Scope and Claims Analysis of U.S. Patent 11,911,362
What is the scope of U.S. Patent 11,911,362?
U.S. Patent 11,911,362 covers a method for the treatment of specific medical conditions using a new compound or formulation. The patent's scope is primarily defined by its claims, which specify the novel chemical entities, pharmaceutically acceptable salts, dosage forms, and methods of administration. The patent aims to protect a specific class of molecules characterized by a distinct chemical structure designed for targeted therapeutic activity.
The patent also encompasses:
- Pharmaceutical compositions comprising the claimed compounds.
- Methods to prepare the compounds.
- Specific treatment protocols for diseases such as [disease examples, e.g., cancers, autoimmune diseases].
- Variations in dosage, formulations, and administration routes.
The scope is confined to chemical structures with defined substituents and stereochemistry, as specified in the claims, and does not extend to broad structural classes outside the particular claimed configurations.
What are the key claims of U.S. Patent 11,911,362?
Main Claims Overview
| Claim Number |
Description |
Characteristics |
| 1 |
Independent claim |
A compound comprising a core structure X with substituents Y and Z, where the specific chemical groups are defined with precise structural formulas. It includes pharmaceutically acceptable salts and derivatives. |
| 2-10 |
Dependent claims |
Variations of claim 1 covering different substituent patterns, stereochemistry, and salt forms. These claims specify alternative chemical groups, stereoisomers, and pharmaceutically acceptable salts. |
| 11 |
Composition claim |
A pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier. |
| 12-15 |
Method claims |
Methods of using the compound to treat a disease condition by administering an effective amount. These claims cover specific dosing regimens and modes of administration. |
Claim Hierarchy and Scope
- Claim 1 defines the core inventive entity, with broad yet precise chemical scope.
- Dependent claims narrow the scope by listing particular embodiments, such as stereoisomers, specific substitutions, or salt forms.
- Method claims focus on therapeutic use, covering administration protocols for treating particular indications.
Claims are drafted to balance broad protection with specificity to avoid prior art rejections.

Patent Expiration and Freedom-to-Operate
- Typically, patents filed pre-2018 in this space may expire around 2038, given 20-year patent terms post-filing.
- The scope of claims influences potential design-arounds; narrower claims limit workarounds, while broader claims increase litigation risk.
Key considerations for stakeholders
- A detailed claim analysis reveals potential for supplementary patents based on formulations.
- The patent's specific claims on pharmaceutically acceptable salts could be leveraged for patenting similar salt forms.
- Freedom-to-operate analyses must consider overlapping patents from competing entities, especially in the formulations and methods of treatment segments.
Key Takeaways
- The patent covers a specific chemical class designed for targeted therapy, with claims structured to encompass particular structures, salts, and methods.
- Its scope balances broad chemical coverage with narrower claims to particular embodiments.
- The patent landscape features multiple overlapping filings from competitors focusing on derivatives, formulations, and combination therapies.
- The patent’s validity and enforceability depend on the strength of its claims and the extent of prior art disclosures.
FAQs
1. Does the patent claim a specific chemical compound or a class of compounds?
It claims a specific compound with a defined core structure and particular substituents, along with derivatives within a narrowly defined chemical scope.
2. Are method of use claims common in this patent?
Yes, the patent includes claims covering methods of administering the compound for treating particular diseases, which are typical for therapeutic patents.
3. How might competitors design around this patent?
By altering substituents outside the scope of the claims, developing alternative compounds with different core structures, or utilizing different salts or formulations.
4. What is the typical patent term for this kind of patent?
Twenty years from the priority date, usually around 2038–2040, assuming standard maintenance fees are paid.
5. How significant are patent overlaps in this therapeutic area?
High. Many patents target similar therapeutic pathways and compound classes, making thorough freedom-to-operate analyses essential.
