What is the procedural history?
- The complaint was filed on January 30, 2024.
- Aurobindo filed an answer on March 15, 2024, denying infringement and asserting non-infringement and patent invalidity defenses.
- The court has granted a motion to stay discovery pending resolution of the validity issues, pending a Patent Office inter partes review filed by Aurobindo.
What are the key legal issues?

FAQs
1. How does patent validity affect the case?
Patent validity determines whether Bayer can enforce it. Aurobindo’s IPR challenges validity, which could lead to patent cancellation or narrowing, affecting infringement claims.
2. What is the role of the PTAB in this case?
The PTAB reviews patent validity through inter partes review. Aurobindo’s IPR delays proceedings and aims to invalidate the patent, impacting Bayer’s enforcement options.
3. How might this case impact the generic drug market?
If Bayer’s patent is invalidated, Aurobindo and other generics can enter the market earlier, increasing competition and reducing prices.
4. What damages can Bayer seek if it wins?
Bayer can seek monetary damages, including lost profits or reasonable royalty, and injunctive relief to prevent further infringement.
5. What are the potential outcomes?
The case may result in the patent being upheld, invalidated, or narrowed, or Aurobindo settling. Each outcome affects market exclusivity and competition.
