Power-One, Inc. v. Artesyn Techs., Inc. (Fed. Cir. 2010)

代表的なクレーム:
1. A power control system comprising:
a plurality of point-of-load (POL) regulators;
at least one serial data bus operatively connecting said plurality of POL regulators; and
a system controller connected to said at least one serial data bus and adapted to send and receive digital data to and from said plurality of POL regulators;
wherein, programming, control and monitoring information is carried on said at least one serial data bus between said system controller and said plurality of POL regulators.

United States Patent 7000125

分析:
連邦地裁は、クレームに記載の用語“POL regulator”を次のように解釈していた。

“dc/dc switching voltage regulator designed to receive power from a voltage bus on a printed circuit board and adapted to power a portion of the devices on the board and to be placed near the one or more devices being powered as part of a distributed board-level power system”

Federal Circuitは、この解釈は内的証拠(intrinsic record)によってサポートされていると判断した。すなわち、“POL regulator”はよく知られた装置であり、パワーシステムにおける他の要素との関係(位置や機能)は当業者が理解するところである、とFederal Circuitは述べた。このように、当業者は“POL regulator”をどこに配置し、どのように使用すべきかを理解できるため、Federal Circuitは“POL regulator”について35 U.S.C. §112¶2に基いて不明確ではないと判断した。
