If memory serves, Kennedy's arguments in the SCOTUS decision in the Bilski case are based in part on apparent congressional intent. I don't have concrete citations to actual congressional activity; this impression is seeing it alluded to or asserted in decisions such as In re. Bilski. I'm making the assumption that the justices are not totally fabricating, although they may be misinterpreting.
