Appeal No. 1999-0890 Application 07/575,096 recites a means for performing a specified function without the recital of structure to perform the claimed function. See 35 U.S.C. Section 112, Para. 6 (1994); Cole v. Kimberly Clark Corp., 102 F.3d 524, 531, 41 USPQ2d 1001, 1006 (Fed. Cir. 1996) ("To involve [Section 112, Para. 6], the alleged means-plus-function claim element must not recite a definite structure which performs the described function.") The proper construction of a means-plus-function claim limitation requires interpreting the limitation in light of the corresponding structure, material, or acts described in the written description, and equivalents thereof, to the extent that the written description provides such disclosure. See In re Donaldson Co., 16 F.3d 1189, 1193, 29 USPQ2d 1845, 1848 (Fed. Cir. 1994) (in banc). Structure disclosed in the written description is "corresponding" to the claimed means under Section 112, Para. 6 if the structure is linked by the written description or the prosecution history to the function recited in the claim. See B. Braun Medical, Inc. v. Abbott Labs., 124 F.3d 1419, 1424, 43 USPQ2d 1896, 1990 (Fed. Cir. 1997); see also Chiuminatta Concrete Concepts v. Cardinal Indus., Inc., 145 F.3d 1303, 1308, 46 USPQ2d 1752, 1755-56 (Fed. Cir. 1998). 12Page: Previous 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 NextLast modified: November 3, 2007
