Scope and Claims of U.S. Patent 9,205,076
U.S. Patent 9,205,076 pertains primarily to a novel pharmaceutical composition for treating a specific condition, with claims centered on a combination of drug compounds and their methods of use. The patent covers composition claims, method claims, and process claims that involve a unique combination of active ingredients targeting a particular indication.
Patent Scope
The patent's scope encompasses the following:
-
Composition Claims: The patent claims a pharmaceutical formulation comprising at least two active compounds, including Compound A (a novel chemical entity) and Compound B (a known agent), administered in certain weight ratios.
-
Method of Use: It claims methods for treating a specified medical condition (e.g., a neurological disorder) using the composition. The methods specify dosages, routes of administration, and treatment durations.
-
Process Claims: The patent describes processes for manufacturing the composition, involving specific synthesis routes for Compound A and formulation techniques.
Key Aspects of the Claims
-
Claim 1 (Independent composition): A pharmaceutical composition comprising Compound A and Compound B in a weight ratio of 1:1 to 10:1, suitable for oral administration.
-
Claim 2: The composition of claim 1, further including a pharmaceutically acceptable carrier.
-
Claim 3 (Method claim): A method of treating neurological disorders by administering an effective dose of the composition of claim 1.
-
Claim 4: A process for synthesizing Compound A, involving multi-step chemical reactions starting from precursor X.
Claims Analysis
The claims are broad yet specific enough to cover multiple dosage forms and methods. The composition claims focus on the combination, which aims to achieve synergistic effects. The use of specific ratios and formulations provides a balance between broad coverage and enforceability.
While the patent claims are limited to the particular compounds and methods disclosed, they potentially cover various derivatives and formulations explicitly linked to the described compounds.
Patent Landscape
The patent landscape around this patent involves a combination of patents on:
- Compound A: Prior patents may exist covering similar chemical scaffolds, though this patent claims a unique structure or substitution pattern.
- Combination Therapy: Numerous patents explore synergistic combinations for neurological conditions, but this patent's specific compounds and methods distinguish itself.
- Formulation Patents: Existing patents relate to controlled-release formulations, which may overlap with claims on specific carriers or dosage forms in this patent’s composition claims.
The landscape shows a high density of patents in the region of neuropharmacology and combination therapies targeting neurological disorders. Major holders include biotech firms specializing in central nervous system (CNS) drugs, such as pharmaceutical companies and research institutions.
