Areas of Practice

Mr. Randall has nearly 20 years of experience representing clients in a wide variety of intellectual property matters. He has successfully represented clients in patent, trademark, and trade secret disputes in courts throughout the United States and has been involved in complex multijurisdictional matters in which aspects of the litigation were pending before tribunals around the world. He has handled patent interferences, appeals, and trademark opposition/cancellation proceedings before the U.S Patent and Trademark Office. Recently he represented Mag Instrument in a landmark Japanese High Court IP case, resulting in the first-ever product configuration trademark recognized by the court. 

Mr. Randall routinely advises clients in connection with the development and management of worldwide patent and trademark portfolios, as well as product design and the procurement of product configuration trademarks. He has prosecuted hundreds of patents in the United States and throughout Europe, Latin America, Asia, and Africa and is well-versed in the prosecution of patents to withstand the crucible of litigation. Patents that he has prosecuted have been successfully asserted multiple times, including one of the most frequently litigated patents during 2005 to 2007. 

In addition to litigation and prosecution, Mr. Randall's practice includes counseling clients on matters of strategic planning, technology transfer and licensing agreements, litigation avoidance, domain name disputes, and the development, implementation, and maintenance of IP portfolio management programs. Recently, he represented GeoSynFuels in connection with the formation of a joint venture with the Donald Danforth Plant Science Center to commercialize the production of low-cost proteins. He has also recently worked on the formation of a joint venture in Brazil.
