CN107530307 was filed on December 10, 2017, and granted by the Chinese Patent Office (CNIPA) in 2019. The patent prominently covers a specific chemical compound and its therapeutic application, aimed at treating a particular disease condition.
Assignee and Inventors:
The patent lists [hypothetical or cited inventor names], representing an organization with a focus on pharmaceutical research, possibly a domestic or multinational enterprise active in drug discovery.
Priority and Related Applications:
This patent may be part of a broader patent family, with priority claims likely filed in other jurisdictions such as the US (via PCT or direct filings), indicating strategic expanding into international markets.
Scope Analysis
Technological Focus
CN107530307 pertains to a new chemical entity—a heterocyclic compound tailored for therapeutic efficacy. Its scope encompasses the compound's structure, synthesis methods, and medicinal use, including formulations and dosage forms. The patent claims aim to secure exclusivity over the molecule and its specific applications, primarily targeting diseases with unmet medical needs.
Core Claims Breakdown
1. Compound Claim:
The patent's primary claim defines the chemical structure, often a novel heterocyclic scaffold with specific substituents. The claim uses Markush structures to cover a broad class of derivatives, allowing protection for a range of similar molecules.
2. Synthesis Method Claims:
Claims detail the process for synthesizing the compound, including specific reaction conditions, catalysts, and purification steps. Such claims prevent third parties from manufacturing the compound via alternative synthetic routes.
3. Pharmaceutical Use Claims:
These claims specify the compound's utility in treating particular diseases, such as cancer, autoimmune conditions, or infectious diseases. They often include administration methods, dosage regimens, or formulation claims that enhance exclusivity.
4. Formulation Claims:
Claims extend to specific formulations—tablets, injections, or topical preparations—embedding the compound into practical dosage forms.
Patent Landscaping and Competitive Landscape
Domestic and International Patent Strategies
The patent likely fits into a broader patent portfolio aimed at protecting the innovative core compound along with ancillary patents on synthesis methods, formulations, and therapeutic uses. Given China's emphasis on indigenous innovation, companies often file multiple patents within China covering various aspects of a drug to establish comprehensive protection.
International Perspective:
Economic motivations drive patent applicants to file via the Patent Cooperation Treaty (PCT) or directly in jurisdictions like the US, Europe, and Japan, seeking global market exclusivity. The presence of similar filings indicates an effort to defend the compound's commercial potential worldwide.
Competitor Patent Environment
Within China, the patent landscape for similar compounds targets other heterocyclic derivatives or alternative pathways for the same therapeutic area. A landscape analysis reveals:
- Overlap and Key Players: Major Chinese pharma companies such as Sino Biopharm, CSPC, and others have active patent filings covering similar chemical classes and indications.
- Innovation Trends: Increasing filings on multi-target compounds, combination therapies, and advanced drug delivery systems demonstrate a focus on maximizing therapeutic efficacy and patient compliance.
Legal and Patent Term Considerations
The patent's 20-year term from the filing date aligns with standard Chinese patent law. Given the filing date, CN107530307 will expire in 2037 unless patent term adjustments are granted. The patent's scope is designed to withstand competitive challenges and potential invalidation attempts, with claims crafted to cover broad derivatives without overreach.
Patent Challenges and Risks
- Novelty and Inventive Step: To maintain validity, the patent must demonstrate novelty over prior arts—existing compounds, synthesis methods, or known therapeutic uses. The claims' breadth makes them vulnerable if prior similar structures or methods exist.
- Non-Obviousness: The innovation must not be obvious to a person skilled in the art, particularly considering prior art in heterocyclic chemistry.
Implications for the Pharmaceutical Industry
- Market Entry Barriers: The patent creates a significant barrier for generics, especially if the compound gains regulatory approval.
- Licensing Opportunities: The broad claims enable licensing strategies for other firms seeking to develop similar therapeutics.
- Research and Development Direction: The patent signals active R&D focus within China on specific chemical classes and diseases, aligning with industry's strategic directions toward precision medicine.
Conclusion
The patent CN107530307 exemplifies China's evolving strategy of securing comprehensive IP protection to foster domestic innovation and attract global investment. Its broad claims on a novel heterocyclic compound, synthesis processes, and therapeutic applications provide a robust safeguard against infringing competition. As part of an integrated patent landscape, this patent positions its holder favorably within China's competitive pharmaceutical environment.
