Not so sure honestly, because the real equation would be more like "90% chances that the smaller company won't challenge it, 10% that it will even reach a verdict".

After all with the current system if it goes to court Apple/Twitter will probably have to pay a few millions for their own legal fees. Having them reimburse the other party if it goes all the way and they lose will make it even more expensive, but I don't know if it'll be enough to really change their mentality.
