I believe, though could be mistaken, that this valuable list of current US e-learning patents was created by Jim Farmer at im+m.
This next comment goes in the “Scott complaining about something that is free” bin, but Jim, is there any way you could maintain this (if that is what you are doing in) in something like DabbleDB or a GoogleDoc spreadsheet? Something that automatically produces an RSS feed (and that you could give permission to others to add to, so as to not have to shoulder the burden alone).
Efforts like this that keep the community appraised are immensely valueable. And I don’t want to sound ungrateful, but much like the case with the Ed Tech conference listings I documented a while back, in this day and age we need to be looking at web-based formats and tools by default, ones that produce RSS and allow collaborative editing. There is simply too much too kepp track of to do otherwise, and it is only in spreading the load that we can hope to keep up. – SWL
