Irwin IP concentrates on intellectual property and technology-related litigation.  We defend clients in bet-the-company intellectual property and technology-related matters, and we help our clients enforce and monetize their own intellectual property.  We also handle Patent Office patent validity challenges (reexaminations, IPRs and PGRs), provide intellectual property counseling, and support merger and acquisition due diligence.

“I highly recommend Barry, Reid and team if you have a bet the company intellectual property litigation.   You can count on them to prepare thorough briefs quickly and efficiently.” 

—  David Eisler,

SVP, Chief Legal and Admin. Officer of U.S. Auto Parts Network


Irwin IP was founded in 2014 by Barry Irwin, a twenty-five year veteran of high-stakes intellectual property litigation, decade-long equity partner of one of the most prestigious law firms in the world, and Fellow of the exclusive, invitation-only Litigation Counsel of America trial lawyer honorary society.  Since Barry founded Irwin IP, three of his former "big-law" partners have joined Irwin IP to create an IP litigation boutique with a wealth of high-stakes litigation experience.


Irwin IP is driven by the objective of providing premium legal representation, at reasonable rates, and with billing integrity.  Other firms give lip service to this goal, we live it.  We thoroughly analyze each case, identify winning arguments and the best strategies for presenting them (often unique and creative), zealously prepare the case for trial, and bring matters to closure promptly so your company can get back to business.


We represent a wide variety of clients, from small start-ups to Fortune 500 companies. In the short time since Irwin IP was founded, we have had numerous achievements. For example, we represented a mid-sized software company in a three-week jury trial culminating in a $16 million jury verdict; we proudly helped a small, disruptive start-up defeat patent infringement and false advertising claims asserted by a large, multi-national company; and we achieved summary judgment of no patent infringement (on three separate, independent grounds) for a mid-sized manufacturing company in a hotly contested litigation against its competitor. 


Our philosophy is simple: do what it takes to win, charge reasonable rates for doing so, and do it with integrity.


In response to frequently asked questions, recent developments in intellectual property law, and frequently needed reference materials, Irwin IP has collected and categorized various resource materials.  Although these materials do not constitute legal advice, we do hope you will find these resource materials informative and helpful.
