Toward the end of an article about how computers are getting too good at text recognition is an odd bit: "H-P no longer owns the patent, said Brigida Bergkamp, a spokeswoman for the technology giant.

Isn’t that made harder if they can’t find out who you are? Isn’t who holds a patent public information?
