FAQs
-
Can the claims be challenged based on prior art?
Yes. Similar chemical structures or therapeutic methods disclosed before 2014 can serve as grounds for invalidation or opposition.
-
What is the patent’s geographic scope?
The patent applies only within Japan. International protection requires filings in other jurisdictions.
-
Are derivative compounds protected?
Yes. Claim 2 covers derivatives such as salts and polymorphs, expanding the patent’s protection.
-
What are the main risk factors for generic entry?
Narrow compound claims, potential prior art references, and patent expiry date in 2034.
-
How active is the patent family internationally?
Several patents and applications are filed under PCT or directly in other regions, indicating a global R&D strategy.
