Background and Context
The litigation between AbbVie Inc. and Sandoz Inc., filed as 3:18-cv-12668 in the District of New Jersey, is part of a broader landscape of patent and regulatory disputes in the pharmaceutical industry. Here, we delve into the key aspects of this case.
Nature of the Action
This civil action revolves around patent infringement claims related to AbbVie's pharmaceutical products. Specifically, AbbVie alleged that Sandoz's submission of an Abbreviated New Drug Application (ANDA) for a generic version of one of its drugs infringed several of its patents[2].
Patents in Dispute
The litigation involves multiple patents held by AbbVie, including U.S. Patent Nos. 11,542,239, 11,690,845, 11,690,854, and 11,707,464. These patents are crucial for protecting AbbVie's intellectual property related to its pharmaceutical products, particularly those in the immunology sector[2].
ANDA and Notice of Paragraph IV Certification
Sandoz filed an ANDA with the FDA, seeking approval to market a generic version of AbbVie's drug. As part of this process, Sandoz provided a Notice of Paragraph IV Certification, asserting that the patents in question were invalid or would not be infringed by their generic product. This notice is a standard procedure under the Hatch-Waxman Act, which allows generic manufacturers to challenge the validity or applicability of patents held by the brand-name drug manufacturer[2].
Claims and Counterclaims
AbbVie filed a complaint alleging patent infringement by Sandoz based on the ANDA submission and the Notice of Paragraph IV Certification. Sandoz, in response, likely argued that the patents were invalid or not infringed, and may have also raised defenses such as preemption under federal law or other affirmative defenses[2].
Discovery Disputes
A significant aspect of this litigation involves discovery disputes, particularly related to manufacturing information. Sandoz had planned to make changes to its manufacturing process, and AbbVie sought to delay summary judgment until Sandoz submitted its modified manufacturing process to the FDA and produced the underlying documents. However, the district court found that the requested information was not material to the finding of non-infringement and granted summary judgment of non-infringement in favor of Sandoz[3].
Appeal and Further Litigation
AbbVie appealed the district court's decision, arguing that without the requested discovery, they could not determine the details of Sandoz's modified process and thus could only provide a preliminary infringement analysis. This appeal highlights the ongoing battle over access to detailed manufacturing information, which is crucial for determining patent infringement in complex pharmaceutical cases[3].
Broader Implications
This litigation is part of AbbVie's broader strategy to protect its lucrative pharmaceutical products, such as Rinvoq, from generic competition. AbbVie has been aggressively litigating to maintain its market exclusivity, especially as its blockbuster drug Humira faces biosimilar competition. The outcome of this case could have significant implications for the timing and extent of generic entry into the market[5].
