Well, it appears there already is an existing iCloud out there–iCloud Communications. They’re not happy over the use of iCloud and in turn are suing Apple, according to TNW.
The goods and services with which Apple intends to use the “iCloud†mark are identical to or closely related to the goods and services that have been offered by iCloud Communications under the iCloud Marks since its formation in 2005.  However, due to the worldwide media coverage given to and generated by Apple’s announcement of its “iCloud†services and the ensuing saturation advertising campaign pursued by Apple, the media and the general public have quickly come to associate the mark “iCloud†with Apple, rather than iCloud Communications.
Essentially the company wants Apple to cease the use of the name iCloud entirely. iCloud Communications specializes in VoIP solutions for small to medium-sized businesses. It’ll be interesting how Apple will respond to this one.
