  • In the Matter of Certain Portable Electronic Devices and Components Thereof (U.S. International Trade Commission): Stefani represented Google, BlackBerry, Lenovo, and Motorola and served as lead trial counsel for all respondents in this ITC investigation involving Google's Play Music application. Stefani successfully petitioned the ITC to utilize its 100-day program to issue an early determination on patent-eligible subject matter. The 100-day program had only been used twice before, and never to test patentability. Following development of an evidentiary record and a hearing, the ALJ issued an early initial determination finding all claims of the asserted patent invalid for failure to recite patent-eligible subject matter. The commission declined to review, and Creative has filed an appeal with the Federal Circuit.
  • In the Matter of Certain Digital Media Devices, Including Televisions, Blu-Ray Disc Players, Home Theater Systems, Tablets and Mobile Phones, Components Thereof and Associated Software (U.S. International Trade Commission): Stefani represented Google as lead trial counsel in this ITC investigation involving Google Play Music, Google Maps, Google Latitude, YouTube, and DIAL. The investigation raised novel issues relating to the ITC's jurisdiction, the requirement of infringement at the time of importation, and the assertion of indirect infringement in the ITC. Following a week-long trial in February 2014, on September 12, 2014, the ITC issued a determination in favor of Google, including finding non-infringement by all accused products across all asserted patents, invalidity of certain patents, and that complainant Black Hills Media, LLC lacks the required domestic industry. The investigation, outcome, and implications for future ITC cases are further described in The National Law Journal article titled "Important Victory for Google Inc." from September 22, 2014.
  • Fernando Morales v. Square, Inc. (W.D. Tex.): Stefani represented Square as lead counsel defending against claims of patent infringement. In December 2014, Stefani argued and won a motion to dismiss based upon invalidity resulting from the patent-in-suit failing to cover patent-eligible subject matter. Stefani also successfully represented Square in responding to Morales’s appeal to the Federal Circuit, with the Federal Circuit affirming the district court order.
  • Protegrity v. Square, Inc. (N.D. Cal.): Stefani is lead counsel representing Square in this patent suit relating to data encryption. Protegrity filed a motion to transfer with the Multi-District Litigation panel seeking transfer to the District of Connecticut. In January 2015, Stefani successfully argued on behalf of nine defendants, convincing the panel to centralize the cases in the Northern District of California. Wilson Sonsini Goodrich & Rosati also filed petitions for Covered Business Method patent review, and a successful motion to stay.
  • Digital Reg of Texas, LLC v. Adobe Sys. Inc., et al. (N.D. Cal.): Stefani was lead counsel defending Symantec in a patent case related to two patents purporting to cover a method of tracing users who access digital content. Defendants obtained transfer from the Eastern District of Texas to the Northern District of California. Symantec obtained a favorable ruling on summary judgment, after which the case settled.
  • E-Contact Technologies, LLC v. Google, Inc. (E.D. Tex.): Stefani defended Google in a patent case brought by E-Contact in the Eastern District of Texas relating to an electronic computer diary patent and accusing Gmail's auto-complete functionality of infringement. Upon construing the claims, the court found the asserted patent invalid for indefiniteness.
  • Check Point Software Techs., Inc. v. SRI Int'l, Inc. (N.D. Cal.): Stefani was lead counsel for Check Point in this declaratory judgment action seeking a declaration of non-infringement and invalidity of patents relating to intrusion-detection systems. The case presented unique issues relating to invalidity, non-infringement, and damages. Following a victory at claim construction, the parties agreed to resolve what remained of the case in binding arbitration. Stefani was lead counsel for Check Point at the arbitration, and the arbitrator found in favor of Check Point.
  • In the Matter of Certain Ground Fault Circuit Interrupters and Products Containing Same (U.S. International Trade Commission): Stefani represented Leviton in an ITC investigation involving ground fault circuit interrupters. Leviton obtained a rare general exclusion order against GFCI products manufactured in Asia and imported into the United States through multiple channels. Stefani also worked with U.S. Customs and Border Protection to enforce the exclusion order.
  • Government Technology Solutions v. Fortinet, Inc. (Judicial Arbitration and Mediation Services, Arbitration): Stefani defended Fortinet in this arbitration brought by a former partner alleging Fortinet improperly terminated the partnership and claiming damages. She successfully tried the case and obtained a judgment in Fortinet's favor on every issue, entitling Fortinet to its attorneys' fees.
