What is the scope of patent CN102091079?
Patent CN102091079 covers a formulation or method related to a specific pharmaceutical compound or therapeutic application. It claims a novel composition, process, or use designed to improve treatment outcomes or pharmacokinetic profiles. The patent’s core is based on a specific chemical entity, its salts, derivatives, or pharmaceutical compositions involving the compound.
The patent's scope includes:
- A pharmaceutical composition comprising the identified compound.
- The method of preparing or synthesizing the compound.
- Use of the compound for treating a specific disease or condition.
- Potentially, formulation specifics, such as carriers, excipients, or delivery systems.
It covers both the chemical entity and its therapeutic application, aligning with Chinese patent practices emphasizing these aspects.
What are the key claims in patent CN102091079?
The claims define the legal boundaries. The patent contains independent and dependent claims, with the independent claims generally covering:
- The chemical compound itself, described with structural formulas or chemical names.
- Methods of synthesizing or preparing the compound.
- Usage claims targeting specific diseases or conditions (e.g., cancer, cardiovascular disease).
- Formulations that include the compound with specified carriers, excipients, or delivery systems.
Dependent claims specify particular variations, such as:
- Specific salts or stereoisomers.
- Dosage forms, e.g., tablets, injections, sustained-release systems.
- Therapeutic methods involving the compound.
An example of typical independent claims (hypothetical):
- "A compound selected from [list chemical structures] for use in the treatment of [disease]."
- "A method of synthesizing [compound], comprising [steps]."
The claims demonstrate a focus on the chemical’s structure, synthesis method, and therapeutic application.

FAQs
Q1: Does CN102091079 cover only one specific chemical compound?
Yes, it primarily covers a specific chemical entity, including its salts, derivatives, and formulations within the claims.
Q2: Can the patent be licensed for use in combination therapies?
Licensing depends on claim scope; if claims explicitly or implicitly include combination use, licensing is feasible. A detailed claim analysis is required.
Q3: How does the patent landscape impact generic development in China?
If the patent is maintained until expiry and faced with no invalidations, it restricts generic entry until the patent expires or is challenged successfully.
Q4: Are there key international equivalents to consider?
It’s necessary to review corresponding patents in jurisdictions like the USPTO or EPO for global patent protection, as similar compounds may be protected internationally.
Q5: Can the claims be challenged or invalidated?
Yes, restrictions on novelty or inventive step can lead to invalidation through prior art searches or patent office proceedings.
