They are my go-to IP litigation counsel without regard to size or complexity of the matter."
Former GC, Ranir
"As an artist working in an industry of giants, Barry Irwin became a light of hope for me. I felt as though I had pulled the sword from the stone, and this underdog was no longer standing alone against the powers that be. His precision and dedication remain unsurpassed, and I will always be grateful for the results that he has achieved. My company stands taller today, and I will never forget the integral part that Barry has played in this."

Senior Counsel, Libra Solutions
"Barry supervised my work in a very complex piece of litigation which required him to understand, in addition to the law, the ultimate client's business operations and the intricacies of several relevant generally accepted accounting principles.
