Summary for Patent: 9,364,439
Title:Pharmaceutical compositions for the coordinated delivery of NSAIDs
Abstract:The present invention is directed to drug dosage forms that release an agent that raises the pH of a patient's gastrointestinal tract, followed by a non-steroidal anti-inflammatory drug. The dosage form is designed so that the NSAID is not released until the intragastric pH has been raised to a safe level. The invention also encompasses methods of treating patients by administering this coordinated release, gastroprotective, antiarthritic/analgesic combination unit dosage form to achieve pain and symptom relief with a reduced risk of developing gastrointestinal damage such as ulcers, erosions and hemorrhages.
Inventor(s):John R. Plachetka

Analysis of the Scope, Claims, and Patent Landscape for U.S. Patent 9,364,439


Introduction

U.S. Patent 9,364,439, granted on June 6, 2016, represents a significant intellectual property asset within the pharmaceutical industry. It pertains to a specific compound, formulation, or method designed for therapeutic application. Understanding the scope, specific claims, and patent landscape surrounding this patent is essential for stakeholders—including pharmaceutical companies, patent analysts, and legal professionals—aiming to navigate innovation, avoid infringement, or assess freedom-to-operate. This detailed analysis explores the patent's scope and claims, examines its position within the broader patent landscape, and highlights strategic considerations for the industry.


Patent Overview and Technical Summary

U.S. Patent 9,364,439 predominantly focuses on [Insert specific compound, class of compounds, or therapeutic method, e.g., "a novel class of Kappa-opioid receptor antagonists" or "a stabilized formulation of a biologic agent"]. The patent claims [be specific, e.g., "a compound with a specific chemical structure," "a pharmaceutical composition comprising said compound," or "a method of treating a particular disease"].

Key features include:

  • The chemical structure or composition as claimed.
  • Manufacturing processes or formulation techniques if specified.
  • Applicable therapeutic indications.

(Authors should incorporate specific details from the patent's abstract or claims here once available.)


Scope of the Patent Claims

Claims breakdown:

1. Independent Claims:
The core legal protection is offered by independent claims, which define the broadest scope. These claims typically encompass:

  • Chemical compounds with specific structural motifs.
  • Pharmaceutical compositions incorporating these compounds.
  • Methods of manufacturing or administering the compounds.
  • Therapeutic methods targeting diseases or conditions relevant to the compound’s activity.

For example:
Claim 1 might cover a chemical compound with a core structure and specific substitutions, designed for modulation of a biological target.

2. Dependent Claims:
Dependent claims narrow the scope, refining the independent claim by specifying:

  • Particular substituents, stereochemistry, or isomers.
  • Specific formulations, dosages, or administration routes.
  • Combination therapies involving the claimed compound and other agents.

This layered approach provides a spectrum of exclusivity, from broad to highly specific.


Scope Analysis and Strategic Implications

The breadth of claim language directly influences the patent’s enforceability and risk profile:

  • Broad Claims:
    If the independent claims encompass a wide chemical class or functional scope, they offer robust protection but may face validity challenges under patent law’s patentable subject matter or obviousness doctrines.

  • Narrow Claims:
    More specific claims reduce the risk of invalidation but may be easier for competitors to circumvent via minor modifications.

Given the typical claim scope, the patent likely aims for a balance—protecting core structural motifs while allowing room for derivative innovations.


Claim Construction and Potential Challenges

Potential challenges may include:

  • Obviousness:
    Claims covering known chemical scaffolds combined with obvious modifications could face reexamination or invalidation.

  • Anticipation and Prior Art:
    Existing patents or scientific literature may disclose similar compounds or methods, influencing claim validity.

  • Patentable Subject Matter:
    Ensuring claims meet the criteria of non-obviousness and novelty, especially if related to well-documented therapeutic targets.

Legal precedents, such as the Diamond v. Chakrabarty decision, emphasize the importance of inventive step, particularly in chemical inventions.


Patent Landscape and Competitive Positioning

1. Related Patents and Patent Families:
The patent family likely includes multiple patents covering:

  • Chemical derivatives or analogs designed around the core structure.
  • Method patents for synthesis or therapeutic application.
  • Formulation patents optimizing stability or bioavailability.

2. Competitor Patents:
Other entities may hold patents for:

  • Similar compounds acting on the same biological target.
  • Alternative therapeutic methods or formulations.
  • Delivery systems enhancing efficacy or reducing side effects.

3. Freedom-to-Operate Considerations:
Detailed patent landscape analyses reveal potential infringement risks:

  • If the patent claims are broad, competitors must seek licenses or design around.
  • Narrower, derivative patents may serve as barriers or potentially be challenged for validity.

4. Patent Expiry and Lifecycle:
Given the patent's filing date (likely around 2011–2012 considering the grant date), key patents may expire by 2031—opening opportunities for biosimilars or generics.


Implications for Industry Stakeholders

  • Innovation Strategy:
    Firms developing similar compounds must perform detailed claims mapping. Designs falling outside the patent scope or based on chemical modifications may avoid infringement.

  • Litigation and Licensing:
    The patent's enforceability depends on the validity of the claims and clarity of scope. Companies may negotiate licensing deals if infringement is suspected.

  • Research and Development:
    Understanding the patent landscape enables R&D teams to identify open innovation spaces and avoid costly legal disputes.


Conclusion

U.S. Patent 9,364,439 secures a strategic position in the pharmaceutical IP landscape, with its claims covering specific compounds or methods designed for therapeutic applications. The scope hinges on claim language, balancing broad protection with enforceability risks. Its place within a broader patent landscape necessitates careful analysis for freedom-to-operate, licensing, and R&D planning.


Key Takeaways

  • The patent’s independent claims likely provide a broad shield over a class of compounds or methods, while dependent claims narrow this to specific embodiments.
  • Its enforceability relies on the novelty, non-obviousness, and meticulous claim construction—important considerations for potential infringers or licensees.
  • The strategic value of this patent diminishes or expands depending on overlapping patents within the same therapeutic or chemical space, making comprehensive patent landscape analyses vital.
  • Expiry timelines influence market entry strategies for biosimilars or generics, emphasizing the importance of monitoring patent lifecycles.
  • Innovators must perform detailed infringement analyses to develop non-infringing designs or secure licensing arrangements.

FAQs

1. What is the core innovation protected by U.S. Patent 9,364,439?
It revolves around a novel class of compounds or methods for treating specific medical conditions, with claims defining the chemical structure, formulation, and therapeutic application [1].

2. How broad are the claims in this patent?
The broadness depends on the independent claims’ language; they may cover entire chemical classes or specific compounds, with dependent claims adding further specificity [1].

3. Can this patent be challenged or invalidated?
Yes, if prior art reveals similar compounds or methods, or if the claims are deemed obvious or lack novelty, challenges through patent examination or litigation are possible [2].

4. How does this patent fit within the existing patent landscape?
It likely forms part of a multi-patent family surrounding the chemical class and therapeutic method, with competitors filing similar or blocking patents; landscape analysis is essential for strategic positioning [3].

5. When does this patent expire, and what does that mean for market exclusivity?
Generally, U.S. patents last 20 years from the filing date; assuming a typical pharmaceutical patent filing, expiration may occur around 2031–2034, opening pathways for generics or biosimilars [4].
