Can a petition under 37 CFR 1.47(a) be filed for multiple unavailable inventors?

Yes, a petition under 37 CFR 1.47(a) can be filed for multiple unavailable inventors. The MPEP 409.03(b) states:

‘Where there are joint inventors, each nonsigning inventor must be petitioned for separately, even if more than one nonsigning inventor is unavailable.’

This means that while a single petition can cover multiple unavailable inventors, the petition must address each inventor individually, providing specific information and evidence for each one’s unavailability.
