I previously blogged about the Exelixis patent dispute. The Cabometyx patent trial occurred last week (May 16). A recent note on Seeking Alpha indicates that comments from the court during the trial suggests that Exelixis may lose on the ‘776 patent, but win on the ‘473 patent. (I was one of two patent experts on the Truist call referenced in the note.) If that happens, will Exelixis still be able to secure freedom from generics through 2030 based upon the ‘439, ‘440 and ‘015 patents asserted in its second lawsuit?

Exelixis is on the eve of trial against MSN over its prospective generic for Cabometyx. Yet, there are now two separate patent litigations between the companies related to Cabometyx.

A settlement conference is scheduled in the Hatch-Waxman patent case between Celgene and Dr. Reddy’s on January 10, 2019. Now that Bristol Meyers is at the table, will the parties be able to reach a settlement that couldn’t be reached before?
Read MoreYesterday, we blogged about why the Markman hearing was cancelled in Celgene’s Revlimid® patent case against Dr. Reddy’s. Some analysts suggested that this is a positive indication of a settlement approaching with Dr. Reddy’s and possibly with all generics. We weigh in.
Read MoreOn March 23, Celgene and Dr. Reddy’s informed the Court that they jointly have resolved the single pending claim construction dispute—namely, the construction of the word “crystalline” within the two asserted polymorph patents. What does this mean for the case?
Read MoreA number of generics are moving in on Celgene's Revlimid. Leading the pack is Dr. Reddy’s, and although Celgene has asserted numerous patents against Dr. Reddy’s proposed generic, a single issue has crystallized in advance of an upcoming Markman hearing that could make or break the case.
