Brazilian inventor of caller ID struggles to collect royalties
Brazilian inventor vows to sue mobile phone operators after patents battle left him broke

Fifteen years after he patented caller ID technology, Brazilian inventor Nelio Jose Nicolai is no millionaire.
Quite the opposite: out of work since 1984, the co-inventor of the ubiquitous tool is still fighting to collect royalties.
"This revolutionised cellular telephony," Nicolai, 72, proudly said of his BIMA technology, recalling the rapturous welcome it received in Canada and the United States.
In 1996, the inventor received an award from the World Intellectual Property Organisation and a year later - after a five-year wait - he finally secured a patent in his homeland.
He then approached domestic mobile phone operators to claim his rights to royalties - and ran into a wall.
"One of the companies told me 'Go to court, maybe your great-grandchildren will collect something'," the he said. "So I decided to defend the rights of my great-grandchildren."
