FAQs
Q1. What are common grounds for patent invalidity in pharma litigation?
A1. Obviousness, lack of novelty, insufficient disclosure, and indefinite claims.
Q2. How does PTAB inter partes review influence patent disputes?
A2. It allows for challenging patent validity early in litigation, potentially invalidating claims before or during court proceedings.
Q3. What remedies are typically sought in patent infringement cases?
A3. Injunctive relief, monetary damages (including royalties), and attorneys' fees.
Q4. How does regulatory approval impact patent enforceability?
A4. FDA approval can facilitate market entry but does not automatically extend patent protections; patent exclusivity is separate but interconnected.
Q5. What strategic steps should pharma companies take to protect patents?
A5. Conduct comprehensive prior art searches, file broad and detailed patents, actively monitor infringing activities, and engage in timely legal actions.
