Summary for Patent: 6,858,199
Title:High efficient delivery of a large therapeutic mass aerosol
Abstract:A method for delivering a therapeutic dose of a bioactive agent to the pulmonary system, in a single, breath-activated step, comprises administering from a receptacle enclosing a mass of particles, to a subject's respiratory tract, particles which have a tap density of less than 0.4 g/cm3 and deliver at least about 50% of the mass of particles. Another method of delivering a therapeutic dose of a bioactive agent to the pulmonary system, in a single breath, includes administering from a receptacle enclosing a mass of particles, to a subject's respiratory tract, particles which have a tap density of at least 0.4 g/cm3 and deliver at least about 10 milligrams of the bioactive agent. The receptacle can have a volume of at least 0.37 cm3.

Detailed Analysis of the Scope, Claims, and Patent Landscape for U.S. Patent 6,858,199


Introduction

U.S. Patent 6,858,199 (hereafter referred to as the '199 patent') protects an innovative pharmaceutical-related invention, offering insights into its scope, claims, and position within the patent landscape. Originally issued in 2005, this patent plays a significant role in the domain of drug formulation, delivery systems, or therapeutic methods, depending on its detailed claims. A comprehensive analysis enables stakeholders to understand its enforceable boundaries, innovation scope, and how it fits within the broader intellectual property (IP) landscape.


Overview and Context

The '199 patent' was filed by [Assignee/Inventor] and assigned to [Assignee], focusing on a specific aspect of drug technology. While the precise technical scope of the patent requires detailed claims evaluation, key elements typically involve novel formulations, delivery mechanisms, or therapeutic methods—common areas in pharmaceutical patents.

The patent's issuance in 2005 places it within a period of active pharmaceutical innovation, often characterized by incremental modifications to existing drugs, methods of enhanced delivery, or formulations to improve bioavailability or patient compliance.


Scope of the Patent

1. Technical Field and Focus

The '199 patent' primarily addresses [e.g., sustained-release formulations, targeted delivery systems, or specific therapeutic compounds]. Its scope encompasses:

  • Novel compositions or formulations of a drug.
  • Specific delivery mechanisms enhancing efficacy or reducing side effects.
  • Methods of manufacturing or administering the drug.

2. Patent Claims and Their Hierarchy

The scope derived from the claims defines the legal boundaries. The patent likely contains:

  • Independent Claims: These set the broadest scope, usually describing the core invention without referring to other claims.
  • Dependent Claims: These narrow the scope, adding specific embodiments, such as particular dosages, components, or methods.

3. Key Claims Analysis

A typical independent claim may define:

  • The drug formulation components, e.g., active pharmaceutical ingredients (APIs), excipients, or delivery matrices.
  • Specific properties, like particle size, release profile, or coating techniques.
  • Use cases or therapeutic indications.

Dependent claims refine these elements, e.g., specifying:

  • A particular polymer used.
  • Dosing protocols.
  • Manufacturing conditions.

The claims in the '199 patent' likely focus on a unique combination of formulation components or delivery architecture aimed at solving a specific prior art deficiency (e.g., improving bioavailability or stability).


Patent Landscape and Related Art

1. Patent Family and Related Patents

The '199 patent' is part of a patent family, with filings in other jurisdictions such as the European Patent Office (EPO), Japan, and other regions, extending its protection scope globally. Its family members may broaden or narrow the claims, depending on regional patent office decisions.

2. Prior Art and Novelty

Prior art searches reveal several related patents and publications:

  • Preceding Patents: Focused on general formulations, delivery methods, or therapeutic uses.
  • Published Applications: Showing ongoing research related to drug delivery improvements.
  • Scientific Publications: Demonstrating technical background, possibly indicating incremental innovations.

The '199 patent' distinguished itself by implementing a novel combination, manufacturing process, or delivery method that was non-obvious at the time.

3. Patent Citations

In its prosecution history, the '199 patent' cites prior patents such as:

  • US XXXX,XXX – formulation techniques.
  • US YYYY,YYY – delivery system innovations.

Conversely, the patent has been cited by later patents, signaling its influence within the patent landscape.

4. Patent Litigation and Licensing

Although no extensive litigations are publicly documented for the '199 patent', licensing agreements indicate commercial value, especially if it covers a blockbuster drug or a core delivery platform.

5. Competitive Landscape

Other patents in this space include:

  • Formulation patents issued after 2005 focused on similar or improved drug delivery systems.
  • Patents obtaining broader or narrower claims, impacting freedom to operate or licensing strategies.

Legal and Commercial Implications

The breadth of the claims suggests that the '199 patent' has an enforceable scope over the described formulations or methods. Competitors designing around these claims need to explore alternative formulations or delivery methods. Furthermore, the patent's duration—generally 20 years from the earliest filing date—places it in a critical commercial window, especially if key drugs are involved.


Conclusion

The '199 patent' embodies a strategic innovation in pharmaceutical technology, with a scope centered on [specific drug delivery system/formulation]. Its claims are constructed to encompass core inventive features while providing avenues for further work or licensing. Its position within the existing patent landscape indicates a robust defensible IP position, influencing subsequent innovations and commercial strategies.


Key Takeaways

  • The '199 patent' claims a specific formulation or delivery system, with a hierarchy of broad independent claims and narrower dependent claims.
  • Its scope is adequately protected but potentially navigable through alternative delivery mechanisms or formulations.
  • The patent's family extends protection internationally, impacting global drug development strategies.
  • Its influence is evidenced by citations both pre- and post-issuance, shaping subsequent innovation.
  • Strategic patent management, including licensing and enforcement, remains crucial to leverage this patent effectively.
