In 1977, to commemorate the 25th anniversary of the creation of section 103 as part of the 1952 recodification of the Patent Act, John Witherspoon organized a conference on section 103.  It lead to the publication of a BNA volume entitled, “Nonobviousness-The Ultimate Condition of Patentability.”

My question is this: Has there been, since that 1977 conference, any other U.S. law conference devoted entirely to patent law’s nonobviousness standard?  If you know of such a conference (e.g., from having attended it, or having seen a law review issue devoted to its proceedings), please leave a comment to this post with as much information about it as you can remember.

Thanks!
