Hagens Berman Sobol Shapiro, LLP, a Seattle-based complex litigation firm, is pleased to announce the addition of Mark S. Carlson to its growing intellectual-property (IP) practice.

A seasoned veteran, Mr. Carlson has dedicated his legal practice to intellectual property since 1987. He has handled a full range of intellectual property litigation with a focus on patent infringement disputes, including experience in technologies such as wireless handsets and networks, telematics and wireless services, electronics, software, relational databases and data mining, internet search engines, games, medical devices, and mechanical exercise equipment.

Prior to joining Hagens Berman, Mr. Carlson operated his own practice, The Carlson Law Group. Before that, he practiced in the Patent Litigation Group of Dorsey & Whitney. Prior to that work, he was a partner in the Intellectual Property Litigation Group of Bogle & Gates.

Mr. Carlson is joining a practice group that is dedicated exclusively to representing plaintiffs in intellectual-property issues.

"Since we launched our intellectual-property group earlier this year, we have dramatically exceeded our growth expectations, an indication that the market was looking for a tenacious, results-oriented IP firm that is willing to go toe-to-toe with the largest technology companies and win," said managing partner Steve Berman. "Having Mark join our bourgeoning practice will help us continue our growth while delivering top-flight results for our clients."

"I am excited about the prospect of helping grow this truly dynamic approach to intellectual-property law," Carlson said. "Hagens Berman has a well-earned reputation for being one of the most innovative and successful plaintiff firms, and I am looking forward to helping extend that reputation to the intellectual property field."

Mr. Carlson received his bachelor's degree in history from the University of Washington, and earned his law degree from the University of Puget Sound School of Law, where he graduated cum laude. He has been published in the University of Puget Sound Law Review and has spoken at the Seattle IP Inn of Court on topics involving IP litigation.
