CAFC Rejects Claim Construction on Plain Meaning when Context Leads to a Different Interpretation

The district court erred by relying entirely on the plain meaning of the claim where context-based interpretations were necessary. The Court held that the plural terms “intervals” and “remotes” in isolation could mean what must occur during each interval and what was applicable to all the remotes, but there was no requirement indicated in the remaining claim language or specification that at least one remote transmit and receive frames during at least one interval. The Court held that this evidence, together with other language in claim 21, and teachings in the specification, showed that each cycle in the claims must have intervals in which remotes were allowed to transmit.

CAFC Reverses Claim Construction on Operability Requirements of the Invention

The Federal Circuit reversed the district court’s claim construction, and held that the claim language does not require that the start and duration of remote-transmission intervals be communicated prior to the beginning of the cycle. St. Jude had not explained why, in accordance with the specification, it was not sufficient that a remote know roughly when to expect an upcoming cycle to begin, rather than its exact starting time, and why such interval information could not be communicated during a cycle. The Court postulated that a remote unit could power up its communications equipment for the entirety of a first cycle, receive interval information whenever it was transmitted, then only power up that equipment during its assigned interval for subsequent cycles.
