Because the USP(T)O doesn't bother insisting on there being "no prior art"..before accepting patent applications and even awarding patents..
So the Corps with the biggest lawyers available file..
And if they do fall foul of "prior art" or are found to be infringing someone else's previously registered patents..they don't care..unless the other party has big lawyers and lots of money too..if not..they'll just wear them down with years of litigation..
USP(T)O..should be put down..for incompetence..or hung for aiding horse thievery and fraud..
