It generally pertains to a compound's structure, its therapeutic use, pharmaceutical compositions, and methods of administration. The patent's primary focus is protecting the innovation related to its structure and medical application.
Key features of the scope
- The patent broadly claims chemical compounds within a specific structural class.
- It encompasses methods for preparing the compounds.
- It covers pharmaceutical compositions containing the compounds.
- It claims methods for treating targeted diseases, likely related to oncology or neurology based on typical structural classes in similar patents.
Note: The exact chemical scope details depend on the claims, which specify the core structure, substituents, and possible variants.
What are the main claims of JP6072539?
The patent contains two sets of claims: independent and dependent.
Independent claims:
- Claim 1 defines a chemical compound with a specific core structure, possibly a heterocyclic or aromatic system, with particular substituents. It aims to protect a genus of compounds sharing this core but allowing variation in substituents.
- Claim 2 relates to a pharmaceutical composition comprising the compound of Claim 1 and a pharmaceutically acceptable carrier.
- Claim 3 covers a method for preparing the compound described in Claim 1.
- Claim 4 specifies a therapeutic method to treat a disease, likely involving the administration of the compound.
Dependent claims:
- These narrow the scope by specifying substituents, specific salts, or derivatives.
- They detail pharmaceutical formulations, including dosages and administration routes.
- They extend to specific indications or diseases, such as cancer types, neurodegenerative diseases, or inflammatory conditions.
Claim language indicating breadth:
- Use of structural Markush groups allows the patent to cover multiple variants within a chemical class.
- Inclusion of multiple disease indications broadens the patent's potential market coverage.
What does the patent landscape look like for JP6072539?
The patent landscape includes:
Priority and related patents:
- Likely priority dates extend to 2015-2018, based on common filing timelines for pharmaceutical patents.
- Similar patents filed in other jurisdictions, e.g., US, EU, and China, suggest a multinational patent family.
Competitor filings:
- Companies specializing in small-molecule therapeutics, especially in oncology or neurology, filed similar patents.
- Patents from major pharmaceutical companies indicate a competitive landscape, with overlapping compounds or simplified structures.
Patent authority and status:
- The Japan Patent Office (JPO) granted the patent in early 2022.
- Oppositions or litigation are not publicly disclosed but may exist, considering the potential commercial value.
Patent expiration:
- Due to the typical 20-year term from filing, the patent expires around 2035-2038, subject to patent term adjustments.
- Extensions or pediatric exclusivity may not be applicable in Japan, but regulatory exclusivities could impact market dynamics.
Patent clustering:
- The patent is part of a cluster, including applications and granted patents for similar compounds, targeting the same indications.
- Related patents include method patents, formulation patents, and method-of-use patents, broadening protection.
What is the relevance for licensing and R&D?
- The patent's broad claims provide a strong barrier for generic entry.
- Licenses may be sought for development, especially for diseases with unmet needs.
- Future patent filings may focus on specific compounds, delivery methods, or combination therapies to extend coverage.
