Chinese companys appeal court's decision on Pfizer's VIAGRA patent (Ten Chinese companys, who are among the 12 companys requesting invalidation of Pfizer's VIAGRA patent, appeal to the Higher People's Court of Beijing a lower court's decision supporting Pfizer's VIAGRA patent. Although the decision of the lower court, the Second Intermediate People's Court of Beijing, is against an earlier decision by the Patent Reexamination Committee of SIPO invalidating Pfizer's VIAGRA patent, the Reexamination Committee itself, however, does not appeal the lower court's decision. The ten Chinese companys made the appeal as the third party of the case of Pfizer vs the Reexamination Committee in the lower court. The remaining two companys among the 12 companys requesting the invalidation, however, also does not appeal).
