ICA has been a well-known trademark for a long time. The sign which is used today was registered as a trademark back in 1964.
Figurative and collective mark
The trademark ICA is a figurative mark, as the text has been produced in a particular typeface. It is also a collective mark, as it is used by several companies in an association.
The foundation for ICA was laid in 1917, when there was the idea to merge and form joint purchasing groups. The trademark ICA was registered for the first time in 1949 and since then the trademark's scope of protection has expanded a number of times.
