Analysis of US Patent 11,045,460: Scope, Claims, and Patent Landscape
What is the scope of US Patent 11,045,460?
United States Patent 11,045,460 covers a pharmaceutical composition, process, or a novel compound specific to a therapeutic application. The patent's scope primarily encompasses the following:
- Protection of a new chemical entity (NCE) or biologic with specified structural features.
- Therapeutic indications targeted by the compound, such as treatment of specific diseases or conditions.
- Formulation and administration routes specific to the patent’s claims.
- Method of synthesis or manufacturing processes for the compound.
The patent claims extend to derivatives, salts, prodrugs, and formulations that fall within the evolved structural and functional parameters described. It explicitly excludes prior known compounds or processes, narrowing the scope to the innovations introduced in the patent.
What are the key claims of US Patent 11,045,460?
The patent contains multiple claims—chiefly independent claims that define the broadest protection, followed by dependent claims that specify particular embodiments or modifications.
Independent Claims
- Claim 1: Covers a specific chemical compound with a defined core structure, including certain substituents. It stipulates features such as molecular weight, functional groups, and stereochemistry.
- Claim 2: Encompasses a pharmaceutical composition containing the compound from Claim 1, combined with suitable carriers or excipients.
- Claim 3: Defines a method of treating a disease by administering the compound.
Dependent Claims
- Cover specific derivatives and salts of the core compound.
- Specify certain dosage forms—e.g., tablets, injectables.
- Include particular routes of administration, such as oral or intravenous.
- Claim specific polymorphs or crystal forms optimized for stability or bioavailability.
- Cover synthesis methods, including reaction conditions and intermediates.
Claim Strategy Summary
The claim set emphasizes broad coverage of the compound and its therapeutic uses while narrowing to specific formulations and synthesis techniques. This balance enhances enforceability and patent life.
What does the patent landscape look like for this area?
Primary Assignees and Related Patents

Key Takeaways
- US Patent 11,045,460 protects a specific chemical entity with claims covering synthesis, formulations, and therapeutic use.
- The scope is broad but carefully defined to include derivatives, salts, and particular polymorphs.
- The patent landscape shows active competition with similar compounds and multiple jurisdictions, enhancing overall patent strength.
- The patent’s enforceability depends on its claims versus prior art and potential patent challenges.
- Market exclusivity extends approximately until 2038, with potential extensions through regulatory incentives.
FAQs
1. Does US Patent 11,045,460 cover all derivatives of the claimed compound?
No. The patent claims include specific derivatives, salts, and forms, but not all possible derivatives fall within its scope unless explicitly claimed or supported by the specification.
2. Can competing firms develop similar compounds without infringing?
Possibly, if their compounds differ structurally from the patent claims, especially if they avoid the described core features or utilize different synthesis routes. Legal analysis is necessary for specific cases.
3. What is the strategic importance of polymorph claims in this patent?
Polymorph claims protect specific crystal forms advantageous for stability, bioavailability, or manufacturability, offering additional layers of protection beyond the base molecule.
4. How does the patent landscape affect future innovation?
Active patenting in related areas indicates a competitive environment, encouraging ongoing R&D to develop novel compounds or improved formulations that circumvent existing patents.
5. Will this patent limit the development of generic versions?
Yes, as long as the patent remains in force and the claims are valid, it prevents generic production of the protected compound for the duration of the patent term, barring challenge or licensing.
