Watch this video on Patenting. I knew Nothing about Patent Creating, Laws, and controversies prior to watching this half hour video made ten years ago. Now, I know a little bit and am amazed at how the US Legal System, Lawyers, Legislators, Judges have decided that Mathematical Algorithms are now patentable processes, which software creators both rejoice over; and abhor. VERY educational if you have a curious mind, such as myself, that loves to learn a little about a lot in the limited time we have during our life.
