I find it interesting that here, when a university is doing the patent-suing, HN errs on the defensive side:<p>"Accusing Carnegie Mellon of patent trolling is probably not the most effective way to advocate for patent reform."<p>"Universities have been among the biggest producers of patents for 50+ years now."<p>"The internet needs more details so we can make an uninformed opinion and collectively decide to be impotently pissed off at the university or not."<p>However, when a large commercial entity is suing (e.x. Apple v. Samsung [1]), HN bashes the patent system:<p>"these cases set a chilling precedent for the platform that looks likely to dominate the computing industry for at least the next decade."<p>"It will hurt innovation because every damn thing is going to have to go through a committee of lawyers before being approved, and it will hurt innovation because the idea that innovation always involves making something brand-new and from whole cloth is fucking retarded."<p>"Apple's successful use of the broken patent system sends exactly the wrong signal."<p>Are these entities (Apple and CMU) really all that different? Both spend a lot on R&D, and both want to protect their property. In a sense, there are better reasons to support Apple filing patent lawsuits (forgetting about the specifics of either suit) than CMU. CMU receives a large fraction of funding from taxpayer-funded sources, and produces no real products, just IP. By contrast, Apple receives very little taxpayer money, and uses the patent system to defend its real products.<p>[1] <a href="http://news.ycombinator.com/item?id=4430101" rel="nofollow">http://news.ycombinator.com/item?id=4430101</a>
