Legal Arguments and Defenses
Novartis’s Claims
- Infringement of Patent Claims: The patent claims cover the composition and manufacturing process of the drug. The allegation is that Lupin’s generic product directly infringes on these claims.
- Validity of Patent: Novartis asserts the patent’s validity, arguing it is novel and non-obvious, with supporting prior art analysis.
- Injunctive Relief and Damages: Novartis seeks to prevent Lupin’s sales before patent expiration and claims damages for infringement.
Lupin’s Defenses
- Non-Infringement: Argument that Lupin’s process/product does not infringe the patent claims.
- Invalidity of Patent: Challenges to novelty or non-obviousness, relying on prior art references [2].
- Patent Misuse or Inequitable Conduct: Possible allegations that patent was obtained or asserted misleadingly.
Legal Precedents and Standards
- Patent Infringement: Must prove that the accused product falls within the scope of at least one patent claim.
- Invalidity Claims: Must demonstrate prior art or obviousness rendering the patent invalid under 35 U.S.C. §§ 102, 103.
- Injunctions: Equitable considerations weigh whether injunctions are appropriate, balancing public interest and patent rights.
