Brian has over twenty-six years of legal experience in the fields of patent litigation, commercial litigation, licensing, and proceedings before the Patent Office.  In addition to the Eastern and Northern Districts of Texas, Brian has been significantly involved as trial counsel in many patent cases in jurisdictions throughout the country, including the D. Delaware, N.D. California, D. Colorado, D. Utah, S.D. Florida, E.D. Michigan, and D. Massachusetts. These cases have involved technologies ranging from complex digital electronics and computer architectures to less complex mechanical devices.  


Brian successfully resolved numerous patent litigations, including a jury trial, with positive results for VIA Technologies, Inc., a chipset and microprocessor manufacturer.  Over a period of seven years, Brian represented Brookstone in a variety of intellectual property matters, including the negotiation of a creative solution to end multiple litigations between Brookstone and Sharper Image.  Brian represented Gateway, Inc. through trial in the District of Utah in a case concerning an Input/Output controller chip.  Brian successfully resolved numerous patent litigation matters for StoneAge, Inc., an employee-owned company that manufacturers rotary hydraulic tools.  In 2000, Brian negotiated a creative three-party agreement that resolved over ten years of litigation in favor of his client and patent owner, Fischer Imaging Corp., a manufacturer of medical imaging devices, which received $32 million.  Examples of other representations are shown below, which are only a small portion of the at least four hundred cases in which Brian has appeared.  


As a result of these representations, Brian has extensive technical knowledge of a broad range of technologies.  Examples of these technologies include computer chips and architectures, semiconductor manufacturing, networking devices and protocols (the 802.x family, TCP/IP, Bluetooth), telecommunications systems (3G and 4G/LTE), materials (metallurgy and polymers), data storage, gas turbines, robotics, cameras and medical imaging technologies, high voltage power transmission, electronic packaging, satellite set-top box TV receivers, and GPS devices. 


In addition to patent litigation, Brian has handled numerous other types of commercial disputes involving all forms of IP, including copyrights and trademarks, as well as business litigation cases involving breach of contract, antitrust, trade secret, unfair competition and other business torts.  Recently, Brian became a Certified Information Privacy Professional (“CIPP”) through the International Association of Privacy Professionals (“IAPP”), and offers advice to clients regarding cybersecurity and privacy issues. 


Transactional experience includes licensing, patent prosecution, post-grant proceedings, and assisting corporate attorneys in performing IP due diligence in connection with mergers and acquisitions.


Prior to his legal career, Brian practiced engineering at Southwest Research Institute where he designed a robotic arm and related tools to perform maintenance on high voltage power lines, packaging for an automotive computer system, and an undersea fiber optic cable for use in off-shore drilling.  Brian also interned at IBM and Texas Instruments where he supported robotic manufacturing lines for electronic circuit boards.

Brian enjoys snow skiing, biking, fly-fishing, hunting, landscape photography, scuba diving, and studying history.
