The search results for "US8228801B2 litigation unifiedpatents.com", "US8228801B2 litigation CAFC", and "US8228801B2 litigation PACER" did not return specific case details beyond what was already listed in the "Family has litigation" section of the Google Patents page itself. Unified Patents states that it provides "Complete data for USPTO examiners" and "Search District Court patent litigation for latest filings" but the specific search for 8228801 on Unified Patents did not yield additional details beyond what was visible on the Google Patents page. Similarly, the PACER and CAFC general information did not provide specific litigation details for US8228801B2 without directly accessing their search functions, which would require specific login and search criteria beyond the scope of this interaction.Known litigation involving US patent 8228801 is as follows:
