Irwin IP concentrates on intellectual property and technology-related litigation.  We defend our clients in bet-the-company intellectual property and technology-related matters, and we help our clients enforce and monetize their intellectual property, including through litigation when necessary.


Irwin IP's lawyers have a long history of success in copyright infringement matters, and their experience involves a diverse range of media.  Perhaps the best evidence of Irwin IP's expertise in copyright infringement matters is the fact that when a premier intellectual property law firm was sued for copyright infringement in connection with their patent prosecution procedures, they reached out to Irwin IP founder, Barry Irwin, to handle its defense. Long-time client, Massarelli’s Lawn Ornaments, a leader in the lawn and garden statuary sector, continues to rely upon Irwin IP to protect its valuable designs, and to defend it in copyright matters.  Since Irwin IP was formed, we have successfully handled several copyright infringement matters, including a case involving plagiarism of a frequently-cited medical article, another case involving unauthorized use of a famous photograph, and several music sampling matters for well-known recording artists.

Irwin IP lawyers have successfully protected trade secrets from unlawful misappropriation, and enforced non-compete agreements. In doing so, Irwin IP lawyers not only saved their clients’ businesses, but made new law. 

Irwin IP has also successfully defended its clients against claims of wrongful misappropriation and breach of non-compete agreements, preserving their ability to continue working and selling key product lines. 

As with trademark and advertising matters, non-competition and trade secret matters also often require urgent attention in the form of a preliminary injunction or TRO proceeding. We work around the clock to pursue or defend these matters.

Not only has Irwin IP been retained on these matters, but we have been successful.  For example we have obtained summary judgment of no infringement in two of the defensive matters, and a $16 million jury verdict in the offensive matter.

Irwin IP lawyers have a long history of success in patent infringement matters, including: a complete defense verdict in a $500 million, multi-patent infringement defense; a $16 million jury award in three-week patent infringement trial; a permanent injunction and $7.3 million jury award in an offensive matter protecting a $100-million-dollar-a-year product line; and numerous pre-trial victories.
