The case has scheduled trial dates for 2023, with preliminary motions and appeal processes potentially extending the timeline by 1–3 years.
2. What is the significance of patent validity challenges?
Challenging patent validity can lead to a court ruling that a patent should not have been granted, enabling generics to enter the market legally.
3. How does patent infringement impact a drug's market?
Infringement rulings that uphold patent rights prevent competitors from launching generics, maintaining market exclusivity for the patent holder.
4. What role does FDA approval play?
