Patent No. EP3341015 (titled "Enhanced Depletion Of Targeted Cells With Cd47 Blockade And An Immune Costimulatory Agonist") was filed by The Board OF Trustees OF The Leland Stanford Junior University on Aug 26, 2016. The application was issued on Dec 27, 2023.
A method for targeted cell depletion in cancer treatment, comprising administering a combination of agents that modulate immunoregulatory signaling pathways. The method includes blocking CD47 activity to prevent immune evasion by tumor cells, and simultaneously activating immune costimulatory molecules such as CD137 to enhance immune cell function. The combination of agents synergistically enhances targeted cell depletion, particularly in cancer treatment where tumor cells exploit immune evasion mechanisms to survive.

Patent oppositions filed by competitors challenge the validity of a granted patent. These oppositions are typically based on claims of prior art, lack of novelty, or non-obviousness. They are a key part of the process for determining a patent's strength and enforceability.
