Overview of Patent JP2017080424
Publication Details:
- Publication Number: JP2017080424
- Application Date: Likely filed in 2016 or early 2017 based on publication date, considering JP publication timelines.
- Inventor/Applicant: [Typically, major Japanese pharmaceutical companies or academic institutions are involved; specifics vary based on the actual patent document.]
Subject Matter:
While the precise details depend on the actual patent text, Japanese patent documents with similar numbering commonly relate to novel drug formulations, intermediates, or methods of preparation/design of therapeutic compounds.
Assumed Focus:
Given the nature of many recently published Japanese pharmaceutical patents, JP2017080424 is presumed to be directed towards:
- A novel pharmaceutical compound or a therapeutic method
- A unique dosage form or drug delivery system
- A stable formulation or a process for manufacturing the same
For this analysis, we assume the patent covers a novel pharmaceutical composition involving a specific active ingredient with enhanced bioavailability or stability.
Scope of the Patent:
The scope of JP2017080424 hinges primarily on its claims, delineating the inventive boundaries.
Claims Overview:
-
Independent Claims:
These define the core invention, typically encompassing the novel compound, formulation, or method. For example, an independent claim might specify:
- A pharmaceutical composition comprising an active ingredient X combined with a specific carrier or excipient Y, wherein the composition exhibits enhanced stability or bioavailability.
- A method of manufacturing the composition utilizing a particular process or apparatus.
-
Dependent Claims:
These specify preferred embodiments, additional features, or specific parameter ranges—such as concentration, particle size, or pH conditions.
Scope Analysis:
- The claims likely use open, functional language (e.g., “comprising,” “consisting essentially of”) permitting some flexibility.
- The core claims probably focus on the composite formulation or method for preparation rather than the compound alone, aligning with strategic approaches designed to extend patent lifespan and coverage.
- The presence of secondary claims covering variations (e.g., different excipients, dosages, or administration routes) broadens the patent's scope, providing defensibility against design-arounds.
Limitations:
- The scope may be limited by prior art references, especially in areas like drug delivery systems or formulation strategies.
- If the claims focus narrowly on a specific combination or process, the coverage might be susceptible to invalidation by prior arts that disclose similar compositions or methods.
Patent Claims Analysis
Claim Structure:
Claims Robustness:
- The broader claims may be vulnerable to prior art, especially if similar formulations exist.
- Narrower claims, such as specific chemical structures or process parameters, are more defensible.
Implications for Patent Erosion or Infringement:
- Competitors attempting to develop similar formulations need to avoid infringement of the core claims.
- The scope allows for potential licensing or cross-licensing opportunities in related formulations or methods.
Patent Landscape Context in Japan
Japanese Pharmaceutical Patent Environment:
- Japan is a leading innovator in pharmaceuticals, with a mature patent system emphasizing high validation standards.
- Post-G MEC (Medicine and Medical Devices Act) reforms, there has been increased emphasis on patent quality and litigation potential.
Major Patent Prior Art:
- Similar patents in Japan often cite:
- Japanese Patent Applications (JP-A) in related formulation areas.
- International applications (PCT WO publications) with priority claims to the same invention.
- Pre-existing patents on comparable chemical entities, delivery systems, or manufacturing processes.
Competitive Landscape:
- Large Japanese pharma firms such as Takeda, Astellas, Daiichi Sankyo, and pharmaceutical divisions of multinational corporations actively file and litigate patents involving complex formulations and biologics.
- The patent landscape is characterized by:
- Strategic patent families covering multiple aspects of a novel drug.
- Evergreening tactics involving process patents or incremental improvements.
- Patent challenges, including pre- and post-grant invalidation procedures.
Legal Status and Enforcement:
- The patent's enforceability depends on its grant status and opposition background.
- Japan’s courts actively uphold patent rights, with recent trends favoring patentees in infringement disputes involving pharmaceuticals.
Fit within the Broader Patent Landscape
- JP2017080424 complements or overlaps with other patents in the same class (e.g., drugs for specific indications, formulations involving similar excipients or delivery systems).
- It potentially forms part of a patent portfolio aimed at securing comprehensive protection around a blockbuster drug or a novel therapeutic approach.
- Its positioning may influence licensing negotiations, partnership deal structures, or competitive entry strategies.
