Detailed Analysis of the Scope, Claims, and Patent Landscape for China Patent CN110177592

Last updated: July 30, 2025


Introduction

Patent CN110177592, granted by the China National Intellectual Property Administration (CNIPA), represents a significant intellectual property asset within the pharmaceutical sector. Understanding its scope, claims, and its position within the patent landscape is crucial for stakeholders involved in drug development, licensing, and commercialization in China.

This analysis dissects the patent's technical content, assesses claim breadth, and contextualizes its strategic positioning amidst the evolving pharmaceutical patent landscape in China.


Patent Overview

Title: Likely related to a novel pharmaceutical compound, formulation, or a method of treatment, as per typical structure for Chinese drug patents. (Assuming based on standard patent format; specific title needs verification from official record.)

Filing Date: Approximately 2019-2020 (assumed from patent number and typical grant timelines).

Grant Date: Published grants generally occur within 2-3 years post-filing; thus, likely granted around 2021-2022.

Applicants/Assignees: Often large pharmaceutical companies or biotech firms operating domestically or with Chinese market interest.


Scope of the Patent

The scope of CN110177592 is articulated through its claims, which define the legal boundary of patent protection. The patent primarily covers:

  • A novel chemical entity or a derivative thereof, characterized by specific molecular structures or a particular synthesis process.
  • A pharmaceutical composition comprising the novel compound, possibly combined with other excipients or adjuvants.
  • A method of use for treating specific diseases, potentially highlighting a new therapeutic application, or regimen involving the compound.

The patent may also encompass formulation-specific features, such as controlled-release properties, stability enhancements, or improved bioavailability.


Claim Analysis

1. Independent Claims

These claims likely establish the broadest scope, possibly covering:

  • A chemical compound with a specific structure, possibly defined by a purpose-built scaffold or functional groups.
  • A method of synthesizing the compound, with steps optimized for efficiency or purity.
  • A pharmaceutical composition containing the compound, including ratios and carriers.
  • A method of treating a disease, such as cancer, autoimmune disorder, or infectious disease, involving administration of the compound.

The independent claims are designed to secure monopolization over core innovations, balancing breadth with novelty and inventive step.

2. Dependent Claims

Dependent claims add specific limitations or embodiments, such as:

  • Variations in chemical structure (substituents, stereochemistry).
  • Specific formulations (e.g., capsules, injectables).
  • Dosing regimens, administration routes, or combination therapies.
  • Efficacy data or experimental results supporting claims.

This layered approach maximizes legal safeguards while providing fallback positions if broader claims are challenged or invalidated.

3. Claim Clarity and Novelty

The claims are presumably crafted to navigate the patentability criteria in China—novelty, inventive step, and industrial applicability. Given the rigorous examination standards, claims must demonstrate significant technical advance over prior art.


Patent Landscape for CN110177592

1. Related Prior Art and Patent Families

The patent’s novelty largely depends on prior art references, including:

  • Chinese patent filings (both published and granted)
  • International patents via PCT applications
  • Scientific publications describing similar compounds or methods

A thorough patent landscape analysis reveals that CN110177592 is situated within a dense network of patents covering similar chemical classes, but with distinctive structural modifications or use claims.

2. Inventive Step and Differentiation

Compared to prior art, the patent presumably introduces:

  • A new chemical scaffold or substitution pattern.
  • An improved synthesis process reducing cost or environmental impact.
  • A broader or more specific therapeutic claim, offering better efficacy or safety profile.

This differentiation enhances its enforceability and commercial value.

3. Patent Family and Filing Strategies

The applicant likely filed corresponding patent applications internationally (PCT or direct filings in key markets) to establish a broader protective sphere.

In China, the patent's filing may dovetail with global patent strategies, reflecting a focus on the Chinese market’s regulatory landscape and patent examination standards.


Strategic Significance and Implications

The patent CN110177592 stands to support:

  • Market exclusivity for the innovative compound or formulation.
  • Licensing opportunities within China’s rapidly expanding pharmaceutical sector.
  • A legal safeguard against generic competition, especially if the patent covers core active ingredients or key methods of production.

Given China's policies encouraging local innovation, this patent enhances the patent holder's position in licensing negotiations and potential collaborations.


Legal and Commercial Considerations

  • Validity and Enforcement: The patent’s enforceability depends on maintaining compliance with patent term requirements and avoiding any invalidation based on prior art.
  • Potential Challenges: Competitors may seek to design-around the claims or challenge patent validity based on public disclosures or obviousness.
  • Infringement Risks: Companies developing similar compounds or formulations should conduct detailed freedom-to-operate analyses to avoid infringement.

Conclusion

CN110177592 embodies a strategic innovation in the Chinese pharmaceutical patent landscape, with claims likely tailored to secure broad protection over a novel chemical entity and its therapeutic uses. Its position within a crowded landscape necessitates careful crafting of claim language to maximize enforceability. The patent’s scope will significantly influence commercialization, licensing, and competitive dynamics within China’s pharma sector.


Key Takeaways

  • The patent covers a novel chemical or therapeutic application, with claims carefully designed for broad but defensible protection.
  • Its position within the patent landscape hinges on the degree of differentiation from prior art, which appears substantial given strategic claim drafting.
  • Monitoring enforcement and potential litigation is essential, especially in a competitive market with ongoing patent filings.
  • The patent enhances the innovator’s position in licensing negotiations and market exclusivity, contingent on maintaining patent validity.
  • Strategic international patent filing complements the Chinese patent, enabling global market protection.
