A District Court application of Therasense
| February 28, 2013
Caron and Spellbinders Paper Arts Company, LLC vs. QuicKutz, Inc.
United States District Court for the District Of Arizona
November 13, 2012, Decided
SUMMARY
In Therasense, Inc. v. Becton, Dickinson & Company, 649 F.3d 1276 (Fed. Cir. 2011) the CAFC ruled that District Courts must find intent and materiality separately, i.e., weighing the evidence of intent to deceive independently from analysis of materiality.
Here, in one of the few cases since Therasense, a District Court applies separate analyses for each of intent and materiality. In addition, the District Court applied the exception to the but-for materiality requirement in cases of affirmative egregious misconduct.
Knowingly not naming the inventors was held to be inequitable conduct.
Declarations by persons not skilled in the art were held to be inequitable conduct.
Declarations that did not disclose financial relationships with the inventors were held to be inequitable conduct.
A Declaration where the Declarant, when he made the declaration, did not know whether the statements in the declaration were true or not was held to be inequitable conduct.

Entirely reasonable? “Black box” claim interpretation by split Federal Circuit panel leaves us in the dark
| February 13, 2013
Harris Corp. v. Fed Ex Corp. (non-precedential)
January 17, 2013
Panel: Lourie, Clevenger, and Wallach. Opinion by Clevenger. Dissent by Wallach
Summary:
Over a dissent, the Federal Circuit panel makes a strict interpretation of “antecedent basis,” which results in a reversal of the District Court’s claim interpretation, and a remand to re-evaluate the infringement issue.
Harris’s patents cover methods and systems for using spread spectrum radio signals to send flight data from a plane’s “black box” to an airport receiver at the end of the flight. The invention includes steps of generating, accumulating and storing flight data in the plane during the flight, followed by a step of “transmitting the accumulated, stored generated aircraft data” once at the airport.
At the District Court, a jury found that Fed Ex willfully infringed Harris’s patents by using a “design-around” system that transmits all flight data except an optional 5-minute segment.
On appeal, the Federal Circuit panel majority holds that Harris patent claims are limited to the transmission of “all data generated during the flight,” not just any data subset representative of the flight. The panel’s view is that the narrower interpretation is “entirely reasonable” since the transmitting step refers to the generating step.
In contrast, the dissent sees the claim language as open, so that it would be “counterintuitive” to require that all the generated data must be transmitted.

Board Should Consider Appellee’s Grounds For Affirming Rejection Presented To Examiner During Reexamination, Even If Grounds Had Not Been Raised On Appeal

Rexnord Industries v. Kappos
January 23, 2013
Panel: Newman, Lourie, Prost. Opinion by Newman.
Summary:
In 2003 Habasit filed an infringement suit against Rexnord in the United States District Court for the District of Delaware for infringement of its U.S. Patent No. 6,523,680 (the ’680 patent). Rexnord then requested inter partes reexamination of the ’680 patent, and the district court stayed the infringement suit pending completion of reexamination.
On reexamination, the examiner held all of the claims in the ’680 patent unpatentable for anticipation and obviousness. Habasit appealed the examiner’s decision to the United States Patent and Trademark Office (PTO) Board of Patent Appeals and Interferences (Board). On appeal, the Board reversed the examiner’s decision and held the claims patentable.
Rexnord appealed to the CAFC. The CAFC affirmed that the claims are not anticipated, and reversed the Board’s determination that the claimed invention is not obvious in view of certain prior art.
