FAQs
1. Is KR20240157128 likely to block generics in South Korea?
Yes, if the claims cover core compounds and formulations broadly, it can limit generic development in South Korea.
2. Can the patent be challenged on grounds of obviousness?
Potentially. If prior art shows similar compounds with minor modifications, challengers can argue non-inventiveness.
3. Are method of use claims included?
Most likely, considering South Korean patent law supports second medical use protections; these extend coverage beyond chemical compounds.
4. How does the patent landscape affect R&D strategies?
Firms must analyze the overlapping patent portfolios to identify freedom-to-operate or opportunities for licensing.
5. What are the key considerations for patent expiry?
Maintaining annual fees and possibly applying for patent term extension if clinical trials delay patent term.
