IP Litigation

At Flaster Greenberg, we understand that intellectual property is often among a company’s most valuable assets. Our Intellectual Property Litigation team represents clients of all sizes — from emerging startups and growing mid-sized businesses to established national and international companies — in complex, high-stakes IP disputes.

We work strategically and efficiently to enforce our clients’ rights, defend against infringement claims, and resolve disputes in a manner aligned with their business objectives.

Patent Litigation

Patent disputes frequently involve sophisticated technology and significant commercial exposure. Flaster Greenberg represents clients in patent infringement actions, validity challenges, and licensing disputes in federal courts and administrative proceedings.

Our attorneys collaborate with technical experts to present clear, persuasive arguments while maintaining a focus on practical outcomes that protect innovation and market position.

They have substantial experience representing companies in patent litigation in U.S. patent jurisdictions including Federal District Courts (including district courts in Pennsylvania, Delaware, New Jersey, New York, Massachusetts, Texas, Virginia, California, Illinois, Florida, among others) and at the International Trade Commission. We have represented both defendants and plaintiffs in infringement actions, and understand the strategic advantages and potential risks faced by both sides. We have litigated cases involving software, electrical hardware, light emitting diodes, medical devices, pharmaceutical products, standards essential patents (SEPs), wireless technologies, industrial systems, and more. Flaster attorneys have also served as appeal counsel for clients before the Court of Appeals for the Federal Circuit.

We also have experience representing pharmaceutical companies in complex abbreviated new drug application (ANDA) cases both on behalf of pharmaceutical developers and new manufacturers. Given the interplay of federal drug regulations and U.S. patent law in these complex litigations, Flaster Greenberg is ideally suited to bring the knowledge and experience necessary to achieve a positive result in an efficient and responsive manner.

When it comes to patent infringement, Flaster Greenberg understands that infringement suits brought by non-practicing entities are different than most types of litigation and that these suits have to be managed accordingly. Our track record in successfully defending these types of suits in an economic way having nothing paid to those bringing such suits is unparalleled. We approach every patent case with a fresh perspective and develop unique and situation-specific strategies to gain the leverage necessary to obtain cost-effective outcomes.

Trademark Litigation

A company’s brand is critical to its success. We represent clients in trademark infringement, dilution, unfair competition, and false advertising matters. Our team appears in federal and state courts and before the Trademark Trial and Appeal Board (TTAB).

We act decisively to prevent consumer confusion, safeguard brand identity, and preserve competitive advantage.

Copyright Litigation

Copyright protection extends to software, digital content, music, film, visual art, and written works. Flaster Greenberg represents clients in disputes involving unauthorized use, reproduction, distribution, and performance of protected works.

We develop effective litigation strategies that protect creative assets while minimizing business disruption.

Trade Secret Litigation

Confidential and proprietary information can be as valuable as any registered intellectual property. We handle trade secret misappropriation cases involving proprietary technology, business methods, customer information, and other sensitive data.

When necessary, we move quickly to secure injunctive relief and pursue damages to protect our clients’ competitive position.

Strategic, Business-Focused Advocacy

Intellectual property disputes demand both legal precision and commercial insight. At Flaster Greenberg, we combine deep IP litigation experience with a practical understanding of our clients’ industries and business goals.

Whether enforcing rights or defending against claims, we are committed to protecting what our clients have built — efficiently, strategically, and effectively.
