To protect our clients’ valuable inventions, we represent plaintiffs and defendants in patent disputes in federal courts throughout the United States. Our lawyers are well-versed in the broad range of technologies and industries involved in these cases, including electronics, semiconductors, software, telecommunications, the internet, FDA-approved drugs and medical devices, chemical engineering and materials science, and media and entertainment. Because most of these cases require court construction of numerous patent claim types and claim terms, we have extensive experience in handling claim construction issues. In addition, we routinely handle appeals before the Federal Circuit.

Our trial attorneys also help clients enforce their patents and patent portfolios through private licensing arrangements, which are how patent rights typically achieve resolution. Before initiating such licensing programs, we conduct substantial patent and claim analysis and engage potential licensees in face-to-face meetings, clarifying the technical and legal issues that inform a company’s choice between litigation and licensing.

While we do not prepare or prosecute patent applications before the U.S. Patent and Trademark Office (USPTO), many of our lawyers are registered to practice before the USPTO. This prior experience gives us first-hand perspective on the issues faced by patent prosecution lawyers and patent examiners. It also enables us to advise clients and their patent prosecution counsel on any post-issuance matters—such as filing and opposing requests for reexamination or reissue—and enhances our understanding of the possible effects of such procedures on pending or proposed litigation.


Representative Matters

Our attorneys’ patent litigation experience includes the following matters, among others:

  • Nokia Technologies. Represented Nokia in several patent infringement actions against Apple Inc., alleging infringement of several Nokia patents directed to video coding and other technologies used in numerous popular Apple products. In May 2017, the companies reached a confidential settlement to end the global dispute that spanned across courts in United States (Texas), Europe, China, and Japan, in addition to the International Trade Commission.  As part of the agreement, Apple reportedly agreed to pay Nokia a one-time case settlement of approximately $2 billion dollars with additional revenues, including a multiyear patent license.
  • Ericsson. Secured a $75 million verdict against TCL Communications Technology Holdings Ltd. in a patent infringement suit in the Eastern District of Texas, concerning a system for controlling access to resources in a platform in a mobile terminal. Months later, a magistrate judge reconsidered his order for a new trial on damages and reinstated the original $75 million verdict and awarded Ericsson an additional $35 million, which included enhanced damages against TCL Communications due to wilful infringement. The verdict was recognized as a 2018 Top 100 Verdict by VerdictSearch and The National Law Journal.
  • WiLAN. Secured a $145 million jury verdict on behalf of WiLAN, Inc against Apple in a patent infringement suit concerning infringement of two WiLAN patents that cover voice over LTE ("VoLTE") wireless communication technology used in many Apple products, including the iPhone 6, iPhone 6 Plus, iPhone SE, iPhone 6s, iPhone 6s Plus, iPhone 7, and iPhone 7 Plus.
  • Rovi Corp. Secured a victory for TiVo’s Rovi Corp. against Comcast Corp. in the International Trade Commission (ITC). The ITC issued a final ruling affirming, in large part, the Initial Determination of Administrative Law Judge David P. Shaw regarding two of Rovi's patents relating to set-top boxes. The ITC found that Comcast violated Section 337, which involves imports and issued both an exclusion order and a cease and desist order prohibiting Comcast from importing into the U.S., or otherwise distributing after importation, any set-top box that infringes Rovi’s patents.
  • Ericsson. Representation of Ericsson Inc. in patent infringement actions against Apple concerning 41 of Ericsson’s standard essential and implementation patents.

The matter has since settled on confidential terms.
