There are cases that the Applicant/Agent gets the access code before the application is registered in WIPO DAS.
TDA Offices (USPTO, EPO, KIPO, JPO, CNIPA, EUIPO) provide the DAS access code to the applicant directly to the user and according to the DAS service regulations, the access code should be given to the user, after registration in DAS.
But somehow in some cases, it can happen that the applicant receives the access code before the registration was done.
The reasons for this could be:
DAS support can inform the OFF of the situation (the document is being required by an OSF), final registration in DAS will depend on the resolution of the issue that might be affecting the file in the OFF.
