the point is,many millions there dont know that a patent exist for his idea.
I also condemns the purposeful copying of patented ideas if any.but...many
FOSS developers and small companies
innovates something later to know that there is a patent killing all this invention.
infact the weakest is FOSS..where any software's code is open and open ideas,open standards also,a patent troll company can handpick ideas and file a patent.then sue the original developer(s).
