Our Firm

Carstens & Cahoon is an intellectual property law firm based in Dallas, Texas. We are trusted legal advisors to some of the world’s leading companies, brightest entrepreneurs, and innovation investors.

Patent attorneys David Carstens and Colin Cahoon founded Carstens & Cahoon as an intellectual property firm based in Dallas in 1998. Starting off with only three lawyers and two support staff, Carstens & Cahoon has grown into one of the largest intellectual property law firms in Texas — and the Southwestern United States. The reason for our growth is simple… we are among the best IP attorneys anywhere. We have strong technical experience and years of hands-on experience providing patent services, insight and global execution.

Not every attorney – or even every IP attorney – is qualified to handle patent work. Patent attorneys are a rare breed that combines top-notch technical skills and legal insights. In addition to the standard bar exam, our intellectual property attorneys are required to sit for the Patent Bar Exam, which indicates that the attorney has the technical expertise to sit for the exam and has demonstrated proficiency in patent office procedures.
