    Re:When does a domain name exist?

    "What is an invalid domain name?"

    Terms in the claims are defined in the full specification of the patent. While "invalid domain name" appears in the abstract, it is not a term in the claim. The claim refers to a domain name that does not exist in a "master lookup table".

    There is little question what the patent means by "invalid domain name", e.g.:


    "DNS requires that the domain name be exactly correct or it may map to an unintended domain or be invalid (non-existent) and fail to map to a machine address."


    "The present invention provides a system including a domain name server that assists user's in selecting desired domains in the Internet. A domain name query is sent from a resolver process, or equivalent process, when the user (or a process on the user's computer) wishes to obtain information. If the domain name exists, the domain name server provides the corresponding machine address back to the user's computer. However, when the domain name query uses a non-existent domain name then a machine address for a computer that executes a domain recommendation engine (DRE) is provided. The domain recommendation engine assists the user (or process on the user's computer) in locating a desired domain name."

    As used in the specification, the terms "invalid" and "non-existent" would appear to be synonymous.

    If there is agreement that any domain name that exists in a master look up table falls outside the scope of this patent and...

    using the patent definition, that the definition of a domain that does not exist to be one that is not listed in a master look up table...

    then, does a domain with a wild card exist in a master look up table?
