Some of these mines are impossible to clear. Every software patent is harmful, and every software patent unjustly restricts how you use your computer, but not every software patent is legally invalid according to the patent system's criteria. The software patents we can overturn are those that result from &ldquo;mistakes&rdquo;, where the patent system's rules were not properly carried out. There is nothing we can do when the only relevant mistake was the policy of allowing software patents.
