Google's Nexus One has been hit by a double whammy of disappointment this week following suggestions of poor sales and the news that the application of its name to be trademarked has been turned down.

Although some believe Google isn't in it for the market share, that hasn't stopped critics panning the company's poor performance in selling the "Google phone" since its launch at the beginning of January.

According to Mobile application analytics firm Flurry, Google has sold 135,000 handsets through its online store without support, aside T-Mobile in the US, from carriers around the globe.

But that doesn't appear to be the worst of the news.

Cnet in the UK is reporting that "Google filed the Nexus One trademark on 10 December last year for use in connection to mobile phones, and despite there not being another Nexus phone on the market, the US Trademark Office has this month issued a notice of refusal".

The reason for the refusal? Someone in the US Trademark Office believes consumers would be confused with the other Nexus trademark in use in the same space (yeah, we neither).

If Google doesn't opt to respond to the refusal then it theoretically would either have to buy rights to the name or change the name of the phone altogether.

Sony Ericsson, who last year was calling its Android UI Nexus, has quietly dropped the name since the Google phone was released.
