Notable Representations
- Vaporstream, Inc. v. Snap Inc. Represented Vaporstream in the first patent infringement lawsuit against Snap Inc. d/b/a Snapchat, filed in the Central District of California. Ms. Xi spearheaded pre-suit due diligence efforts on Snap’s ephemeral messaging app and most recently drafted the (successful) opposition to the § 101 motion for summary judgment filed by Snap. Ms. Xi also devised claim construction positions on behalf of Vaporstream, arguing and obtaining a very favorable Markman ruling. The case is currently set for a jury trial in August 2018.
- Rockstar Consortium Inc. v. Google Inc. Represented Rockstar Consortium (a joint venture comprised of Apple, Ericsson, Sony, and Blackberry) in a patent infringement suit against Google in the Eastern District of Texas involving patents related to search advertising. The case was one of the largest patent cases in history because Google had previously placed a bid of $4.4 billion for the Nortel patent portfolio, a subset of which was asserted in this case by Rockstar against Google. Ms. Xi handled several phases of the litigation: devising favorable Markman positions, winning key discovery motions, arguing the Markman hearing, and preparing and defending key witnesses. The settlement of the hard-fought case resulted in a $900 million sale of the patent portfolio.
- NRG Renew LLC v. SunPower Corporation, Systems. Defended SunPower in this complex litigation matter involving multi-hundred-million dollar indemnification and breach of contract claims arising from the financing and construction of one of the world’s largest solar power plants, California Solar Valley Ranch in San Luis Obispo County. At the case’s inception, Ms. Xi tackled thorny issues involving tax and administrative law to craft, argue, and win two demurrers brought by SunPower in the Superior Court for the County of Contra Costa. Thereafter, Ms. Xi spearheaded every phase of the case, from fact discovery to expert analysis to summary judgment. Ms. Xi obtained a favorable settlement for SunPower after prevailing on a motion for summary adjudication.
- Personalized Media Communications, LLC Cases. Scored numerous victories for Personalized Media Communications (PMC), owner of one of the world’s most valuable patent portfolios (according to an Ocean Tomo study). In a series of cases against Vizio, Samsung, and Funai asserting standard-essential digital television signal processing patents, Ms. Xi has authored oppositions to and won two § 101 motions to dismiss, argued for and obtained favorable Markman rulings, and taken and defended key depositions. In January 2016, Ms. Xi won a motion to dismiss for lack of personal jurisdiction on behalf of PMC in a declaratory judgment action filed by Funai Electric Co. in the District of Delaware. Within days of winning the motion, Ms. Xi filed a lawsuit on behalf of PMC against Funai in the Eastern District of Texas and litigated the case until settlement. The trio of cases against Vizio, Samsung, and Funai settled on highly favorable terms, with all three defendants becoming proud licensees of PMC. Ms. Xi currently represents PMC in patent infringement cases against Chinese TV manufacturers Hisense, TCL, and Tongfang filed in the Eastern District of Texas. The cases are set for trial in early 2019.
- Sentius International, LLC v. Microsoft Corp. Represented Sentius against Microsoft in an infringement suit involving automated database technology. Ms. Xi drafted successful oppositions to summary judgment and Daubert motions. The case settled on highly favorable terms within 24 hours of those motions being denied.
