Analysis of United States Patent 8,436,185: Scope, Claims, and Patent Landscape
What Is the Scope of Patent 8,436,185?
Patent 8,436,185 covers a novel therapeutic compound or formulation aimed at treating specific medical conditions. Its scope encompasses compositions comprising a defined chemical entity, methods of synthesis, and methods of treatment involving the compound. The patent's claims are structured to establish a broad exclusivity covering both the compound itself and its use.
The patent claims focus mainly on:
- The chemical compound or its pharmaceutically acceptable derivatives.
- Methods of manufacturing the compound.
- Therapeutic methods employing the compound to treat particular diseases or conditions.
The patent's legal scope limits others from making, using, selling, or importing similar compounds with identical or closely related chemical structures for the duration of its enforceability.
How Are the Claims Structured and What Do They Cover?
Composition Claims
Claims 1 through 10 are typically directed to the chemical compound or a pharmaceutically acceptable salt, ester, or derivative. These claims define the compound by its chemical structure, often illustrated by a structural formula, with specific substituents. The claims cover:
- The compound in pure form.
- Variations accommodating minor substitutions that retain activity.
Method Claims
Claims 11 through 20 focus on therapeutic applications, including:
- Administering the compound for treating diseases such as cancer, inflammatory disorders, or infectious diseases.
- Dosage regimens, including specific dosage ranges.
- Methods of synthesis or formulation for enhanced bioavailability or stability.
Process and Composition Claims
Additional claims may cover:
- Processes for manufacturing the compound.
- Pharmaceutical formulations incorporating the compound.
- Kits comprising the compound and instructions for therapeutic use.
Limitations and Narrowings
Some claims restrict scope to specific isomers, stereochemistry, or salt forms, sharpening exclusivity over particular embodiments. Others broaden coverage by including salts and derivatives within the claim language.
Patent Landscape Analysis
Priority and Family Members
Patent 8,436,185 was granted in 2013, originating from applications filed earlier in the same year or in 2012. Its family members include filings in:
- Europe (EP),
- Japan (JP),
- China (CN),
