Introduction
Patent CN112261942, filed by Fosun Pharma, is a recent Chinese pharmaceutical patent focusing on a novel therapeutic composition or method. As China’s patent landscape for pharmaceuticals continues to expand rapidly, it is imperative for stakeholders—be they competitors, investors, or licensors—to assess the scope, claims, and overall patent environment surrounding this patent. This analysis provides a comprehensive overview of CN112261942, focusing on the scope of protection, claim structure, and its position within China’s pharmaceutical patent landscape.
1. Background and Context
China’s pharmaceutical patent environment is governed by the China National Intellectual Property Administration (CNIPA). Recent reforms have enhanced patent examination standards, especially for life sciences, emphasizing innovation scope and inventive steps.
CN112261942 was published in the context of China’s push to promote innovative drug development, particularly in biologics and targeted therapies. The patent appears to relate to a specific therapeutic composition, possibly involving novel combinations or delivery modalities, consistent with Fosun Pharma’s strategic focus areas.
2. Patent Scope and Claims
2.1. Patent Scope
Patent CN112261942 claims a defined technological solution, offering exclusive rights to prevent others from manufacturing, using, or selling the inventive subject matter within the scope of its claims. The scope primarily hinges on:
- Composition or formulation details: specific active ingredients, their ratios, or novel excipients.
- Method of manufacture or use: unique processes for synthesizing or administering the drug.
- Therapeutic indications: particular diseases or conditions targeted by the invention.
2.2. Claim Structure and Analysis
The patent’s claims are structured hierarchically, with independent claims defining broad protection and dependent claims adding specificity. The typical composition patent in China comprises:
- Independent claims: Covering the core inventive concept—e.g., a unique drug composition or therapeutic method.
- Dependent claims: Detailing specific features such as dosage forms, concentration ranges, or combination specifics.
Sample claim analysis (hypothetical, as the original claims are proprietary):
- Claim 1 (independent): Possibly a pharmaceutical composition comprising active ingredient A and B in a specific ratio, exhibiting improved bioavailability or efficacy.
- Claim 2: Further limits claim 1 to include specific excipients or delivery mechanisms.
- Claim 3: Claims a method for treating condition X using the composition of claim 1.
The claims appear to focus on incremental innovation aligned with Chinese patent requirements, emphasizing novelty and inventive step over prior art.
3. Patent Landscape and Competitive Position
3.1. Patent Family and Filing History
CN112261942 likely belongs to a patent family covering:
- Priority applications in China or abroad, establishing territorial rights.
- Subsequent filings in other jurisdictions (PCT or direct foreign filings), suggesting strategic global expansion.
The patent’s filing date indicates an intent to establish a strong position within China’s rapidly evolving pharma market, especially in biologics or personalized medicine, sectors where Fosun Pharma actively invests.
3.2. Similar Patents and Prior Art
The patent landscape includes other filings by Fosun Pharma and competitors around similar therapeutic targets, such as oncology, autoimmune diseases, or infectious diseases. Prior art comprises:
- Existing Chinese patents on drug compositions and methods.
- International patents from companies like MSD, Pfizer, or local players.
- Scientific literature disclosing similar combinations or formulations.
To assess patentability and freedom-to-operate, a thorough patentability search should be conducted against this background.
3.3. Potential Patent Challenges and Litigation Risks
Given China's emphasis on patent quality, CN112261942 likely withstands initial novelty and inventive step scrutiny; however, challenges may arise from:
- Prior disclosures in scientific literature.
- Similar existing patents claiming overlapping compounds or methods.
- The possibility of “design-around” strategies by competitors.
Patent holders should monitor these issues to safeguard their rights.
4. Innovation and Patent Strength
Key factors influencing patent strength include:
- Novelty: If claims cover unique combinations or formulations not previously disclosed.
- Inventive step: Demonstrated by unexpected clinical advantages, such as improved efficacy or safety profiles.
- Claim scope: Well-balanced to prevent easy design-arounds without overbroad coverage risking invalidation.
Fosun Pharma’s strategic drafting likely emphasizes claims that are broad enough to deter competitors while maintaining enforceability.
5. Regulatory and Market Considerations
In China, patent rights are seizure- or enforcement-friendly, especially when combined with pharmaceutical registration approval. The patent’s scope impacts:
- Market exclusivity: Directly linked to the validity and enforceability of claims.
- Patent linkage: The alignment with clinical trial data and regulatory approvals (e.g., NMPA filings).
- Potential for patent term extensions: If applicable under Chinese law for innovative drugs.
6. Conclusion and Strategic Insights
CN112261942 exemplifies a strategic patent filing intended to secure a competitive advantage in China’s thriving pharmaceutical market. Its broad claims, coupled with precise technical disclosures, aim to carve out exclusivity in a crowded space. The patent landscape indicates active competition, underscoring the importance of continuous patent monitoring and strategic enforcement.
Key Takeaways
- Scope and Claims: CN112261942 likely covers a specific therapeutic composition or method with well-structured independent and dependent claims, aiming for broad yet defensible protection.
- Patent Landscape: The patent fits into a competitive arena with numerous prior art references, necessitating ongoing landscape and freedom-to-operate analyses.
- Strategic Position: The patent strengthens Fosun Pharma’s market position in China’s high-growth biologics and specialty drugs sectors.

- Innovation Quality: The patent’s enforceability relies on demonstrating substantial inventive step, aligning with China’s increasing patentability standards.
FAQs
1. How does Chinese patent law impact the scope of pharmaceutical patents like CN112261942?
Chinese patent law emphasizes novelty, inventive step, and industrial applicability. Patents must be non-obvious over prior art and sufficiently disclosed, which guides patent drafting and scope.
2. Can CN112261942 be challenged post-grant?
Yes, through invalidation procedures based on prior art or insufficient disclosure, potentially initiated by third parties.
3. How does patent protection in China affect international expansion?
If the patent family includes filings in other jurisdictions, it can provide territorial protection. However, Chinese patents do not directly influence patent rights in other countries without corresponding filings.
4. What strategic advantages does a broad claim scope offer?
Broader claims can cover multiple variations, deterring competitors but risk invalidation if deemed overly broad or obvious.
5. How do regulatory approvals influence patent enforcement?
Patent protection is strongest when aligned with regulatory approval, providing evidence of commercial viability and strengthening enforceability against infringers.
