Questão jurídica principal
Whether the slogan 'we make ideas work' is excluded from trademark protection as common property lacking distinctiveness and being free for use.
Decisão extraída
Yes. The slogan is perceived as a promotional quality claim rather than an indication of commercial origin, and it must remain available to other traders.
Fundamentação extraída
The relevant specialized public understands the English slogan without difficulty as an advertising statement. A sign consisting of a plainly laudatory message has no source-identifying function; possible alternative meanings do not help if the obvious meaning is promotional.
