Microsoft found itself on the receiving end of copyright law enforcement on Friday after a London judge ruled that its popular Skydrive service is in violation of the “Sky” trademark owned by British Sky Broadcasting Group.

Sky is the largest satellite television provider in the UK and Ireland with over 10 million subscribers. Microsoft argued that that the broadcaster’s trademark should not apply to Skydrive because consumers can easily distinguish cloud storage solutions from pay-TV packages on “grounds of descriptiveness,” but Judge Sarah Asplin would have none of that.

Asplin said although “there was no use of the Sky get up or indicia in Skydrive, it seems to me that the evidence revealed confusion amongst real people.” She also dismissed Microsoft’s attempt to make the word “free for use by all traders” offering cloud solutions on the basis that it wasn’t associated it with the technology back in 2008, the year Skydrive launched in the UK.

Microsoft plans to appeal the decision. Should the company fail to overturn the verdict, it will likely have to rename the cloud locker as it did with the Windows 8 Metro interface last year.

As important as this issue may be, trademark violation is the least of Microsoft’s concerns in the cloud arena. The software giant is facing increased competition from Dropbox and Google, which recently tripled its free storage offering from 5GB to 15GB. This capacity is shared across all Google services, including Google+, Gmail, and Google Drive.

The upgrade places Google eight gigabytes ahead of Skydrive, 10 gigabytes ahead of Apple’s iCloud service and 13 gigabytes ahead of Dropbox. SiliconAngle Assistant Editor Ryan Cox pointed out that the move gives Google a “back door entry to the enterprise,” Microsoft’s home turf.
