Profile bio

About David Henn

Educated as an aerospace engineer and a lawyer, working as a patent attorney.After receiving my undergrad in Aerospace Engineering (1990), I worked for the Patent Office for three years. During my time at the Office, I took the Patent Bar (1992), and after I left the Office for law school (1993), I became a Patent Agent (1994). While in law school, I worked for the SUNY Research Foundation and a Rochester law firm, Eugene Stephens & Associates (which became part of Brown & Michaels for some time), which I later joined full time (1996). In 2000, I shifted to in-house practice at Xerox, then, following economic hard times for Xerox in 2003, became an independent contracting patent lawyer until the start of my position at Cantor Colburn LLP (2008), which was cut short by the recession. In 2010, I began working with Hoffman Warnick LLC, based in Albany, but in 2013 moved in-house to be General Patent Counsel at Key Systems, Inc. In October 2022, my affiliation with Key Systems was dissolved, and after a short job search, I was and am happy to accept an offer to rejoin Hoffman Warnick full time as Counsel.Specialties: Representative technologies: power handling equipment/software, gas turbines, electrophotography, MEMS/semiconductor technology and packaging, internet applications, other computer software, optical metrology, electrohydraulic automatic transmission control systems, photolithography, chemical vapor deposition, space vehicle fuel control valves, water purifiers, fire resistant safes, bottling, window/furniture hardware, solgel curing apparatus, laser gun sights, and laser pulse weapons.
