Please ask the invitee to check in the Spam/Junk folder. The email comes from InQuartik and should look like below:
If the invitee has not created a Patentcloud account yet, there will be a "Click to Register" button instead.
Once the invitee has created an account, he/she can select PV from the Product Menu to view the Project List.
If there is no email invitation even in the Spam/Junk folder, please contact us at firstname.lastname@example.org.
