Celgene win leaves Bass even in PTAB institution game

The PTAB has denied institution of a Coalition for Affordable Drugs inter partes review petition challenging a Celgene patent. This leaves Kyle Bass with a 50% institution success rate in the 14 petitions the Board has decided thus far

The Patent Trial and Appeal Board today released its 14th decision on a Coalition for Affordable Drugs inter partes review, denying a petition challenging a Celgene patent for the Pomalyst myeloma cancer treatment.

It is Celgene’s first good news in its disputes with hedge fund manager Kyle Bass at the PTAB, with trials instituted for four other IPRs challenging its patents. The Board had also rejected its motion to sanction Bass.

The decision also leaves Bass even in terms of institutions and denials so far, with seven petitions instituted (one of which was granted in part) and seven denied. The Coalition for Affordable Drugs, which was set up by Bass and Erich Spangenberg, has filed 33 petitions in total.

The Board should also give a decision this month on an IPR filed on May 21 challenging US Patent 6,926,907, which is owned by Pozen and covers the Vimovo treatment. Horizon Pharma bought the US rights to the stomach ulcer treatment in 2013.

In its latest institution decision, the PTAB said the information presented in the petition and accompanying evidence did not establish a reasonable likelihood that the Coalition for Affordable Drugs would prevail in showing the unpatentability of the challenged claims.

The institution decisions the PTAB has given on the Coalition's petitions so far are below.
