Unified Patent Court procedure guides

When is the deadline for claimant's correction of deficiency or written comments on a preliminary objection?

Claimant uses 14 days to correct the identified deficiency or lodge written comments, measured against service of notification of the Preliminary objection. The response period does not extend the defendant's separate Statement of defence period. The ordinary source period remains a conditional fixed boundary, not a variable period merely because this page withholds a calculation. This guide supplies no calculated final date.
