Those patents disclose algorithms. Basically, applied math. Which should have never, ever been allowed as claims in a patent since they are antithetical to the compromise between the inventor's and society's benefit the patent system was designed to facilitate. So, yes, they are pretty much what one would call "software patents".
Whether or not they describe revolutionary ideas, and whether or not they required creative thought to invent is completely beside the point. Patenting algorithms runs against the very worldview that built the research scaffolding which allowed you to come up with these ideas (the old adage about standing on the shoulders of giants--and now imagine a world where those shoulders could only be visited if you paid the piper.) Math isn't invented, it's discovered.
That being said, under no circumstances would I recommend a client to hire you if I caught wind that you owned patents applicable to the field in which you would be working. That simply screams "conflict of interest", "subsequent lawsuit", and "humongous liability."
