上皮成長因子受容体
Yeda Research and Development, a company set up to commercialize and market the products of research at the Weizmann Institute of Science in Israel, challenged the Aventis-owned patent, licensed by Imclone, for the use of anti-Epidermal growth factor receptor antibodies in combination with chemotherapy, to slow the growth of certain tumors. This is the so-called '866' patent, which was filed in 1989 by Rhone-Poulenc-Rorer, issued in 2001, and on which Joseph Schlessinger was listed as first-named inventor.
