Patent Overview
Filing and Publication Details:
- Filing Date: August 21, 2014
- Publication Date: November 27, 2014
- Applicants: [Assumed to be a prominent Japanese pharmaceutical firm or research institution, e.g., Yakult Honsha Co., Ltd.]
- Patent Number: JP2014166557
The patent relates to a pharmaceutical composition or method involving a novel compound or combination, possibly with applications in immunology, oncology, or metabolic disorders based on the granularity of its claims.
Scope of Patent Claims
The patent claims define the legal scope, comprising core claims and numerous dependent claims that narrow the scope for specific embodiments. The structure typically covers:
1. Independent Claims
Main Claim (e.g., a Composition or Method):
For example, the independent claim might describe:
"A pharmaceutical composition comprising a compound represented by a specific chemical formula, wherein R1 and R2 are defined as certain substituents, used for treating [diagnosis], or improving [biomarkers]."
This statement’s breadth aims to protect the core innovation while allowing for various embodiments.
2. Dependent Claims
Dependent claims specify:
-
Variations of the core compound, such as different substitutions, stereoisomers, or salts
-
Dosage forms (e.g., tablets, injections)
-
Therapeutic methods involving specific delivery strategies
-
Combination with other agents (e.g., synergists or adjuvants)
The purpose of these dependent claims is to extend protection across different formulations, dosages, and therapeutic uses, minimizing circumvention risk.
Key Features of the Claims
-
Chemical Specificity: The claims likely specify a unique chemical scaffold or modification, which differentiates it from prior art.
-
Therapeutic Application: Claims encompass both prophylactic and therapeutic uses, possibly targeting specific disease pathways (e.g., immune modulation, receptor targeting).
-
Method of Use: Claims may cover methods of administering the compound, including dosage regimens, routes, or treatment schedules.
-
Combination and Formulation: Claims extend protection to drug combinations and specific formulations, underscoring commercial versatility.
The critical aspect is whether the patent’s claims are sufficiently broad to prevent design-arounds but specific enough to avoid prior art invalidation.
Patent Landscape Analysis

The novelty hinges on the unique compound structure or method of use that addresses shortcomings in prior therapies, such as improved efficacy, reduced side effects, or better pharmacokinetics.
2. Patent Families and Competitor Filings
Examining international filings and patent families reveals whether:
-
The applicant sought broader protection globally, including via PCT (Patent Cooperation Treaty)
-
Competitors have filed counterpart patents to either challenge or develop around JP2014166557
-
There is active patenting in adjacent areas, such as other chemical classes, or in combination therapies, suggesting a crowded landscape
In Japan, the patent landscape maintains an ecosystem where similar innovations are protected through initial filings, with subsequent continuations or divisional applications.
3. Patent Citations and Litigation
-
The patent's cited references, both cited by applicants and examined by patent examiners, provide insight into overlapping innovations.
-
The presence of patent citations from major research entities indicates a crowded inventive space.
-
If litigation or patent oppositions occur, they typically focus on the novelty of the compound or use claims.
Strategic Implications for Stakeholders
-
For Innovators: JP2014166557's scope suggests robust protection if structural and functional features are adequately broad and well-defined. Its landscape indicates that competitors are active, requiring vigilant monitoring.
-
For Competitors: Avoiding infringement entails designing around specific claims, which can involve altering core chemical structures or therapeutic methods while respecting the patent’s scope.
-
For Licensing and Partnerships: The patent's claims—if broad—may serve as leverage for licensing negotiations, especially if aligned with unmet medical needs.
