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?
Read MoreTrillium Therapeutics is a clinical stage immune-oncology company that focuses on cancer treatments, and in particular, treatments that inhibit CD47. Trillium is among a group of drug candidates exploring CD47 targeting agents that are attracting investment from Big Pharma. Pfizer recently announced a $25M investment in Trillium. In conjunction with developing its own two CD47-inhibitor candidates, Trillium is also building out its patent portfolio. On February 2, 2021, two additional U.S. patents issued to Trillium, including U.S. Patent Nos. 10,906,954 and 10,907,209. Will Trillium’s patents offer protection against brand competitors or eventual biosimilars?
Read MoreWhen does a pile of sand become a heap? When is a portfolio of patents too many patents? Can using too many patents to compel generics to take a later entry date turn into monopolistic conduct? These questions lurk the heart of the antitrust litigation brought by buyers of the blockbuster drug, Humira®, against its manufacturer, AbbVie ($ABBV). The case is currently pending within the Northern District of Illinois (In Re: Humira (Adalimumab) Antitrust Litigation, No. 19-cv-1873 (N.D. Ill.)). We previously blogged about related allegations before the case was filed when Boehringer Ingelheim raised them within its biosimilar litigation against AbbVie. On June 8, 2020, the Illinois federal court dismissed the antitrust action pursuant to AbbVie’s motion to dismiss. What are the takeaways from the case?
Read MoreThe American University Law Review recently published a very timely and compelling article on the intersection between the Hatch-Waxman Act and the BPCIA, on the one hand, and post-grant proceedings at the PATB, on the other. The article, which is titled, Ships in the Night: Resolving Administrative Conflict Between FDA- and Patent-Related Legislation, American Univ. Law Review [Vol. 68:1111], (hereinafter, “Garcia & Stroud”), is authored by Carlos A. Garcia, Patent Counsel, Eli Lilly & Company, and Jonathan Stroud, Chief IP Counsel, Unified Patents Inc. The article is a comprehensive and thorough overview of how petitions for inter partes review and other post-grant proceedings may be impacting efficient resolution of patent issues for generic drugs.
Read MoreAnd 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 MoreBoehringer Ingelheim has been one of the lone holdouts in AbbVie’s ($ABBV) campaign to delay biosimilar competition against Humira® until 2023. To date, AbbVie has settled with almost all proposed biosimilars for entry dates in 2023. Is Boehringer going to launch at-risk?
Read MoreBoehringer Ingelheim has claimed that AbbVie wrongfully created a “patent thicket” around Humira®, and it is delaying biosimilar competition. While that defense is unique, and may be hard to prove on its face, the FDA appears to agree with Boehringer. Did AbbVie create a wrongful “patent thicket” around Humira®?
Read MoreAbbVie ($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 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?
Read MoreSandoz was denied institution on two IPRs against Humira® patents owned by AbbVie. As we previously discussed, in late 2017, Sandoz filed eight different IPRs against Humira® patents. Two of those IPRs just failed to reach institution. What are the take-aways, for Sandoz and any other Humira® biosimilars?
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.
