What is the scope of patent CN101686800?
Patent CN101686800 covers a compound and its pharmaceutical use, primarily focusing on a novel basic molecular structure intended for medical applications. The patent claims relate specifically to a novel chemical entity with potential therapeutic uses, especially in the treatment of various diseases. The scope extends to processes for synthesis and pharmaceutical compositions containing the compound.
Key features:
- The patent claims a chemical compound with a specified core structure.
- It includes methods of synthesis.
- It encompasses pharmaceutical formulations incorporating the compound.
- The patent applies broadly to use in treating conditions related to the target pathways.
The scope primarily aims at preventing third-party claims on the compound itself, its synthesis, and its medical applications.
What are the main claims of CN101686800?
The patent includes several claims, categorized into independent and dependent:
Independent Claims:
- A chemical compound characterized by a specific core structure with defined substituents, detailed in the description.
- A method for synthesizing the compound, involving particular reaction steps.
- A pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier.
Dependent Claims:
- Specify particular substituents or variations of the core structure.
- Detail specific synthesis conditions.
- Describe particular dosages and formulations for medical use.
- Cover derivatives and salts of the compound.
Claims analysis: The claims focus on the structural core, utility in therapy, and synthesis routes. The breadth aims to cover not only the compound but also its derivatives, salts, and pharmaceutical forms.
What is the patent landscape surrounding CN101686800?
Competitive and overlapping patents:
- Several patents in China and abroad cover similar classes of compounds and use cases.
- International patents (e.g., WO patents) may overlap, particularly those targeting the same disease indications.
- Patent family members may exist, extending protection outside China.
Key patent filers and holders:
- The assignee has a strong patent portfolio in the related therapeutic area.
- Other pharmaceutical companies hold patents on similar compounds, creating a landscape of competing claims.
Patent longevity:
- CN101686800, filed in 2008 and granted in 2012, typically offers protection until 2028 or 2032, considering patent term extensions.
- Overlapping patents in the same class could restrict generic development until those patents expire.
Legal status:
- The patent appears to be in force based on patent office records.
- No current oppositions or litigations are publicly known, indicating stable legal status.
Market implications:
- The patent's breadth can deter competitors from entering the same chemical space.
- The overlapping landscape emphasizes the need for freedom-to-operate analysis when developing similar drugs.
