Recognized in Intellectual Property Litigation by BTI Litigation Outlook and Best Lawyers®, Polsinelli’s IP litigators combine national trial experience and technical depth to identify, protect and defend business-critical IP rights.

As a robust, national practice, Polsinelli can staff any sized case based on client needs and goals. We work closely with clients to understand the legal, technical and commercial considerations behind each dispute, developing litigation strategies tailored to what matters most.

Whether a matter calls for litigation before the District Court, the Patent Trial and Appeal Board (PTAB) or Trademark Trial and Appeals Board (TTAB), or action before the International Trade Commission (ITC), our litigators help clients determine the right forum, sequencing and strategy for their dispute.

Our litigation experience spans a wide range of technologies and industries, including life sciences, pharmaceuticals, medical devices, software, electronics, consumer products, manufacturing and other innovation-driven sectors. Whether protecting emerging technologies or defending established portfolios, we tailor our approach to the technical, legal and commercial considerations involved.

Coordinated Strategies Across Key IP Forums

• Federal courts: We litigate IP disputes in federal courts nationwide, including active patent venues such as the District of Delaware, Eastern District of Texas, Northern District of California and Northern District of Illinois. Our attorneys also handle appellate matters before the Federal Circuit Court of Appeals and other federal circuits across the country.
• Hatch-Waxman & Biologics: Our attorneys have decades of collective experience in the highly specialized areas of Paragraph IV litigation under the Hatch-Waxman Act and biologics litigation under the Biologics Price Competition and Innovation Act (BPCIA). We represent clients in key venues and advise on the legal and business considerations that shape pharmaceutical patent disputes.
• USPTO post-grant proceedings: We represent patent owners and challengers in inter partes or post-grant reviews, ex parte reexaminations and related proceedings before the PTAB, often in parallel with district court or ITC litigation. Our team aligns validity strategy with the broader case, working closely with patent prosecutors and technical professionals.
• ITC Section 337 investigations: We handle Section 337 investigations involving patents, trademarks, copyrights, trade secrets and unfair competition claims tied to imported goods. With a former ITC Commissioner and prior agency attorneys on our team, we help clients navigate expedited proceedings, exclusion order remedies and related customs enforcement issues.
