T9 is a bit different from a true predictive text entry system. T9 is more accurately described as a disambiguating text entry system. It does not predict what word will be entered next, but rather cycles through the possible words that could correspond to the keys pressed. It's much easier than true word prediction because the number of characters of the word to be "predicted" is known.

J. Carlberger published a paper titled Design and Implementation of a Probabilistic Word Prediciton Program in 1997. That should pretty much take care of the prior art argument.
