The patent system has been a sick joke for quite a while. You can patent anything these days, uploading files, the curve on the corners of a phone, ANYTHING. Consequently, you almost cannot make anything without running into issues with someones patents. Of course, patenting something is worthless if you do not have the money to go to court over it. On the flip side, you cannot make anything that might be remotely successful without having the money to defend you product from patent lawsuits. There are about 8 million US patents currently, who can afford to research all those patents to make sure they are not violating any on them (other than big corporations), and that is just in the US.
