Title: Comprehensive Analysis of Patent CN112423750: Scope, Claims, and Landscape in China’s Pharmaceutical Patent Sphere

Last updated: August 2, 2025


Introduction

The patent CN112423750 is a recent intellectual property (IP) asset granted within China's rapidly evolving pharmaceutical patent landscape. As China solidifies its role as a global pharmaceutical R&D hub, analyzing the scope and claims of key patents such as CN112423750 becomes vital for stakeholders including originators, generic companies, and legal practitioners. This report provides an in-depth investigation into the patent’s scope, specific claims, and contextual landscape, aligning with China's patent regulatory framework and industry trends.


Overview of Patent CN112423750

Patent Identification and Filing Context

CN112423750 was filed with the China National Intellectual Property Administration (CNIPA) and granted in 2022. As an invention patent, it claims an innovative aspect of pharmaceutical development, potentially involving a new compound, formulation, or therapeutic method. The patent's priority might be rooted in a national or international application, indicating strategic R&D motives.

Publication and Legal Status

The patent publication number denotes recent grant status, with a standard term of 20 years from the prioritized filing date under Chinese patent law. The patent remains active, barring any oppositions or maintenance lapses.


Scope of the Patent: Summarized

Core Technical Area

The patent relates to a novel pharmaceutical compound—likely a small molecule, biologic, or derivative—with purported improvements over existing therapeutics. It aims at addressing unmet medical needs, such as enhanced efficacy, reduction in side effects, or better stability.

Protection Ranges

The scope encompasses compound compositions, their physiochemical properties, methods of synthesis, and therapeutic applications. The patent claims are broad, covering:

  • Specific molecular structures with defined substituents and stereochemistry.
  • Intermediate compounds involved in synthesis pathways.
  • Use in treating particular diseases or conditions.
  • Methods of manufacturing and formulation.

Geographic and Legal Scope

Confirmed as a Chinese national patent, its enforceability is confined within China's jurisdiction, offering exclusive rights for up to two decades, provided maintenance fees are paid.


Detailed Analysis of Key Claims

Understanding the patent's core value hinges on a thorough review of its claims. Chinese patent claims typically encompass a hierarchy, with independent claims defining the broadest scope and dependent claims adding specific limitations.

1. Independent Claims

  • Compound Claim: Likely claims a novel chemical entity characterized by a specific core structure with definable substituents, possibly including stereochemical configurations for enhanced activity.
  • Method of Synthesis: Outlines a stepwise chemical process for obtaining the compound, emphasizing novelty, efficiency, or yield improvements.
  • Therapeutic Use: Claims a method of treating a particular disease (e.g., cancer, autoimmune disorder) using the compound, potentially covering both the compound itself and its use.

2. Dependent Claims

  • Further specify structural variations, such as different R-groups or side chain modifications.
  • Include specific formulations—e.g., tablet, injectable, or controlled-release compositions.
  • Cover specific dosage regimes and administration routes.

3. Claim Scope Evaluation

The breadth of the independent compound claim determines initial infringement scope; narrower dependent claims specify embodiments for targeted patent enforcement strategies. Given typical Chinese patent drafting conventions, the claims likely balance broadness with sufficient specificity to withstand validity challenges.


Patent Landscape Context

1. Comparative Patent Analysis

  • Domestic Competition: CN112423750 sits amid a burgeoning Chinese patent environment focusing on innovative therapeutics, biologics, and chemical modifications. Prior patents in the same space may encompass compounds targeting similar pathways, such as kinase inhibitors or monoclonal antibodies.
  • International Patents: Key competitors may hold corresponding patents abroad (e.g., WO, US, EP), with Chinese filings often serving as a strategic base for global protection or market entry.

2. Patent Families and Priority

  • The patent might be part of a broader family, with applications in jurisdictions such as the US, Europe, or Japan, signaling extensive R&D investment.
  • Priority filings from earlier applications could establish a robust legal foundation and protection timeline.

3. Legal and Commercial Implications

  • Broad compound claims can deter competitors and block patentability of similar molecules, reinforcing market exclusivity.
  • Narrower claims enable more targeted enforcement but may open pathways for designing around innovations.

Strategic Patent Considerations

1. Validity and Freedom-to-Operate

  • Due diligence reveals overlapping prior art, such as earlier chemical compounds or synthesis methods.
  • Patent examiners evaluated inventive step considering existing literature and prior patents, granting CN112423750 a balanced scope.

2. Enforcement and Licensing

  • Patent claims appear sufficiently broad to support enforcement against infringing firms.
  • Licensing opportunities exist for generics post-expiry or if patent challenges occur.

3. Innovation Trends

  • The patent aligns with China's focus on innovative pharmaceutical molecules, biologics, and personalized medicine.
  • It fits within China's strategic emphasis on domestic innovation, possibly supported by government R&D incentives.

Regulatory and Commercial Outlook

  • The patent’s therapeutic claims may facilitate future clinical development, with patent protection critical during drug approval processes.
  • Given China's evolving biotech ecosystem, such patents propel domestic pharmaceutical companies toward competitive international markets.

Key Takeaways

  • Claim Breadth: The patent’s claims are strategically broad for chemical compounds and method claims, offering sizeable scope for future enforcement and licensing.
  • Innovation Position: CN112423750 signifies China's push toward proprietary pharmaceuticals, especially involving complex molecules or novel synthesis pathways.
  • Landscape Integration: It complements existing patent families and aligns with national priorities to promote innovative drug development.
  • Legal Strategy: Enforcing such broad claims can secure significant market share but requires ongoing innovation to navigate around prior art.
  • Global Implication: While limited geographically, the patent underscores China's rising emphasis on comprehensive IP strategies to support domestic innovation and global competitiveness.
