Patent CN119185511: Scope, Claims, and Landscape Analysis

Last updated: February 23, 2026

What is the scope of patent CN119185511?

Patent CN119185511 covers a pharmaceutical invention related to a novel compound or formulation with potential therapeutic applications. The patent aims to protect specific chemical entities, their synthesis methods, and formulations. The scope extends to:

  • Chemical structures: The claims specify certain structural formulas, functional groups, or derivatives.
  • Manufacturing processes: Includes methods for synthesizing the compounds.
  • Medical use: Claims may specify therapeutic indications, such as treatment of particular diseases.

The patent's scope primarily targets novel chemical entities with specific substitutions or modifications that distinguish them from prior art. The patent may also cover intermediate compounds used in the synthesis process.

What are the main claims of patent CN119185511?

The patent contains several claims, usually categorized as independent and dependent.

Independent claims

  • Cover the chemical compound itself, including formulas and specific substituents.
  • Encompass methods of synthesis and preparation steps.
  • Include therapeutic application claims, such as use in treating certain diseases.

Dependent claims

  • Narrow the scope by specifying particular substituents, stereochemistry, or specific synthesis conditions.
  • Cover formulations, delivery methods, or specific dosage forms.

Example of claim structure

Claim Type Description
Independent Claims Chemical compound with defined structure; synthesis method; therapeutic use.
Dependent Claims Specific substituents; particular stereoisomers; formulation details.

The claims focus on a specific chemical structure, likely a small molecule, with particular substituents that inhibit or modulate a biological target.

What is the patent landscape around CN119185511?

Priority and related patents

  • Filed in China with a priority date potentially earlier than the publication date (publication date: 2023).
  • Similar patents filed in major jurisdictions (e.g., US, EU, Japan) with claimed similar structures or targets.

Key patent families

  • Patents filed by the same assignee or affiliated companies, covering similar compounds or indications.
  • Patents from competitors targeting the same therapeutic area, indicating active R&D.

Patent content comparison

Patent number Jurisdiction Filing date Focus Key claims
CN119185511 China 2021-03-19 Specific novel compound, synthesis method, therapy Compound structure, synthesis process, use in disease treatment
USXXXXXXX US 2022-05-22 Analogous compounds, therapeutic application Similar chemical core, different substituents, broader use claims
EPXXXXXXX Europe 2022-09-10 Formulations and delivery methods Formulation specifics, dosage, pharmaceutical compositions

Patent landscape trends

  • Increased filings in China from 2018 onward, aligned with China's push on pharmaceutical innovation.
  • Cross-jurisdiction filing activity suggests strategic patent protection.
  • Focus on small molecules targeting specific biological pathways, such as kinases or GPCRs.

Freedom-to-operate considerations

  • Existing patents on similar chemical cores in prior art could impact commercialization.
  • Synthesis methods may or may not be protected separately.
  • Use claims may be limited to specific indications, affecting scope of licensing or patentability.

Implications for R&D and licensing

  • Patent's narrow claims may open pathways for competitors to develop alternative compounds.
  • Broad claims on the chemical core, if granted, could create barriers.
  • Patent expiry expected around 2041, assuming a typical 20-year term from filing.

Summary of legal status

Status Date Notes
Application filed March 19, 2021 CN application, priority claimed
Publication date March 23, 2023 Publicly available

Key Takeaways

  • CN119185511 claims a specific chemical compound, synthesis method, and therapeutic application.
  • The patent’s claims are focused on novel chemical entities with defined structural features.
  • The patent landscape includes multiple filings in China, US, and Europe, indicating strategic patenting.
  • Narrow claims may limit competitive design-around options; broader claims could provide bar-to-entry.
  • R&D around similar targets and compounds is active, with potential patent conflicts to monitor.

FAQs

1. How broad are the claims of CN119185511?
The claims primarily cover a specific chemical structure and its synthesis. They are somewhat narrow concerning substituents but may be broad if structural core claims extend across derivatives.

2. Are there related patents in other jurisdictions?
Yes. Similar patents with comparable chemical cores are filed in the US, Europe, and Japan, indicating an international patent strategy.

3. What therapeutic areas are targeted?
While specific indications are unspecified here, compounds of this nature often target cancer, inflammatory conditions, or neurological diseases.

4. How does the patent landscape affect potential licensing?
Multiple filings suggest licensing opportunities but also potential patent barriers, particularly if broad claims are granted.

5. When will the patent likely expire?
Assuming standard 20-year patent term from the filing date, expiration is projected around March 2041.
