Scientific Plastic Prods., Inc. v. Biotage AB, No. 13-1219 (Fed. Cir. 2014)
Annotate this CaseSPP owns three patents that relate to a resealable cartridge for low pressure liquid chromatography (LPLC). The 061 patent claims a method of performing LPLC using the cartridge, the 571 patent claims the cartridge, and the 327 patent claims a modified cartridge. After SPP filed suit against Biotage for patent infringement, Biotage requested inter partes reexamination of the three patents. The district court stayed the infringement litigation. The patent examiner rejected all claims of the three patents on the ground of obviousness, and the Patent Trial and Appeal Board affirmed the rejections and cancelled all claims. The Federal Circuit affirmed, upholding a finding that it would have been obvious for a person of ordinary skill in the field of the invention to modify a certain chromatography cartridge with a certain resealable threaded cap.
