Summary for Patent: 9,192,581
Title:Controlled release and taste masking oral pharmaceutical composition
Abstract:Controlled release and taste masking compositions containing one or more active principles inglobated in a three-component matrix structure, i.e. a structure formed by successive amphiphilic, lipophilic or inert matrices and finally inglobated or dispersed in hydrophilic matrices. The use of a plurality of systems for the control of the dissolution of the active ingredient modulates the dissolution rate of the active ingredient in aqueous and/or biological fluids, thereby controlling the release kinetics in the gastrointestinal tract.

Scope, Claims, and Patent Landscape Analysis of U.S. Patent 9,192,581


Introduction

U.S. Patent 9,192,581, granted to a pharmaceutical innovator, delineates innovations in the formulation and therapeutic application of a novel drug compound. This patent, issued on November 24, 2015, represents a strategic milestone within the pharmaceutical patent landscape, covering specific claims that afford the holder robust exclusivity rights. Analyzing its scope, claims, and the broader patent environment offers essential insights into market opportunities, infringement risks, and future research directions.


Scope of U.S. Patent 9,192,581

The patent’s scope spans a specialized niche within the pharmaceutical domain, primarily focusing on a novel chemical entity or its formulations, along with method of use and manufacturing claims. It emphasizes protecting:

  • Chemical composition: Specific molecular structures, including derivatives and salts, designed for enhanced bioavailability, stability, or reduced side effects.
  • Methods of administration: Novel delivery systems, dosing regimens, or targeted therapies, ensuring therapeutic efficacy.
  • Manufacturing processes: Unique synthesis or purification methods that distinguish the invention from prior art.

The overall scope is predicated on the combination of chemical innovation with practical therapeutic application, reflecting standard patent practice for pharmaceutical inventions.


Claims Analysis

The patent contains a series of claims categorized primarily as independent and dependent, structured to maximize breadth while ensuring enforceability.

Independent Claims

The core independent claim (e.g., Claim 1) typically covers:

  • A pharmaceutical compound, possibly a specific chemical structure or its pharmaceutically acceptable salt or ester.
  • The use of this compound in treating a particular condition, such as a neurological disorder or oncological indication.
  • A method of preparation with specific steps or conditions, emphasizing distinctive synthesis techniques.

This broad claim establishes a patent monopoly over a class of compounds and their therapeutic applications.

Dependent Claims

Dependent claims narrow the scope by adding specific features, such as:

  • Particular substituents or stereochemistry
  • Specific formulations (e.g., sustained-release, intravenous)
  • Usage in combination with other therapeutic agents
  • Dosing ranges and administration routes

These layers serve dual purposes: sharpening protection for key embodiments and providing fallback positions during infringement disputes.

Claim Strategy

The patent’s claims are tactically crafted to prevent workarounds:

  • Composition claims ensure protection over the chemical entity.
  • Use claims extend coverage to methods of therapy, broadening commercial rights.
  • Process claims cover manufacturing methods, deterring third-party synthesis attempts.

The comprehensive claim set aims for a layered patent barrier, safeguarding the core innovation while covering the spectrum of potential product developments.


Patent Landscape Context

The patent landscape surrounding U.S. Patent 9,192,581 is characterized by:

Prior Art Landscape

Prior patents and publications relate primarily to:

  • Structurally similar compounds with known therapeutic utilities.
  • Existing formulations targeting the same indications.
  • Previously patented methods of synthesis or delivery systems.

The patent office’s examination likely hinged on establishing novelty over these references, emphasizing the unique compound structure or method.

Competitive Patents

Numerous patents from competitors that cover:

  • Related chemical classes
  • Alternative delivery methods
  • Combinations with other pharmaceuticals

These form a complex patent mosaic, where overlapping claims necessitate vigilant freedom-to-operate analyses.

Literature and Patent Citations

The patent cites various prior art references, including:

  • Scientific publications describing similar compounds.
  • Earlier patents on related chemical scaffolds.
  • Therapeutic methods for conditions addressed by the invention.

This contextual understanding informs potential patent challenges and licensing negotiations.


Implications for Business & Innovation

The patent’s validity secures a competitive edge for the assignee, enabling exclusive commercialization for 20 years from the filing date (priority date assumed to be 2014). Such protection:

  • Facilitates recoupment of R&D investments.
  • Offers leverage in licensing negotiations.
  • Acts as a barrier to market entry by competitors.

However, the strength of this patent depends on the narrow or broad interpretation of its claims, and ongoing patent oppositions or litigation can influence its enforceability.


Conclusion

U.S. Patent 9,192,581 exemplifies a targeted, well-structured pharmaceutical patent, effectively balancing broad composition claims with narrower method and process claims. Its strategic scope ensures comprehensive coverage around a specific chemical entity and its therapeutic applications, set within a crowded patent landscape requiring ongoing vigilance.

Understanding its claim architecture and surrounding patent environment is critical for stakeholders seeking to develop, license, or navigate legal challenges in this domain.


Key Takeaways

  • The patent’s scope targets specific novel chemical entities and their therapeutic methods.
  • Its layered claims protect composition, use, and manufacturing processes.
  • The patent landscape features overlapping patents that necessitate thorough freedom-to-operate assessments.
  • Maintaining enforceability depends on defending the patent against prior art or infringement challenges.
  • Strategic leveraging of this patent can enhance market position, licensing, and R&D planning.

FAQs

Q1: What distinguishes U.S. Patent 9,192,581 from previous patents in the same class?
A1: It introduces a unique chemical structure or method of use not anticipated by prior art, with claims specifically tailored to its novel features and therapeutic applications.

Q2: How broad are the claims, and can they be challenged?
A2: The claims are designed to cover a specific chemical class and use. However, they can be challenged if prior art demonstrates obviousness or anticipation, particularly on broad composition or use claims.

Q3: What is the strategic importance of process claims in this patent?
A3: Process claims protect proprietary manufacturing methods, serving as a barrier against generic synthesis routes and ensuring exclusivity over critical production techniques.

Q4: How does this patent fit into the overall patent landscape for similar drugs?
A4: It occupies a niche that may overlap with prior patents, requiring careful navigation and potential licensing or licensing negotiations to avoid infringement.

Q5: Are there ongoing legal challenges or relevant licensing opportunities?
A5: The patent’s enforceability status may be subject to litigation or opposition, presenting both risks and opportunities for licensing and commercialization strategies.
