Patent Law FAQ
This FAQ answers all your questions about patent law, patent procedure, and the patent examination process.
No, this specific requirement does not apply to all patent applications. The MPEP clearly states:
‘[Editor Note: This MPEP section is not applicable to applications filed on or after September 16, 2012.]’
This means that the requirement to provide the last known address of a nonsigning inventor is only applicable to pre-AIA applications filed before September 16, 2012, under 37 CFR 1.47. For applications filed on or after this date, different rules may apply, and applicants should consult the current USPTO guidelines or seek legal advice.
