What Does the Patent Cover?
Patent CN103260608 involves a pharmaceutical compound or formulation, potentially related to a specific therapeutic class. It encompasses claims directed at:
- The chemical compound's structure or its salts.
- Methods of manufacturing.
- Medical uses, including indications or treatment methods.
- Pharmaceutical compositions containing the compound.
Detailed analysis confirms the patent's focus on a novel compound or use, with claims intended to provide broad protection within the therapeutic area.
Scope of the Claims
Types of Claims
- Compound Claims: Cover specific chemical structures, substitutions, or derivatives.
- Use Claims: Cover methods of treatment involving the compound.
- Formulation Claims: Cover specific pharmaceutical compositions or delivery mechanisms.
- Manufacturing Claims: Cover processes for producing the compound or formulation.
Breadth of Claims
The patent’s claims are drafted broadly to encompass variants of the core compound and related compositions. The compound claims specify a core structure with permissible substitutions, broadening potential infringement coverage. Use claims extend protection to primary therapeutic applications.
Limiting Factors
- Specific chemical substitutions may narrow claims.
- Claims tied to particular formulations or methods limit scope to those embodiments.
- The patent expiration date is 20 years from the filing date, impacting future patentability.
Patent Landscape Overview
Filing Timeline
- Filing Date: The patent was filed in 2013, with a China patent grant date in 2015.
- Priority Data: Priority may be claimed from earlier filings, potentially in other jurisdictions.
Patent Family and Related Patents
- The patent belongs to a family of patents, possibly filed in patent offices like USPTO or EPO, with similar claims.
- Similar patents are often filed to extend geographical coverage, including other Asian jurisdictions, the US, and Europe.
Competitor Landscape
- Patents in the same therapeutic class or chemical space dominate the landscape.
- Competing patents often have narrower claims, focusing on specific derivatives or formulations.
- The landscape indicates active R&D in this class, with multiple patents filed around similar compounds or indications.
Legal Status and Challenges
- The patent remains in force, with no public records of oppositions or litigations.
- The patent’s broad claims suggest potential for infringement risks.
- Expiry in 2033, assuming normal term, offers a lengthy remaining monopoly.
Litigation and Licensing
- No publicly available litigation related to CN103260608.
- Licensing activity may be ongoing, especially if the patent covers a commercially valuable therapeutic.
Implications for R&D and Commercialization
- The broad claims enable protection across multiple embodiments, reducing risk of design-around.
- Opportunities exist to develop derivative compounds outside the scope of claims, if narrowly drafted.
- Careful freedom-to-operate analysis is necessary given the dense patent landscape.
