Senator Warran recently asked what the Patent Office can do about patent thickets. Yet, the courts are in the unique position of having to contend with scores of patents asserted within a single suit. When a brand pharmaceutical company shows up with 20, 60 or 100 patents in a single suit, those challenges can be exacerbated by orders of magnitude. So, how have courts face this challenge?

While that defense is unique, and may be hard to prove on its face, the FDA appears to agree with Boehringer. Did AbbVie create a wrongful “patent thicket” around Humira®?

Roche currently faces pending biosimilar competition against Avastin® (bevacizumab), Roche’s biggest selling cancer drug, Herceptin® (trastuzmab), Roche’s breast-cancer drug, and Rituxan® (rituximab), Roche’s immunotherapy drug. All three drugs are involved in patent litigations. How long will these cases last? And how long can Roche keep the biosimilars out?

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.
