patent Agent and Freelance Writer


With twenty years of experience in aerospace engineering and several as a technically-oriented attorney, plus a background in patent prosecution and in writing nonfiction articles, I am ready to assist with your writing needs.

My Services
Patent Prosecution

As a registered U.S. patent agent (Reg. No. 39736), I have experience in all phases of patent prosecution, from initial filing through issuance. See my writing samples: Application, Amendment.


My articles have been published by GrindTV, Drift Surfing, Mpora Action Sports, Medium, the San Diego Reader, SLO City News and The Inertia. In addition, I've blogged about surfing on my wave journal.

Technical Writing

While working for more than 20 years as an aerospace mechanical engineer, I wrote many technical procedures, specifications, reports and other documents.
