I wonder how strongly AT&T's new patent would stand up against prior art...
Frank
they probably have prior art also, What seems to happen is that these big telecoms comapnies hold many patents, however not knowing a use for them they get put in a cupboard and forgotten about...sometimes they leave the patents to long and they become unenforcable, ATT prob have prior art and the new patent will prob just be to legitimise the prior art and extend the patent.
Until someone reminds them about the patents lol
A year or so ago a big telecom tried to call on the patent for Hyperlinks that they held, unfortunately for them and fortunately for us they had left it to long and missed the boat on it.
