Apple have also hired many senior Imagination engineers and employees over the last few years. From Imagination's perspective, rather than changing to different technology, Apple are trying to reimplement Imagination's technology, with ex-Imagination engineers, without paying them. Whether Imagination are right about this or not, I don't think this is a clear cut case of patent bullying.
