Due to the extensive number of district court cases listed for California Northern District, Delaware, Florida Middle, Texas Eastern, and Texas Western District Courts, and the CAFC cases, a full, detailed listing for each case with specific plaintiff, defendant, filing date, and current status would require individual searches for each case number on platforms like PACER or Unified Patents' portal. The provided snippets offer the case numbers and jurisdictions but lack the detailed party and status information for many of these individual cases.

For instance, the Google Patents page lists 26 cases in the California Northern District Court, 12 in Delaware District Court, 1 in Florida Middle, 1 in Texas Eastern, and 5 in Texas Western. Providing full details for each is beyond the scope of the current search results without more targeted individual queries per case to a live legal database.
