Teva, Israel’s generic drug giant, manufactures a generic version of Oxycontin, a pain killer developed and patented by Purdue. back in June, the US Court ruled in favor of defendant Endo, that Purdue’s patents for Oxycontin were worthless, due to innacurate statements made to the USPTO during their prosecution, and granted Endo a six month grace period to market the drug.
In December 2005, after the grace period ended, Teva started to market their generic version of the drug. The appeals court has now reopened the debate on the validity of the patents, and Teva risks being sued for willful infringement, which carries a penalty of 3 times damages.
Used Teva and Endo generic oxycontin only the Teva brand generic worked. The endo product did not work. Suggest you test Endo generic version of Oxycontin for analysis, again, they do not work while the Teva do work!
