Is the last known residence always the correct address to provide for a nonsigning inventor?

While the last known residence is often the appropriate address to provide, it’s not always the case. The MPEP states:

‘Ordinarily, the last known address will be the last known residence of the nonsigning inventor.’

However, the key is to provide the address where the inventor customarily receives mail. If this differs from their residence, the mailing address should be provided instead. The goal is to increase the likelihood that the nonsigning inventor will receive any USPTO communications.
