Packalen and Bhattacharya indexed every one-word, two-word, and three-word 
phrase that appeared in more than 4 million patent texts in the last 175 
years. To focus their search on truly new concepts, they recorded the year 
those phrases first appeared in a patent. Finally, they ranked each 
concept's popularity based on how many times it reappeared in later 
patents. Essentially, they trawled the billion-word literature of patents 
to document the birth-year and the lifespan of American concepts, from 
"plastic" to "world wide web" and "instant messaging."

Interesting study. I think a similar study into Recmgmt-l posts would be 
interesting - show the topics we talked about most at the different points 
in time. Maybe a paper for one our MLIS students? Of course, there will 
need to be some empirical analysis, as in, "why the spike in "chili 
recipe" in 2002?"
