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 https://ptab.uspto.gov/#/login.
The PTAB's IPR ruling marks the third time that the U.S. Patent Office has denied Luminara's efforts to attack Liown patents using the patents Luminara licenses from Disney. When Liown's '137 patent was still just an application at the USPTO, Luminara submitted arguments that Disney's patents and other references invalidated Liown's application, but the USPTO examiner granted Liown the '137 patent after considering Luminara's submission. Luminara made similar arguments when Liown's '986 patent was still just an application at the USPTO, but the USPTO examiner also granted Liown the '986 patent.
