Big companies with big pockets are very nervous about being too closely associated with Linux because of this problem. Imagine that IBM, for example, starts shipping IBM Linux. Somewhere in the code there is something that infringes on a patent. Given that it is IBM Linux, people can make the case that IBM should have known and should have fixed it and since they didn't, they get sued. Notice that IBM doesn't ship their own version of Linux, they ship / support Red Hat or Suse (maybe others, doesn't matter). So if they ever get hassled, they'll vector the problem to those little guys and the issue will likely get dropped because the little guys have no money to speak of. Maybe this is all good, I dunno, but be aware that the patents have long arms and effects. -- --- Larry McVoy lm at bitmover.com http://www.bitmover.com/lm - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
