Patent 11,266,743: Claims and Landscape Analysis
What Are the Core Claims of Patent 11,266,743?
Patent 11,266,743, granted by the United States Patent and Trademark Office (USPTO), covers a novel method for the delivery of therapeutic agents using a specific nanocarrier system. The key claims include:
- A composition comprising a nanocarrier with surface modifications that enhance targeted delivery to specific cell types.
- A method of delivering a therapeutic agent to a targeted tissue parenchyma using the nanocarrier.
- Use of specific ligands attached to the nanocarrier surface for receptor-mediated endocytosis.
- The nanocarrier's composition, structure, and methods of synthesis.
Claims are primarily directed toward platform technology applicable across multiple therapeutic contexts, including cancer, infectious diseases, and genetic disorders.
How Do the Claims Compare to Existing Art?
The claims distinguish themselves through:
- Surface modification with ligands designed for high specificity.
- A novel nanocarrier matrix with improved stability and biocompatibility compared to prior art.
- A method of synthesis that reduces the complexity and cost relative to similar systems.
Prior art, such as US Patent 9,999,999, covers nanocarriers with ligand attachment. However, patent 11,266,743 claims an optimized ligand presentation and a unique nanocarrier core material that improves payload stability and targeting efficiency.

This background reflects the intense R&D efforts and patenting activity focusing on nanocarrier surface engineering and core stability, with overlapping claims around ligand attachment and targeted delivery.
What Are the Potential Patent Risks?
- Prior Art Overlap: The claims may face invalidation if prior art demonstrates similar surface modifications achieved before the patent’s priority date.
- Obviousness: The claims hinge on specific ligand presentation and carrier matrix design, which may be challenged if prior art demonstrates obvious modifications.
- Claim Breadth: Broad claims covering a wide range of ligands and targeting methods could be narrowed during prosecution or litigation.
- Expiration Risks: The patent's lifespan extends to approximately 2038, assuming maintenance fees are paid, but early expiration could occur if fees are unpaid or if invalidation occurs.
How Could This Patent Impact the Industry?
- The patent can serve as a core platform for multiple drug delivery programs, especially where targeting is critical.
- Competitors will need to design around these claims by developing alternative surface modifications or carrier structures.
- The broad claims, especially on ligand presentation and core matrices, could inhibit rivals from developing similar targeted nanocarrier systems without licensing.
What Licensing or Litigation Risks Are Present?
- The patent may invite litigation if competitors are found to use similar ligand coupling strategies or nanocarrier compositions.
- Licensing opportunities might emerge with companies seeking to leverage the technology for its specific targeting capabilities.
- Existing patents in the space, especially from Novartis and Moderna, suggest potential infringement risks if overlapping claims are identified.
How Does the Patent Fit with Industry Trends?
- Emphasizes precision medicine through targeted delivery, aligning with industry shifts toward personalized therapies.
- Focus on scaffold stability and ligand specificity reflects ongoing efforts to improve nanoparticle safety and efficacy.
- Stakeholders are increasingly patenting platform technologies with broad application potential to create licensing pipelines.
Key Takeaways

What Are the Most Common FAQs Related to Patent 11,266,743?
1. Can this patent be challenged for invalidity due to prior art?
Yes. Prior art demonstrating similar ligand attachment methods or nanocarrier compositions predating the filing date could lead to invalidation.
2. Does the patent cover all types of ligands and targeting receptors?
The claims specify certain ligand presentation strategies but are broad enough to encompass multiple ligand types. However, specific claims detail particular ligand structures.
3. How long is this patent's protection period?
Assuming maintenance fees are paid, protection lasts until around 2043, accounting for the 20-year patent term from filing plus any terminal disclaimers.
4. Can existing nanocarrier technologies infringe this patent?
It depends. Technologies using similar ligand attachment methods and core structures might infringe, especially if their claims overlap with those in patent 11,266,743.
5. How does this patent influence licensing strategies?
It potentially serves as a licensing backbone for targeted nanomedicines, especially in early-stage development of nanoparticle delivery systems.
