I should state at this point that these are personal opinions, not those of my employer.
While the first reaction when a potential competitor folds is to celebrate, that reaction is both immature and short-sighted. Not only is it a sad state of affairs that one company can destroy another using just the costs of the patent infringement process (regardless of whether the patent is valid or the infringment is demonstrable), but since competition is the fire that drives progress and innovation; seeing competition fold for any reason other than poor products is always disappointing.
