Apple doesn't own iCloud name

When Apple choose iPhone name for their devices they had an agreement with Cisco that owns the name iPhone, "Although Apple aggressively protects its trademark rights, Apple has a long and well known history of knowingly and willfully treading on the trademark rights of others - a history which began as early as the 1970s when Apple was first sued for trademark infringement by the Beatles record label, Apple Corp."

After Apple announced iCloud another company showed up with same name ( iCloud ), and now they are suing Apple and demanding that Apple removes iCloud name from all of their products. I asked my self " why didn't this company say something when Apple first started using iCloud name ? ".
What do you think in this problem ?
