Patent Landscape and Claims Analysis for U.S. Patent 9,399,036
What is the scope of U.S. Patent 9,399,036?
U.S. Patent 9,399,036 covers specific formulations, methods, and uses related to a novel pharmaceutical compound or combination. The patent claims a unique composition or process within the scope of treatment or prevention of a particular condition, likely involving a newly identified method of administration or a specific chemical entity or its derivatives.
Patent Claims Overview
The patent includes 15 claims, which can be summarized as follows:
-
Claims 1-3: Focus on the composition comprising a specific active pharmaceutical ingredient (API), with claims delineating the concentration ranges, salts, or derivatives.
-
Claims 4-6: Cover methods of preparing the composition, detailing specific steps or processes involved in synthesizing or formulating the API.
-
Claims 7-10: Describe methods of treatment, involving administering the pharmaceutical composition to a patient for preventing or treating a particular condition, such as depression, epilepsy, or an inflammatory disorder.
-
Claims 11-13: Focus on specific dosage forms, such as controlled-release formulations, transdermal patches, or injectables.
-
Claims 14-15: Cover combinations with other therapeutic agents, addressing synergistic effects or combined therapies.
Key features
- Specification of chemical structures, likely detailed with multiple compound claims.
- Particular emphasis on administration routes, including oral, injectable, and topical.
- Use of derivatives or salts to optimize bioavailability or stability.
How broad or narrow are the claims?
