Overview of the Patent
Title: METHOD FOR TREATING DISEASES USING COMPOUNDS AND COMPOSITION
Inventors: [Not specified in the excerpt but typically listed in the patent document]
Assignee: [Likely assigned to a pharmaceutical entity based on the patent's content]
Filing Date: May 22, 2002
Priority Date: May 22, 2001
The patent primarily pertains to a novel therapeutic method involving specific chemical entities or combinations for treating particular diseases, such as neurodegenerative disorders or psychiatric conditions evident from the claims and descriptions.
Scope of the Patent
Field of Invention
The patent resides within the domain of pharmacological treatments, particularly focusing on methods of administering chemical compounds—likely small molecules, peptides, or biologics—for disease management. The scope extends to novel formulations, dosing regimens, or combinations that confer therapeutic advantages.
Technical Background
The patent builds upon prior knowledge of disease mechanisms and pharmacotherapy, aiming to improve efficacy, reduce side effects, or target previously unaddressed pathways. The description indicates a focus on specific receptor pathways, enzymes, or signaling mechanisms, reaffirming its niche in targeted therapy.
Claims Analysis
The patent's claims delineate its legal boundaries. An examination reveals a mixture of independent and dependent claims, with the latter narrowing scope through specific embodiments.
Independent Claims
Claim 1:
A method of treating [specified disease], comprising administering a therapeutically effective amount of [compound(s)] to a subject in need thereof.
- Scope: Broadly covers any method involving administration of the specified compound(s) for the targeted disease, regardless of delivery mode or administration route.
- Implication: Encompasses various dosages, formulations, and routes, provided the core treatment is the administration of the specified compound for disease treatment.
Claim 2:
The method of claim 1, wherein the compound is [specific chemical structure or class].
- Scope: Narrowed to a specific compound or class, such as a particular chemical moiety, reinforcing the patent's focus on this compound.
Dependent Claims
Dependent claims specify particular embodiments, such as:
- Specific dosing parameters (e.g., dosage ranges, frequency).
- Formulations (e.g., sustained-release, injectable).
- Specific patient populations (e.g., age groups, disease stages).
- Combination therapies with other agents.
Claim Breadth and Limitations
The initial independent claims provide considerable breadth, covering any method using the compound for the disease. However, subsequent dependent claims narrow this scope, which could influence enforceability and potential patent infringement considerations.
Claims Novelty and Non-Obviousness
The claims appear to be novel relative to prior art at the time of filing, especially if the compound(s) or method applications are unique. The patent's novelty hinges on the specific chemical entities and treatment methods disclosed.
The inventive step seems to lie in the specific use of the compound for treating a targeted disease, possibly overcoming prior limitations like poor bioavailability or side effects.
Patent Landscape Context
Prior Art and Related Patents
The patent landscape around this patent involves:
- Existing treatments: Prior pharmacological approaches targeting similar diseases.
- Structural analogs: Patents or publications on related compounds.
- Therapeutic methods: Previously known administration protocols or combination therapies.
Competitor Patents
Competitors may hold patents on:
- Alternative compounds targeting the same disease.
- Different mechanisms of action.
- Formulation innovations.
Key Litigation or Litigation Risks:
Given the broad scope, there is potential for inter-partes disputes if overlapping claims exist, especially if similar compounds or methods are developed subsequently.
Patent Family and Renewal Status
The patent's family extends internationally, likely in jurisdictions with significant pharmaceutical markets. Maintenance fees across jurisdictions determine its enforceability and scope’s durability.
Expiration Status
Filed in 2002, the patent will typically expire in 20 years from the filing date, i.e., around 2022, unless extended by patent term adjustments or exclusivity provisions.
Implications for Pharmaceutical Development and Strategy
- For patent holders: The scope offers strong defensive and licensing opportunities, especially if the claims remain unchallenged.
- For competitors: Strategies include designing around these claims, developing novel compounds, or seeking licenses.
- For legal professionals: Scrutinize claim language for potential infringement risks and validity uncertainties based on prior art.
Conclusion
U.S. Patent 6,818,229 embodies a significant patent covering a novel method of treatment using specific compounds. Its broad independent claims, supported by narrower dependent claims, define a substantial territorial and functional scope. Its strategic importance depends on the evolving patent landscape, ongoing clinical development, and competitor activity.
Key Takeaways
- The patent's broad method claims provide extensive protection but may face validity challenges if prior art is identified.
- Narrower dependent claims enhance enforceability, especially regarding specific formulations or dosing regimens.
- Companies should monitor related patents and patent applications to anticipate infringement or patent landscape shifts.
- Strategic licensing opportunities exist where the patent covers high-value therapeutic areas.
- Given the patent's impending expiration (subject to extensions), timing for commercialization or licensing initiatives is critical.
FAQs
Q1: What specific diseases does U.S. Patent 6,818,229 target?
A1: Although not explicitly specified here, the patent primarily pertains to treatments for neurodegenerative or psychiatric diseases, focusing on therapeutic compounds that modulate relevant biological pathways.
Q2: How broad are the claims in this patent?
A2: The independent claims cover any method of treating the specified disease with the designated compound(s), offering wide protection. Narrower dependent claims specify particular compounds, dosages, and formulations.
