Williams & Connolly’s reputation for handling “bet-the-company” civil litigation at the trial and appellate levels applies equally to the firm’s thriving Intellectual Property Practice. Major corporations including Google, Dropbox, Samsung, Intel, Pfizer, Eli Lilly, Alcon, Roche/Genentech, Bayer, AstraZeneca/MedImmune, and many others place their trust in Williams & Connolly litigators to handle major intellectual property matters, particularly in patent litigation and related licensing disputes.

About 50 Williams & Connolly attorneys devote a substantial portion of their practice to patent cases, including fifteen former clerks of the United States Court of Appeals for the Federal Circuit. Many of our lawyers practicing in this area have science degrees, and fifteen have been admitted to practice before the United States Patent and Trademark Office.

A major part of Williams & Connolly’s patent litigation practice is representing pharmaceutical companies in Hatch-Waxman pharmaceutical patent litigation.

Williams & Connolly has handled over 100 IPR proceedings, including numerous concurrent with district court proceedings in Hatch-Waxman cases.

Pharmaceuticals: A major part of Williams & Connolly’s patent litigation practice is representing brand-name pharmaceutical companies in Hatch-Waxman pharmaceutical patent litigation against generic competitors seeking to sell generic versions of the brand companies’ drugs. Over the years, the firm achieved significant successes for many companies involving a diverse array of highly successful drugs, prevailing numerous times at trial and in the Federal Circuit.

Biotechnology: The firm also handles significant patent, licensing, and trade secret disputes in biotechnology for Roche/Genentech, AstraZeneca/MedImmune, and Pfizer, among others, in courts and arbitral forums throughout the world, including before the United States Supreme Court in the landmark MedImmune case, which addressed a licensee’s ability to challenge a patent while still paying royalties.
