Disclosures that do no more than recite functions cannot
meet the "means-plus-function" requirements of §112
¶ 6.
Robert Bosch, LLC v. Snap-on, Inc. & Drew Tech., Inc.,
No. 2014-1040, (Fed. Cir. Oct. 14, 2014) (Prost, CJ.). Click Here for a copy of the opinion.
Bosch sued Snap-On and Drew Technologies for infringing US patent
no. 6,782,313. The district court held that the claim language
"by means of the program recognition device" (likewise
"program loading device") is indefinite under 35 U.S.C.
§112 ¶ 6 ("means plus function" claims), for
failing to disclose corresponding structure. Bosch appealed.
The Federal Circuit disagreed that "by means of"
automatically triggered a "means plus function" analysis.
However, it concluded that the district court's error was
harmless and affirmed that "program recognition device"
and "program loading device" nevertheless invoked
§112 ¶ 6 for other reasons.
