Not the same story but related: Microsoft had to rebrand his online storage SkyDrive to OneDrive once because the television broadcaster "Sky" won a trademark lawsuit in UK.

Can anyone tell me how this is possible? Why am I not allowed to use the word "sky" in any product name completely unrelated to TV?

Sky is also an internet service provider. Not as far removed as TV really, and SkyDrive is hardly unrelated to internet service.

I'd say it doesn't seem to be a problem for Box and Dropbox, but it probably is; the two companies are just too similar.
