Intellectual Property Litigation
Jackson Walker’s Intellectual Property Litigation group is a powerful and experienced team of IP attorneys and trial lawyers who combine proven successful trial strategies, skillful advocacy, and appropriate staffing. We approach every case with the recognition that it may very well be tried before a jury, and we prepare accordingly. We are no strangers to, and in fact relish, the courtroom.
We have enforced and defended all types of intellectual property matters in federal and state courts across the United States, from California to Delaware, and from Illinois to Texas. Among other jurisdictions, we have significant patent litigation experience in federal civil courts of the Eastern District of Texas, one of the country’s premier forums for patent disputes. We have successfully represented numerous clients, including Fortune 500 companies, in litigation:
- involving patents, trademarks, copyrights, trade dress, trade secrets, and domain names
- in arbitrations and alternative dispute forums
- in proceedings before the International Trade Commission, the 5th Circuit Court of Appeals, the Federal Circuit Court of Appeals, the Trademark Trial & Appeal Board, and the U.S. Supreme Court
- in proceedings conducted pursuant to ICANN’s Uniform Dispute Resolution Policy
Clients confronted with disputes involving their patents, trademarks, service marks, trade dress, trade secrets, copyrights, or other intellectual property assets can rely on our experienced litigators to aggressively represent their interests in matters extending from infringement claims to unfair competition to disputes over commercial licensing agreements. We assist our clients in all stages of intellectual property conflicts and resolution of the conflict, from pre-litigation analysis and communications through final verdict and, if necessary, appeal.
We regularly represent Fortune 500 companies in infringement lawsuits involving intellectual property. Our experience includes successful appeals to the Fifth Circuit Court of Appeals, the Federal Circuit Court of Appeals, the Trademark Trial & Appeal Board, and the U.S. Supreme Court. Our IP trial lawyers have also enforced and defended our clients’ intellectual property rights in arbitrations, alternative dispute forums, and proceedings before the International Trade Commission and the Patent Trial and Appeal Board.
We actively monitor the use of our clients’ intellectual property, and we can act quickly to enforce these various rights against infringers through the effective use of temporary restraining orders and preliminary injunctions. With vast experience in both prosecuting and defending litigation cases involving patents, trademarks, and copyrights, we succeed in recovering damages and quickly obtaining injunctions for our clients. Often times, our commercial litigation experience allows us to resolve licensing and contract disputes quickly and efficiently.
