President & Senior Patent Attorney

Before joining the firm in 2013, Stephen (Steve) had over 20 years of experience in the field of intellectual property, including several years working as a patent agent, followed by over 12 years as in-house patent counsel for Fortune 500 companies or their subsidiaries, including 10 years at 3M Company, and then about 6 years in a law firm setting. He has practiced extensively in: patent preparation; U.S. and worldwide patent prosecution, infringement, non-infringement, and product clearance analyses and opinions; client counseling; and litigation support, including discovery, motion practice, and participation in court-ordered mediation sessions in connection with patent infringement litigation.


His worldwide patent prosecution experience includes acting as client representative in opposition and revocation proceedings at the European Patent Office, and in patent infringement hearings that took place in Germany and Italy. He has also prepared numerous non-disclosure agreements, and other agreements including licensing and development agreements, and has resolved trademark issues. Technical subject matter for patent drafting and prosecution includes: multilayered polymer films, including optical films and barrier films; film and web handling systems; extrusion, lamination, molding, and embossing techniques; backlit displays and other displays; LED devices and other optical components; micromachining and microreplication; cardiac pacemakers and other medical devices; magnetic disk drives; flow sensors; laboratory analytical equipment; audio systems and devices; and software apps.


Before his legal career, he worked as an engineer for 6 years developing and investigating optically-based pressure, temperature, flow, and analytical sensors. This included hands-on familiarity in an optics laboratory with technologies including: fiber optics and other optical waveguides; lens and prism design; fluorescence; lasers, laser diodes, LEDs, and other solid-state light sources; silicon photodetectors and other photodetectors; optical filters; spectrometers and interferometers; blackbody design and calibration; electronic equipment including transimpedance amplifiers, lock-in amplifiers, and digital and analog oscilloscopes; digital and analog signal processing; clean room wafer fabrication and inspection processes, including photolithography and chemical etching; workstation design including computer-automated data acquisition and control; programmable ovens; and software development.
