[Sudarshan]

I would prefer a world without software patents. If that is not possible, * At least the courts should charge exponentially high prices for each extra claim you want to make beyond a limit. * All publicly listed companies will have a cap on total number of patents they can apply for (probably proportional to R&D spending) after which the price increases exponentially. * Any person or institution found patent trolling should find further litigation exponentially expensive. All these and more measures won't solve the problem... but at least increases the threshold for trolling behaviour...
