FAQs
Q1: What makes the claims of the '779 patent potentially broad or narrow?
A: The breadth depends on how general the structural and method language is. Broad claims cover extensive variations, but they risk invalidation if antedated by prior art. Narrow claims focus on specific embodiments, offering stronger validity but less protection.
Q2: Can competitors develop similar drugs without infringing this patent?
A: Possibly, if they design around the claims by modifying the chemical structure, formulation, or delivery method sufficiently to avoid infringement under the doctrine of equivalents.
Q3: What strategies can the patent holder employ to enforce or defend this patent?
A: Enforcement involves patent infringement litigation, while defense may include validity challenges, such as prior art reexaminations or patent oppositions.
Q4: How does the patent landscape influence the timing of generic entry?
A: The scope and validity of patents like the '779 patent can delay generic approval, maintaining market exclusivity longer, especially if patent extensions or supplementary protection certificates are secured.
Q5: Are there international equivalents of this patent?
A: Likely, given the strategic importance, with filings in jurisdictions such as Europe, Japan, and China to protect global market interests.
