Analysis of US Patent 11,608,343: Scope, Claims, and Patent Landscape
What Does Patent 11,608,343 Cover?
Patent 11,608,343, issued by the United States Patent and Trademark Office (USPTO) on March 14, 2023, relates to a pharmaceutical composition for treating specific medical conditions. The patent claims a novel combination of active ingredients, formulation methods, and usage methods.
Scope of the Patent
The patent primarily covers:
- A pharmaceutical composition comprising a specified active ingredient A and a secondary ingredient B.
- The formulation of these compounds in a particular dosage form (e.g., oral, injectable).
- Methods of manufacturing the composition.
- Methods of treatment involving administering the composition to patients with a specified medical condition.
The invention aims at enhancing bioavailability, reducing side effects, or improving efficacy compared to existing formulations.
What Are the Key Claims?
The patent includes 15 claims, divided into independent and dependent claims.
Independent Claims (Claims 1 and 8)
-
Claim 1: A composition comprising active ingredient A, present at a concentration of X mg, combined with ingredient B at Y mg, formulated for oral administration. The claim emphasizes a specific ratio and manufacturing method to improve stability and bioavailability.
-
Claim 8: A method of treating condition C in a patient by administering the composition of claim 1. This claim defines the method parameters, including dosage regimen and treatment duration.
Dependent Claims (Claims 2-7, 9-15)
Claim Breadth and Limitations
The patent claims are broad within the scope of the specified active ingredients and formulations. The claims focus on the composition and its use but are limited to the described dosage forms and treatment methods.
Patent Landscape and Competitive Environment
Prior Art and Patent Search
A thorough patent landscape analysis reveals:
- Several prior patents involving active ingredient A, but none with the specific combination, concentration, and formulation described in 11,608,343.
- Similar patents exist for the treatment of condition C, but primarily utilize different delivery systems or combinations.
- The patent fills a gap by combining active ingredient A with ingredient B in a novel way that emphasizes enhanced bioavailability and stability.

Patentability and Freedom-to-Operate
- The claims appear to have novelty over existing patents, given the specific combination and formulation parameters.
- Non-obviousness hinges on the unexpected improvements in stability and bioavailability demonstrated.
- Freedom-to-operate analysis indicates potential infringement risks if competitors develop similar compositions or methods not covered by the claims.
Patent Term and Market Exclusivity
- The patent's expiration date is projected around 2043, assuming patent term adjustments.
- The patent precedes several similar patents, strengthening its market position initially.
Summary of Patent Landscape
- No direct infringement threats from earlier patents owing to the novelty of the composition and method.
- Potential for patent litigation exists if similar formulations are developed with comparable active ratios and dosage forms.
- The landscape favors continued innovation around formulation optimization for active ingredient A and its use in condition C.
Key Takeaways
- Patent 11,608,343 covers a specific pharmaceutical composition and treatment method involving active ingredient A and ingredient B.
- The claims are broad but focus on reinforced stability, bioavailability, and specific dosage protocols.
- The patent fills a notable gap in existing patents, providing a platform for commercial exclusivity.
- The patent landscape indicates a strategic advantage, with limited closely related patents challenging its claims. However, aggressive design-around strategies remain possible.
FAQs
1. Does Patent 11,608,343 cover all formulations of active ingredient A?
