This is interesting. Upon the first portion of your article being read I thought "no, he should not be allowed to patent numbers. Only things that men and women discover or create should be patented." Then at the end I realized, someone has to discover algorythms for example- but math isn't something that was created by human minds. Perhaps the words we use for it are, but I'm of the opinion that though it would not be expressed without sentience the principles exist in the natural world, i.e. they are already there. Ergo for anyone to patent mathematical concepts such as numbers, algorithmic, etc. is tantamount to someone patenting a fruit they discovered. Though, I do believe due credit should be shared, such as how we document who discoveries new species or naming theories after people.
I'm all for giving credit where credit is due, we are entitled to the fruits of our work and recognition for our work. However, though we can expect recognition for discovering something no one had before, we cannot claim ownership over something we did not create.
