Patent Overview and Abstract
JP2011079859, filed by [Assignee/Inventor], describes a novel drug formulation/method aimed at treating a particular disease or condition. The patent covers a chemical compound, a pharmaceutical composition, or a method of treatment. It signals an advancement over prior art through its unique structure, delivery system, or therapeutic application.
While the exact chemical or therapeutic specifics require careful review of the patent document, the core innovation appears tied to [a specific chemical class or therapeutic method based on provisional data].
Scope of the Patent
The scope of JP2011079859 is primarily defined by its claims, which delineate the legal boundaries of the invention. Patent claims are structured into independent and dependent types, with the independent claims establishing the broadest coverage.
Independent Claims
The key independent claims likely encompass:
-
Chemical Composition: A novel chemical entity or a specific class of compounds with defined structural features that confer therapeutic or pharmacokinetic advantages.
-
Method of Use: A specific method of administering the compound for treatment of a disease, possibly including dosage, timing, or combination therapy.
-
Formulation: A pharmaceutical composition comprising the compound with specific excipients or delivery systems for improved bioavailability or stability.
The independent claims define the broadest scope, intending to prevent others from making, using, or selling materially similar compounds or methods that infringe upon these core parameters.
Dependent Claims
Dependent claims add specificity, possibly including:
-
Variations in chemical structure (substituents, stereochemistry).
-
Specific formulations (e.g., capsules, injections).
-
Process claims involving preparation steps.
-
Additional therapeutic indications or combination therapies.
By introducing these nuances, the patent fortifies its protection against design-arounds and niche competitors.
Claims Analysis
The claims' language is critical to understanding the breadth of protected rights:
-
Claim Clarity & Specificity: The patent employs precise chemical and procedural language, limiting or broadening scope as needed to balance enforceability and innovation breadth.
-
Novelty & Inventive Step: The claims likely emphasize structural features or methods not disclosed in prior art, such as unique substitutions, synthesis pathways, or specific therapeutic indications.
-
Scope & Limitations: The scope is likely moderate, designed to withstand prior-art challenges while preventing trivial modifications by competitors.
Patent Landscape Context
Prior Art and Novelty

Patent Filings & Priority Data
The filing date (may be the priority date if a PCT application) is crucial for assessing patent term and infringement timelines. The patent's expiration, typically 20 years from filing, influences market exclusivity.
Legal & Commercial Implications
-
Infringement Risks: Competitors with structurally similar compounds or methods should evaluate the scope of these claims.
-
Freedom to Operate: A comprehensive freedom-to-operate analysis involves examining overlapping patents across jurisdictions, particularly in key markets like Japan, US, and EU.
-
Licensing & Monetization: The patent's scope impacts licensing potential, especially if it covers a therapeutically valuable or novel compound.
-
Patent Challenges: Prior art or obviousness arguments could threaten validity, especially if similar compounds or methods exist.
Technological & Market Significance
The patent's contribution could be significant if it introduces:
-
A therapeutic breakthrough for a prevalent disease (e.g., cancer, neurological disorder).
-
A formulation reducing side effects or enhancing patient compliance.
-
A synthesis pathway that reduces manufacturing costs.
Market impact hinges on the patent's enforceability, patent family strength, and therapeutic importance. If aligned with a blockbuster drug candidate, the patent provides valuable exclusivity.
