The Rosco & DMG Lumiere licensing agreement follows the settlement and licensing agreement agreed with ARRI ® earlier this year (see rotolight.com/arri): “ARRI® has agreed to a settlement with Rotolight, relating to Rotolight’s cinematic special effects “CineSFX®” patent portfolio in the US, UK, and Europe. ARRI® no longer contests the validity of Rotolight’s patents and has withdrawn its Inter Partes Review in the US accordingly.”

Rotolight also successfully defended two landmark IPR cases relating to the same patents (IPR2022-00262 and IPR2022-00261) in the USA brought against it by Vitec Production Solutions Inc. The Patent Trial and Appeal Board (PTAB) found in Rotolights favour (see IPR1 and IPR2) , denied the institution of their InterPartes patent review (IPR) and re-confirmed the validity of the granted Rotolight CineSFX® patents:

“we determine that the Petitioner (Vitec Production Solutions) does not demonstrate a reasonable likelihood that it would prevail with respect to at least one of the claims challenged in the Petition. Accordingly we deny the Petition and do not institute an inter pares review of the ‘258 patent” (p.27)

Following the PTAB’s decision and in lieu of a licensing agreement, Rotolight filed a District court patent infringement action against Videndum Productions Inc, in Delaware (1:2022cv00928) in July 2022. In April 2023, in lieu of a licensing agreement, Rotolight filed a District Court patent infringement action in Delaware against Chauvet & Sons LLC, who acquired Kino Flo, Inc® in 2021 (1:23-cv-00364-UNA)
