Claims Analysis
U.S. Patent 11,771,667 comprises 15 claims, which can be segmented into independent and dependent claims.
1. Independent Claims
-
Claim 1: Describes a method of administering a therapeutic agent comprising steps involving administering an initial dose followed by at least one subsequent dose, wherein the doses are delivered via a specialized device enabling controlled-release and targeted delivery to specific tissues.
-
Claim 2: Defines a device assembly configured for the method claimed in Claim 1, including features such as a programmable controller, localized injection features, and sensing components for monitoring drug levels or tissue response.
-
Claim 3: Encompasses a composition comprising the therapeutic agent in a formulation optimized for controlled-release and stability within the device.
2. Dependent Claims
Dependent claims elaborate on specific embodiments, such as:
- Use of particular materials (e.g., bioresorbable polymers) to construct the device (Claims 4-6).
- Specific dosing schedules, intervals, and volumes (Claims 7-9).
- Target tissue characteristics, such as vascularization levels or receptor density (Claims 10-12).
- Integration with patient monitoring systems, including mobile applications or implantable sensors (Claims 13-15).
3. Scope of Claims
The claims' breadth indicates a focus on:
- A combination of device configuration and method of administration.
- Specific dosing protocols that aim to optimize pharmacokinetics.
- Use of particular formulations to enable controlled, localized delivery.
While the claims are somewhat narrowly tailored regarding device features, they retain flexibility through dependent claims, allowing adaptation to different therapeutic agents and clinical scenarios.
Patent Landscape and Competitive Position
1. Prior Art Context
The landscape surrounding drug delivery patents includes numerous filings covering controlled-release formulations, injectable devices, and targeted delivery systems. Key players such as Boston Scientific, Medtronic, and emerging biotech firms have extensive patent portfolios in related modalities. Notably, the patent appears to carve out a niche by combining specific device features with a defined administration protocol, setting it apart from more generic delivery patents.
2. Overlap and Potential Conflicts
A review of recent patent publications indicates overlapping concepts around programmable infusion devices and localized drug delivery in the context of implantable devices. However, the specificity of the claimed methods and device features in 11,771,667 mitigates direct conflicts, provided third-party adaptations do not infringe on the unique combination of features.
3. Opportunities for Licensing and Litigation
Given the high relevance in targeted therapy markets, the patent holder could capitalize through licensing agreements with device manufacturers and pharmaceutical companies. Conversely, competitors may seek design-around strategies, such as alternative device configurations or delivery protocols that avoid the patented combinations.
4. Patent Family and Portfolio Strategy
It appears that this patent forms part of a broader family with related filings in Europe and Asia, reinforcing global protection. Its strategic inclusion in a portfolio targeting precision medicine aligns with recent industry trends favoring co-optimized delivery systems and combination therapies.

FAQs
Q1: Can this patent be licensed for use in conjunction with existing biologic therapies?
A: Yes, if the biologic therapy aligns with the scope—particularly if it benefits from controlled, localized delivery via the patented device and method—the patent holder may offer licensing. Negotiations would depend on the specific therapeutic and intended application.
Q2: Does the patent protect the design of the device or only the method of administration?
A: It primarily claims both—covering a specific device configuration and the method of administration involving that device. Some claims are device-independent, while others specify device features.
Q3: Are there notable ways to circumvent this patent?
A: Potential design-arounds include modifying device features, altering the administration protocol, or using alternative delivery mechanisms not covered explicitly by the claims. Strategic R&D can explore these avenues.
Q4: How does this patent compare with prior art in the drug delivery space?
A: It advances prior art by integrating programmable device features with specific dosing protocols, offering a more comprehensive approach than earlier independent patents focusing solely on one aspect.
Q5: What are the patent’s expiration considerations?
A: Assuming maintenance fees are paid, the patent's expiration is expected around 2042, providing a long-term protective horizon for licensed applications.
