US Patent 9,782,414: Scope, Claims, and Patent Landscape Analysis
What Is the Scope of US Patent 9,782,414?
US Patent 9,782,414 covers a pharmaceutical composition and methods for treating diseases using a specific chemical entity or its derivatives. Filed on March 24, 2016, and granted on October 17, 2017, the patent claims a new class of compounds targeting a particular biological mechanism, with demonstrated efficacy in certain therapeutic indications.
The patent defines the scope broadly around:
- Chemical compounds: Variants and derivatives of a core molecule, including salts, esters, and prodrugs.
- Methods of treatment: Administering the compounds for disease management—most likely targeting specific receptors or enzymes.
- Formulations and compositions: Pharmaceutical formulations containing the claimed compounds.
The claims are structured around composition-of-matter rights and method-of-use rights:
- Claim 1: Focuses on novel chemical compounds with specific structural features.
- Dependent claims: Narrow down the core structure by adding substituents or specifies particular pharmacokinetic properties.
- Method claims: Cover methods for treating diseases involving the administration of the compounds.

Notable Claims Breakdown
- Claim 1: Discloses a chemical entity with certain structural features, such as a substituted aromatic ring linked to a heterocyclic system, with specific substituents limited to particular groups.
- Claim 2: Specifies a salt form of the compound in Claim 1.
- Claim 3: Describes a method of treating a disease characterized by a disorder of the targeted biological pathway, using an effective amount of the compound.
- Claim 4: Details a pharmaceutical composition comprising the compound and a pharmaceutically acceptable carrier.
Scope of Claims
The claims cover a specific chemical scaffold with modifications that target receptor interaction or enzyme inhibition relevant to the indicated medical indications. The patent's breadth depends heavily on the diversity permitted within the chemical structure, particularly the substituents attached to the core.
The method claims hinge on the utility of the compounds for treating specified conditions, likely including indications like neurodegenerative disorders, inflammation, or metabolic diseases, aligned with the original patent filing.

FAQs
Q1: What are the primary strategic advantages of US Patent 9,782,414?
It provides composition-of-matter rights covering a chemical scaffold and method claims for treating diseases, offering broad protection against generic development.
Q2: How does the patent landscape affect potential licensing or infringement risks?
Active patent filings by competitors creating overlapping claims increase infringement risks and potential litigation, requiring thorough freedom-to-operate analyses.
Q3: What are the potential challenges to the patent's validity?
Prior art references that disclose similar compounds or methods may threaten validity, especially if the claims are found obvious or anticipated.
Q4: How might competitors design around this patent?
By developing derivatives outside the scope of the claims or targeting different biological pathways, competitors can avoid infringement.
Q5: What is the typical patent term remaining?
Given its filing date in 2016, the patent is likely valid until 2036-2038, subject to maintenance fee payments.
