Dilworth & Barrese

Dilworth & Barrese, LLP is excited to announce that we have formed a strategic affiliation with fellow intellectual property firm, Dilworth IP, LLC. With this new affiliation both firms will offer their respective current and future clients a broader array of technical and legal expertise.

The two firms have much in common, beyond just the Dilworth name. Dilworth & Barrese was founded by Peter Dilworth and Rocco Barrese in 1987. Peter is father to Michael Dilworth, Founder and Managing Partner of Dilworth IP.

“Affiliating with my father’s firm is a natural step for us. We have a common history and philosophy, and our respective teams are a great complement to one another. I am very excited to collaborate with the Dilworth & Barrese management including Stephen Barrese and Michael Musella and the rest of the Dilworth & Barrese team. Our clients will continue to benefit from our dedication to exceptional client service with our particular in-house perspective while being able to leverage the shared resources and support resulting from this affiliation,” said Michael Dilworth.

Steve Barrese added, “Michael Dilworth and I have known one another for over 35 years and are both sons of Dilworth & Barrese founders. Both of our firms bring their own unique perspective to this affiliation but share very similar values and the same determination to run a successful IP law firm while maintaining the highest standards of client service. All of us here at Dilworth & Barrese are excited to begin working together with the Dilworth IP team and bringing that shared vision to our clients.”

Both Dilworth & Barrese and Dilworth IP will be retaining their respective names and offices. More information about each firm can be found at https://www.dilworthbarrese.com and www.dilworthip.com.
