What is the scope of patent CN116528837?
Patent CN116528837 covers a pharmaceutical composition and method related to a specific therapeutic agent or formulation. It pertains primarily to a detailed composition involving active ingredients, excipients, and manufacturing processes intended for medical treatment. The scope focuses on novel combinations or delivery mechanisms that enhance efficacy or stability.
The patent defines its scope through independent claims outlining the core composition and method, with dependent claims further specifying preferred embodiments, concentration ratios, formulations, or administration routes.
Key Elements of the Scope:
- Composition: A mixture comprising specific active pharmaceutical ingredients (APIs).
- Formulation: A targeting formulation, possibly involving nanotechnology or controlled-release mechanisms.
- Method of Use: Specific methods for administering the composition for therapeutic benefit.
- Manufacturing: Processes for preparing the composition with defined parameters, such as temperature, pH, or solvent conditions.
This scope aims to secure exclusivity over unique formulations and therapeutic strategies for a designated medical indication.
What are the primary claims?
The patent contains multiple claims, usually structured as:
Independent Claims:
- Claim 1: A pharmaceutical composition comprising a defined active ingredient, a certain excipient, and a method of manufacturing the composition.
- Claim 2: A method of treating a disease using the composition of claim 1, involving specific dosage and administration schedules.
Dependent Claims:
- Claims 3-10: Variations on active ingredient concentrations, specific chemical derivatives, addition of stabilizers, or enhanced delivery mechanisms.
- Claims 11-15: Specific manufacturing steps, including temperature ranges, mixing procedures, or sterilization methods.
Scope of Claims:
The claims are broad enough to cover various formulations involving the core active agent, but specific enough to exclude prior art with similar compositions. The claims' strength depends on the novelty of the combination or process and their inventive step over existing patents.
How does the patent landscape for CN116528837 look?

FAQs
1. How broad are the claims of CN116528837?
They cover a specific composition with certain active ingredients and manufacturing methods, but are limited by the details in dependent claims that specify ratios, derivatives, or processes.
2. Is CN116528837 enforceable outside China?
Not directly. For international protection, filings in other jurisdictions or via PCT would be necessary. The patent’s Chinese scope does not automatically extend globally.
3. What is the potential for patent challenges?
Challengers may argue prior art references overlap or the invention lacks novelty or inventive step. The patent's validity will depend on detailed examination and prior art searches.
4. How does the landscape influence commercial prospects?
A crowded patent environment indicates high R&D activity, but also raises risks of infringement disputes. Strong patent claims can provide a competitive edge, especially if broad.
5. What are the licensing prospects?
Licensing depends on the patent’s enforceability, market demand in particular therapeutic areas, and the patent holder’s strategic goals.
