Not me... and I know...
O.K. Sorry and maybe the article was corrected after it was posted here. I'm usually skeptical regarding claims of patent trolls - OMG Microsoft has patented sudo! (They have not). This one doesn't pass. Thumb nails have been used for a very long time and long before 2001. XV probably didn't have a very large user base, but it was sure out there.
It's sad too. XV was a wonderful graphics viewer. Better than any I've seen since.
