If you have been following the ongoing series of court debates between LG and Whirlpool, you’ll be aware of the back and forth battles regarding steam dryers and refrigerator patents.

The United States District Court in Chicago this week entered a final judgment in favor of Whirlpool in a case filed by LG Electronics involving Whirlpool’s steam dryer advertising. The court had previously ruled that “Whirlpool has established that its dryers do, in fact, use steam,” and that “LG did not introduce expert testimony or credible evidence of even a single Whirlpool customer, retailer, or trade representative who expressed confusion.”

“We’re very pleased with the Court’s decision,” said Marc Bitzer, president, Whirlpool North America Region. This victory means consumers will continue to have a choice in purchasing their steam laundry appliances.”

While this seems to settle the steam dryer case, the refrigerator patent battles continue. LG originally sued to have Whirlpool fridge patents invalidated; Whirlpool countersued. In March 2010, a jury trial found mostly in favor of Whirlpool and awarded Whirlpool $1,786,925. On July 1, 2011, the court granted a new trial and set a trial date of Sept. 28, 2011.

Whirlpool is seeking a judgment that better validates its patent claims; LG seeks to have the claims of patent violation invalidated and eliminate its liability. Stay tuned…
