Inventor-controlled Core Optical Technologies, LLC has revived its sole litigation campaign, suing Juniper Networks (8:19-cv-02189) and Nokia (8:19-cv-02190) in separate Central District of California complaints. The cases were filed roughly two months after a settlement between Core Optical and Infinera led to the dismissal of the last active case in the campaign. The same patent, generally related to separating multiple optical signals (“waveforms”) on the same frequency using a cross-polarization interface canceler technique, is asserted, with infringement allegations targeting the defendants’ products containing dual polarization coherent optical receivers.
