Patent 10,047,033: Claims and Landscape Analysis
What Are the Core Claims of Patent 10,047,033?
Patent 10,047,033, granted by the United States Patent and Trademark Office (USPTO) on August 14, 2018, primarily focuses on a novel method and apparatus involving targeted delivery of therapeutic agents. The patent claims define a system that employs specific ligand-receptor interactions to enhance drug efficacy, primarily in cancer therapy.
Main Claims Breakdown:
-
Claim 1: Describes a method for delivering a therapeutic agent directly to a target cell, involving a ligand attached to a carrier, where the ligand exhibits high affinity for a receptor overexpressed on target cells.
-
Claim 2: Specifies that the ligand can be an antibody fragment, peptide, or other binding molecule. The receptor is overexpressed in cancerous tissues compared to normal tissues.
-
Claim 3: Details the carrier as a nanoparticle, liposome, or other vesicular system that encapsulates the therapeutic agent.
-
Claim 4: Discloses that the system allows controlled release of the drug upon binding to the target receptor.
-
Claims 5-10: Cover various embodiments, including specific ligand-receptor pairs, types of therapeutic agents (chemotherapeutics, nucleic acids), and delivery routes.
Critical Evaluation:
The claims integrate established principles of targeted drug delivery, such as ligand-receptor specificity and nanocarrier encapsulation, but they combine these into a specific system designed for enhanced targeting. They cover a broad range of ligand types and carrier systems, aiming for flexibility in application.
Patent Scope and Breadth:
The claims are broad but focused on the novelty of ligand-targeted nanocarrier systems. While similar systems exist, the specificity in receptor targeting to certain overexpressed receptors (e.g., HER2, EGFR) adds a layer of innovation.

How Does Patent 10,047,033 Compare to Priority Art?
Similarities:
- Utilizes ligand-receptor interactions for targeting.
- Incorporates nanocarriers such as liposomes or nanoparticles.
- Emphasizes controlled release mechanisms.
Differences:
- Focuses on specific receptor overexpression in particular cancer types.
- Combines multiple carrier and ligand types under a single patent umbrella.
- Claims broad versatility in therapeutic agent types, from small molecules to nucleic acids.
The claims sit at the intersection of existing nanocarrier and ligand-targeting patents but provide an integrated approach, claiming a broader scope than most prior art.
Market Relevance and Commercial Potential
Targeted delivery systems share high commercial value, particularly in oncology, where overexpressed receptors like HER2 or EGFR are well-characterized. The patent’s broad claims support potential licensing across:
- Chemotherapy enhancement.
- Nucleic acid-based therapeutics.
- Personalized medicine modalities.
Seminal competitors include patents from Novartis, Genentech, and AstraZeneca, which hold overlapping claims or similar targeting methods.
Regulatory and Patent Strategy Implications
The broad claim scope offers substantial freedom to operate for current patent holders. However, third-party developers must evaluate whether their receptor-targeting strategies or nanocarrier compositions infringe specific claims, especially those related to ligand types and delivery vectors.
Strategically, patent holders should pursue continuous patent prosecution to cover emerging targeting ligands and carrier systems, extending protection into combinatorial approaches.
