Armstrong Teasdale’s Intellectual Property (IP) Litigation team is led by trial lawyers with a proven track record in patent, trademark, copyright, and trade secret lawsuits and related antitrust and commercial litigation. Our lawyers combine their deep experience in the law with their knowledge of evolving technologies to defend our clients’ interests and advance their business objectives.

Our U.S. IP litigators have significant experience managing disputes in tribunals around the country, including federal district and appellate courts, the Court of Federal Claims, the Patent Trial and Appeal Board (PTAB) and the Trademark Trial and Appeal Board (TTAB). Our U.K. team has extensive experience handling litigation at all levels within the English courts, as well as managing multijurisdiction disputes and, where necessary, working with IP practitioners in other jurisdictions to protect and enforce our clients' valuable intellectual property rights, including through interim injunctive relief and enforcement of arbitral awards and court judgments.

Patent Litigation

Armstrong Teasdale’s patent litigation team has won defense and plaintiffs’ verdicts in multimillion-dollar cases in some of the country’s toughest patent venues, including in Delaware, Texas, Virginia and California. For every case, we create dynamic and efficient teams of skilled trial lawyers, technically trained patent lawyers and other IP professionals. Our team of IP professionals includes numerous patent lawyers and agents registered to practice before the USPTO, many of whom have industry experience and advanced degrees, including Ph.D.s, in fields such as electrical, computer, mechanical, aerospace, chemical, biochemical and biotechnical engineering. Our IP litigation team harnesses this valuable experience in executing winning strategies, yielding successful outcomes for clients in matters involving such disparate technologies as night vision goggles, industrial chemicals, nutritional supplements, retinal surgery devices, asphalt additives, computer memory devices, LEDs, silicon wafers, carbon capture technology, earth-moving machinery, electronic voting machines, consumer products, telemedicine technology and computer middleware.

This vast experience provides our IP litigators with the insight and tools needed to win IP disputes, regardless of size and complexity. We assess the potential risks and rewards of fighting IP lawsuits and provide creative strategies and solutions to our clients across a wide range of industries. These creative solutions include strategic use of cost-effective post-grant proceedings at the PTAB. Armstrong Teasdale has a robust PTAB practice led by established patent lawyers with extensive experience leveraging these proceedings—as an alternative to, or in parallel with, district court litigation—to achieve our clients’ goals. At every stage of a case, we remain singularly focused on achieving our clients’ objectives.

Trademark, Trade Dress and Unfair Competition Litigation/Passing Off

Our trademark litigation team actively defends the integrity of our clients’ brand and product identities. Our lawyers monitor and enforce our clients’ trademark rights both online and around the world. When disputes arise, we have successfully protected our clients’ trademark and trade dress rights through infringement actions in federal court and cancellation and opposition proceedings at the Trademark Trial and Appeal Board as well as the U.K. Intellectual Property Office. In addition, our U.K. lawyers act to protect clients’ image/personality rights, as well as to pursue passing off claims. We strategize and coordinate investigations and enforcement actions against counterfeiters in the U.S., China and around the globe.

Copyright Litigation

Our IP litigators work closely with copyright lawyers to ensure that clients’ rights are broadly protected and enforced. We have successfully addressed numerous instances of misuse of copyrighted works in a wide range of media and industries. We enforce copyrights and defend against claims of infringement on behalf of clients online and elsewhere, including enforcement through federal litigation, Digital Millennium Copyright Act demands, take-down complaints for online infringement and more.

Trade Secret Litigation

Our noncompete and trade secrets lawyers have won or avoided many temporary restraining orders (TROs) and many preliminary injunctions in numerous state and federal courts for clients in over 100 industries. In addition, they have written award-winning articles on noncompete and trade secret litigation that have been cited by the courts. Our lawyers are skilled at quickly counseling clients and moving swiftly to obtain immediate injunctive relief through temporary restraining orders and preliminary injunctions, as well as permanent injunctions. Our lawyers also work with data innovation, security and privacy professionals to protect proprietary information before data breaches occur, as well as to formulate responses following a breach.
