What Is the Scope of U.S. Patent 10,592,168?
1. Patent Classification and Field
-
International Patent Classification (IPC):
The patent generally falls within classes related to pharmaceuticals, such as A61K (Preparations for medical, dental, or toiletry purposes), C07D (Heterocyclic compounds), or A61P (Therapeutic activity of chemical compounds or compositions).
-
CPC Classification:
Likely includes A61K subclasses with specific emphasis on a subclass related to the compound class or delivery method (e.g., A61K 31/00 for heterocyclic compounds or A61K 47/00 for combinations).
2. Patent Family and Filing Priority
- The patent’s priority date and family assets influence scope breadth.
- Filed apps from 2017–2018 with continuations or divisional applications could extend scope or refine claims.
- Its family members are likely filed internationally, particularly in jurisdictions such as Europe (via EP applications), China, and Japan, impacting global patent rights.
3. Core Innovation
- The patent claims protection over a novel compound, composition, or method of treatment.
- Likely centers on a new molecular entity—a specific chemical structure—or a method of administering such compounds.
Claims Analysis
1. Scope of Claims
| Claim Type |
Description |
Maximal Breadth |
Implication |
| Independent Claims |
Broad claims covering the core invention (e.g., a novel compound or method) |
Typically broad, e.g., a class of molecules or techniques |
Sets the outer boundary of patent rights |
| Dependent Claims |
Narrower claims refining the independent claim, adding limitations |
More specific, e.g., specific substituents, methods |
Defines particular embodiments or preferred versions |
2. Typical Features of the Claims
-
Chemical Structure Claims:
Depictions of the molecular framework, including specific substituents, stereochemistry, and core heteroatoms.
-
Method Claims:
Protocols for administering the compound, dosage regimes, or treatment indications.
-
Preparation/Process Claims:
Refinements of synthesis or formulation methods.
3. Claim Language and Patent Scope
-
Words such as “comprising,” “consisting of,” or “wherein” influence scope:
- “Comprising” is open, allowing additional elements.
- “Consisting of” is closed, limiting scope strictly to described elements.
-
The use of Markush groups allows claiming classes of compounds, broadening scope but risking obviousness challenges.
