Guardant Health appeals Delaware court judgment in TwinStrand patent dispute
GH•Royalty order and product impact
The royalty order covers products that existed at the 2023 trial; current Guardant Reveal and Shield are excluded from potential royalties.
Design changes to Guardant360 have been validated to avoid the impact of potential ongoing royalties.
