Vivint has filed a pair of complaints (8:22-cv-00033, 8:22-cv-00034) in the Central District of California against SkyBell subsidiary SB IP Holdings LLC, seeking declaratory judgments of invalidity, noninfringement, and unenforceability of 13 patents broadly directed to communication systems located near a door or “entrance”. SB IP has filed two affirmative infringement cases against Vivint’s parent Vivint Smart Home to date, both in the Eastern District of Texas, with Vivint Smart Home accused of infringing the same patents through the provision of various smart home products (e.g., cameras, doorbells, and electronic locks) in each. Meanwhile, SB IP has appealed (22-1354) the dismissal of its December 2020 International Trade Commission (ITC) action, which was terminated in September 2021 after Administrative Law Judge (ALJ) Clark S. Cheney granted a motion for summary determination of invalidity of all seven patents asserted.

Recent setbacks in an International Trade Commission (ITC) investigation have not deterred SkyBell subsidiary SB IP Holdings LLC from continuing its litigation campaign over patents held by Eyetalk365, LLC. SB IP Holdings has sued Vivint Smart Home (4:21-cv-00912) in a second Eastern District of Texas complaint, targeting Vivint’s provision of smart home products (including cameras, doorbells, and electronic locks) with six more “entryway management” patents.

In the second half of March 2016, RPX saw twelve patent transfers to known NPEs recorded with the USPTO. Several of those transactions involved patents that have already been asserted in litigation against operating companies.
