I consider myself an intellectual property law generalist. My law practice has focused since 1989 on preparation and prosecution of patent and trademark applications, legal opinions concerning patent and trademark infringement, validity, and enforceability, transactional work involving intellectual property, such as software licensing, and occasional advice on copyright matters.

On the patents & technology side of my practice, my experience varies over a wide variety of technologies, including carbon capture and sequestration, geothermal energy, oil & gas exploration and production (with emphasis on offshore technology such as managed pressure operations, horizontal well development, and fracturing), combustion technology, glass and glass fiber production, medical devices such as anti-snoring and bruxism reducing oral appliances, wireless communications, cogeneration, syn-gas, drilling fluids, drilling platforms, BOPs, coiled tubing and associated downhole tools, marine geophysical data acquisition, acoustic ranging, water treatment equipment and processes, adhesives, elastomers, ionomers, thermosetting and thermoplastic polymeric materials, plastics (polyethylene, PVC, polypropylene, and the like), polymerization catalysts and processes, consumer items such as bicycle repair racks, commercial cleaning products, abrasives, reflective materials, semiconductors, fiber-optics, cryogenic materials, pulp & paper chemistry, electronic specialty gas purification techniques for semiconductor production, carbon nanotube technology, molecular sieves, heat transfer fluids, fluorinated chemicals, and many others.

Regarding trademarks, I have a considerable trademark docket, and enjoy helping clients choose protectable marks, and avoid problems with third party marks.

I have maintained a private practice since 2003, and previously served as in house counsel to 3M in St. Paul, and Air Liquide in Houston, as an associate with Townsend & Townsend (now Kilpatrick Townsend) in San Francisco, and of counsel with Winstead PC in The Woodlands/Houston. I formerly consulted on chemical patents for the JL Salazar Law Firm.

Prior to my law career, I worked as a process engineer, operations engineer, and inspection engineer for Unocal Corp. (now part of Chevron).
