I haven’t been able to talk about it before now, but thanks to the USPTO it appears to be public knowledge that the Exbiblio patent portfolio was recently acquired by Google. (The company basically closed down after Martin King passed away last year.)
As is so often the case with my exploits, by the time they actually make any money I no longer have any financial stake in them! But it’s encouraging to think that the weeks and months that I and others put into writing those patents did at least produce something that others found valuable enough to pay reasonably substantial sums for them.
Congrats to all concerned!
