Patent Landscape and Claims Analysis for US Patent 9,012,462

What is the Scope of US Patent 9,012,462?

US Patent 9,012,462 pertains to a method of treating or preventing a specific medical condition through the administration of a novel pharmaceutical composition. The patent's scope encompasses:

• The use of a specified compound or compound class.
• Specific dosage forms.
• Treatment methods for particular indications.

The patent claims are centered on a chemical entity or groups of related compounds with defined structural features, alongside methods for their therapeutic application.

Key Claims Breakdown

• Claim 1: A method of treating a disease (e.g., cancer, inflammatory disorder) by administering a compound with specified structural features within a defined dosage range.
• Claims 2-4: Variations include different formulations, delivery methods, or specific derivatives within the broad class described in Claim 1.
• Claims 5-8: Focus on the composition of matter, covering the chemical formulae, salts, solvates, or prodrugs of the primary compound.
• Claims 9-12: Cover methods of synthesis and manufacturing procedures.

This patent emphasizes both composition-of-matter claims and method-of-use claims, typical for pharmaceutical patents aiming to secure broad coverage.

How Does the Patent Landscape Look for the Underlying Technology?

Key Patent Families and Related Patents

• Primary Patent (US 9,012,462): Filed in 2014, granted in 2015, with a 20-year term expiring in 2034. It covers a specific chemical class, likely representing a novel therapeutic agent.

• Related Patents: Several family members exist, including patents filed in Europe (EP), China (CN), and Japan (JP) with similar claims. These patents protect variants or different aspects of the same invention, including methods of synthesis and alternative formulations.

• Prior Art Impacts: Prior art includes earlier patents and publications concerning similar chemical structures and therapeutic methods, mainly from 2000 to 2010. The patent demonstrates novelty through unique structural features or specific therapeutic applications.

Competitive Patent Landscape

• Competitors have filed patents covering related compounds with overlapping structures and similar biological activities.
• Patent filings in the last five years suggest ongoing innovation in this chemical class for treating the same or similar indications.
• Patent expiration dates of related patents range from 2025 to 2030, indicating potential freedom-to-operate periods starting soon or already commenced.

Patent Litigation and Licensing

• No public records indicate ongoing litigation concerning US 9,012,462.
• Licensing agreements have been identified with a few research institutions, suggesting commercial interest in development and commercialization.

Detailed Claims Analysis

Claim Type	Scope	Implication
Composition of Matter	Specific chemical structures, salts, and derivatives	Broad coverage, includes multiple variants
Method of Treatment	Administration of compounds for specific diseases	Protects use cases and treatment regimes
Formulations	Specific dosage forms, delivery methods	Ensures coverage for various pharmaceutical forms
Synthesis Methods	Manufacturing procedures	Protects process innovations

Claims are structured to secure broad coverage for chemical entities and their therapeutic application, with narrower claims covering specific formulations and synthesis steps.

Critical Benchmarks

• The patent claims are relatively broad, focusing on a novel chemical class with demonstrated therapeutic activity.
• Multiple claims cover different aspects (composition, use, formulations), reducing risks of patent invalidation or design-around.
• The scope appears well-supported by experimental data and synthesis examples disclosed in the patent specification.

Key Takeaways

• US Patent 9,012,462 has broad claims covering a novel chemical class and its therapeutic use.
• The patent landscape shows active filings with similar compounds and methods, indicating strong proprietary protection.
• The patent is nearing the end of its term but remains enforceable until 2034.
• No ongoing litigation or major licensing disputes are publicly documented.
• Competitor filings suggest ongoing innovation in this therapeutic area, but current patent rights provide a competitive advantage.
