Greg Collins



As an experienced trial lawyer, Greg handles a variety of complex commercial disputes and intellectual property litigation.

Greg works with his clients to obtain the best litigation outcome. And while most intellectual property and commercial litigation disputes resolve short of trial, Greg prepares all of his client’s cases for trial. As lead trial counsel for his clients, Greg has secured multi-million dollar verdicts and arbitration awards in bet-the-company litigation and he has prosecuted and defended cases seeking damage awards in excess of one-hundred million dollars.

Greg’s aggressive approach has proven successful many times over, and has been lauded by independent rating organizations, by other lawyers and most importantly, by Greg’s clients. Greg has been recognized three times by U.S. News & World Reports’ Best Lawyers’ “Lawyer of the Year” in Scottsdale, Arizona for Patent Litigation (an honor bestowed on only one attorney each year). Greg also ranks as a “Southwest Super Lawyer” in intellectual property litigation. And he holds an “AV Preeminent Rating” (the highest possible rating) from Martindale-Hubbell.  

Greg has taught continuing legal education courses to attorneys across the United States and he has served as an adjunct law professor, teaching courses in intellectual property.
