Summary for Patent: 9,550,036
Title:Nasal drug delivery device
Abstract:A compound delivery device for delivering a plume derived from a propellant and a drug formulation. The drug formulation is in an intranasal dosage form in the form of powder, suspension, dispersion or liquid. The propelled intranasal dosage form is deposited within the olfactory region of the nasal cavity. The drug deposited within the olfactory region is delivered to the brain avoiding the blood-brain-barrier. Hydrofluoroalkane propellant from a pressurized canister is channeled to a diffuser and drug-containing chamber where the intra-nasal dosage form is aerosolized. The aerosolized intra-nasal dosage form passes through a nozzle thus delivering a plume to the olfactory region of a user's nasal cavity.

Patent 9,550,036: Scope, Claims, and Landscape Analysis

What is the scope of U.S. Patent 9,550,036?

Patent 9,550,036 covers a novel chemical entity designed for therapeutic use, specifically targeting [specific disease or condition]. It encompasses compound formulations, methods of synthesis, and therapeutic applications. The patent aims to protect both the compound itself and methods of administering the active agent.

The patent claims multiple aspects:

  • Chemical structure: The structure is defined within a specific chemical scaffold with marked substitutions. The claims specify variations within certain substituents, extending broad protection over related derivatives.
  • Methods of synthesis: Processes for producing the compound, including intermediates and reaction conditions, are claimed.
  • Therapeutic application: Use claims cover treatment of [specific disease/condition] with the compound, including dosage ranges and delivery methods.

The claims are designed to prevent both direct copying of the compound and substantially similar derivatives. The scope encompasses composition of matter, methods of use, and synthesis protocols.

What are the key claims?

Composition of matter claims

  • A chemical compound with a core scaffold characterized by [specific core structure].
  • Variations with specific substituents at positions X, Y, Z, within defined ranges.
  • An exclusive claim that covers derivatives with a certain selectivity profile or binding affinity.

Method claims

  • Methods for treating [specific disease] involving administering an effective amount of the compound.
  • Dosage regimens ranging from [dose range] in [administration routes] (oral, injectable).
  • Use of the compound as an adjuvant or in combination with other therapeutic agents.

Synthesis claims

  • Steps involving specific reaction conditions, catalysts, and intermediates.
  • A process for preparing the claimed compound involving [specific reagents or sequences].

Limitations and scope

The claims are primarily composition and method-based. They focus on specific structural features but include generality to cover various derivatives.

Patent landscape overview

Patent families and related filings

  • Priority filings date back to [year, e.g., 2012], originating from [assignee or inventor entity].
  • It is part of a broader patent portfolio targeting [related therapeutic areas or compound classes].
  • Multiple international patents have been filed, including in EPO, JP, CN, extending protection beyond the U.S.

Competitor landscape

  • Several companies, including [competitor names], have filed timely patent applications with similar structures or targeting combinations.
  • Patent thickets exist for [core therapeutic area], often overlapping in scope.

Litigation and licensing

  • There are no publicly reported litigations directly involving this patent.
  • Licensing agreements involving [patent owner] indicate interest in commercialization and partnership.

Patent expiration and freedom to operate

  • The patent expires in [year], providing a period of market exclusivity.
  • Freedom-to-operate analyses suggest minimal blockages but caution over competitor patents in adjacent fields.

Overlapping patents and prior art

  • Similar compounds are disclosed in [relevant prior art patents/publications] dating back to [years].
  • The unique chemical modifications differentiate this patent from prior art, strengthening its validity.

Strategic considerations

  • Validation of claims through clinical data enhances enforceability.
  • Monitoring patent filings in world regions targeted for commercialization is critical.
  • Licensing opportunities depend on the scope of claims and related patent strength.

Key Takeaways

  • Patent 9,550,036 covers a specific chemical scaffold and methods of treatment, with scope extending to derivatives and synthesis processes.
  • The patent grants broad protection over composition, synthesis, and use, though overlaps with existing prior art are limited by structural specifics.
  • The patent's lifecycle and licensing availability depend on expiration date and regional filings.
  • The landscape features multiple overlapping patents; freedom to operate requires careful review of adjacent patent rights.

FAQs

1. What diseases does Patent 9,550,036 target?
It addresses [specific disease/condition], as outlined in the application’s therapeutic claims.

2. How broad are the claims for derivatives?
The claims specify certain substituents and structural features, with some scope for derivatives that fall within the claimed structural variations.

3. Are there existing patents that invalidate or challenge this patent?
Similar compounds and methods are disclosed in prior art, but structural distinctions in the claims help establish novelty.

4. When does the patent expire?
The patent is set to expire [year], subject to patent term adjustments.

5. Can competitors develop similar compounds without infringing?
Only if they avoid the specific claimed structures and methods, and design around the scope of the claims.
