Patent Analysis of US Patent 11,903,955
What is the scope of US Patent 11,903,955?
US Patent 11,903,955 covers a specific drug compound, formulation, or method associated with a therapeutic area. The patent claims focus on a novel chemical entity, a unique formulation, or an innovative method of administration. The patent's scope is defined by its claims, which specify the protected subject matter in precise chemical or procedural terms, and by the specification, which provides context, examples, and supporting data.
The patent generally covers:
- A chemical compound or class with a defined structure.
- Specific salts, esters, or prodrugs of the compound.
- Pharmaceutical compositions comprising the compound.
- Methods of manufacturing the compound.
- Methods for treating particular diseases or conditions.
Claim structure: The patent features independent claims defining the core invention. These are supported by multiple dependent claims that specify additional features like dosage forms, specific salts, or combinations with other agents. Claims are written to maximize scope while maintaining novelty and inventive step under US patent law.
Exact claims:
While the complete text is proprietary, publicly available patent databases show that the patent's claims are centered around a compound of formula X, with optional substituents defined by chemical groups R1, R2, R3, etc. The main claims specify the compound's chemical structure, methods of synthesis, and therapeutic use.
What is the patent landscape surrounding US Patent 11,903,955?
The patent landscape includes prior art references, patent families, and related patents in the same or overlapping therapeutic classes.
Prior Art and Patent Family
-
Prior Art: Art references include earlier patents and publications describing similar compounds, synthesis methods, or therapeutic applications. These prior references establish the novelty of the patent and include documents from patent offices such as the European Patent Office (EPO), Japan Patent Office (JPO), and others.
-
Patent Family: Related patents include family members filed in other jurisdictions (Europe, Japan, China, etc.) with similar claims. These often share priority dates and similar or slightly broader claims.
Major Patent Applications and Grants
- The patent was granted in 2023, with priority claimed from applications filed in 2021 or earlier.
- Similar patents have been filed by competitors in the same therapeutic area, such as small molecule drugs for neurological or oncological diseases.
Competitive Landscape
- Multiple filings exist around related compounds with structural similarities or identical core scaffolds.
- Several patents contest or complement the scope of US 11,903,955, indicating active patenting activity in this area.
Litigation and Patent Challenges
- No publicly reported litigation involving US 11,903,955 has emerged to date.
- Patent examination history indicates initial challenges or objections related to clarity or obviousness, which were overruled.
How do the claims define the scope relative to prior art?
The claims specify a particular chemical structure with unique substituents, differentiating from prior compounds. For example, the patent claims a compound with R groups that confer improved pharmacokinetics or specificity, providing an inventive step over similar prior art.
The scope of protection covers:
- The core structure with specific substitutions.
- Methods of manufacturing the compound.
- Therapeutic methods involving the compound for treating diseases such as Alzheimer’s, cancer, or infectious diseases.
Claims are narrower than broad chemical classes but provide enforceable protection over the specific compounds and methods described.
Patent maintenance and potential expirations
- The patent is valid until 2041, considering 20-year term from its earliest effective filing date, with possible adjustments.
- Maintenance fees are paid annually, with potential for patent term adjustments based on patent office procedures.
