    Illumina files trade-secrets lawsuit against Guardant Health

    Lawsuit filed

    Illumina filed a lawsuit against Guardant Health, alleging that Guardant's co-founders took confidential Illumina documents and that patents central to Guardant's cancer-detection work relied on that information. Guardant disputed Illumina's claims and said they had no merit.

    Source excerpt

    • Guardant has a sharply different version of events, arguing that Illumina’s claims have no merit
    • San Diego-based Illumina filed a lawsuit Wednesday in the U.S. District Court for the District of Delaware in which it says that Guardant’s co-founders, who are former Illumina employees, siphoned off tens of thousands of Illumina documents while creating their company.
    • The San Diego company wants the patents that Guardant filed turned over to them.
