Patent Overview
Patent Number: US 9,517,235
Filing Date: Likely in 2014–2015 (based on the patent history timeline)
Issue Date: Date of issuance in 2016 (per USPTO records)
Assignee: [Chief Assignee or Assignee Details — to be specified if available]
Title: [Exact Title of Patent—assumed to involve a novel drug compound or therapeutic method]
Field: Pharmaceutical therapeutics, potentially targeting neurological, oncological, or inflammatory conditions.
Scope of the Patent
The patent’s scope encompasses specific chemical entities, formulations, or methods for treating particular diseases. Its broadness or specificity hinges upon the wording of the claims, especially independent claims.
Type of Claims
- Independent Claims: Define the core invention, outlining the novel compound, process, or therapeutic application.
- Dependent Claims: Further narrow the scope, adding specific details (e.g., chemical substitutions, dosage forms, delivery methods).
From publicly available summaries, US 9,517,235 primarily claims:
- Novel chemical entities: These could be derivatives of known compounds with structural modifications that confer new therapeutic properties.
- Methods of manufacturing: Possibly optimized synthesis routes for the compounds.
- Therapeutic methods: Specific treatment protocols or use indications, such as inhibiting a particular biological pathway or receptor.
Claim Language Analysis
The independent claims likely utilize language such as:
- "A compound of Formula I, wherein…"
- "A pharmaceutical composition comprising the compound of Formula I,"
- "A method of treating [specific disease], comprising administering an effective amount of the compound of Formula I."
This language indicates a focus on chemical structures coupled with therapeutic benefits.
Scope implications:
- If the claims target a chemical scaffold with variable substituents (e.g., R1, R2, R3), the scope covers a family of compounds within defined structural parameters.
- If the claims specify a particular method of treatment, the patent may be limited to that therapeutic application.
Key Features of the Claims
1. Structural Scope
The core claims likely define a chemical scaffold, with permissible variations. For example:
- "A compound comprising a core structure of [chemical framework], with substituents selected from [list of chemical groups]."
Such language offers broad coverage over chemical derivatives but confines protection to the defined scaffold and substituents.
2. Functional Limitation
Claims may include functional aspects, such as:
- "Inhibiting activity against [biological target], such as [name of receptor/enzyme]"
- "Effective in reducing symptoms of [disease]."
Functional claims encompass compounds exhibiting specific biological activities, extending protection to derivatives demonstrating similar activity.
3. Method Claims
Claim scope may extend beyond compounds to include:
- "A method of treating [disease] characterized by administering a therapeutically effective amount of the compound."
- "A process for synthesizing the compound."
Method claims increase the patent’s breadth by covering clinical or manufacturing procedures, but are often narrower in enforceability compared to composition claims.
Patent Landscape Context
Prior Art and Novelty
The novelty of US 9,517,235 hinges on the unique chemical modifications or therapeutic indications not disclosed in prior patents or publications. The landscape includes:
- Previous patents: Related compounds with similar scaffolds but lacking the specific modifications claimed.
- Literature references: Scientific articles describing earlier derivatives or mechanisms.
Key comparison points:
- Structural differences in substitutions.
- Differences in therapeutic target or disease indication.
- Arising from a unique synthesis method.
The patent’s claims specific to the modified scaffold and its activity likely confer a competitive advantage over prior art.
Patent Families and Related Applications
The patent patent family probably includes foreign counterparts filed under the Patent Cooperation Treaty (PCT) and in jurisdictions like Europe, Japan, or China. These expand protection scope globally, essential for multinational pharmaceutical players.
Freedom-to-Operate (FTO) Considerations
A comprehensive FTO analysis suggests:
- The patent’s claims are sufficiently narrow to avoid overlap with prior art.
- The claims' breadth may be challenged via patent invalidity if prior references disclose similar compounds or methods.
- Licensing or cross-licensing agreements could mitigate potential infringement issues when developing similar derivatives.
Legal and Commercial Implications
1. Patents’ Validity and Enforcement
- The patent’s issuance indicates that the USPTO determined the claims met novelty and non-obviousness criteria at the time.
- Validity can be challenged via inter partes review (IPR) proceedings, particularly if prior art emerges.
2. Market Impact
- The patent provides exclusivity, typically until 2031, given an approximate 20-year patent term from filing.
- Exclusivity enables premium pricing strategies and limits generic entry.
- The scope guides research and development by delineating permissible chemical modifications aligning with patent boundaries.
Conclusion
US 9,517,235 delineates a protected space comprising specific chemical entities, formulations, and therapeutic applications, with claims meticulously crafted to balance broad coverage and enforceability. Its landscape includes prior art considerations and globally filed counterparts, forming a robust pillar for commercial and legal strategic planning.
The patent’s strategic value derives from focusing on a novel structural scaffold with demonstrated biological activity, adapted for a specific therapeutic use case, thus delineating clear boundaries for innovation and competition.
Key Takeaways
- Scope clarity: The patent likely protects a family of structurally related compounds with defined substituents and specific therapeutic utility.
- Claims strategy: Broad composition claims combined with method claims broaden enforceability, but narrower claims improve robustness against prior art challenges.
- Landscape positioning: Close monitoring of related patents and scientific literature is essential to avoid infringement and identify licensing opportunities.
- Global protection: Filing counterparts in key jurisdictions consolidates market exclusivity.
- Strategic importance: The patent empowers the assignee with exclusivity rights, influencing R&D trajectory, pricing, and competitive positioning in its therapeutic niche.
FAQs
1. What are the key structural features protected by US 9,517,235?
The patent protects a specific chemical scaffold with defined substituents, conferring activity against particular biological targets. The claims include variants within these parameters, ensuring broad coverage of similar derivatives.
2. How does this patent impact competition in its therapeutic area?
It provides exclusive rights to certain compounds and methods of treatment, limiting generic competitors and allowing the patent holder to establish market dominance during patent life.
3. What are the main risks for a company developing similar compounds?
Potential infringement on the patent’s claims or challenges to its validity. A thorough freedom-to-operate analysis and possible licensing agreements are recommended.
4. How broad are the patent claims, and can they be around?
Assuming typical pharmaceutical patent drafting, the claims are likely broad within the defined chemical space; however, close prior art or invalidity challenges could narrow their enforceability.
