Patent Litigation

Trial-ready advocacy in complex patent litigation

Industry-leading companies call on Dechert to resolve their most complex patent litigation disputes. From the courtroom to the negotiating table, our patent litigators have an established record of obtaining favorable results for clients.

Our global team routinely represents high-profile clients in the most prominent patent litigation venues in the world. We have successfully tried cases in U.S. district courts, including patent litigation hotbeds in California, Delaware, New Jersey and Texas, as well as the International Trade Commission. We have also provided strategic guidance for cases in France, Germany, Japan, the Netherlands and the UK High Court, among others. Notably, on behalf of client SCA Hygiene Products in November 2016, the U.S. Supreme Court sided with SCA in a 7-1 decision on March 21, 2017 and reversed a 6-5 en banc decision of the Federal Circuit, overturning 100 years of precedent and concluding that laches cannot bar the award of legal damages in patent cases.  

Unlike most large firms – which are defense-oriented – we represent both plaintiffs and defendants, allowing us to provide clarity to clients on both sides of the table. Our lawyers regularly handle cases and complex international disputes where hundreds of millions or even billions of dollars are at stake. We also have a dedicated Hatch-Waxman litigation team with extensive experience in preparing for and litigating Abbreviated New Drug Application (ANDA) disputes.

Clients also depend on us to accomplish their objectives outside of the courtroom. Dechert has created and litigated many global patent enforcement campaigns for major international companies and has extensive experience running licensing programs to monetize portfolios.

We routinely secure licensing and settlement agreements that save our clients’ money, preserve their goodwill and deliver more long-term benefits than likely would have resulted from litigation.

We focus on our client’s needs and match our resources to the scope of the dispute. Clients count on Dechert to secure their interests in the most expeditious and cost-effective manner possible.
