Sony Ericsson sues Clearwire over brand logo

S­ony Ericsson has filed a lawsuit against Clearwire (NASDAQ:CLWR) claiming that the WiMAX operator's logo is too similar to its own brand logo.

Sony Ericsson claims that Clearwire's "infringing sphere with swirl logos" is confusingly similar to its own swirl registered trademarks. Sony Ericsson said that Clearwire had originally agreed to stop using the logo with a reverse image after it complained in late 2009. But now the handset maker says Clearwire's current logo is still too close to its own design.

The trigger may have been Clearwire's decision to sell its own branded WiMAX phones with the Clearwire logo, although that plan has now been delayed.
