Analysis of Patent JP6265964: Scope, Claims, and Landscape

Last updated: February 27, 2026

What is the scope and core claims of Patent JP6265964?

Patent JP6265964 covers a pharmaceutical composition aimed at treating or preventing diseases associated with protein aggregation, such as neurodegenerative disorders. The patent claims focus predominantly on compounds, compositions, and methods related to inhibiting or reducing protein aggregation.

Key Claim Categories

  • Chemical Compounds: The patent claims specific class of compounds, emphasizing small molecules with particular structural features conducive to inhibiting protein aggregation.
  • Pharmaceutical Formulations: Claims extend to pharmaceutical compositions containing these compounds, optionally combined with carriers or excipients.
  • Methods of Use: The patent includes claims covering methods for preventing or treating diseases like Alzheimer's disease, Parkinson's, and other neurodegenerative conditions by administering these compounds.

Notable Claims

  • Claim 1: A compound with a specific chemical structure described by the patent's formula, which exhibits activity in inhibiting amyloid or alpha-synuclein aggregation.
  • Claim 2: Pharmaceutical compositions containing at least one compound as described in Claim 1, combined with pharmaceutically acceptable carriers.
  • Claim 3: Method of inhibiting protein aggregation in a subject by administering an effective amount of the claimed compound.
  • Claim 4: Use of the compound for manufacturing a medicament for treating neurodegenerative diseases characterized by abnormal protein aggregation.

Claim Limitations

The scope is constrained to compounds meeting the structural criteria outlined, with supplementary considerations for dosage, administration route, and treatment timing. It emphasizes the activity against specific pathological proteins, limiting broader claims beyond the described chemical structures and applications.

FAQs

1. Can I develop a drug using compounds outside the scope of JP6265964?
Yes. The patent claims specific chemical structures. Compounds outside these structures or with different mechanisms may avoid infringement.

2. How long is the patent protection for JP6265964?
Typically, Japanese patents expire 20 years from the filing date, which in this case is May 27, 2019. Patent expiry is expected around May 27, 2039.

3. Are there any infringement risks associated with similar compounds?
Potentially, especially with patents covering similar heteroaromatic compounds or aggregation inhibitors. A freedom-to-operate analysis is advised.

4. What are the competitive advantages of this patent?
The patent claims specific compounds with demonstrated activity against disease-associated protein aggregation, offering a legal barrier to competitors.

5. Is the patent enforceable outside Japan?
Enforceability depends on corresponding patents in other jurisdictions. The patent family includes filings in China and the U.S., offering broader territorial protection if granted.
