Excuse my ignorance, but how this help to find a suitable solution? Ether your workflow can handle those patches correctly by honoring the overprint settings or not. If not because it is not supported, you might run into issues where it is the fault of the workflow because the output was messed up.

if you create a PS and use distiller, you can control OPM by activating the "Illustrator Overpint Mode" in the Advanced-tab.
Another way where it can come from:
a text is defined in black (DeviceGray). In order to have this text overprint another CMYK element, it has to be converted to ether DeviceCMYK or Separation Black, since DeviceGray can not overprint DeviceCMYK. If the element only gets converted to CMYK and set to overprint but OPM is 0, it is still knocking out.
Besides that I do not know of any other way to directly control OPM. I would have to do some research.
