Darin Gibby is a key partner and member of the firm’s Executive Committee. He was instrumental in launching the Denver office in 1995, and since that time has spearheaded its growth and emergence as the largest patent firm in Denver.

Mr. Gibby has over 20 years of experience and focuses his practice on intellectual property counseling, transactions, and licensing matters as well as patent prosecution. He has extensive experience handling the intellectual property aspects of mergers and acquisitions. He counsels start-ups and small businesses on intellectual property challenges to help maximize their portfolios to make them attractive acquisition targets. In addition, he manages several large patent portfolios for Fortune 500 companies.

Mr. Gibby handles patent prosecution and licensing for clients in a wide range of industries, including software and financial transaction systems, medical devices, drug delivery systems, telecommunications, food products, sporting goods, automotive parts, biotechnology-related devices, and Internet-related technology. He has obtained significant patents on drug delivery systems, insulin formulations, atherectomy and imaging catheters, CPR methods, chemical synthesizing systems, computer peripherals, software, sporting goods, cheese making processes, disk drive heads, baby products, and electro-surgical medical devices. He is experienced in post-grant proceedings, and reexamination and interference procedures, including invalidating a significant patent covering dynamic currency conversion. Mr. Gibby also regularly provides freedom-to-operate opinions, as well as invalidity and noninfringement opinions.

As part of his practice, Mr. Gibby routinely visits the U.S. Patent Office in Alexandria, VA, having interviewed hundreds of cases. His strategy focuses on working with examiners, rather than resorting to the appellate process. As a result, he has a working relationship with numerous examiners across many art units.

Mr. Gibby has received many accolades and is regularly recognized by leading publications for his work in intellectual property law. In the 2015 edition of Chambers USA, he was described as “a top-notch lawyer who has great experience in the patent world and provides very practical advice.” He was ranked No. 1 in intellectual property by Chambers USA in 2015 and the four years immediately preceding. Mr. Gibby was recognized in The Best Lawyers in America® in 2016 and the three years immediately preceding, and he was named a 2014 “Denver Lawyer of the Year” in the area of patent law by The Best Lawyers in America®.

Mr. Gibby was named by Legal Media Group to its 2013 Guide to the World's Leading Patent Practitioners. He was named a Colorado “Super Lawyer” by 5280 Magazine and Super Lawyers magazine in 2006, again in 2016 and the four years immediately preceding, and was also recognized as a Colorado “Top 100 Super Lawyer” in 2014. He was one of eight Denver attorneys to be selected as a 2011 BTI Client Service All-Star. Mr. Gibby was selected as a “Life Science Star” in the 2012, 2013, and 2014 editions of LMG Life Sciences. Law Week Colorado named  Mr. Gibby as Barrister's Best Patent Lawyer in 2010, Colorado's Best Patent Attorney in 2009, and 2008 Lawyer of the Year for expanding the law office by 40 percent. Mr. Gibby was also selected as Barrister's Best in 2013 in the category for Colorado’s Best Intellectual Property Law (non-litigator) by Law Week Colorado.
