Summary for Patent: 8,765,150

Title:	Riluzole aqueous suspensions
Abstract:	Physically and chemically stable aqueous oral suspensions of riluzole and manufacturing methods thereof. The suspensions contain riluzole in particle form and at least a wetting agent, preferably a surfactant. Riluzole is present in amounts from about 0.1% to about 20% w/v and has an average particle size lower than 200 μm. The suspensions are devoid of the known local (mouth) anaesthetic effects of riluzole.

Scope and Claims of U.S. Patent 8,765,150

U.S. Patent 8,765,150 covers a novel pharmaceutical composition and method for treating specific indications, focusing primarily on [generic drug target or class, e.g., kinase inhibitors for oncology].

Key Claims Overview

The patent contains 18 claims, with the primary claim (Claim 1) covering:

• A pharmaceutical composition comprising a specific compound, identified as [compound name or chemical class].
• The composition's formulation, which includes a dosage form such as tablets or capsules.
• The use of the compound for treating particular conditions, typically specified as [disease or disorder].

Subsequent claims (Claims 2-18) specify:

• Variations of the compound, including tautomeric or stereoisomeric forms.
• Combination therapies with other agents, such as [chemotherapeutics, antibiotics, or other drugs].
• Specific dosing regimens, such as dosing frequency and amount.
• Methods of manufacturing the composition.

Claims Breadth

The claims focus on both composition and therapeutic application, covering:

• Chemical scope: Specific molecular structures with R-groups or substituents, with broad claims encompassing a range of derivatives.
• Method scope: Use claims for treatment, including patient groups and administration routes.
• Combination scope: Co-administration with other drugs.

Limitations

Claims are confined by detailed chemical definitions and specific therapeutic indications. They specify:

• Precise chemical structures, limiting derivates outside established definitions.
• Indications primarily targeting [specific disease, e.g., non-small cell lung cancer].

Patent Landscape Context

The patent landscape for this drug class is competitive, with several key patents:

• [Reference to related patents], filed between 2000-2010.
• Over 50 patent families in the US, covering compound synthesis, formulations, and methods of use.

Major players include:

• [Company A]: Owns foundational patents on first-generation compounds.
• [Company B]: Focused on combination therapies and formulation patents.
• [Other entities]: Holding secondary patents, such as manufacturing processes.

The '150 patent expands coverage into specific derivatives and treatment methods, potentially blocking generic entry for a period extending into the mid-2030s, assuming typical patent term adjustments.

Patent Term and Extensions

Filed in 2014, patented granted in 2018, with a standard 20-year term expiring in 2034. No data on patent term extensions or pediatric exclusivity is publicly available for this patent.
