2. Scope of the Patent
2.1 General Scope and Purpose
The scope of this patent encompasses chemical structures, compositions, or methods that relate to a particular therapeutic target, disease treatment, or drug delivery mechanism. It aims to protect specific innovations around a drug candidate or formulation, potentially including:
- Chemical compounds with unique molecular modifications
- Pharmaceutical compositions involving these compounds
- Administration methods or formulations for enhanced efficacy or stability
- Therapeutic indications, such as certain cancers, metabolic disorders, or infectious diseases
2.2 Patent Classifications and Their Significance
The patent overlaps several IPC (International Patent Classification) and CPC (Cooperative Patent Classification) codes, which are critical in defining the technological scope:
- A61K: Preparations for medical, dental, or cosmetic purposes — the core classification for pharmaceuticals
- C07D: Heterocyclic compounds — suggests compounds with heterocyclic structures, common in many drugs
- A61P: Specific therapeutic activity — indicates targeted treatment, such as anti-cancer or anti-inflammatory actions
The combination of these classes underscores the patent’s focus on chemical entities with therapeutic utility, especially heterocyclic compounds.
3. Claims Analysis
3.1 Types of Claims
The claims in JP2012513396 typically include:
- Independent Claims: Broad coverage of the core chemical structure or therapeutic method. These define the boundary of the patent's protection.
- Dependent Claims: Narrower claims that specify particular embodiments, such as specific derivatives, dosage forms, or methods of use.
3.2 Typical Scope of the Claims
While the explicit claims are not provided here, standard pharmacological patents of this nature generally include:
- Chemical structure claims: Covering a family of compounds with a defined core skeleton, often including variables representing substituents, different heteroatoms, or functional groups.
- Method claims: Covering a specific method of manufacturing or administering the compound or composition.
- Therapeutic claims: Covering the use of the compounds in specific diseases or conditions.
Sample claim structure:
"A compound of formula I, wherein the substituents are as defined herein, for use in the treatment of [disease]".
This structure aims to provide broad coverage over all compounds fitting a generalized structure, provided they meet specific substituent parameters.
3.3 Novelty and Inventive Step
The claims likely emphasize the novelty of specific substituents, configurations, or therapeutic methods that distinguish this invention from prior art. For instance, modifications to heterocyclic rings that improve bioavailability or reduce side effects are common claim strategies.
4. Patent Landscape
4.1 Major Competitors and Similar Patents
The patent landscape surrounding JP2012513396 involves multiple layers:
- Prior Art: Numerous patents and patent applications related to heterocyclic drugs, kinase inhibitors, or similar therapeutic agents are relevant. For example, patents in the same class may include filings from global pharmaceutical giants such as Pfizer, Novartis, or Takeda.
- Patent Families: The assignee may have corresponding filings elsewhere (e.g., US, EP, CN), forming a patent family that strengthens global protection.
