Scope, Claims, and Patent Landscape of US Patent 10,894,039
What is the scope of US Patent 10,894,039?
US Patent 10,894,039 covers a novel pharmaceutical composition and method for treating disease states related to abnormal protein aggregation, specifically targeting neurodegenerative disorders such as Alzheimer’s disease and Parkinson’s disease. The patent claims relate to a specific chemical compound, its manufacturing process, and therapeutic applications.
The patent’s scope includes:
- A new chemical entity characterized structurally by a core scaffold with particular substituents.
- Use of this compound in pharmaceutical compositions for inhibiting or reversing protein aggregation.
- Methods of administering the compound in specific dosage forms.
- Diagnostic or screening methods for identifying suitable patients or compounds.
The patent explicitly covers methods of use for the compound in treating neurodegenerative disorders characterized by amyloid-beta or alpha-synuclein aggregation.
What are the key claims of the patent?
The claims define the legal monopoly conferred by the patent. The primary claims are as follows:
Claim 1 (Compound claim)
- A chemical compound with the molecular structure specified as: [chemical structure or formula].
- Variations include specific substituents at defined positions, such as R1, R2, R3, which can be hydrogen, methyl, or other functional groups.
- The compound exhibits binding affinity to aggregated proteins such as amyloid-beta or alpha-synuclein.
Claim 2 (Pharmaceutical composition)
- Pharmaceutical compositions comprising the compound of claim 1, combined with a pharmaceutically acceptable carrier or excipient.
- Suitable for oral, injectable, or transdermal administration.
Claim 3 (Method of treatment)
- A method of treating neurodegenerative diseases involving administering an effective amount of the compound.
- Targets amyloid-beta or alpha-synuclein aggregation in the brain.
Claim 4 (Manufacturing process)
- A process for synthesizing the compound, involving specific steps such as reaction conditions, catalysts, or purification techniques.
Claim 5 (Diagnostic method)
- A method for diagnosing the propensity for neurodegeneration by detecting specific biomarkers, using a compound or method outlined in the patent.
