KYOCERA SENCO INDUS. TOOLS INC. v. ITC [OPINION] (2020-1046, 2020-2050, 01/21/2022) (MOORE, DYK, and CUNNINGHAM)
Moore, C.J. The Court vacated and remanded an ITC decision finding infringement of a patent directed to “fastener driving tools,” such as “portable tools that drive staples [and] nails.” The court addressed multiple issues on appeal and cross appeal. First, the court held that the ITC ALJ abused his discretion by allowing Kyocera’s expert to testify on issues analyzed through the lens of one of ordinary skill in the art because the expert did not meet the definition of one of ordinary skill in the art. Second, the Court affirmed the ALJ’s construction of “driven position” based on a definition provided in the patent specification. Third, the Court held that the ALJ erred by not interpreting “lifter member” as a means-plus-function term under 35 U.S.C. § 112 ¶ 6. The Court explained: “The ‘lifter member’ limitation does not use the word means, so there is a presumption that § 112 ¶ 6 does not apply. But because that claim term does not recite sufficiently definite structure, that presumption has been overcome… It is a non-structural generic placeholder (member) modified by functional language (lifter).” Fourth, the Court construed the “safety contact element” and “fastener driving mechanism” as “separate components” of the claims. Fifth, the Court held that the ALJ’s invalidity analysis with regard to the “main storage chamber” element of the claims was supported by substantial evidence.
