And just like that, it’s over. Boehringer Ingelheim has thrown in the towel in its patent fight with AbbVie over Boehringer’s proposed biosimliar for Humira®. Boehringer was a lone hold-out among a long line of proposed biosimilars for AbbVie’s blockbuster. Boehringer’s distinction was that it had raised a unique defense, namely, arguing that AbbVie had built an unfair “patent thicket” around Humira® that was unenforceable. We previously blogged about Boehringer’s “unclean hands” defense here and here and here. Now that Boehringer has settled, what are the larger lessons for future biosimilar patent fights?
Read MoreThe Court in AbbVie’s patent fight over Humira with Boehringer Ingelheim said that it “seems clear enough” that AbbVie had a patenting program designed to mitigate biosimilar entry for Humira®. Though AbbVie clearly danced around ways to avoid producing much of its behind-the-scenes strategizing for building a patent estate sizeable enough to practically coerce settlements, the Court has ordered AbbVie to pull up its skirt.

Read MoreAbbVie ($ABBV) has commenced its latest litigation in its campaign to keep biosimilars for Humira® at bay. On August 10, AbbVie brought suit against Sandoz ($NVS) asserting that two of AbbVie’s patents will be infringed by Sandoz’s proposed biosimilar. Sandoz is the fifth biosimilar to throw its hat in the ring. Does this increase the odds of the US market seeing a biosimilar for Humira® before 2023?
Read MoreThe biosimilar statute, Biologics Price Competition and Innovation Act (BPCIA, was passed in 2010. Since then, drug companies have been filing biosimilar applications with FDA. And even though, FDA has approved only nine biosimilar drugs today, an interesting trend may be emerging: biosimilars may be more willing to launch at-risk than small-molecule generics.
