In Re Quest Diagnostics, Inc., No. 21-193 (Fed. Cir. 2021)
Annotate this Case
Ravgen filed suit in the federal district court in Waco, Texas, accusing Quest’s QNatal Advanced test of infringing patents relating to non-invasive tests for prenatal genetic disorders. Quest moved to transfer the case (28 U.S.C. 1404(a)), arguing that the Central District of California was a more convenient forum; its knowledgeable employees work in that district and third-party witnesses reside in the district. Although Quest maintains patient service centers across the country—including in the Western District of Texas—Quest designed, developed, and continues to perform QNatal Advanced testing only in the Central District of California. Quest argued that Ravgen, headquartered in Maryland, has no meaningful connections to the Western District of Texas. Ravgen noted that it had filed three related complaints in the Western District of Texas, alleging infringement of the same patents. After analyzing the public and private interest factors that govern transfer determinations, the district court denied Quest’s motion.
The Federal Circuit directed the district court to transfer the case. When there are numerous witnesses in the transferee venue and the only other witnesses are far outside the plaintiff’s chosen forum, the witness-convenience factor favors transfer. The court erroneously discounted documents located in California that relate to the development, validation, testing, and performance of the accused product and in weighing court congestion as strongly against transfer.
