Trademarks only apply to _related_ goods and services.

> it is illegal to rhyme trademarks

Not necessarily. The standard is "confusingly similar" or "likelihood of confusion." There are many words and phrases which rhyme incidentally where trademark protection would not apply or where damages would not be granted.

The confusion also has to apply specifically to the brand or the product. If your trademark fails to be associated with either of those things it can be invalidated.
