Amgen was subsequently able to enforce its patent claims to their DNA coding for EPO against Genetics Institute (GI) to prevent GI from making rEPO in the U.S. See Amgen, Inc. v. Chugai Pharmaceutical Co., 927 F.2d 1200,18 U.S.P.Q.2d 1016 (Fed. Cir.), cert, denied, 502 U.S. 856 (1991). However, Chugai was free to make rEPO abroad and import it into the U.S. without infringing Amgen's patent on the DNA. After much delay, Amgen has recently been issued its patent covering the method for making EPO using the rDNA of its earlier patent. See U.S. Patent No. 5,441,868.

  14. This distinction is most easily understood through specific illustrations. For example, a biotechnology “method-of-making” claim might read, “A process of making protein X comprising culturing a microorganism transformed with a DNA encoding protein X under conditions such that the DNA is expressed and protein X is produced, and recovering protein X. Whereas as “method-of-using” claim might read, “A method of using a microorganism transformed with DNA encoding protein X for production of protein X.”
