Possible Patent Infringement regarding Variable Speed Pumps

Pentair asks for an injunction that aims to force Hayward to stop selling the EcoStar.

Pentair Pool Products, manufacturer of the IntelliFlo and the IntelliPro lines of variable speed and variable flow pumps, in association with Danfoss Drives--the makers of their variable frequency drives, filed a motion on August 31, 2011 requesting an injunction that would stop Hayward, manufacturer of the EcoStar from selling their EcoStar pump.

Pentair & Danfoss (collectively referred to as Pentair in the brief) maintains that Hayward's EcoStar is in violation of three of Pentair's patents. In a preliminary hearing, the court found probable merit in Pentair's claims regarding patent infringement. At the same time, the court failed to see that any possible infringement would result in irreparable harm to Pentair. And, furthermore, in weighing matters of public interest in the matter, the court leaned slightly towards favoring Hayward.

As matters stand now, the preliminary injunction was denied on January 23, 2010, so Hayward, for the time being, can continue to sell and show its EcoStar product, but now the case moves to trial. Stay tuned.

A brief of the preliminary hearing can be found here.
