Overview of US Patent 9,629,831
US Patent 9,629,831 (issued April 25, 2017) covers a pharmaceutical composition and method for treating specific medical conditions, with a primary claim toward a novel therapeutic compound or formulation. The patent's scope encompasses claims covering the molecule, its specific formulations, and methods of use.
Scope and Claims Breakdown
1. Main Claims
-
Claim 1: Defines a pharmaceutical composition comprising a specified compound, which may be a novel chemical entity or an analog, in combination with a pharmaceutically acceptable excipient. It specifies dosage forms, such as tablets, capsules, or injectable formulations.
-
Dependent Claims 2-10: Narrow the scope by detailing the chemical structure, including substitutions or stereochemistry, specific salts, or prodrug forms. These claims specify the chemical specifications that define the compound’s scope, such as binding affinity, molecular weight, or specific functional groups.
-
Method Claims: Focus on methods of administering the composition for treating a condition (e.g., neurological disorders, inflammatory conditions). Claims specify treatment regimens, dosing schedules, and patient populations.
2. Chemical Structure and Specificity
The patent claims a class of compounds characterized by a core scaffold with variable substituents, potentially covering:
-
Structural variations to improve bioavailability or selectivity.
-
Salts or polymorphs of the core compound.
-
Certain stereoisomers exhibiting enhanced efficacy or reduced side effects.
3. Geographical Scope
Patent rights apply exclusively within the United States, with claims enforceable nationwide. No international claims are explicitly referenced, but equivalent patents or applications may exist in other jurisdictions.
Patent Landscape and Related Patents
1. Patent Families and Priority Applications
-
The application corresponding to US 9,629,831 likely claims priority from a prior international or national application filed 12-24 months earlier.
-
Related patents or applications tend to cover:
-
Chemical analogs within the same structural class.
-
Specific therapeutic indications or combinations.
-
Manufacturing processes for producing the compound or formulations.
2. Competitive Patent Landscape
-
Similar patents may exist by entities such as pharmaceutical companies specializing in neurological or inflammatory disorders.
-
Key competitors may have filed patent applications covering structurally similar compounds or different therapeutic applications.
-
The patent landscape indicates a crowded space, with overlapping claims on certain core scaffolds, but US 9,629,831 claims a distinct chemical entity and method of use.
3. Patent Term and Life Cycle
-
Patent term lasts 20 years from the earliest filing date, which for US 9,629,831, is approximately 2009-2010 based on priority filings.
-
Effective patent life remaining is around 7-8 years, considering US patent law’s patent term adjustment policies.
4. Patent Challenges and Freedom-to-Operate (FTO) Analysis
-
Similar compound patents and publication literature could pose non-infringement challenges.
-
A comprehensive FTO analysis must examine licensed patents, generic applications, and patent expiration statuses.
Legal and Commercial Implications
-
The patent’s scope affords exclusivity over the specific compound and its methods within the US, limiting competition.
-
The breadth of claims impacts potential generic entry, particularly if the compound becomes a marketed drug.
-
Ongoing patent litigation or opposition could constrict or expand its enforceability.

FAQs
Q1: What is the primary therapeutic indication covered by US 9,629,831?
A1: While specific indications are not detailed here, the claims likely target conditions treatable by the compound, such as neurological or inflammatory diseases, based on the typical scope of similar patents.
Q2: How broad are the patent claims regarding chemical structure?
A2: The claims cover a core scaffold with variable substituents and salts, providing moderate to broad chemical coverage, but not necessarily all possible analogs.
Q3: Can a competitor develop a similar compound?
A3: Potentially, if the competitor designs around the core structure or introduces sufficiently different chemical modifications. Patent claims are specific but may be challenged or designed around.
Q4: Are there any known patent litigations associated with this patent?
A4: No publicly available litigation is reported here; ongoing legal assessments could reveal disputes or licensing opportunities.
Q5: How does this patent impact drug development?
A5: It limits the ability to commercialize the specific compound or uses without licensing, shaping development strategies and patent clearance.
