FAQs
-
What types of claims are most common in VN34404?
Composition and use claims are primary, covering the specific API and its therapeutic applications.
-
Can competitors develop similar compounds without infringement?
Potentially, if new compounds differ significantly in chemical structure or use claims are narrowly scoped.
-
What is the patent’s territorial scope?
It grants protection only within Vietnam unless backed by a broader international patent family.
-
How does the patent landscape influence the launch of generic versions?
Patent expiry or invalidation procedures offer pathways; the scope affects how easily generics can proceed.
-
What should R&D teams consider for freedom-to-operate analyses?
Review claims against existing patents globally and domestically, especially in jurisdictions with overlapping patent families.
