Barrington has advised on the following selected significant matters:*

  • Obtained a preliminary injunction against the largest provider of FEMA-backed flood insurance for misappropriation of trade secrets and breach of contract in a case involving insurance technology (InsurTech) that expedites claims and prevents fraud.
  • Served as second-chair in a three-week trial on mobile advertisements and secured a jury verdict of fraudulent inducement and breach of contract against a major mobile game developer.
  • Represented a golf company in a copyright and patent infringement action involving golf club designs in the Northern District of California. Barrington negotiated a seven-figure settlement for the client.
  • Represented a provider of load balancing and cybersecurity services in a patent infringement action involving seven patents on computer networking technologies before in the Northern District of California. After a three-week trial, the jury returned a unanimous verdict and determined that the infringement on client’s patents was willful. After trial, the Court entered judgement in favor of client for $6.9 million and issued a permanent injunction against their competitor. Competitor’s patent and trade libel counterclaims were dismissed with prejudice before trial and they accepted client’s offer for judgement in the amount of $40,000 on their claim that client had violated a patent license.
  • Represented a provider of load balancing and cybersecurity services in a patent infringement action involving three patents on computer networking technologies in the Northern District of California. The case settled favorably after the court construed the claims and denied competitor’s summary judgment motions of non-infringement and invalidity.
  • Defended a data storage startup against allegations of trade secrets, breach of contract and trademark infringement case in the Northern District of California. Fifteen trade secrets on double data rate dual in-line memory module (DDR DIMM) technology were at issue, along with allegations for breach of contract and trademark infringement. Rather than awarding Plaintiff the $6.5 million in damages it sought, the jury awarded nominal damages of $2. The court subsequently lifted a ban on client’s sale of microchips used in data storage products from other providers, saying the injunction was not justified.
  • Defended a consumer electronics company in an ITC investigation brought by a competitor against defendant’s mobile phones and tablets. Obtained dismissal and non-infringement on eight of the ten asserted patents before the parties reached a worldwide settlement.
  • Represented a data storage startup in bringing three IPRs against a competitor. The PTAB instituted a review of all petitioned claims and found them invalid.
  • Represented a property technology (PropTech) in the Eastern District of Texas against multiple parties in a patent suit involving AI for assessing home values. Obtained favorable settlements from all but one of the defendants.
