Representing Whirlpool, a leading manufacturer and marketer of home appliances, Morrison & Foerster won a federal jury verdict on March 10th, 2017, in the Eastern District of Texas following a weeklong trial. After deliberating for three hours, the jury awarded Whirlpool $7.6 million in damages Friday, finding that TST Water, a manufacturer of water filtration products, had willfully infringed on a patent for refrigerator water filters.

The jury decided that Whirlpool’s patent was valid and that TST’s Whirlpool refrigerator-compatible water filters, sold under the brand name WaterSentinel, infringed on all seven claims at issue in the matter. The complaint that Morrison & Foerster filed on behalf of Whirlpool 18 months ago alleged that the WaterSentinel WSW-5 and FMW-5 filters intentionally copied Whirlpool’s Filter 3 product design, and that TST’s website said its products are “guaranteed to fit” Whirlpool’s refrigerator filter assemblies.

Morrison & Foerster tried the case alongside attorneys from Ward, Hill & Smith and Gilliam & Smith. The Morrison & Foerster team representing Whirlpool included partners Richard Hung, Michael Jacobs, Bita Rahebi, and associates Barbara Barath, Jamie Kendall, Rachel Dolphin, and Chris Wiener.
