Therefore by logical extension of this ruling, they have at minimum given Sky free trademarks on 82 additional words. Well, not quite. From the article: "The case was not a legal challenge to Skype's use of the mark, it was only against the registration," [a Microsoft spokeswoman] told BBC News. "We're confident that no confusion exists between these brands and services and will appeal. This decision does not require us to alter product names in any way." The court hasn't said that Sky owns the Skype trademark -- only that Microsoft cannot have the additional benefits provided by registration (which AFAIK are primarily a presumption of validity and larger damages if infringed). That said, I'm inclined to agree with you that "Sky" and "Skype" are clearly different words, despite one being a prefix of the other.
