US Trade Panel Wades Into Caterpillar-Wirtgen Patent Spat

摘要

A patent fight is heating up between construction-equipment makers Caterpillar Inc. and Wirtgen Group Holding GmbH, Windhagen, Germany, over milling and paving machines. The latest action is the U.S. International Trade Commission's Nov. 22 announcement that it will launch a probe in response to a Caterpillar filing against Wirtgen. In its Oct. 26 complaint, Caterpillar alleged that Wirtgen Group Holding and three of its subsidiaries sold road-construction equipment in the U.S. that infringe on Caterpillar patents. The filing was posted by the independent ITC 337 Law Blog.
