We previously blogged about Teva’s ($TEVA) petition for post-grant review (PGR) of Corcept Therapeutics’ ($CORT) ‘214 patent.  Since then, on November 20, 2019, the PTAB granted institution of Teva’s petition.  The proceeding will now be litigated for another year before a final decision.  On a recent earnings call, Corcept stated that it believes the standard for institution is “pretty low,” and not necessarily dispositive that Teva will prevail.  Now that we have the institution decision, what can we glean from it, and how likely is that Corcept’s patent survives?
