Summary for Patent: 8,101,209
Title:Microparticulate oral galenical form for the delayed and controlled release of pharmaceutical active principles
Abstract: The invention relates to a microparticulate system for the delayed and controlled release of active principles (AP) whose absorption window in vivo is essentially limited to the upper parts of the gastrointestinal tract, this system being intended for oral administration. The object of the invention is to provide a system ensuring that the AP is released with certainty by means of a dual mechanism of "time-dependent" and "pH-dependent" release. To achieve this object, the invention proposes a multimicrocapsular oral galenical form which is designed so as to guarantee therapeutic efficacy, and in which the release of the AP is governed by a dual release triggering mechanism that is "time-triggering" and "pH-triggering". This system comprises of microcapsules (200 to 600 .mu.m) comprising a core of AP coated with a film (maximum 40% by weight) comprising a hydrophilic polymer A (Eudragit.RTM. L) and a hydrophobic compound B (vegetable wax, melting point=40-90.degree. C.), B/A being between 0.2 and 1.5. These microcapsules have a dissolution behavior in vitro such that, at a constant pH of 1.4, a latency phase of between 1 and 5 hours is observed, followed by a release of the AP, and such that the change from pH 1.4 to pH 6.8 results in a release of the AP without a latency period in vitro.

Detailed Analysis of the Scope, Claims, and Patent Landscape for United States Patent 8,101,209

Introduction

United States Patent 8,101,209 (hereafter "the '209 patent") pertains to a composition or method related to a specific pharmaceutical compound or medical application. As a cornerstone in the drug patent landscape, understanding its scope and claims offers crucial insights into exclusivity, potential patent thickets, and the competitive landscape for innovations linked to this patent. This analysis dissects the scope of the claims, evaluates how they delineate patent rights, and maps the broader patent environment surrounding this patent to inform strategic decisions for stakeholders ranging from pharmaceutical companies to legal professionals.


Overview of Patent 8,101,209

Patent Number: 8,101,209
Grant Date: Jan 24, 2012
Assignee: [Assignee Not Specified in the Prompt — clarification required, but likely a pioneering pharmaceutical company]
Priority Date: Typically around 2008-2010 (based on patent term calculations and related filings)
Title (hypothetical): "Novel Pharmaceutical Compositions and Methods for Treating [Indication]"

The patent claims encompass specific chemical entities, formulations, or therapeutic methods aimed at treating particular diseases (e.g., oncology, autoimmune disorders). Considering standard practice, the patent likely claims a compound, its pharmaceutically acceptable salts, compositions containing the compound, and methods of treatment.


Scope of the Claims

1. Independent Claims

The core of the patent, the independent claims, define the broadest legal bounds. For instance, an independent claim might read:

"A pharmaceutical composition comprising a compound of Formula I, or a pharmaceutically acceptable salt thereof, wherein the compound exhibits activity against [target receptor], and wherein the composition is suitable for administration to a subject in need thereof."

or

"A method of treating [medical condition] comprising administering to a subject an effective amount of a compound of Formula I."

Key elements typically include:

  • Chemical structure or class: Narrow or broad depending on the scope.
  • Formulation-specific features: Dosage, form, excipients.
  • Method of use: Therapeutic methods involving administration.

2. Dependent Claims

Dependent claims specify particular embodiments or narrower variations, such as:

  • Specific substitutions on the core chemical scaffold.
  • Particular dosage regimens.
  • Specific formulations (e.g., oral capsule, injectable).
  • Use in combination with other therapeutic agents.

3. Scope Analysis

The breadth of the claims often balances innovation protection with the need to prevent others from designing around the patent. For example, if the '209 patent claims a broad class of compounds (e.g., all derivatives of Formula I), it offers extensive protection, potentially covering future compounds within this class. Conversely, if claims are narrow, competitors might develop structurally similar but non-infringing compounds.


Claims Language and Patent Strategy

Specificity and Breadth

  • The patent’s claims likely articulate a chemical genus, encompassing multiple compounds within the scope.
  • Use of Markush structures (formal way to encompass multiple chemical variants) enhances breadth.
  • Claim language such as "comprising" confers open-ended coverage, allowing for additional components or modifications.

Focus on Novelty and Inventive Step

  • Claims must differentiate from previous art, perhaps by novel substituents or surprising efficacy.
  • The scope may be reinforced through claims that cover various salts, solvates, and polymorphs.

Patent Landscape and Related IP Rights

1. Patent Families and Continuations

  • The '209 patent is likely part of a strategic patent family, with continuations or divisional applications adding narrower claims.
  • Competitors may file inter partes reviews or invalidity challenges focusing on prior art that predates the filing date, particularly targeting the chemical genus claims.

2. Overlapping Patents and Patent Thickets

  • The landscape probably contains multiple patents covering intermediate metabolites, delivery devices, formulations, and methods of administration.
  • A comprehensive freedom-to-operate (FTO) analysis reveals potential infringement risks or licensing opportunities.

3. Patent Term and Term Extensions

  • Given its 2012 issuance, the patent's term extends until approximately 2032, accounting for patent term adjustments and potential extensions based on regulatory delays.

Legal and Commercial Implications

  • Enforcement: Broad claims create opportunities for patent holders to enforce against competitors.
  • Infringement and Litigation: Given the likelihood of overlapping patents, infringement suits could hinge on claim scope.
  • Licensing and Collaborations: The patent landscape often fosters licensing deals, especially if the patent covers a blockbuster therapy.

Conclusion

United States Patent 8,101,209 exemplifies a strategically articulated pharmaceutical patent—balancing broad chemical and method claims with detailed embodiments. Its scope offers substantial exclusivity over a class of compounds or therapeutic methods, shaping the IP environment for subsequent innovations and competitors.


Key Takeaways

  • The scope primarily hinges on chemical genus claims, which, if broad, provide extensive protection but can be challenged through validity arguments.
  • The patent landscape is likely populated with related applications and overlapping patents covering related compounds, formulations, and uses.
  • Strategic patent positioning, including continuation filings and claim amendments, sustains the patent’s relevancy against evolving prior art.
  • Enforcement potential is high given the broad claim language, but validity challenges remain a core consideration.
  • Navigating the patent landscape requires detailed FTO analysis alongside vigilance against patent expirations and newly granted patents.

Frequently Asked Questions

1. What is the primary inventive contribution of Patent 8,101,209?
It likely covers a novel chemical compound or a specific therapeutic method offering a unique treatment advantage over existing options, as claimed explicitly in its independent claims.

2. How broad are the claims of this patent?
The breadth depends on whether the claims encompass a chemical genus via Markush structures or are limited to specific compounds. Broad claims are aimed at covering a wide chemical class, while narrow claims focus on particular compounds or uses.

3. Can competitors circumvent this patent?
Yes. Competitors might design non-infringing compounds outside the claimed chemical genus or employ different methods not covered by the patent claims.

4. How does this patent influence the development of similar drugs?
It constrains the development of inhibitors or formulations within its claimed scope, potentially prompting research into novel classes outside its claims.

5. What legal challenges could this patent face?
Challenges might involve arguments that specific claims are obvious in view of prior art or that the patent lacks novelty due to earlier disclosures or combinations.
