Defendant’s Position: Handa disputes the infringement allegations, asserting that its products do not contain the patented compositions or utilize the patented methods. Handa also challenges the validity of the patents, citing prior art references and lack of inventive step.
Procedural History
- Initial Complaint: Filed on July 16, 2021, with claims for patent infringement and injunction.
- Temporary Restraining Order (TRO): Novartis sought an emergency TRO to prevent Handa from selling infringing products; the court denied initial TRO, requiring further evidence.
- Claim Construction Proceedings: Both parties engaged in Markman hearings to interpret patent claims.
- Amended Pleadings: Amendments included additional claims and patents in dispute.
- Discovery: Ongoing, with Handa requesting documents and deposition of Novartis experts.
- Settlement Discussions: No public record of recent settlement; case remains active.
Patent Litigation Strategy and Risks
Novartis risks include:
- Patent validity challenges: Prior art and obviousness defenses may threaten patent enforceability.
- Non-infringement defenses: Handa may demonstrate non-infringement by product design.
- Market impact and injunctions: If patents are upheld and infringement proven, Novartis could seek injunctive relief and damages.
Handa’s risks include:
- Patent infringement liability: Potential damages for patent infringement if found liable.
- Invalidity claims: Successful prior art defenses could invalidate patents.
- Market disruption: Litigation delays and potential injunctions could affect Handa’s product rollout.
