Trademarks are among the most valuable intellectual property assets a company owns. LPHS helps clients protect their brands, product names, logos, slogans and trade dress. We represent clients with trademark portfolios in the United States and throughout the world in diverse industries, including software development, technology, manufacturing, professional services, agriculture, hospitality, cosmetics and health care.

We represent both plaintiffs and defendants, and our lawyers have decades of experience litigating large and small trademark cases before federal and state courts throughout the United States. We have experience litigating all types of trademark rights, including trademarks, service marks, trade dress, product configurations, trade names, and even part numbers for manufacturing companies.

But we are, at the core, a trial firm. Our case preparation focuses on what matters: winning a jury trial. Our opponents respect us because they know we prepare to take every case to trial. And our reputation in the courtroom enhances our ability to achieve our clients’ business objectives.
