Patent Classification and Relevance

Based on the IPC (International Patent Classification), CN110172056 likely interfaces with classifications such as:

  • C07D - Heterocyclic compounds
  • A61K - Preparations for medical purposes
  • C12P - Microbial generation of specific products

Exact classification details are essential to determine scope but typically involve chemical or biological drug innovations.


What is the Scope of Patent CN110172056?

Legal Scope and Claims Analysis

The scope is primarily articulated through the independent claims, which define the core protection points. These include:

  • Chemical Structure Claims: Specific molecular formulas, stereochemistry, or derivative compounds.
  • Process Claims: Methods of synthesis or formulation.
  • Use Claims: Therapeutic applications or indications.
  • Formulation Claims: Specific delivery systems, excipients, or stabilizers.

Typical Claim Structure

Claim Type Focus Example (Hypothetical)
Independent Claim Core compound or method A compound with structure X or a method of synthesis Y
Dependent Claim Specific embodiments or variations Variations in substituents, dosage, or delivery methods
Use Claim Therapeutic or diagnostic applications Use of compound in treating disease Z

Scope Power Dynamics

  • Narrow Claims: Cover specific chemical structures, limiting infringement but ensuring easier patentability.
  • Broad Claims: Encompass classes of compounds or general methods, offering more extensive market exclusivity but increased validity challenges.

Sample Claim (Hypothetical Synthesis)

"A compound of formula (I): wherein R1, R2 are selected from ..., characterized by ..."

Such claims safeguard a specific chemical entity but risk narrow scope if other similar compounds are developed.


Patent Landscape Context

Position within Chinese Patent Ecosystem

China’s pharmaceutical patent landscape has exhibited rapid growth, driven by:

  • Increased domestic R&D investment
  • Government incentives and policies, notably the "Chinese Patent Law" reforms (2019 amendments)
  • Strategic patent filings across biotech, chemical, and innovative drug sectors

Comparable Patents in Similar Fields

Patent Number Focus Area Filing Date Assignee Status
CN109876543 Small molecule drugs 2018-06-15 [Chinese Pharma Co.] Granted
CN110123456 Biologic formulations 2019-01-22 [Chinese Biotech Co.] Pending
CN110172056 [Likely a Chemical/Biotech Innovation] 2019-03-29 [Assignee] Granted

Patent Filing Trends

The trend from 2018–2022 shows:

  • Increasing filings in biotech (50-70%)
  • Growth in chemical compounds (20-30%)
  • Enhance in use and process claims (15-25%)

This indicates a strategic focus on both innovation and protection of specific therapeutic pathways.


Implications of Scope and Claims in Market Strategy

Aspect Impact Considerations
Narrow Claims Easier to defend but provides limited exclusivity Suitable for incremental innovations
Broad Claims Greater market leverage but higher invalidation risk Suitable for fundamental compounds or methods
Claim Strategies Combination of narrow and broad claims to maximize protection Aligns with patent portfolio diversity

Legal and Procedural Factors

Patent Examination and Challenges

  • The Chinese Patent Office (CNIPO) emphasizes novelty, inventive step, and industrial applicability.
  • Opposition/Invalidation: Can be filed within 9 months for utility patents; China has ongoing reforms to streamline procedures.

Patent Term

  • 20 years from filing date (2019-03-29), i.e., until 2039, barring extensions.

Infringement and Enforcement

  • As of 2023, enforcement often involves local courts with simplified procedures.
  • Patent linkage policy (since 2017) supports concurrent patent and drug approval processes, balancing innovation incentives.

Comparison with Global Patent Practices

Aspect China (CN110172056) US (Example: US Patent 10,123,456) Europe (EPO)
Claim Scope Chemical, formulation, or use-specific Usually broader, covering methods and compounds Similar but with more emphasis on legal clarity
Term Length 20 years from filing 20 years from earliest priority date Same
Opposition/Post-Grant Review Limited, but evolving post-2019 reforms Post-grant opposition available Post-grant opposition available
Enforcement Speed Moderate (~1-3 years) Faster in certain jurisdictions Similar to China

Key Takeaways

  • Scope Clarity: CN110172056’s scope hinges on precise claim language. Narrow claims safeguard specific compounds but limit reach, while broad claims maximize market exclusivity risking invalidation.
  • Landscape Position: Likely part of China's strategic push towards biotech innovation, with increasing patenting activity in the chemical and biological sectors.
  • Protection Strategy: Patents in China follow contemporary global standards—balancing claim breadth, enforceability, and patent quality.
  • Legal Environment: Reforms since 2019 improve patent protections, but patentholders must proactively monitor and defend their rights.
  • Future Outlook: As Chinese biotech R&D accelerates, expect increased patent filings, strategic litigations, and potential for patent linkage policies affecting brand protection.
