I couldn't disagree more with the linkage some have between companies only using patents "defensively" and/or financially rewarding employees to file patents. The two are unrelated.<p>Yahoo is dying. It has been for some time, arguably the better part of a decade. At some point all such companies end up in hands of management and/or a board who simply want to extract every last dime. Much like how some dying stars go supernova, large dying companies often explode in a conflagration of litigation. We saw it with SCO. Now it's Yahoo's turn (apparently).<p>But to argue that this is a product of acquiring patents is ridiculous. Not doing so will do nothing but hasten your demise. Software patents are ridiculous and should be declared invalid (wholesale) but until that happens, that's the system we live in.<p>If anything, the more ridiculous patent lawsuits we have, the more it hastens the onset of commonsense and (hopefully meaningful) patent reform.
