What Is the Scope of U.S. Patent 11,318,130?
1. Patent Classification and Technical Field
Patent ’130 falls primarily within the taxonomy of pharmaceuticals related to small molecule therapeutics, with subclasses in oncology, neurological disorders, or infectious diseases, depending on the marketed indication. The classification likely derives from the Cooperative Patent Classification (CPC) codes, such as:
| CPC Code |
Description |
Relevance |
| A61K |
Preparations for medical or dental purposes |
Core class for drugs |
| C07D |
Heterocyclic compounds |
Likely class for the chemical skeletons involved |
| A61P |
Particular therapeutic activity |
Depending on claimed indications |
2. Core Patent Elements and Claim Constructs
a. Chemical Structure Claims
- The patent covers specific compounds characterized by a unique chemical core, e.g., a heterocyclic scaffold with particular substituents.
- Example claim format: “A compound, comprising a heterocyclic ring system attached to various substituents, wherein the substituents are selected from a specified group.”
b. Method of Production
- Claims extend to synthetic pathways, including novel intermediates, reaction conditions, and purification steps.
- Synthetically advantageous methods may broaden enforceability and patent value.
c. Therapeutic Use Claims
- These are method-of-use claims tailored to treat indications such as cancer, Alzheimer’s, or viral infections.
- Typically structured as "Use of compound X in the manufacture of a medicament for treating disease Y."
3. Claim Scope Analysis
| Type of Claim |
Breadth |
Limitations |
Implications |
| Composition Claims |
Moderate to broad |
Specific chemical structures |
Protects particular compounds but may allow exclusion of similar analogs |
| Use Claims |
Narrower |
Disease-specific, method-of-use claims |
Enforceability depends on jurisdiction and product application |
| Process Claims |
Moderate |
Specific synthetic steps |
Can prevent competition via process patent; potentially circumvents composition patent |
- The claims aim to secure both compound exclusivity and therapeutic methods, which can create a comprehensive patent barrier.
