Bio-Rad Laboratories, Inc. v. United States International Trade Commission, No. 20-1475 (Fed. Cir. 2021)Annotate this Case
Bio-Rad’s patents relate to the generation of microscopic droplets, contiguous fluid that is encapsulated within a different fluid, by using a microfluidic chip. Typically, the inner fluid is water-based, while the outer fluid is oil. The patents arise out of research conducted by inventors at QuantaLife. In 2011, Bio-Rad purchased QuantaLife, acquiring QuantaLife’s patent rights. The inventors became employees of Bio-Rad and executed assignments of their rights to applications that later issued as the 664, 682, and 635 patents. Soon after Bio-Rad acquired QuantaLife, three inventors left Bio-Rad to start 10X, which has developed technology and products in the field of microfluidics, with the goal of achieving DNA and RNA sequencing at the single-cell level.
Bio-Rad alleged that 10X violated the Tariff Act, 19 U.S.C. 1337, by importing into the U.S. certain microfluidic chips. The Trade Commission concluded that 10X did not infringe the 664 patent by importing its “Chip GB” but infringed the 664, 682, and 635 patents by importing its “GEM Chips.” The Federal Circuit affirmed. The construction of the term “droplet generation region” is consistent with the intrinsic evidence; substantial evidence established that the use of 10X’s GEM chips directly infringes the asserted claims. Bio-Rad proved the elements of induced and contributory infringement of the 682 and 635 patents with respect to the GEM Chips.
