Intellectual Property

Our Intellectual Property Litigation attorneys are among the most highly respected and accomplished in Puerto Rico

The McConnell Valdés Intellectual Property Practice Team is widely regarded as one of the most respected and accomplished in Puerto Rico.

Government officials frequently rely on our expertise when drafting intellectual property laws, regulations, and amendments. McConnell Valdés was invited to contribute to the drafting of the new Puerto Rico Trademarks Act and the Consumer Defense Code. Amendments to DACO’s Regulation on Misleading Practices and Advertisements incorporated several of our firm’s proposals. In addition, one of our attorneys played a key role in drafting the Right of Publicity, Trade Secrets, and Moral Rights bills, all enacted between 2011 and 2012.

Recognizing that intellectual property is a critical corporate asset, we are committed to helping clients secure optimal protection for their trademarks, service marks, patents, and copyrights under both U.S. and Puerto Rico law. We also regularly coordinate international IP protection and enforcement through close collaboration with trusted attorneys around the globe.

Our team, composed of lawyers from both corporate and litigation practices, has achieved significant victories across the full spectrum of IP challenges—from trade dress disputes and cross‑border copyright infringement actions to cases involving counterfeit goods and false advertising. Our experienced litigators have prevailed for clients in federal, state, and local courts, as well as before Puerto Rico’s trademark, trade name, and moral rights registration agencies.

We also effectively prosecute—and vigorously defend—clients' IP rights before the U.S. Copyright Office and the United States Patent and Trademark Office (USPTO).

Our representation extends to defending clients in matters involving the Business Software Alliance (BSA) and assisting with a wide array of related compliance and enforcement issues including:

Top-ranked by Legal 500, Chambers and Partners and the peer-based The Best Lawyers in Puerto Rico guide, our attorneys are active members of the International Trademark Association (INTA) and participate in many of INTA's regional committees.
