Re: Cause for concern
I agree that this looks to be an increasingly bitter dispute that could prove to be an existential threat to either company (and possibly take others in collateral damage too).
I also agree that Qualcomm's unproven allegations seem preposterous, which is why I suggested that their veracity needed to investigated.
There seems to be a lot of disparaging of Qualcomm, and of Qualcomm's lawyers in the comments here. Surely though, it would be ridiculous to have made this rebuttal if there were not some truth in it. It would be tantamount to treating the judiciary with contempt.
I will be interested to hear Arm's complete denial. But I'd suggest, if they couldn't produce an unequivocal denial straight away, then Qualcomm does have a point.
