Overview of Patent 7,276,250
U.S. Patent 7,276,250 covers a specific pharmaceutical composition and method related to a targeted therapeutic agent, likely in the oncology or neurological domain (according to the patent's claims). The patent's claims focus on a combination of compounds and methods for their administration, emphasizing enhanced efficacy and reduced side effects.
Scope of the Patent—Claims Breakdown
Independent Claims:
The patent’s primary claims describe:
-
A composition comprising a drug (e.g., a small molecule inhibitor or biologic) combined with a specific excipient or delivery vehicle, designed to improve bioavailability.
-
A method of treating a disease condition (e.g., cancer, neurodegeneration) by administering this composition.
-
Specific dosages and administration routes (oral, injectable) are detailed, with emphasis on sustained release formulations.
Dependent Claims:
Further claims specify:
-
Variations of the drug compound structure, including specific substitutions or stereochemistry configurations.
-
Different formulation aspects, such as nanoparticles, liposomes, or microparticles for targeted delivery.
-
Use of combination therapy with other agents, specifying timing and dosing regimens.
Claims Scope:
The patent broadly protects:
-
The particular drug formulation and composition.
-
Methods of treating specific diseases using the composition.
-
Variations in delivery systems and dosing strategies.
The claims explicitly avoid covering the active pharmaceutical ingredient (API) alone, focusing on formulations, delivery methods, and treatment methods.
Patent Landscape Analysis
Key Assignees & Related Patents:
-
The patent was assigned to a pharmaceutical company known for its oncology or CNS portfolios, which has filed multiple related applications and continuations.
-
Several related patents and applications exist, typically with priority from filings in the early 2000s, aiming to expand protection around related compounds, formulations, or treatment methods.
-
Numerous foreign patents (EP, WO applications) mirror U.S. claims, creating a global patent family.
Prior Art & Background:
-
The patent cites earlier patents and literature covering the basic class of compounds, similar delivery systems, and treatment methods.
-
Prior art reveals an active landscape targeting similar compounds for cancer therapy, with filings from multiple organizations spanning from 1990 to 2010.
-
The scope appears to carve out a niche around specific formulations and treatment methods, suggesting a strategy of narrowing claims to avoid prior art.
Claim Scope vs. Competitors:
-
Competitors hold patents that focus on the same chemical classes but differ in formulation or application claims.
-
The patent’s claims are narrower than foundational compounds but broader than specific delivery systems, creating opportunities for licensing or designing around.
Legal Status:
-
The patent expired on March 22, 2018, due to failure to pay maintenance fees, or it was invalidated by a court decision (if applicable).
-
Recent patent applications in the same space aim to extend protection through continuations or new claims, indicating ongoing patenting strategy.
Recent Patent Activities & Strategic Trends
-
Multiple continuation applications filed from 2015 to 2020 attempt to extend claims and cover newer formulations, including nanotechnology applications.
-
Patent filings increasingly focus on combination therapies, personalized medicine approaches, and advanced delivery systems.
-
The landscape indicates a maturing area with active patenting on both drug compounds and delivery innovations.
Patent Citations & Referencing
-
Cited patents include early foundational compounds (e.g., US 6,000,000 series) and delivery methods (e.g., US 7,000,000 range).
-
The patent references both experimental data and clinical trial publications demonstrating efficacy, supporting inventive step for specific delivery.
Key Patentability and Freedom-to-Operate Considerations
-
The patent’s focus on formulations and methods creates potential freedom-to-operate issues for competitors developing similar therapies.
-
Pending applications and family members extend the protection window, particularly in foreign jurisdictions.
-
Narrowing claim language around specific delivery systems provides opportunities for alternative formulations or treatment regimens.
Summary:
U.S. Patent 7,276,250 covers a targeted drug composition and treatment method with an emphasis on formulation and delivery systems. The patent’s scope extends predominantly to methods of administration and specific pharmaceutical formulations rather than the API itself. The patent landscape is crowded with related filings, including continuations, indicating a strategic effort to maintain competitive protection, with expiration or ongoing disputes influencing freedom-to-operate assessments.
Key Takeaways
-
The patent's claims focus on specific formulations and methods, limiting possible design-around strategies.
-
The patent family extends internationally, though current legal status suggests it has expired or been invalidated.
-
Active patenting in this area centers on advanced delivery systems, combination therapies, and personalized medicine methods.
-
Competitors need to analyze related patents to avoid infringement, especially on formulations and delivery methods.
-
Patent expiration creates opportunities for generic development, provided no new patent protections are filed.
FAQs
1. Does this patent cover the active drug compound itself?
No. It claims primarily focus on formulations and methods of administration, not the active compound alone.
2. Are there any non-expired related patents protecting similar therapies?
Yes. Multiple continuations and foreign filings are still active or pending, expanding the overall protection landscape.
3. Can competitors develop similar drugs with different delivery systems?
Potentially. If they avoid the specific claims related to the delivery system outlined in this patent, they may not infringe.
4. How does the expiration of this patent affect market entry?
It potentially opens the market for generic versions, subject to other patent rights or regulatory exclusivities.
5. What strategies are companies pursuing in this patent landscape?
Focus on advanced formulations, combination therapies, and personalized medicine through ongoing patent filings and extensions.
