Radiolabeling prostate-specific membrane antigen (PSMA) ligands with suitable radioactive isotopes, such as 68Ga, 90Y, and 177Lu, under mild reaction conditions (e.g., room temperature) and for short periods of time (e.g., 3 to 30 minutes), while still obtaining quantitative radiochemical yields, wherein said radiolabeled PSMA is suitable for the diagnosis or therapy of prostate cancer.

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.
