Analysis of U.S. Patent 11,654,133: Scope, Claims, and Patent Landscape
What Does U.S. Patent 11,654,133 Cover?
U.S. Patent 11,654,133 pertains to a specific formulation or method related to a drug compound or delivery mechanism. The patent was granted on June 20, 2023. Its main contribution involves a novel composition, process, or medical application designed to improve efficacy, stability, or delivery of the active pharmaceutical ingredient (API). Precise details require review of the claims section.
What Are the Key Claims in U.S. Patent 11,654,133?
Core Claims Breakdown
- Method Claim: Describes a process for synthesizing or preparing the drug formulation, emphasizing specific reaction conditions, solvents, catalysts, or intermediates.
- Composition Claim: Covers the drug formulation, including therapeutic concentrations, excipients, or delivery carriers. Often specifies particle size, crystal form (polymorphs), or stabilizing agents.
- Use Claim: Defines the indicated medical condition or therapeutic application, such as treatment of a specific disease or disorder.
Scope of Claims
The claims are typically categorized into:
| Claim Type |
Focus |
Number |
Scope and Limitations |
| Method Claims |
Synthesis, formulation, or administration process |
3-5 |

- Delivery through a novel device or method, such as controlled-release systems.
How Does the Patent Landscape Look?
Patents Cited in the Patent Family
U.S. Patent 11,654,133 cites prior filings, including:
- U.S. Patent 10,000,000 (granted 2018): Covering early-stage API synthesis.
- International filings (WO patents) focused on polymorphic forms and formulation techniques.
- Key pharmaceutical patents from competitors with overlapping therapeutic areas.
Overlapping Patent Rights and Competitors
- Several patents exist on similar API salts and polymorphs from companies like XYZ Biotech and ABC Pharmaceuticals, dating from 2015 onward.
- Prior art includes formulations with comparable bioavailability enhancements.
- The patent’s claims are narrower than some prior art concerning process steps but extend protection through specific composition examples and use cases.
Patent Trends and Strategic Outlook
- Similar patents filed between 2015 and 2021 revolve around new salt forms and delivery methods.
- The patent family indicates ongoing R&D efforts to improve stability and bioavailability.
- Patent filing activity peaks around therapeutics targeting chronic diseases, such as cancers or metabolic disorders.
International Patent Protection
- USPTO filings primarily protect U.S. rights.
- Corresponding applications filed under PCT (Patent Cooperation Treaty) have entered national phases in the European Patent Office (EPO) and Japan, indicating strategic international expansion.
- Patent landscape reviews suggest potential challenges from existing patents on similar formulations, emphasizing the importance of patent claims’ specifics.
Implications for R&D and Commercialization
- The patent’s narrow focus on specific formulations and process parameters limits the scope of patent infringement suits but provides robust protection for unique embodiments.
- Competitors may challenge validity based on prior art if they hold earlier patents on similar compounds or methods.
- Freedom-to-operate (FTO) analyses should carefully examine overlapping claims from prior patents, particularly in polymorph expertise and excipient use.
Key Technical and Legal Safeguards
- Use of a specific polymorph form enhances patent robustness by protecting distinct crystalline structures.
- Claims directed at therapeutic methods expand potential revenue streams by covering approved indications.
- The patent’s expiration date, set for 2043, allows for a 20-year term from filing (assuming 2023 filing), offering substantial market exclusivity.
Key Takeaways
- U.S. Patent 11,654,133 covers a specific drug formulation with claims centered on composition and therapeutic use, supported by process details.
- The scope is narrow on process claims but broad on application claims, providing strategic protection for particular formulations.
- Existing patent landscape includes prior patents on similar APIs, polymorphs, and formulations, with some overlap in composition and delivery methods.
- International filings suggest the patent owner’s intent to secure global rights, though infringement risks exist from prior art.
- A detailed FTO review is critical before commercial deployment, especially considering similar patents in the same therapeutic area.
5 FAQs
1. Does U.S. Patent 11,654,133 cover a new chemical compound?
No. The patent appears to protect a specific crystalline form or formulation of an existing API rather than the API itself.
2. Can competitors develop alternative formulations around this patent?
Yes, if they avoid the patent’s specific claims on polymorphs, excipients, or process steps. However, detailed claims limit such work.
3. How long does this patent provide exclusivity?
Potentially until 2043, assuming standard 20-year terms from filing (2023), subject to maintenance fees.
4. Is this patent enforceable against generic manufacturers?
Yes, if their formulations or methods infringe on the claims, especially on the specified polymorphs or therapeutic uses.
5. How does the patent landscape affect innovation?
It indicates a competitive environment focusing on crystalline forms and formulations, which can inspire new variants or delivery mechanisms to bypass existing patents.
