These applications were published in 1943, despite not becoming patents. The MPEP states: Applications vested in the Alien Property Custodian during World War II were published in 1943 even though they had not become patents.

It’s important to note that these are not patents and should not be referred to as such. Instead, they should be designated as A.P.C. published applications.
