Intellectual Property
Brann & Isaacson advises companies, from start-ups to brand-name companies with large trademark and copyright portfolios, on the proper care of their intellectual property. On behalf of these clients, we have litigated patent, trademark, trade dress, and copyright cases in the International Trade Commission and in federal court in over 20 states.
Intellectual Property Litigation
Brann & Isaacson has litigated patent, trademark, trade dress, and copyright cases in the International Trade Commission and in federal court in over 20 states, including the busiest intellectual property districts of the country. In patent matters, the firm defends cases brought by patent trolls and others “monetizing” their patent portfolios. We primarily represent retailers, both large and small, including over a dozen of the 100 largest internet retailers and do not believe that “one size fits all.” Whatever the client’s best interest may be—a joint defense, a go-it-alone strategy; aggressive litigation, a cost-of-defense settlement—will be the path we take.

“Stacy Stitham is an excellent technical lawyer and helps us with discovery and case assessment in patent infringement cases, and Peter Brann helps in negotiating on our behalf both with patent holders and with our indemnitors. They are very practical, no–nonsense lawyers—how to mitigate risk and not get bogged down.”
