However, there are plenty of trademarks used in the modern world that are as good... no better... than words. I bet if you show a can of Coke with no letters but only the device, better than 90% of the population would know what it is... or at least would know what it is *supposed* to be. The same is probably true of a number of others, like the McDonalds arches.

This might even be true across the globe. I was somewhat surprised at how ubiquitous our Western brands were when I traveled in India. Even somewhat rural India.

So it all depends...
