Orrick has added Mark Jansen as a partner in New York, expanding its trademark counseling and disputes capabilities for technology businesses and other companies.
Jansen joins from Fenwick, where he spent 15 years and became a partner in 2021. His practice covers global brand strategy, trademark disputes and the intellectual property aspects of mergers, acquisitions and other strategic transactions.
He advises companies from startups to Fortune 100 businesses and has supported hundreds of brand and product launches. His industry experience includes artificial intelligence, financial technology, blockchain, enterprise software, hardware, consumer technology, e-commerce, gaming, autonomous vehicles, robotics, space and defense technology.
Jansen’s disputes work ranges from pre-litigation risk assessments and settlement negotiations to proceedings before the Trademark Trial and Appeal Board and cross-border trademark conflicts. He also handles domain name disputes, anti-counterfeiting matters and trademark issues involving internet and social media platforms.
His transactional practice includes trademark and domain name acquisitions, licensing arrangements and coexistence agreements. Those matters complement the firm’s existing trademark trial capabilities by supporting clients as they launch products, enter markets and acquire brand assets.
Jansen is the sixth intellectual property practitioner to join Orrick in 2026. Earlier additions included International Trade Commission trial lawyer Jordan Coyle, intellectual property trial lawyers Danielle Tully, Mike Powell and Josh Glucoft, and former U.S. Patent and Trademark Office Solicitor Farheena Rasheed.
Orrick said Jansen will help shape the continued development of its trademark practice. His arrival adds counseling and transaction experience alongside the firm’s litigation work, extending support for companies managing brand portfolios at different stages of growth.
KEY QUOTES:
“Clients at every stage look to us for advice on run-the-company issues as well as milestones, and trademark and brand counseling is key to both. Mark brings a valuable business-minded approach to innovators, helping them navigate critical brand decisions as they launch products, expand into new markets and build businesses for the long term. His experience in high-stakes trademark disputes is also a natural complement to our trademark trial team.”
Sheryl Garko, Trademark Trial Partner At Orrick
“Orrick pairs deep strength in trademark trials and litigation with a leading technology platform and a focus on innovation. I’m greatly looking forward to collaborating with this team to bring a technology-forward approach to how brand counsel is delivered, from a company’s first launch to its global portfolio.”
Mark Jansen, Partner At Orrick
