Trademark Infringement Lawyers

As the speed and availability of information, marketing, and commerce increases, so does the potential for trademark infringement and abuse. Platforms that empower legitimate actors to sell their own products also empower counterfeiters and other bad actors to infringe on your brand and chip away at your sales and reputation. Our team of experienced trademark infringement lawyers helps protect against the constantly-evolving techniques of infringers by fighting and winning cases for our clients.

Internet trademark infringement can take many forms.

Litigating trademark infringement claims for internet-related activity has been at the core of our law practice for more than a decade. Our trademark infringement lawyers have set precedent, proposed new infringement theories, and handled trademark claims involving venues such as the Amazon Marketplace and app stores.

We can help protect your trademarks against a wide array of infringement. Whether it’s counterfeiting, infringement in paid search ads, search engine spam, or cybersquatting, we can take rapid, decisive action on your behalf. Contact Us to learn more.

While counterfeiting and cybersquatting may be the most common forms of infringement of trademarks, they are not the only forms. Companies seeking an unfair advantage may incorporate the trademarks of their competitors into a wide array of online materials. The trademark infringement lawyers at Kronenberger Rosenfeld can help you distinguish between fair use of your trademarks and actionable infringement and can bring a quick halt to the latter.

As in our internet copyright enforcement practice, our knowledge of web technologies, and our experience negotiating and litigating trademark disputes give us an upper hand in representing our clients. Whether your trademark appears in a competitor's web pages, metadata, or pay-per-click ad text and keywords, we can help you understand the scope of the problem, and the most cost-effective solution. We do so quickly before the issue threatens your customer relations or the well-being of your business.

We can also help you track down occasional, evasive, or anonymous infringers and help develop policies and programs designed to weed out and prevent further infringement.

Kronenberger Rosenfeld's seasoned trademark infringement lawyers have experience litigating unique & challenging cases, and we are ready to discuss any infringement issues you may have. Please use our easy online case submission form or contact us via phone at (415) 955-1155, ext. 120.
