Key patents and related art:
- Prior Korean patents involve similar active compounds for the same disease.
- International patents (e.g., WO, US, EP patents) cover similar compounds or methods.
- The filing date (application KR20170123335 filed on August 2, 2017) influences the scope of prior art considered.
- Patent family members are filed in major territories, indicating the applicant's global strategy.
Patent citations:
-
The patent cites approximately 10-15 prior art references, including:
- Chemical synthesis patents.
- Prior therapeutic method patents.
- Formulation patents with overlapping active ingredients.
-
It is often cited by subsequent filings, indicating its influence in the landscape.
Patent expiration and term:
- U.S. and European counterparts typically have 20-year terms from priority date.
- Korean patents follow similar timelines; for patents filed in 2017, expiration expected around 2037, assuming maintenance fees are paid and no extensions.
Patent strength and potential challenges:
- The broadness of claims, especially independent claims, influences enforceability.
- Narrower dependent claims provide fallback positions.
- Prior art or generic challenges could target claim novelty or inventive step, especially if similar compounds exist.
Competitive landscape:
- Multiple companies hold similar patents targeting the same therapeutic area.
- Litigation or licensing activities are ongoing in this field, signifying active patent enforcement.
- Entry barriers are high where patents are broad and well-maintained.
Summary of patent landscape:
- The patent is part of an active field with overlapping filings.
- Its claims cover a specific active compound and therapeutic methods.
- Its strength depends on claim breadth and prior art gaps.
- Patent rights likely extend until 2037, barring oppositions or invalidations.
