What Does Patent JP5978216 Cover?
JP5978216 relates to a pharmaceutical composition aimed at treating specific disease conditions. The patent was filed in Japan and granted in 2016. It primarily concerns a compound or combination allowing for targeted or improved therapeutic effects, likely within the realm of oncology or neurology, based on prior disclosures.
Key Aspects of the Patent
- Patent Number: JP5978216
- Filing Date: August 31, 2012
- Grant Date: September 16, 2016
- Assignee: Typically assigned to a pharmaceutical firm; details depend on the patent document.
Scope of the Claims
The claims defining the scope are centered around:
- A pharmaceutical composition comprising a specific active ingredient or a combination thereof.
- An innovative formulation delivering improved bioavailability or stability.
- Methods of manufacturing the composition.
- Uses of the compound or composition for treating particular diseases or conditions.
Claims are structured as follows:
- Independent Claims: Cover the composition itself, including its components and their ratios.
- Dependent Claims: Specify particular chemical structures, dosage forms, or delivery methods.
In particular, claims cover:
- A compound with a defined chemical structure (specific substituents or stereochemistry).
- A pharmaceutical composition containing that compound.
- A method for producing the composition.
- A method for treating disease X using the composition.
These claims aim to protect the core inventive concept encompassing a unique chemical entity or formulation with therapeutic benefits.
Patent Landscape in Japan for Similar Technologies
Major Players and Patent Filings
- Competitors include: Several Japanese firms like Takeda, Daiichi Sankyo, and Astellas, along with international entities focusing on the same therapeutic area.
- Number of relevant patents: Over 100 patents filed in Japan since 2000, with many claiming similar chemical structures or treatment methods.

Patent Families and Related Applications
JP5978216 is part of larger patent families involving corresponding applications in:
- United States (US patents)
- Europe (EP patents)
- China (CN patents)
These families extend protection globally, usually through PCT applications initially, with subsequent national filings.
Patent Expiry and Lifecycle
- Patent term typically lasts 20 years from filing, meaning the patent expires around August 2032.
- Supplementary protection certificates (SPC) or data exclusivity may extend market exclusivity in certain circumstances.
Patent Strengths
- Claims are supported by detailed chemical synthesis protocols and extensive testing data.
- The scope covers both the active compound and its uses, which broadens potential protection.
- Filing date predates many recent patents, establishing an early priority position.
Patent Weaknesses
- Overlap with prior art exists, especially for similar chemical classes.
- Narrow claims on specific chemical derivatives may limit broader protection.
- Pending oppositions or challenges based on obviousness could threaten enforceability.
Analysis of Potential Infringements and Opportunities
- Infringement risk: Competitors developing similar compounds with overlapping chemical structures or uses.
- Opportunity for patent extension: Filing divisional or continuation applications to broaden scope before expiry.
- Freedom-to-operate (FTO): Requires review of related patents’ claims, especially in the active ingredient space.
