As a patent attorney, I am providing an update on known litigation involving US Patent 8,839,293. As of April 26, 2026, my search for this specific patent number in publicly available litigation databases did not yield any direct results.
Therefore, no specific litigation cases listing US Patent 8,839,293 as directly involved (e.g., as the patent asserted in an infringement suit) were found.
It is important to reiterate that the absence of results in a general web search for litigation does not definitively confirm a complete lack of litigation. Comprehensive litigation history often requires direct access to private legal databases, PACER, or a more detailed investigation of court records. The previous analysis noted that the original assignee, Personalized Media Communications LLC, has been involved in litigation concerning other patents in its portfolio. However, this does not automatically extend to patent US8839293B1 without specific evidence.
