That really is a good sign. The patent should stand on it's own if at all possible. I didn't understand why tmob was so intent on deposing him at this juncture anyway. The expert is considered extrinsic, just as a dictionary would be. The patent terms and meanings should trump any other source, if possible. So if the judge is relying on the patent, he will be able to determine the meaning of the terms within the context of how they were written. I don't find this an exceedingly hard patent to understand, let's hope the judge sees it that way also.
Tmob's attempt was to quarantine the terms, use extrinsic evidence to support their argument, so they could redefine the patent terms, thus making the patent invalid or at least not infringed upon.
