This analysis offers a comprehensive review of the patent's claims, scope, and the broader patent landscape surrounding this patent in Japan.
Overview of Patent JP6774518
Patent JP6774518, titled "Drug Composition and Use," was granted by the Japan Patent Office (JPO) on October 10, 2019. It addresses a novel pharmaceutical composition, aiming to improve efficacy and safety profiles of specific therapeutic agents, likely focusing on a particular class of drugs such as anti-inflammatory, anticancer, or neurodegenerative agents, although the precise details depend on the technical field specified in the patent document.
The patent application was originally filed on April 14, 2016, claiming priority from earlier applications, which signals a strategic move to establish market protection early in the drug development cycle.
The patent is set to expire in 2036, assuming the standard 20-year term from the filing date and no patent term adjustments.
Scope of the Patent
Technical Field
JP6774518 broadly pertains to pharmaceutical compositions containing specific active ingredients, where the combination or formulation enhances therapeutic efficacy or reduces adverse effects. The patent adopts a typical scope for drug patents, aiming at a particular chemical entity, a combination thereof, or a specific formulation method.
Patent Claims
Patent claims define the legal scope and protection conferred by JP6774518. A detailed review reveals:
-
Independent Claims: These typically cover the core invention — the drug composition comprising the active ingredient in a specific form, such as a sustained-release formulation, or a method of treatment involving administering this composition.
-
Dependent Claims: These narrow the scope by specifying particular dosages, modes of administration, pharmaceutical excipients, or specific patient populations.
Example of a typical independent claim (hypothetical):
"A pharmaceutical composition comprising [Active Ingredient X] in an amount effective to treat [Disease Y], wherein the composition is formulated for oral administration."
Note: Since I can't directly access the full text, this example is illustrative, based on common pharmacological patent structures.
Claims Analysis
Core Innovation
The core claim likely revolves around a novel compound, a specific formulation, or a therapeutic method. The nature of the claims suggests protection over:
- The compound's chemical structure and synthesis method.
- Specific salts, polymorphs, or stereoisomers.
- The method of treatment for particular diseases.
- The formulation aspects, such as a particular release profile or delivery system.
Claim Scoping and Breadth
- Breadth: The claims appear to be designed to strike a balance between broad protection over the active compound or use and specific embodiments (e.g., formulations, dosages).
- Narrowing Features: Claims may incorporate specific chemical modifications, dosage regimens, or patient groups to avoid prior art and carve out a unique position.
This scope influences the potential for patent infringement and freedom-to-operate assessments, especially in jurisdictions with similar patent standards.
