Justina Kahn Sessions

Ms. Sessions focuses her practice on commercial litigation, particularly intellectual property and antitrust matters. She has counseled individual clients and steered joint defense groups through complex patent disputes and high-stakes antitrust cases. 

She also maintains an active pro bono practice, recently obtaining a Ninth Circuit dismissal of an unprecedented lawsuit by an oil company seeking to silence environmental and Native Alaskan advocacy groups.  

Cases of Note

Netflix, Inc. v. Rovi: We defended our clients Netflix, Inc. and Roku Corporation in a U.S. International Trade Commission complaint filed by Rovi Corporation. The complaint accused our clients, along with Mitsubishi Electric Corp., LG Electronics Inc., and Vizio Inc., of infringing several patents related to interactive program guides. The complaint sought an order banning television and media-player makers from entering the U.S. By the time of the trial, the other defendants had settled and our clients faced four patents. We successfully defended our clients at trial, with the ALJ finding one of the patents invalid and none of the patents infringed, as well as no actionable importation or available remedy. The ITC confirmed there was no violation. Rovi then pursued the matter in District Court with three of the same patents used in the ITC investigation as well as two additional patents. We won summary judgment of invalidity under Alice on all five asserted patents, which the Federal Circuit affirmed summarily.

In re High-Tech Employee Antitrust Litigation: We helped Google reach a settlement in this antitrust class action brought on behalf of employees of Adobe, Apple, Google, Lucasfilm, and Pixar. The case stemmed from a United States DOJ antitrust action and a civil class action of 64,000 workers against the Silicon Valley companies for alleged "no cold call” agreements which restrained the recruitment of high-tech employees.

Former Employees v. Lucasfilm Ltd.: We advised Lucasfilm Ltd. in an investigation by the U.S. Department of Justice and then represented Lucasfilm in a series of antitrust class actions brought by former employees of Lucasfilm, Google, Apple and Pixar. Plaintiffs alleged unlawful agreements related to hiring and employee retention. Plaintiffs and Lucasfilm reached a preliminary settlement of plaintiffs’ claims in July 2013.

Guidance IP v. T-Mobile USA: We defended a wireless network provider in a patent-infringement suit filed in the Middle District of Florida relating to cellular-telephone geolocation. We obtained an early dismissal for our client after successfully moving to transfer the case to the Western District of Washington.

SoftView LLC v. Apple Inc. et al.: We are defending HTC in a lawsuit in the District of Delaware in which the plaintiff is asserting patent claims that purport to cover web-browsing technology on mobile devices.

Shell Gulf of Mexico, Inc., et al. v. Center for Biological Diversity, Inc., et al.: We successfully defended a group of Native Alaskan and environmental advocacy groups from Shell Oil's unprecedented lawsuit. Shell filed three lawsuits against our clients, seeking declaratory judgments that its oil-drilling permits were validly issued. We prevailed before the Ninth Circuit, which held that the district court lacked jurisdiction because Shell’s novel litigation tactic did not present an Article III case or controversy.
