I own two trademarks here and guess what, not even the domain name I managed to reclaim, the owner uses the same name for a different type of business which I don't own the exclusivity rights.
Brazilian IP law is one of the most free in the word and among many things, software cannot be patented, non-specific, generic ideas are not even evaluated for a patent. Music can be freely played and shared unless you are doing it commercially.
This is why I can't even download bass tabs on most sites, RIAA managed to block brazilians from 40% of youtube, etc.
There are several cases here where an inventor receives no money at all and a lot of people get rich with it's invention, because of this law.
I think it's too loose and also our courts are terrible, there is a case from a guy that waited 20 years to win a first instance sue against several phone companies and after losing it they just appealed... so he will have to wait 10 more years, and probably die or go bankrupt.
