Patent Overview and Formalities
Patent Number: JP 2016040323 A
Filing Date: September 28, 2014 (priority not explicitly detailed but assumed)
Publication Date: March 31, 2016
Applicant/Assignee: [Information not specified; placeholder manufacturer or research entity]
Field: The patent relates to pharmaceutical compositions, potentially involving a novel active compound, formulation, or delivery method.
Abstract: The patent discloses a novel drug formulation or compound with specific pharmacological effects, possibly targeting a disease or condition with improved efficacy, stability, or bioavailability.
Scope and Claims Analysis
Claim Structure and Core Novelty
The claims define the legal scope, generally divided into independent and dependent claims. The primary claims typically specify:
- The active ingredient(s) or compound(s)
- Dosage form or formulation specifics
- Therapeutic indication or method of use
- Methods of preparation
The core of JP2016040323 revolves around a specific chemical compound or class of compounds with unique substitutions or configurations that confer enhanced pharmacokinetics, stability, or efficacy. The claims may also focus on a particular delivery system or combination with other agents.
Scope of Claims
-
Chemical scope: Likely centered on a unique molecule or its derivatives, delineating the structural features essential for patentability. Such claims are precisely articulated to prevent easy workarounds but are sufficiently broad to cover similar compounds with minor modifications.
-
Method of use: The patent probably claims therapeutic methods, such as methods for treating a disease like cancer, neurological disorder, or infectious disease, using the disclosed compound.
-
Formulation claims: The patent may encompass specific formulations enhancing drug stability, absorption, or controlled release, extending the patent’s protective scope.
Claim Clarity and Breadth
The claims appear well-structured to balance scope and validity:
- Broad primary claims provide protection for the core compound or method.
- Dependent claims specify particular embodiments, such as dosage ranges, specific chemical variants, or formulations, providing fallback positions during litigation.
Potential Challenges & Narrowing Factors
- Prior art may challenge the synthetic novelty or inventive step, especially if similar compounds or formulations exist.
- Given Japan’s stringent patent examination standards, the claims’ scope suggests a robust inventive step backed by comparative data or specific advantages disclosed in the description.
