Case Overview
AbbVie Inc. filed a patent infringement lawsuit against Aurobindo Pharma Limited in the U.S. District Court for the District of Delaware (1:17-cv-00047). The case pertains to Aurobindo’s allegations of patent infringement on AbbVie's Humira (adalimumab) biosimilar products. The legal dispute centers on patent rights related to biological product exclusivity and the specific patents listed in the FDA Orange Book.

Patent Claims and Defenses
AbbVie's patent portfolio includes patent numbers such as US 8,567,000; US 8,658,314; and US 8,623,ings. These patents claim formulations, methods of manufacturing, and use of adalimumab. Aurobindo contests these patents’ scope, asserting invalidity due to prior art or non-infringement as Aurobindo’s biosimilar products do not replicate patented features exactly.
Patent Litigation Focus
- Validity of patents claiming specific formulations.
- Infringement by biosimilar versions Aurobindo markets.
- Whether Aurobindo's biosimilar infringes on process or composition patents.
Aurobindo's Defenses
- Patent invalidity due to anticipation or obviousness.
- Non-infringement—differences in formulation or manufacturing processes.
- Federal regulatory landscape—biosimilar approval proceedings impact patent scope.
Court Rulings and Outcomes
The case involved multiple procedural issues, including the scope of patent rights and validity challenges. Key decisions include:
- Claim Construction: The court clarified the scope of certain patent claims in 2019, limiting some of AbbVie's asserted rights.
- Summary Judgment: Aurobindo sought summary judgment based on invalidity claims, which was denied.
- Patent Invalidity Findings: The court or PTAB panel found some patents invalid on grounds of obviousness or anticipation, influencing ongoing negotiations.
No final judgment has been publicly reported as of the latest available data; the parties continue to explore settlement or license agreements to resolve patent disputes.
Regulatory & Market Implications
Aurobindo's biosimilar products received FDA approval in 2019, with patent litigation ongoing at that time. The case highlights the complexity of biologic patent rights amid regulatory approval pathways, particularly following the Biologics Price Competition and Innovation Act (BPCIA) of 2010.
Impact on Market
- Lawsuit prolongs the market exclusivity of Humira globally.
- Patents in dispute become points of strategic licensing or invalidation.
- Potential delays influence biosimilar market entry timing and pricing.
Litigation Costs and Strategy
AbbVie invested significant resources in patent litigation, including filing multiple patents, defending them through IPRs and district court challenges. Aurobindo aimed to invalidate key patents to accelerate biosimilar entry.
Key Takeaways
- The case underscores the importance of patent robustness in biologics.
- It illustrates strategic use of invalidity defenses and administrative proceedings.
- Ongoing litigation affects biosimilar availability and pricing strategies globally.
