I think you have precisely described the problem with patents. I have
jpegs on computer book CD's from 1995. So they were already popular
back then. The patent link in the article says it is from 1987, let's
see going on 17 years and they are just in the last couple of years
getting around to filing lawsuits?  How about 9+ years ago? These are
lawyers digging for gold and nothing else.  If the judge had any
brains he would through it out in an instance.
