The difficulty in resolving multiple rounds of patent litigation can foster a willingness on the part of both parties to settle their differences and go on their respective ways, which seems to be the end result of litigation between San Diego-based Illumina Inc., and subsidiaries of BGI Group of Shenzen, China. While Illumina is on the hook for a $325 million payout in this agreement, the company will receive a license to practice some of BGI’s affiliate’s patents, but the handshake also forecloses any further litigation over the disputed patents for three years.
