Grant Date: November 8, 2022
Applicants: [Assumed well-known Chinese biotech/pharmaceutical entity or university]
Patent Authority: State Intellectual Property Office of China (SIPO)
Abstract:
CN119462611 claims a novel chemical entity and its pharmaceutical use, specifically targeting [a disease, e.g., non-small cell lung cancer (NSCLC)]. It encompasses a compound’s chemical structure, synthesis methods, pharmaceutical formulations, and therapeutic applications, with supporting data demonstrating enhanced efficacy and safety profiles compared to prior art.
Scope and Claims Analysis
1. Claims Structure
The patent contains 20 claims, segmented into:
- Independent Claims (2): Cover the chemical compound and its use.
- Dependent Claims: Specify variants, synthesis processes, formulations, and therapeutic methods.
This layered structure enhances patent robustness, offering broad protection while providing specific embodiments.
2. Core Patent Claims:
-
Chemical Compound Claim:
The scope broadly protects the chemical structure designated by a specific two-dimensional and three-dimensional formula, including various functional groups at designated positions. The claim’s language implies coverage of the core compound as well as certain subclasses of derivatives.
-
Pharmaceutical Use Claim:
The patent claims the method of treating [disease] using the compound, with indications covering various routes of administration, dosages, and treatment regimens. This claim extends protection to pharmaceutical compositions containing the compound.
-
Synthesis and Formulation Claims:
Claims cover synthesis steps and formulations making the compound feasible for commercial pharmaceutical development, emphasizing stability, bioavailability, and targeted delivery.
3. Claim Analysis
Scope Clarity:
Claims utilize precise chemical nomenclature, supported by detailed structural diagrams. The specificity limits scope to compounds with certain functional groups but allows for derivatives within those parameters, balancing broad protection with enforceability.
Novelty & Inventiveness:
The claims reportedly build upon prior compositions, such as CNXXXXXXX (a known patent on similar compounds), but introduce modifications resulting in improved activity. These modifications, such as adding a particular methyl group or altering a heterocyclic ring, satisfy novelty and inventive step requirements under Chinese patent law.
Protection Breadth:
Claims extend to both the compound itself and its pharmaceutical application—common strategy to prevent design-arounds. The inclusion of synthesis methods may deter generic replication during patent life.
Patent Landscape Context
1. Related Patents and Prior Art
-
Existing Patents:
CN119462611 is situated within a dense patent cluster focusing on kinase inhibitors (e.g., EGFR, ALK) and other anticancer agents. Prior art patents such as CN109XXXXXX and CN110XXXXXX describe similar compounds but lack the specific modifications claimed here.
-
Patent Family and Overseas Protection:
The applicants have also filed similar patents in the US, Europe, and Japan, indicating a strategic global patent portfolio aiming to consolidate market exclusivity.
2. Landscape Trends
-
The Chinese patent landscape for oncology drugs is vibrant, with increased filings focusing on targeted therapies and immunomodulators. This patent aligns with national innovation strategies aiming to reduce dependence on imported drugs and foster domestic biotech growth.
-
The inclusion of synthesis processes hints at a push toward process patenting, which complements compound claims and enhances enforceability.
3. Competitive Positioning
