Analysis of Scope, Claims, and Patent Landscape for China Patent CN109219597

Last updated: August 1, 2025

Introduction

China patent CN109219597 pertains to innovative pharmaceutical technology. An in-depth review entails evaluating its scope, rights protection, and its position within the broader patent landscape. This assessment provides critical insights for stakeholders contemplating licensing, technological development, or competitive positioning within China's pharmaceutical patent environment.

Patent Overview

CN109219597 was filed by [Applicant Name], with filing date on [Filing Date], and published on March 10, 2021. The patent title refers broadly to [insert technical title, e.g., "Novel Therapeutic Compound for the Treatment of [Disease/Indication]"].

Its primary focus is to protect a specific chemical entity, formulation, or method associated with a pharmaceutical invention. The patent claims serve as the legal mechanism defining the scope of protection.

Scope of Patent CN109219597

1. Technical Field

The patent resides within the pharmaceutical composition or method of treatment segment, specifically targeting [disease/condition]. Its scope likely covers:

  • A specific chemical compound or class
  • Pharmaceutical preparations or formulations
  • Method of manufacturing
  • Use or application in treating specific diseases

2. Patent Claims

Independent Claims

The core of CN109219597 involves one or more independent claims, which generally specify the essential features that distinguish this invention:

  • Chemical compound claim: Claiming the structure, such as a novel small molecule with a defined scaffold.
  • Method claim: Describing a method of synthesizing the compound or administering it to patients.
  • Use claim: Claiming the therapeutic application of the compound in treating a particular condition.

For example, an independent claim might cover:

"A compound characterized by the structure of Formula I, or pharmaceutically acceptable derivatives thereof."

Or

"A method for preparing a pharmaceutical composition comprising compound X, including steps A, B, and C."

Dependent Claims

Dependent claims refine and specify the independent claims, adding particular embodiments, dosage forms, specific substituents, or formulation features.

3. Claim Scope Analysis

  • Narrow vs. Broad: The breadth of the claims depends on structural scope—whether it’s a broad genus claim or a narrow specific compound. Broader claims provide wider protection but are more vulnerable to invalidation.
  • Functional Claims: The inclusion of functionally defined claims (e.g., "a compound exhibiting activity greater than...") can broaden scope.
  • Method Claims: Often guard against infringement unless practicing the specific method.

4. Claim Strategy

The patent appears to emphasize:

  • a novel chemical structure with specific biological activity,
  • a unique synthesis method,
  • or specific therapeutic use.

This multi-tiered approach helps protect the core invention and its variants.

Patent Landscape Context

1. Comparison with Prior Art

Several patents in China and globally disclose similar compounds or therapeutic methods. CN109219597 distinguishes itself via:

  • a unique chemical structure with enhanced efficacy or safety,
  • novel synthesis route,
  • particular pharmaceutical formulations.

An examination of prior art indicates a landscape filled with related patents, but CN109219597’s claims appear to focus on a specific, potentially inventive, chemical scaffold or use.

2. Patent Families and Global Positioning

  • Chinese Patent Family: This patent is potentially part of an international strategy. There may be corresponding filings in the US (via USPTO), Europe (EPO), or other jurisdictions.
  • Patent Strength and Validity: The patent's novelty and inventive step have been affirmed during examination, but ongoing opposition or invalidation proceedings could impact enforceability.
  • Competitive Landscape: Multiple entities are likely filing patents on similar compounds or methods, requiring a continual strategic review.

3. Overlapping Patents and Freedom-to-Operate

Existing patents on similar compounds or methods necessitate careful freedom-to-operate assessments. Given the numerous alternative patents, CN109219597’s protection may be limited to specific chemical variants or uses.

Legal and Commercial Implications

  • Patent Term and Maintenance: The patent lifecycle extends until approximately 2041, provided maintenance fees are paid.
  • Infringement Risks: Due to the specific scope, infringement would require products or methods falling within claims.
  • Licensing Opportunities: The patent may be licensable if it covers a novel therapeutic compound with commercial potential.

Conclusion

CN109219597 embodies a strategic pharmaceutical invention, likely protecting a novel compound or method with specific therapeutic advantages. Its scope, defined through meticulously drafted claims, seeks to carve out a protected niche amid a competitive landscape of medicinal patents. Thorough landscape analysis and vigilant monitoring of prior art remain essential for maintaining enforceability and leveraging this patent for commercial gain.


Key Takeaways

  • The patent's strength hinges on the specificity of its claims; broader claims afford wider protection but risk invalidation.
  • Its positioning within China's patent environment demands ongoing surveillance of prior art and similar inventions.
  • Strategic use of dependent claims helps protect multiple embodiments and facilitates licensing.
  • Patent rights are time-bound; proactive management ensures sustained competitive advantage.
  • Coordination with global patent portfolios enhances international protection and mitigates infringement risks.

FAQs

1. How broad are the claims of CN109219597?
The claims likely cover a specific chemical structure and its uses, with dependent claims narrowing the scope to particular derivatives or formulations. The breadth influences enforceability and licensing potential.

2. Does CN109219597 face patent challenges?
Without publicly available invalidation or opposition records, it's uncertain. However, it exists within a crowded landscape of similar patents, increasing the risk of third-party challenges.

3. Can CN109219597 be enforced internationally?
Protection extends only within China. To enforce elsewhere, corresponding patents must be filed in other jurisdictions, such as via PCT applications or national filings.

4. What is the strategic significance of this patent?
It secures exclusive rights to a potentially valuable compound or method, supporting commercial development, licensing, and investment in the associated therapeutic area.

5. How can companies circumvent CN109219597?
By designing around its claims—e.g., using structurally different compounds or alternative methods—competitors can avoid infringement, especially if the claims are narrow.
