It's a classic "David vs. Goliath" battle. A small dental surgery in Malmö, Sweden up against a multi-million dollar video game giant.
Sadly, in this case, Goliath won.
Nintendo has taken legal action to force the surgery in question to change its name - which was previously "Wii Smile". Before you cynically assume that the firm was established in order to benefit from the enormous popularity of Nintendo's console, it should be noted co-owner Christer Wihlborg picked the moniker because his surname starts with "Wi" and there are two owners.
Sadly for him, Nintendo registered their trademark over the name "Wii" in 2006 and Wii Smile only started up in 2007. Epic fail.
In a final twist, Nintendo is adamant that it's taking action not only because the name is the same, but because its "Wii" trademark also applies to dentistry.
Could the Big N be planning a dentist simulator for the Wii? Stranger things have happened...
