AbbVie’s Pharmacyclics recently sued BeiGene for patent infringement. Both companies distribute Bruton’s tyrosine kinase (BTK) inhibitors for treatment of, among other indications, chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL). Pharmacyclics sells Imbruvica® and BeiGene sells Brukinsa®. Will Pharmacyclics prevail, and if so, what will it gain?

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.
