Nortek Air Solutions Continues To Protect its Patented Fanwall Technology

Aug 22 2016

Eden Prairie, MN (August 22, 2016) — Nortek Air Solutions (a subsidiary of Nortek, Nasdaq: NTK), the leader in custom heating, ventilation, and air conditioning equipment brands in North America, today announced that it is considering all its legal options, in response to the jury’s verdict in its patent infringement lawsuit against Energy Labs, Inc., DMG Corporation and DMG North.

On August 10th, the jury in the United States District Court for the Northern District of California failed to find infringement of seven claims in six Nortek patents.  The jury upheld the validity of three of the seven claims, but found the other four to be invalid.  The patents in suit are U.S. Patent Nos. 7,922,442; 8,398,365; 8,414,251; 8,562,283; 8,694,175; 8,734,086.

As a result of its innovative design, the ECE Building uses 50% less energy than the minimum building energy efficiency standards established in ASHRAE Standard 90-2007 – what the architectural and engineering designers on the project, SmithGroupJJR, called “an exceptional achievement considering the energy-intensive nature of a laboratory building containing an instructional cleanroom.”

“We disagree with the verdict,” said Mark DeVincent, President of Nortek Air Solutions. “Nortek Air Solutions has invested significantly in creating and bringing to the market our industry leading FANWALL TECHNOLOGY®.  We have protected this technology with a large patent portfolio, with 16 issued patents to date in the US and 2 pending US patent applications.” said DeVincent.  “While we consider this verdict a setback, we will continue to protect and expand our valuable assets. We will also continue our commitment to invest in innovative solutions that provide outstanding benefits to our customers.”
