I traveled to Barcelona last week to attend the International Trademark Association (“INTA”) Annual meeting.

I arrived at the Barcelona Airport the requisite three hours before your international flight.  During my long stay at the Barcelona airport I saw three store signs with ® on them.  They included the following signs:

Although many stores have registered trademarks, the stores usually do not have the ® symbol on the actual store sign.

Have you noticed other store signs with ® included on them? Why don’t more signs have them?
