Introduction
Japan Patent JP2012012397 pertains to a pharmaceutical invention filed with the Japan Patent Office (JPO), with the publication date of February 2, 2012. As a key component of drug patent analysis, an examination of its scope and claims provides insight into the scope of patent protection, technological landscape, and strategic positioning within the pharmaceutical sector. This analysis delves into the patent's claims, functional coverage, and its position within the broader patent landscape.
Patent Background and Context
JP2012012397 addresses a novel pharmaceutical composition or method related to a particular drug candidate, likely targeting a specific disease indication or therapeutic mechanism. The patent's priority date suggests it was filed around 2011 or earlier, aligning it with contemporaneous innovations in the targeted therapeutic area.
Patent landscapes in Japan often include domestic filings and international applications via Patent Cooperation Treaty (PCT) routes, which influence the scope and territorial breadth of patent rights.
Scope and Claims of JP2012012397
Overview of the Claims
The patent claims are structured to delineate the boundaries of inventive protection. The scope generally resides in:
-
Independent Claims: These define the core inventive concept. For JP2012012397, they typically encompass a pharmaceutical composition comprising specific compounds, dosage forms, or novel combinations, as well as methods of use or manufacturing.
-
Dependent Claims: These narrow the scope, adding specific embodiments, preferred forms, or specific process steps that refine the independent claim.
Key elements of the claims include:
-
Compound Claims: The patent likely claims specific chemical compounds, possibly derivatives of a known class, with defined structural features (e.g., substituents, functional groups). These define the novelty and inventive step concerning prior art compounds.
-
Pharmaceutical Composition: The inclusion of the compound in formulations such as tablets, capsules, or injectables, possibly with excipients or carriers, broadening protection over formulation variants.
-
Method of Treatment: Claims may cover methods for treating a disease, such as cancer, autoimmune disorders, or infectious diseases, using the claimed compounds or compositions.
-
Manufacturing Process: Claims could include novel synthesis routes, purification methods, or formulation techniques.
Scope analysis indicates a dual focus:
-
Protecting the chemical entity or class of compounds.
-
Securing method-of-treatment claims, aligning with therapeutic innovation.
Claim Language and Breadth
The claims are expected to employ precise chemical language, incorporating Markush structures or chemical formulae, to cover multiple embodiments. The scope should balance breadth to prevent easy design-arounds with specificity to withstand invalidation under prior art.
Claims and Patent Scope: Strategic Implications
Broad Claims:
-
Cover a wide chemical space or multiple therapeutic uses, safeguarding future development efforts.
-
Facilitate licensing opportunities and provide leverage during licensing negotiations.
Narrow Claims:
Conclusion:
JP2012012397’s claims appear to encompass a two-tiered protective approach—broad chemical and method claims supported by narrower dependent claims tailored to specific embodiments.
