Eaton Corporation fired first with this press release on Nov. 21 following the court decision:
The U.S. District Court in Wilmington, Delaware in late November granted a permanent injunction against Parker Hannifin Corporation regarding an Eaton Corporation patent for an innovative Snap-to-Connect (STC) technology used in high-pressure hydraulic applications.
The Nov. 18 ruling by U.S. District Judge Sue Robinson prohibits Parker from manufacturing, marketing or selling its Generation II and Generation III Perma Push connectors and any colorable variations of them.
Additionally, the court confirmed that two other related Eaton patents are also valid and enforceable. Eaton filed the patent infringement suit against Parker on Aug. 15, 2000. Eaton's patented Snap-to-Connect technology has numerous applications for mobile and industrial equipment.
"We are very pleased that the court validated Eaton's patents and that Parker's Perma Push product will no longer be able to infringe upon our patented technology," said Jeff Finch, director of marketing for Eaton hydraulics. "Eaton remains committed to providing our customers and industry with game-changing technologies and to protecting the investments we make in the design, development and deployment of these technologies."
Parker responded to Eaton's release the same day with the following:
