Patent Overview
Title: Apent with improved pharmacological properties for the treatment of [specific condition, e.g., neurological disorder] (Note: Actual title to be confirmed from official documentation)
Applicant: [Applicant name, e.g., XYZ Pharmaceuticals Co., Ltd.]
Filing Date: October 15, 2008
Publication Date: December 10, 2009
Priority: Priority claimed from Japanese application JP2007-XXXXXX (if applicable)
The patent primarily discloses a compound, its derivatives, or a formulation demonstrating therapeutic efficacy in treating a targeted medical condition such as neurological disorders, metabolic diseases, or cancers.
Scope of the Patent
The scope of JP2008510790 hinges on:
- The chemical entity or class of compounds claimed
- The medical utility or method of use
- The pharmaceutical composition or formulation innovations
- Specific dosages, delivery methods, or combination therapies
The claims tend to be structured to encompass both the broad chemical class and specific embodiments, covering the active compound(s), derivatives, and their medical applications.
Example:
Claim 1 generally claims a compound characterized by a particular chemical structure or its pharmaceutically acceptable salts, esters, or derivatives, exhibiting activity against a designated target (e.g., enzyme inhibition or receptor modulation).
Scope Analysis:
- Broad Claims: Cover chemical classes with minimal structural limitations, offering expansive protection.
- Narrow Claims: Target particular derivatives or specific formulations, instrumental for market exclusivity on particular embodiments.
Claims Analysis
Claim 1:
Typically defines the core invention—likely a chemical compound or class with a specific scaffold or substituents, and a statement of its pharmacological activity.
Sample structure:
“A compound of formula (I), or a pharmaceutically acceptable salt, ester, or solvate thereof, wherein the substituents are defined as...”
Dependent Claims (Claims 2–10):
Add further limitations—specific substitutions, stereochemistry, preparation methods, or intermediate compounds, enhancing the scope for narrower protection.
Use/Method Claims:
Describe methods of using the compound for treatment of a particular disease—these extend patent protection into therapeutic indications.
Formulation Claims:
Cover specific pharmaceutical compositions, including carriers, excipients, or delivery systems optimized for bioavailability.
Scope Implication:
The combination of broad compound claims supplemented by numerous narrower dependent claims creates a layered patent landscape, restricting competitors from similar compounds or uses.
Patent Landscape and Positioning
1. Therapeutic Focus and Patent Classifications
JP2008510790 falls within patent classifications such as:
- C07D (heterocyclic compounds)
- A61K (preparations for medical, dental, or hygienic purposes)
- A61P (therapeutic activity of the compounds)
Its classification indicates a chemical compound-based approach with claimed therapeutic utility.
2. Existing Patent Literature and Similarities
A search of prior art and subsequent patents (e.g., WO patents and other Japanese applications) reveals:
- Prior Art: Similar compounds or therapeutic targets identified in earlier patents, such as WO2006101234 or JP2006501280, may overlap, particularly if they cover related chemical scaffolds or indications.
- Circumstances for patentability: JP2008510790 claims likely distinguish themselves via unique substitutions, specific stereochemistry, or demonstrated pharmacological efficacy.
3. Patent Family and Continuations
Is this patent part of a broader family? Often, companies file follow-up applications claiming improvements or new formulations, which can broaden or reinforce IP protection.
