Why should "loser pays" be limited to patent trolls?<p>I understand that they're the least sympathetic players is a patent system, but a bogus patent lawsuit is a bogus patent lawsuit. I would even argue that, in many cases, a company trying throw sand in the gears of their competitors by using patents that never should have been granted is <i>worse</i> than a patent troll. At the end of the day, a patent troll just wants to extract money (and typically is happy to extract it from all players equally). A company suing its competitors, by contrast, is trying to upset the competitive balance in some market which can easily have more far-reaching implications.<p>One counterargument I've heard is that we don't need "loser pays" for practicing entities because they can be countersued with your own portfolio, so you can eventually negotiate a truce based on MAD. To me, this misses the point. MAD is a workaround for some bugs in the patent system, not an end in itself. If there's a better way to discourage trumped-up patent lawsuits, we should use it too (or even instead, depending). And MAD has significant weaknesses (doesn't protect small players vs big players, favors incumbents, etc.) that a broad "loser pays" could help.
