Scope of Patent JP2021530544
Technological Field
JP2021530544 belongs to the field of medicinal chemistry, specifically concerning the synthesis, use, and therapeutic application of novel small molecules. The patent emphasizes compounds with specific structural features designed to modulate biological targets implicated in disease pathways.
Intended Therapeutic Applications
Although the patent’s broad language covers various uses, it explicitly mentions applications in treating neurological disorders, such as Alzheimer's disease, Parkinson's disease, or certain cancers, including lung or breast carcinomas. The scope also encompasses the use of these compounds as intermediates or precursors in pharmaceutical formulations.
Legal Boundaries
The patent applies to:
- The chemical compounds as described, with defined structural formulae.
- Methods for synthesizing these compounds.
- Uses in treating diseases as described.
- Pharmaceutical compositions containing the compounds.
- Methods of administering these compounds for therapeutic purposes.
This broad coverage allows the patent to extend protection across multiple facets of the invention, from chemical structure to therapeutic use.
Claims Analysis
Claim Hierarchy & Breadth
The patent's claims are structured hierarchically, with independent claims covering the core compounds and their pharmaceutical uses, followed by multiple dependent claims specifying particular chemical variants, formulations, and treatment methods.
Key Independent Claims
-
Chemical Structure Claims: The primary independent claim defines a class of compounds characterized by a core heterocyclic scaffold with specific substituents. These compounds are designed to bind to certain biological targets, such as enzymes or receptors involved in disease pathology.
-
Use Claims: The patent broadly claims the use of these compounds in preventing or treating neurological or oncological diseases, provided the compounds meet the structural criteria outlined.
-
Manufacturing Method Claims: Method claims covering the synthesis routes for preparing the compounds, including reagents, catalysts, and reaction conditions.
Dependent Claims
The dependent claims specify preferred embodiments, such as specific substituent groups (e.g., methyl, hydroxyl, fluoro), particular stereochemistry, or specific dosage forms. These narrower claims serve to bolster patent robustness against potential challenges.
Claim Scope and Patentability
The claims are carefully drafted to balance breadth and specificity. The chemical claims are broad enough to cover a substantial chemical class, while the use claims focus on specific therapeutic indications, aligning with patentability criteria of novelty and inventive step. The broad structural claims could cover a significant library of compounds, potentially offering extensive market protection.
Patent Landscape Analysis
Global Patent Filings and Priority
- Priority Applications: The patent claims priority from earlier filings in the United States and Europe, providing extended territorial coverage.
- International Filings: Similar applications are filed under the Patent Cooperation Treaty (PCT), indicating strategic efforts toward global patent protection.
Competitive Landscape
The chemical space targeted by JP2021530544 overlaps with existing patent families owned by major pharmaceutical companies focusing on neuroprotective and anticancer agents. Notable patent family members in the U.S., Europe, and China reveal active competition, which could influence freedom-to-operate (FTO) assessments.
Patent Families and Related Applications
The patent family linked to JP2021530544 includes counterparts with overlapping claims, refining scope to cover various pharmacological activities and formulations. These counterparts may also have different claim strategies to secure expansive protection or narrow, enforceable rights in key jurisdictions.
Prior Art and Novelty
Analysis indicates the compounds claimed are distinct in their specific heterocyclic substitutions compared to earlier patents. The inventive step is supported by biological data demonstrating improved efficacy or reduced toxicity, which are often critical in defending validity and patentability.
