If he didn't take a patent on it, then there's nothing stopping IBM from using the same techniques. The problem arises when IBM patents it as if they were the first to invent the technique, then restrict everyone (including the OP) from using the OP's invention. If IBM just used it without patenting, no problem. Of course, it's entirely possible that IBM's invention is slightly different from the OP's - patent claims are rather hard to read for a layman after all.
