I’ve previously written about Arbutus’ patent disputes with Moderna and Pfizer. In Arbutus’ case against Pfizer, the court recently conducting a claim construction hearing. Before that hearing, Pfizer argued that many of Arbutus’ patents are “indefinite.” The court held it was premature for Pfizer to make this argument, but Pfizer nonetheless established that when the case reaches summary judgment, it will rely upon the doctrine of indefiniteness to prevail against Arbutus.

Read MoreThe biosimilars are biting. And they are biting at three big biologics distributed by Roche through its biotech subsidiary, Genentech. 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?
