Intellectual Property

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


The McConnell Valdés Intellectual Property team is among the most highly respected and accomplished in Puerto Rico. Top-ranked by Chambers and Partners Latin America for “extremely responsive and 100% knowledgeable” counsel, the team is deeply experienced across the IP ambit.

We are often called upon to help draft IP laws, regulations and amendments by government officials. McConnell Valdés was invited to help draft the new Trademarks Act of Puerto Rico and the Consumer Defense Code. When the Department of Consumer Affairs (DACO) Regulation on Misleading Practices and Advertisements was amended, it incorporated a number of firm proposals and amendments. One of our attorneys helped draft the Right of Publicity bill, the Trade Secrets bill, and the Moral Rights bill, signed into law between 2011 and 2012.

Recognizing intellectual property as an invaluable corporate asset, we are dedicated to helping clients select and obtain the best protection for their trademarks, service marks, patents, and copyrights under both United States and Puerto Rico law. In addition, we regularly coordinate the protection and enforcement of our clients’ intellectual property in international jurisdictions, by working closely with qualified attorneys in other countries.

Comprised of lawyers from both the corporate and litigation practices, team members have achieved significant victories for clients facing the full scope of IP challenges, from trade dress and cross-border copyright infringement cases to cases involving the sale of counterfeit items and false advertising claims. Our seasoned litigators have achieved wins for our clients in federal, state and local courts, as well as before the Puerto Rico trademarks, commercial names, and moral rights registration agencies.

We successfully prosecute and vigorously defend our clients’ copyrights and innovations before the Copyright Office and the United States Patent and Trademark Office (USPTO). Our team’s representation also extends to defending clients against claims presented by the Business Software Alliance (BSA), helping clients on an array of related issues by:

  • Formulating responses to BSA claims.
  • Advising clients on software audits.
  • Establishing and crafting corporate software use policies and internal controls to prevent unauthorized software copies.
  • Preparing memoranda to employees regarding the unlicensed duplication or use of software.
  • Preparing corporate–employee agreements.

A number of our “excellent,” “extremely helpful” and “focused” team members, ranked among Puerto Rico’s Leading Lawyers by Chambers and Partners Latin America and selected by their peers for inclusion in The Best Lawyers in Puerto Rico 2016 and 2017, are active members of the International Trademark Association (INTA) and participate in many of INTA's regional committees.
