Is there a minimum time requirement for attorney withdrawal in patent proceedings?

No, there is no longer a minimum time requirement for attorney withdrawal in patent proceedings. The MPEP 2223 states:

“For a practitioner to withdraw from a patent and/or a reexamination proceeding, the Office no longer requires that there be at least 30 days remaining in any running period for response between the approval of a request to withdraw from representation and the expiration date of any running period for response.”

However, practitioners must still provide “reasonable notice” to their clients, which should allow sufficient time for the client to find new representation before any response deadlines.
