Assuming for the moment that the three engineers did NOT as alleged, make off with thousands of documents from Motorola. Remember they are not the ones being sued. The exhibits provide no support of those allegations. Motorola has in past filed criminal charges against a female Chinese Engineer, yet in this case did not despite claiming overwhelming evidence. Is the end game to crush Hytera or extract royalties?
Look at the features being patented and tell me how DMR will work minus those features? And look and see that most appear to be simple logic decisions like scanning for a TG or time slot. The networking patents seems to be some confusing extrapolation of Iridium. The automatic volume control is a feature I have seen in some luxury GM vehicles to adjust the radio according to cabin noise. Hardly novel.
I hope Motorola has extracted purloined software code to bolster their argument because a few simple flow charts won't convince a jury. I think the strategy is one to overwhelm a jury.

I really don't have a dog in this fight. I just want to play devils advocate and I will be watching with interest. If this really is what Motorola claims, it says a lot about corporate loyalty (a rocky two way street) , economic danger of H1B Visa's and greed (of all parties).
