DivX sued Netflix in 2019 alleging infringement of the '588 patent. The case was stayed for about 3.5 years pending IPRs and appeals; after trial in March 2026, the final judgment found Netflix did not infringe several other DivX patents and held others invalid, and the '588 patent did not appear in the trial verdict/final judgment.
Filed alongside the Netflix case and dismissed Aug. 25, 2022. Whether the '588 patent was among the patents asserted is not confirmed in the narrative.
DivX sued Amazon.com on Oct. 24, 2022, asserting five DivX patents relating to adaptive bitrate streaming and DRM against Amazon Prime Video and Fire/Echo Show devices. The case was stayed on Dec. 7, 2022, pending final determination of the ITC investigation; Google Patents' '588 family-litigation listing associates this case with the '588 patent.
DivX sued VIZIO on Oct. 24, 2022, asserting four patents in the same calendar round as the Amazon suit and ITC complaint. Google Patents' '588 family-litigation listing associates this case with the '588 patent; the full asserted-patent list is not confirmed.
Netflix petitioned for inter partes review of all claims 1-24 of the '588 patent in February 2020, asserting obviousness over Chen, Lindahl, and Hurst. The Board instituted in August 2020; after multiple Federal Circuit appeals, the matter was remanded to the PTAB following the Feb. 13, 2026 Federal Circuit decision in No. 24-1541.
Listed in Google Patents' '588 family-litigation data as a Federal Circuit appeal, but the narrative could not confirm the underlying matter, party posture, or originating tribunal.
