Luminara’s Request to Challenge Liown’s Flameless Candle Patents Denied by U.S. Patent Appeals Board

MINNEAPOLISJuly 11, 2016 /PRNewswire/ — Liown Electronics Co. Ltd., one of the world’s largest suppliers of light-emitting diode (LED) flameless candles and lighting, today announced that the United States Patent Office’s Patent Trial & Appeal Board (PTAB) has refused Luminara’s request to review Liown’s U.S. Patent No. 8,926,137.

“From the start of our patent disputes with Luminara, we have steadfastly maintained that Liown is the original innovator in the flameless candle industry,” said Johnny Yang, Liown CEO. “This ruling from the PTAB helps confirm that our IP is as strong as we have always maintained.”

Luminara had requested that the PTAB institute a so-called inter partes review (IPR) of Liown’s ‘137 patent.  To institute such a review, the PTAB would have needed to find that Liown’s ‘137 patent was likely invalid.  And, by refusing to institute, the PTAB showed its faith in the validity of ‘137 patent. In Luminara’s petition, it argued that the patents Luminara licenses from Disney invalidated Liown’s ‘137 patent.  But the PTAB squarely rejected those arguments. The PTAB’s decision is available online at
