there is more cross-talk between the companies than I would guess (through hiring former employees, reading patents, reverse engineering, etc.)
There is lots of cross-talk. Note also that Intel and AMD buy tools from other companies- and so if Cymer is making the lasers that both use for patterning, then neither of them has a laser advantage.
