- Represented Cribl, developer of big data processing engine for information technology and security operations, in a federal case against Splunk alleging copyright infringement and breach of contract claims. Jocelyn conducted the cross-examination of Splunk’s damages expert, who opined that Splunk was entitled to $160 million in damages at trial. After both parties presented their cases, the court found that certain uses of Splunk’s software by Cribl fell under fair use. Although the jury found that Cribl separately infringed Splunk’s copyright and breached a contract, the jury awarded just $1.
- Represented Natera in patent infringement litigation involving transplant monitoring tests against competitor CareDx. After a week-long trial, the jury awarded Natera nearly $100 million in lost profits and past royalties.
- Represented Google in its defense against patent infringement allegations brought by Sonos against a wide array of Google’s smartphone and audio devices. Sonos initially demanded over $3 billion in damages for its six asserted patents, four of which were dismissed on summary judgment or voluntarily dismissed by Sonos. During trial, Sonos’ damages theory seeking $90 million in past royalties for the remaining two patents was rejected by the Court based on Google’s Daubert challenge, and following trial, the Court found that these patents were unenforceable under the doctrine of prosecution laches based on Sonos’ unreasonable delay and lack of written description in its original patent filings.
