Sanofi has already slapped Eli Lilly with one patent infringement lawsuit over its Lantus copy, effectively keeping the competitor off the market until at least mid-2016. But now, it's filed another, wider suit.
Teva just won't give up on delaying generic Copaxone. Its latest tactic: filing a citizen petition with the FDA to once again push for full-scale, placebo-controlled clinical trials for all copies of its multiple sclerosis med.

Weak Qsymia sales have been the all-important issue for Vivus since the highly anticipated obesity therapy stumbled out of the gate, inspiring an all-out proxy war that wreaked havoc on the company's boardroom.

Pfizer has settled its patent fight with Teva Pharmaceutical Industries and Actavis, allowing both generics companies to launch Celebrex copies in December at the latest. That's 6 months after the 2014 patent expiration, but 12 months ahead of the reissued 2015 method patent.
Last week, generics makers asked the Supreme Court to let them launch their copies of Teva's Copaxone while it hears the Israeli company's appeal over the drug's patents.
