Absent Contrary Evidence, Claim Terms Appearing In Different Claims Presumptively Carry The Same Meaning


In PODS, Inc. v. Porta Stor, Inc. (No. 06-1504, April 27, 2007) a Federal Circuit panel reverses a district court’s judgment of infringement. The asserted patent includes both apparatus claims and method claims directed to “lifting a storage container from the ground onto a transport vehicle or vice versa.” With respect to the asserted apparatus claims, the parties agreed that the recited “carrier frame” required a four-sided frame. There was, however, no such agreement between the parties with respect to the “carrier frame” recited in the asserted method claims. Unlike the method claims, the asserted apparatus claims included a fairly detailed structural description of the recited carrier frame. The district court ruled that the omission in the method claims of the same structural description found in the apparatus claims “presumably carries consequences” that “the carrier frame described in [the method claims] is less precise and limited.”

Citing Fin Control Sys. Pty., Ltd. v. OAM, Inc., 265 F.3d 1311 (Fed. Cir. 2001), the Federal Circuit finds that the district court erred by failing to apply the “presumption that the same terms appearing in different portions of the claims should be given the same meaning unless it is clear from the specification and prosecution history that the terms have different meanings at different portions of the claims.” Id. at 1318. No evidence is found, says the panel, in the specification or prosecution history that the term “carrier frame” in the method claims has any meaning other than the uncontested meaning ascribed to it in the apparatus claims.
