Some people say that programmers should NOT look at such patents, for
reasons of "willful infringement". So anyone considering looking at
patents should inform themselves on that topic. I personally will not
look at them, even being outside the USA where the reasoning probably
doesn't hold.

Some other people say that algoritms should not be patented at all,
being pure mathematics and all that.
