Re: Prior art in Europe?
Our company used a gateway between telex and MHS, depending only on the phone number and a table mapping the service type and address, from the midst of the 80s to the end of the nineties, over time telex was replaced by SMS and fax, MHS by SMTP. It was done by the IT department and never patented, cause it lacks the amount of invention which was needed to get a German patent at that time. Obvious usage of prior art is a exclusion criterion to get a patent in many countries.
