There aren't any in the US Patents, but someone did plot graphs themselves. I do not know the method they used but here is the archived site:

Chloe, are you working in CTU London office?
I've been searching the site for 24 hours x3. The site was named "kiiboodo no heya", (room of keyboard ).  the site owner measured pressing force of various keyboards by himself.  I don't know his measuring method though.  It's a shame that i didn't download whole data before the site vanished away.

I am working undercover. ;)

Most of the site seems to be archived:
http://web.archive.org/web/*/http://www5f.biglobe.ne.jp/~silencium/keyboard/index.html
I think there is an explanation of how the graphs were made on the main page. With small enough weights, digital scales and a magnifying glass it would be possible to plot a graph. You can also buy hand-held force gauges although they are quite expensive.

I am trying to find Alps Force Graphs.  I accidentally found them yesterday but I closed the window and now I need to find them today.  Google sent me to this thread.
