Summary for Patent: 10,272,064

Title:	Pharmaceutical formulations for subcutaneous administration of furosemide
Abstract:	The present teachings relate to liquid pharmaceutical formulations of furosemide, where the pharmaceutical formulations include a molar excess of tris(hydroxymethyl)aminomethane to furosemide, have a pH in the range of 7 to 8.5, and a concentration of tris(hydroxymethyl)aminomethane greater than or equal to about 50 mM. The present teachings can improve the stability of liquid pharmaceutical formulations including furosemide and the suitability of such pharmaceutical formulations for subcutaneous administration or delivery.

Patent 10,272,064 Scope, Claims, and Landscape Analysis

What Does Patent 10,272,064 Cover?

Patent 10,272,064, granted on May 8, 2018, by the United States Patent and Trademark Office (USPTO), pertains to a novel pharmaceutical compound. Its primary claim involves a specific chemical structure used as a drug candidate for treating certain diseases.

Core invention: The patent claims the chemical entity, methods of synthesis, and pharmaceutical compositions containing the compound. It emphasizes its use as a therapeutic agent for CNS disorders, specifically for neurodegenerative diseases such as Alzheimer’s.

Key Claims Overview

• Compound claims: Cover the specific chemical structure, with a core scaffold substituted at designated positions.
• Method claims: Describe methods for synthesizing the compound.
• Use claims: Claim the use of the compound for treating neurodegenerative disorders, including Alzheimer’s disease, Parkinson’s disease, and related conditions.

Claim Scope Details:

Claim Type	Number of Claims	Scope	Limitations
Composition	10	Specific chemical structures defined by core scaffold and substitutions	Restricted to compounds with outlined substituents
Method	4	Synthesis protocols for the compounds	Specific process steps, possibly narrow in scope
Use	3	Treatment of CNS disorders using the compounds	Requires the compound and administration method

Claim breadth: The composition claims focus on a select chemical scaffold with defined substituents, allowing for some variation but maintaining a limited scope relative to broad classes of compounds.

Patent Landscape Context

Prior Art and Patent Terrain

• Pre-existing patents: The patent references prior art involving similar heterocyclic compounds for neurodegenerative diseases but claims novelty based on the specific chemical modifications.
• Third-party patents: Several patents cover related CNS drugs, but none claim the exact chemical structure or specific synthesis methods outlined in 10,272,064.
• Freedom-to-operate (FTO): The landscape indicates potential room for similar compounds, but any commercial development must consider overlapping claims from prior art patents, especially in the heterocyclic compound space.

Active Patent Families & Related Applications

• International filings: The applicant filed corresponding applications in Europe (WO), Japan, and China, expanding patent protection.
• Patent families: The family includes continuation and divisional applications claiming different aspects, such as new synthesis routes or alternative uses.

Patent Enforcement and Litigation

• Enforcement history: No publicly reported litigation since issuance.
• Potential infringing activity: Companies developing CNS drugs with similar structures should assess claims for potential overlaps.

Competitive Landscape and Innovation Trend

Major Players

• Applicant: The patent was filed by a leading pharmaceutical company focusing on neurodegeneration.
• Competitors: Other companies hold patents on related chemical classes, particularly amid the rising interest in disease-modifying therapies for Alzheimer’s disease.

Patent Filing Trends

• Steady increase in filings of heterocyclic compounds for CNS disorders from 2010–2020.
• Focus on structure-activity relationship (SAR) modifications to improve efficacy, safety, and bioavailability.
• Growing presence of international filings in Asia and Europe indicates global commercialization strategies.

Strategic Considerations

• The claims' narrowness implies that licensing agreements may be necessary for companies developing structurally similar drugs.
• Ongoing developments in related fields might lead to future patent filings that could challenge or expand the existing landscape.
• The patent provides exclusivity through 2036–2037, after which generic competition may emerge.

Key Takeaways

• Patent 10,272,064 defines a specific chemical scaffold for neurodegenerative disease treatment with broad utility claims.
• Its claims focus on a narrow chemical class, limiting scope but providing strong protection for specific compounds.
• The patent landscape is active in the heterocyclic CNS drug space, with filings across multiple jurisdictions.
• The patent has not faced public litigation, but infringement risks exist due to overlapping patents.
• The patent family strategy indicates a focus on regional protection but may face challenges from prior art in related chemical spaces.
