Detailed Analysis of the Scope, Claims, and Patent Landscape for U.S. Patent 11,696,902
Introduction
U.S. Patent No. 11,696,902, granted on July 4, 2023, represents a significant patent in the pharmaceutical sector, elaborating on innovative drug compounds or formulations. This patent’s scope, defined by its claims, plays a pivotal role in shaping the patent landscape, licensing opportunities, and potential market exclusivity. This analysis dissects the patent’s claims, explores its scope, and contextualizes it within the broader patent environment.
Overview of Patent 11,696,902
The patent title and abstract suggest a focus on a novel chemical entity, formulation, or method of use related to a specific class of drugs—potentially targeting a therapeutic area such as oncology, neurology, or infectious diseases. While precise chemical or method details require a detailed review of the patent document, the core claims restrict proprietary rights over particular compounds, methods, or formulations.
Primary objective:
To establish a comprehensive understanding of the patent’s legal boundaries and how it interfaces with existing patent rights and future innovations.
Scope of the Patent
Claims Structure
The scope of U.S. patent rights is primarily determined by its claims, which in this case appear to be a combination of independent and dependent claims. The independent claims set the broadest coverage, while dependent claims narrow scope by introducing specific embodiments or features.
Independent Claims
The independent claims in Patent 11,696,902 likely describe a novel chemical compound, a composition, or a method of use with specific structural or functional characteristics. For instance, they may cover:
- A chemical entity with a unique molecular structure, potentially featuring specific functional groups or stereochemistry.
- A pharmaceutical formulation comprising the compound and excipients in specified proportions or delivery systems.
- A therapeutic method involving administering the compound to treat a particular condition.
The claims are constructed to balance broadness with novelty and non-obviousness, aiming to prevent competitors from making minor modifications to circumvent the patent.
Dependent Claims
Dependent claims specify embodiments or variants of the independent claim, such as:
- Specific substitutions or functional groups on the core molecule.
- Alternative formulations or delivery methods.
- Usage protocols, dosages, or treatment regimens.
These enhance the patent’s scope by covering different embodiments, thereby reducing the risk of design-arounds.
Key Elements and Limitations of the Claims
Chemical Structure Patents
If the patent covers a chemical entity, the claims detail the molecular formula, specific substituents, and stereochemistry. Limitations include the scope of chemical modifications that do not infringe—highlighting the importance of claim breadth.
Method of Use Claims
Method claims may encompass specific methods of administering the drug, determining patient eligibility, or combination therapies. These claims often complement product claims, providing additional layers of exclusivity.
Formulation and Delivery Claims
Claims may specify particular formulations (e.g., sustained-release, liposomal) or delivery systems (e.g., nanoparticle carriers).
Limitations and Exclusions
Claims prudently exclude prior art or known compounds, ensuring patentability. They may also define specific therapeutic indications, thereby limiting scope to certain diseases or conditions.
Patent Landscape Context
Related Patents and Prior Art
Patent 11,696,902 exists within a broader landscape of patents targeting similar drug classes or therapeutic methods. Analysis of the landscape reveals:
- Foreground Patent Family: Likely part of a patent family with international counterparts, providing territorial protection beyond the U.S.
- Prior Art Citations: The patent cites prior patents and publications disclosing related compounds or methods, which serve as background and novelty benchmarks.
- Design-Arounds and Innovation: Competitors may attempt to design-around the patent by modifying molecular structures, substituents, or delivery systems not covered by the claims.
Competitor Patents
Competitors' patents could challenge the scope of 11,696,902 if their claims overlap. Conversely, patent holders or licensees can leverage extensive claim chains to defend or enforce exclusivity.
Legal and Patentability Considerations
- Novelty: The claim’s chemical structures or methods must differ significantly from prior art.
- Non-Obviousness: Demonstrating inventive step, especially for chemical modifications, is essential.
- Drafting Strategy: The claims’ phrasing must balance broad protection with defensibility amidst potential invalidation challenges.
Implications for the Pharmaceutical Market
The scope and claims delineation influence:
- Market Exclusivity: Broad claims covering key compounds or methods reinforce a dominant market position.
- Licensing Strategies: Strategic claim scope enables licensing negotiations with generic manufacturers or biosimilar developers.
- Research and Development: Clear claim boundaries guide ongoing innovation, avoiding infringement and fostering complementary developments.
Conclusion
U.S. Patent 11,696,902 enshrines a precise yet strategic scope within its claims, aiming to secure patent rights over a novel compound, formulation, or therapeutic method. Its breadth and clarity are essential to robust enforcement and market valuation, especially amid evolving patent challenges and competing innovations. A nuanced understanding of its claims facilitates informed licensing decisions, patent litigation strategies, and R&D investments.

FAQs
1. What is the primary innovation claimed in U.S. Patent 11,696,902?
The core innovation likely involves a novel chemical compound, formulation, or method of therapeutic use with unique structural or functional features, although exact details require review of the specific claims.
2. How does claim breadth affect patent enforceability?
Broader claims afford wider protection but are more susceptible to invalidation due to prior art. Narrower claims reduce infringement scope but enhance legal robustness.
3. Can competitors develop similar drugs and avoid infringement?
Yes, by modifying the molecular structure, delivery method, or therapeutic application in ways not covered by the claims, competitors can design-around the patent.
4. How does this patent compare to international patents?
It’s likely part of a broader patent family filing internationally, offering similar protection in jurisdictions like Europe, Japan, and China, depending on global patent prosecution strategies.
5. What are the key considerations for licensing this patent?
Potential licensees assess the scope of claims, the patent’s enforceability, remaining patent life, and market demand for the covered drug or method.
