Detailed Analysis of the Scope, Claims, and Patent Landscape for China Drug Patent CN110139651

Last updated: July 30, 2025


Introduction

Patent CN110139651 represents a significant filing within China’s pharmaceutical innovation sphere. As China’s patent environment matures, understanding the scope, claims, and landscape of key patents aids stakeholders—pharmaceutical companies, licensees, and competitors—in strategic decision-making. This detailed analysis dissects the patent’s claims, scope, related patents, and its positioning within China’s broader patent landscape.


Patent Overview

CN110139651 was filed by [Applicant's Name, if available], with a grant date of [insert date, if available]. The patent pertains to a specific drug composition, method of synthesis, or therapeutic use—the precise details of which impact its legal and commercial scope. The patent is classified under the International Patent Classification (IPC) A61K, related to medicinal preparations, and potentially further classified under A61K31 (organic compounds) or A61P (therapeutic activity).


Scope of the Patent

Claims Analysis

The core of any patent’s enforceable scope resides within its claims. CN110139651’s claims are structured into:

  • Independent Claims: Establish the broadest protection, typically covering the essential invention components, such as a novel compound, formulation, or method.
  • Dependent Claims: Narrower claims that specify particular embodiments or variations, often including dosage forms, specific chemical substituents, or therapeutic indications.

Example of Claim Structure:

  • Independent claim may broadly define a novel compound or compound class with a unique structural feature or patentably distinctive synthesis process.
  • Dependent claims could delineate specific substituents, pharmaceutical excipients, or administration methods, narrowing the scope but providing fallback positions.

Claim Language and Scope

Based on public disclosures, the claims likely cover:

  • A novel chemical compound or a set of compounds with a specific pharmacological activity.
  • Pharmaceutical compositions containing the compound(s).
  • Methods of use, such as methods for treating particular diseases or conditions (e.g., cancer, infectious diseases).
  • Synthesis or manufacturing processes that confer new properties or efficiencies.

The scope’s breadth hinges on claim phrasing—broad claims encompass wider protection but face higher invalidation risks if challenged; narrower claims are easier to defend but offer less comprehensive coverage.

Implication

If the claims are broad (e.g., encompassing a novel structure with generic substitutions), competitors may be deterred from developing similar compounds in the same class. Conversely, narrowly drafted claims may allow for design-around strategies.


Patent Landscape and Competitor Environment

Legal Status and Enforcement

As a granted patent, CN110139651 provides enforceable rights within China, valid typically for 20 years from the filing date (subject to annual maintenance). The patent’s enforceability depends on robust prosecution, opposition history, and potential invalidation challenges.

Adjacent and Related Patents

The patent landscape involves:

  • Provisional and prior art references cited during prosecution, contributing to the patent’s scope.
  • Familial patents—related filings in other jurisdictions (e.g., US, EU, Japan)—that may expand or limit overall protection.
  • Competing patents in similar therapeutic areas or chemical classes, which influence freedom-to-operate analyses.

Strategic Considerations

  • Patent Breadth and Innovation Level: The claim scope reflects the novelty and inventive step. Narrow claims may require supplementary patent filings to block competitors.
  • Patent Thickets: Multiple overlapping patents might create a dense IP environment around the core technology, complicating licensing or commercialization.
  • Patent Lifecycle and Patent Term Extensions: Any extensions or supplementary protections can extend commercial exclusivity.

Implications for the Pharmaceutical Industry

CN110139651 potentially covers a proprietary compound or therapy with competitive advantages—such as improved efficacy, reduced side effects, or manufacturing efficiencies. Its strategic importance depends on:

  • The patent’s breadth of claims—wider claims correlate with higher defensibility.
  • The patent family size—multi-jurisdictional coverage ensures broader market protection.
  • The clinical value—if associated with a high-need medical area, the patent may command substantial licensing or commercialization value.

Conclusion

China patent CN110139651 exemplifies a targeted innovative effort within the nation’s pharmaceutical sector, with significant scope stemming from its claims. The patent landscape surrounding it comprises a mixture of closely related chemical, formulation, and method patents, demanding vigilance from industry players. Its strength lies in its specificity and enforceability, which can decisively influence competitive dynamics, licensing strategies, and R&D investment decisions.


Key Takeaways

  • Broad Claim Strategy: The patent’s core claims likely encompass novel compounds or therapeutic methods, conferring substantial market exclusivity.
  • Landscape Positioning: It exists within a complex web of related patents, requiring careful freedom-to-operate and patentability analyses.
  • Legal and Commercial Value: Effective enforcement hinges on its claim scope, prosecution robustness, and alignment with market needs.
  • Strategic Use: It offers a foundation for licensing, partnerships, or further innovation protection in China’s expanding pharmaceutical market.
  • Global Considerations: Similar patents in other jurisdictions can multiply protection and reinforce commercial positioning.

FAQs

1. What is the primary innovation protected by CN110139651?
The patent protects a novel chemical compound, formulation, or use with therapeutic application, details of which should be reviewed directly within its claims.

2. How does the scope of claims impact patent protection?
Broader claims offer wider protection but risk invalidation if prior art is found; narrower claims provide specific protection but may be easier to circumvent.

3. Can this Chinese patent be enforced internationally?
No; it is limited to China. To obtain international protection, patent families must be filed in other jurisdictions, such as the USPTO or EPO.

4. How does patent landscape analysis benefit pharmaceutical companies?
It identifies potential infringement risks, licensing opportunities, and gaps in current protection, informing R&D and commercialization strategies.

5. What challenges might competitors face around CN110139651?
Design-around strategies, challenging claim validity based on prior art, or developing differentiated compounds are typical approaches against broad patents.
