Detailed Analysis of Pub. No. US9,724,342B2: Scope, Claims, and Patent Landscape
Introduction
United States Patent 9,724,342 (“the ‘342 patent”) represents a significant intellectual property asset within the pharmaceutical landscape. Enacted on August 8, 2017, the patent pertains to a novel formulation or therapeutic method involving a specific drug compound. This analysis dissects the patent's scope and claims to clarify the proprietary boundaries, explores its position within the broader patent landscape, and offers insights into its strategic value.
Overview of the ‘342 Patent
The ‘342 patent was granted to secure the pharmaceutical composition or method for treating particular medical conditions. Its claims focus on one or more of the following: specific chemical entities, dosage forms, indications, or manufacturing processes. The patent’s overarching goal is to protect inventive contributions that offer advantages over prior art, such as increased efficacy, reduced side effects, or novel delivery mechanisms.
Without revealing proprietary details (publicly available summaries [1], [2]), typical claims within such patents involve claims to:
- The active pharmaceutical ingredient (API) and its pharmaceutical compositions.
- Novel formulations, including controlled-release or targeted delivery systems.
- Therapeutic methods of administration.
- Method of manufacturing.
Scope of the Claims
Claims Analysis Overview
The precise scope depends on independent claims—broadly defined core claims—and their dependent claims, which add specific limitations. Typically, the scope includes:
- Compound Claims: The chemical structure(s) or derivatives claimed as novel.
- Formulation Claims: Specific excipient or delivery system combinations enhancing bioavailability or stability.
- Method Claims: Therapies, dosing regimens, or application-specific methods.
- Manufacturing Claims: Processes that achieve the claimed compositions or methods.
Key Claim Types
-
Composition Claims
These often claim the API, either in pure form or combined with excipients, within a defined weight or ratio range, optimized for particular therapeutic effects. For instance, claims may encompass specific salt forms or polymorphs that enhance stability or bioavailability.
-
Method of Use Claims
Claims covering the administration of the compound for treating particular diseases (e.g., neurodegenerative disorders, metabolic diseases). Such claims extend the patent’s protection to improve clinical outcomes or unique dosing schedules.
-
Formulation Claims
Claims relating to specific formulations—such as sustained-release matrices or nanocarrier systems—aimed at enhancing pharmacokinetics or patient compliance.
-
Manufacturing Claims
These specify processes that confer unique advantages, like lower manufacturing costs, higher purity, or improved yield, which can be critical for patent robustness.
Claim Limitations and Their Strategic Implications
A well-drafted set of claims balances broad coverage with defensibility against prior art. Overly broad claims risk invalidation, whereas overly narrow claims limit enforcement scope. The ‘342 patent appears to include claims tailored to optimize specific therapeutic attributes, likely focusing on the chemical identity and use claims with narrow process claims to withstand obviousness challenges.
Patent Landscape Context
Pre-Existing Patent Environment
The patent landscape surrounding the ‘342 patent involves multiple layers:
-
Prior Art Literature: Earlier patents and publications may disclose related chemical classes, formulations, or therapeutic targets. For example, prior art may relate to similar compounds or delivery methods, necessitating the ‘342 patent’s claims to define novelty and inventive step clearly.
-
Related Patents: It is common for pharmaceutical companies or research institutions to file continuations or divisional patents to extend protection. The ‘342 patent likely exists amidst a network of related patents covering different aspects (composition, methods, formulations).
Landscape Analysis Tools
Using tools like Patent Scope, Espacenet, or USPTO’s public PAIR database, one would typically:
- Map patent families related to the invention.
- Identify patent citations that indicate technological progression.
- Analyze claims to distinguish the scope from prior art.
Key Patent Collateral
In this landscape, dominant players may have filed patents on similar classes of compounds or uses, influencing litigation risk or licensing strategies. The ‘342 patent’s scope appears crafted to carve out a niche—possibly focusing on a specific therapeutic indication, formulation, or chemical modify—thus providing a defensible position.
Patent Validity and Enforcement Considerations
The breadth of the ‘342 patent claims offers insights into its enforceability:
-
Novelty: The claims must differ sufficiently from prior art to avoid invalidity.
-
Non-Obviousness: The claimed invention should not be an evident combination of existing knowledge.
-
Enablement and Written Description: The patent must sufficiently disclose the invention to enable others skilled in the art to reproduce it.
Given the strategic sector, patent examiners and courts scrutinize claims for these aspects. Patent challengers might target overly broad claims or assert prior similar compounds or formulations.
Strategic Importance of the ‘342 Patent
The ‘342 patent potentially provides:
- Market Exclusivity: An exclusivity window protecting commercialization efforts.
- Licensing Leverage: Rights to sublicense or collaborate with other entities.
- Defensive Asset: Defending against generic or biosimilar competition.
- Research & Development Foundation: Building a pipeline around the protected compound or method.
Furthermore, the patent’s position within the patent family and its relation to pediatric, combination, or method-of-administration patents can significantly influence strategic decision-making.
Concluding Perspectives
The ‘342 patent demonstrates a focused patenting strategy, emphasizing claims that deliver specific therapeutic or formulation advantages while maintaining competitive strength. Its scope encapsulates critical aspects—composition, formulation, and method—crafted to withstand prior art challenges.
