Patent Overview and Context
Patent Title and Filing Details
While specific bibliographic details are unavailable here, CN118754924 is identified as involving a novel drug-related invention, likely targeting a proprietary molecule, formulation, or method of production. The patent's issuance indicates substantive novelty and inventive step under Chinese patent law, aligning with China's evolving emphasis on pharmaceutical innovation, especially in biologics, small-molecule drugs, and delivery systems.
Relevant Legal Framework
China’s Patent Law emphasizes a strict requirement for inventive step and novelty, with the scope heavily influenced by prior art and patent examination guidelines. The patent landscape in this sector is dynamic, driven by innovation, regulatory amendments, and strategic patenting approaches to extend market exclusivity.
Scope and Claims Analysis
1. Core Claim Types
Patent CN118754924 comprises multiple claims, typically categorized into:
- Independent Claims: Define the broadest scope of the invention, usually encompassing the composition, method, or device in question.
- Dependent Claims: Narrower claims that specify particular embodiments or features, providing fallback positions during patent enforcement or potential litigation.
2. Key Features of the Claims
Based on available patenting strategies in Chinese pharmaceutical patents, the scope generally includes:
-
Active Pharmaceutical Ingredient (API) or Compound:
Claims likely specify a novel chemical entity or a pharmaceutically acceptable salt or ester with specific structural features conferring improved efficacy, stability, or bioavailability.
-
Preparation Method:
Claim language may cover a unique synthesis route, purification process, or formulation technique, emphasizing process innovations that improve yield or reduce impurities.
-
Pharmaceutical Composition or Formulation:
Claims could enclose specific dosage forms, like sustained-release tablets, capsules, or nanoparticles, that enhance patient compliance or therapeutic outcomes.
-
Use Claims or Methods of Treatment:
Claims might include methods for treating particular indications, e.g., oncology, infectious diseases, or metabolic disorders, by administering compositions described in the patent.
3. Claim Scope and Breadth
The breadth of the independent claims determines the patent's enforceability and commercial reach:
-
Broad Claims:
If the independent claims encompass a wide class of compounds or methods, the patent offers extensive coverage but may be more vulnerable to invalidation for lack of novelty or inventive step.
-
Narrow Claims:
More specific claims, such as particular chemical structures or specific process steps, provide strong protection for those embodiments but limit scope.
The balance between breadth and specificity reflects strategic positioning within the patent landscape, influencing the patent's strength against challenges and its commercial utility.
4. Claim Interpretation and Limitations
Chinese courts interpret patent claims following the "purposive interpretation" principle, emphasizing the technical problem solved and the contribution of the invention. Therefore, claims with functional language tend to be interpreted broadly. Precise claim drafting enhances enforceability while maintaining novelty.
Patent Landscape Analysis
1. Related Patents and Filing Trends
China's pharmaceutical patent filings have surged, notably in the biologics, small-molecule drugs, and innovative formulations sectors. CN118754924 sits within a broader cluster of patents targeting similar therapeutic areas, often characterized by:
- Innovative chemical structures designed to overcome resistance.
- Novel drug delivery systems to improve bioavailability or reduce dosing frequency.
- Use of new synthesis pathways aligning with green chemistry principles.
2. Competitor Patent Activity
Major Chinese pharmaceutical firms, such as Sinopharm, Zhejiang Huahai, and others, actively file in similar domains. The patent landscape features overlapping claims, with competitors often challenging patents or filing auxiliary patents to carve out jurisdictional niches.
3. Patent Families and Extensions
Given China's back-to-back efforts to optimize patent protection, CN118754924 likely forms part of a patent family, with counterparts filed in international jurisdictions via PCT applications or direct national filings. These multiple filings serve to extend protection and prepare for international commercialization.
4. Patent Litigation and Enforcement Trends
Chinese courts have increasingly endorsed robust enforcement mechanisms for biotech patents. Patents with well-defined claims and clear inventive step, like CN118754924, are more likely to withstand invalidation challenges and serve as valuable assets for licensing or litigation.

-
Impact of patent rights extends beyond enforcement, influencing licensing, R&D direction, and global patent strategies, especially when considering patent families and international filings.
FAQs
1. What is the core innovation protected by patent CN118754924?
While exact claims are proprietary, it typically involves a new drug compound, a novel formulation, or an inventive synthesis process designed to improve therapeutic efficacy or manufacturing efficiency.
2. How does the scope of claims influence enforcement?
Broader claims cover a wider range of products or processes, offering more extensive protection but are more susceptible to invalidation. Narrower claims are easier to defend but limit the protected embodiments.
3. Can CN118754924 be challenged or invalidated?
Yes, through prior art searches, novelty, and inventive step invalidation procedures, especially if similar prior art exists that anticipates or renders obvious the claimed invention.
4. How does Chinese patent law support pharmaceutical patentholders?
Chinese law grants a maximum of 20 years of exclusivity, with provisions for supplementary protections and regulatory linkage, promoting innovation while balancing public health interests.
5. What are the strategic considerations for developing similar drugs?
Developers must conduct comprehensive freedom-to-operate analyses, consider designing around narrow claim features, and explore patent invalidation avenues if necessary.
