Patent Overview
Title and Assignees
United States Patent 10,925,844 is assigned to Flamel Ireland Ltd and pertains to gamma-hydroxybutyrate (GHB) compositions with enhanced pharmacokinetics, particularly in the fed state[5].
Priority Date and Grant Date
The priority date for this patent is March 1, 2019, indicating when the initial application was filed. The patent was granted on a later date, marking the official recognition of the invention.
Scope of the Patent
Invention Description
The patent describes compositions of gamma-hydroxybutyrate, a compound used in various medical applications, including the treatment of narcolepsy and cataplexy. The invention focuses on improving the pharmacokinetics of GHB when administered in the fed state, which is crucial for maintaining consistent therapeutic effects regardless of the patient's dietary status.
Technical Details
The patent outlines specific formulations and methods for preparing these compositions. This includes details on the types of excipients, the manufacturing process, and the resulting pharmacokinetic profiles. The improved pharmacokinetics ensure that the drug is absorbed and metabolized consistently, even when taken with food.
Claims Analysis
Independent and Dependent Claims
The patent includes a set of claims that define the scope of the invention. Independent claims stand alone and define the broadest aspects of the invention, while dependent claims build upon the independent claims and provide additional specificity.
- Independent Claims: These typically describe the core elements of the invention, such as the composition itself, the method of preparation, and the specific improvements in pharmacokinetics.
- Dependent Claims: These claims further detail the invention by specifying particular aspects, such as the types of excipients used, the dosage forms, and any specific manufacturing steps.
Claim Construction
Understanding the construction of these claims is essential for determining the patent's scope. Claim construction involves interpreting the language of the claims to identify the exact boundaries of what is protected. This process is critical in patent litigation and licensing agreements[4].
Patent Landscape
Prior Art and Related Patents
To understand the novelty and non-obviousness of the invention, it is necessary to review prior art and related patents. Tools like the USPTO's Patent Public Search and the Common Citation Document (CCD) can help identify prior art cited by various patent offices, ensuring that the invention is distinct from existing technologies[1].
Global Dossier and International Patents
The Global Dossier service provides access to file histories and related applications from participating IP offices, helping to identify similar patents filed globally. This is particularly important for understanding the international patent landscape and potential licensing or infringement issues[1].
Competitors and Market Impact
Analyzing the patent landscape also involves identifying competitors who may be working on similar technologies. This can be done by searching patent databases such as those provided by the European Patent Office (EPO), Japan Patent Office (JPO), and the World Intellectual Property Organization (WIPO)[1].
Economic and Legal Implications
Patent Monetization and Licensing
The patent can be monetized through licensing agreements, allowing other companies to use the patented technology. This is a common strategy for non-practicing entities (NPEs) and can be a significant revenue stream for the patent owner[4].
Patent Litigation
Understanding the claims and scope of the patent is crucial for avoiding or defending against patent infringement lawsuits. The exclusive rights granted by the patent can restrict competition, but they also provide a legal basis for enforcing these rights against infringers[4].
Practical Applications and Future Directions
Clinical Implications
The improved pharmacokinetics of GHB compositions can have significant clinical implications, such as enhanced therapeutic efficacy and reduced side effects. This can lead to better patient outcomes and increased market acceptance of the drug.
Research and Development
The patent's focus on formulation and pharmacokinetics opens avenues for further research and development. Future studies could explore additional excipients, dosage forms, or delivery mechanisms to further enhance the drug's performance.
