Story highlights Apple loses right to iPhone trademark in Brazil

Brazil patent regulator affirms local tech firm owns exclusive rights through 2018

Brazilian firm Gradiente Eletronica debuted "iphone Neo One" December 2012

Apple has endured past trademark problems in China, Japan, U.S.

When it comes to buying an iPhone in Brazil, consumers have one extra option that the rest of us do not.

There's the "iPhone" made by the California tech giant Apple. Then there's the "iphone" made by the Brazilian firm Gradiente Eletronica and, perhaps in a slap to Apple, runs on rival Android's operating system.

And it's going to stay that way pending any future appeal or settlement.

On Thursday, Brazil's Institute of Industry Property (INPI), the country's main patent regulator, ruled that Apple holds no exclusive right to use the iPhone moniker to market its mobile phones. If Apple continues to use the iPhone name, Gradiente can sue.

INIP added that Gradiente Eletronica holds exclusive rights to the trademark though 2018 after having registered for the iPhone name in 2000. Apple only unveiled its iPhone name in 2007
