Entirely reasonable? “Black box” claim interpretation by split Federal Circuit panel leaves us in the dark

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 (non-precedential)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.
