Introduction
U.S. Patent 9,604,018, titled “Methods of Treating Diseases Using Novel Compounds,” was granted on March 28, 2017, and assigned to a leading pharmaceutical innovator. This patent centers on a specific class of chemical compounds claimed for their therapeutic efficacy in treating a range of diseases, particularly related to inflammation and metabolic disorders. This analysis evaluates the scope and claims set forth in the patent and examines the broader patent landscape relevant to the underlying technological field.
Scope of U.S. Patent 9,604,018
The patent’s scope primarily encompasses novel chemical entities, their pharmaceutical compositions, and methodologies for their use in treating specified diseases. These compounds are characterized by specific chemical structures, notably a core scaffold with flexible substitutions, enabling targeted therapeutic applications.
Core Structural Features
The patent emphasizes compounds of a defined general formula, often involving heterocyclic moieties attached to aromatic rings, with particular emphasis on substitutions that improve pharmacokinetics and target binding affinity. The chemical space is expansive yet sufficiently defined—allowing for a broad family of derivatives while maintaining structural specificity.
Therapeutic Indications
Claims explicitly extend to methods of treating autoimmune diseases, inflammatory conditions, metabolic syndromes, and certain cancers. The patent’s scope is thus aligned with diseases where modulation of inflammatory or metabolic pathways plays a therapeutic role.
Product Claims
Apart from compound claims, the patent also encompasses pharmaceutical compositions and methods of administration, often involving combination therapies with other drugs, further expanding the scope beyond individual molecules.
Claims Analysis
The patent contains multiple claims, divided into independent and dependent claims. These claims delineate the legal scope and limitations, with the independent claims establishing broad coverage.
Independent Claims
The independent claims typically cover:
- A compound of Formula I (or similar) with specified substituents.
- A pharmaceutical composition comprising these compounds.
- A method of treating one or more diseases through administering these compounds or compositions.
For example, Claim 1 broadly claims a compound of a specific formula with defined positions for substituents, encompassing all derivatives that fit within the structural parameters.
Dependent Claims
Dependent claims specify particular substitutions, stereochemistry, and formulations, narrowing the scope but providing fallback positions for patent protection. They often specify:
- Particular substituents (e.g., methyl, halogen, hydroxyl groups).
- Specific disease indications such as rheumatoid arthritis, psoriasis, or type 2 diabetes.
- Delivery methods such as oral, intravenous, or topical administration.
Claim Strategy & Breadth
The patent employs a trust-blown claim strategy, balancing broad claims with multiple narrower, dependent claims. This approach offers resilience against challenges and scope for various therapeutic applications. However, the breadth hinges on the inventive step associated with the core chemical scaffold and its demonstrated efficacy.
Patent Landscape Overview
The patent landscape surrounding U.S. Patent 9,604,018 reflects an active domain characterized by a dense network of overlapping patents, primarily in selective kinase inhibitors, anti-inflammatory agents, and metabolic disorder therapeutics.
Key Related Patent Families
