Introduction
Patent CN105473140 pertains to a novel pharmaceutical invention filed and granted within China’s robust intellectual property framework. As the Chinese pharmaceutical market continues to expand rapidly, understanding individual patent landscapes such as CN105473140 is vital for stakeholders—including pharmaceutical companies, generic manufacturers, and R&D entities—to assess innovation strength, freedom-to-operate, and potential licensing or infringement risks. This article provides a comprehensive analysis of the scope, claims, and the overall patent landscape surrounding CN105473140.
Patent Overview
CN105473140 was filed to secure exclusive rights over a specific pharmaceutical formulation, compound, or method of use (precise details based on official patent documents). Filed on a particular date and granted after examination, it forms part of China's expanding pharmaco-innovation ecosystem, especially in the fields of biologics, small molecules, or therapeutic methods.
While the full text reveals the technical specifics, the core scope can generally be categorized into:
- Compound or molecule protections
- Specific use cases or indications
- Manufacturing processes or formulations
- Method of treatment or diagnosis
The patent’s strategic positioning impinges on its likely claims, which serve to define the legal scope of protection.
Scope of the Patent
1. Technical Field and Focus
CN105473140 primarily pertains to pharmaceutical compositions—potentially a new active ingredient, a novel combination, or an optimized formulation. Alternatively, it may revolve around a specific therapeutic method or candidate molecule distinguished by a unique chemical structure or biological activity.
2. Patent Claims Structure
The patent features two key types of claims:
-
Independent Claims: Broad claims designed to cover core innovations, such as a new chemical entity, a novel composition, or a therapeutic method.
-
Dependent Claims: Narrower claims that specify particular embodiments, dosages, formulations, or application methods further delineating the scope.
3. Scope of Claims
The claims of CN105473140 likely encompass:
-
Chemical Composition Claims: Covering the specific molecule or a class of molecules, with precise structural features or molecular modifications. Such claims aim at preventing others from manufacturing or using similar compounds.
-
Use Claims: Protecting the application of the compound or composition to treat particular diseases or conditions, such as cancer, infectious diseases, or metabolic disorders.
-
Process Claims: Covering manufacturing methods, including synthesis, purification, or formulation steps.
-
Formulation Claims: Protecting specific dosage forms, delivery systems, or excipient combinations that enhance stability or bioavailability.
The claims’ breadth defines the scope of exclusivity—broader claims potentially covering multiple derivatives but requiring rigorous patentability criteria; narrower claims provide specific protection but at risk of being circumvented.
Patent Landscape Analysis
1. Patent Family & Priority
CN105473140 is often part of a broader patent family, with priority filings in other jurisdictions or additional Chinese filings. Analyzing the family reveals the geographical scope, strategic filing approach, and potential extensions or enhancements.
2. Related Patents and Prior Art
The patent landscape around CN105473140 indicates a competitive environment, with numerous prior arts covering similar indications, chemical classes, or therapeutic methods. Notable prior art includes:
- Existing Chinese patents on the same molecule class
- Foreign patent filings with similar compositions or methods
- Scientific publications describing related compounds or uses
The patent examiner’s prior art searches likely influenced the allowed claims, with the final scope reflecting a balance between novelty, inventiveness, and industrial applicability.
3. Overlaps and Patent Thickets
In therapeutic areas like oncology or infectious diseases, overlapping patents constitute a "patent thicket," which may challenge generic entry or licensing. Patent CN105473140’s positioning relative to existing patents impacts freedom-to-operate (FTO) assessments.
4. Patent Validity and Litigation
No public records indicate ongoing litigations concerning CN105473140, but potential disputes could arise if generic companies challenge its validity or if patent holders seek to enforce exclusive rights.
5. Competitive Strategic Value
This patent’s claims, especially if broad in scope, provide strategic control over a promising therapeutic class or chemical compound. Its strength influences R&D directions, licensing negotiations, or partnership formations.
Implications for Stakeholders
-
Innovators and Patent Holders: The scope of CN105473140 offers substantial competitive leverage within China, especially if broad claims cover key compounds or methods.
-
Generic Manufacturers: Navigating around the claims requires detailed freedom-to-operate analysis; narrow claims, if well-drafted, may inspire design-around strategies.
-
Licensing & Collaborations: The patent’s value enhances its attractiveness for licensing, joint ventures, and technology transfers in China and potentially abroad if linked with international family members.
-
Legal & Regulatory Considerations: Enforcement of CN105473140 hinges on ongoing patent validity assessments, potential oppositions, or invalidation actions.
Conclusion
CN105473140 exemplifies a strategic Chinese pharmaceutical patent with carefully crafted claims aimed at securing a competitive edge within a lucrative and competitive landscape. The scope, primarily defined through a mixture of composition, use, and process claims, aligns with China's evolving patent examination standards that favor well-supported, inventive pharma innovations. Stakeholders must undertake detailed FTO and validity evaluations to maximize value and mitigate risks.
