The Google Patents page for US7203844B1 lists extensive litigation, specifically stating "Family has litigation" and providing numerous links to cases filed in various US District Courts. I will list these cases and extract the requested information.

Here is a list of known litigation involving US patent 7203844, with details for each case where available from the provided patent information:

Plaintiff: Torus Ventures LLC (current assignee as of 2021-10-12)

Defendant(s): Not explicitly named in the Google Patents summary for each individual case entry, but typically the defendants in patent infringement cases are the companies accused of infringing the patent.

Jurisdiction, Case Number, and Status/Outcome (as of 2026-04-26):

The Google Patents page indicates that Torus Ventures LLC is the current assignee and lists numerous cases. The individual case entries from Google Patents only provide the jurisdiction and case number, along with the source being "District Court" and the status being "litigation". Exact filing dates and specific outcomes for each listed case are not detailed in the provided Google Patents snippet. However, the sheer volume of cases listed suggests active assertion of this patent.

Here are some examples of the numerous cases listed, all in various District Courts within Texas and one in Delaware and one in New York. The provided text does not explicitly state the plaintiff or defendant for each individual case entry in the litigation section, but given Torus Ventures LLC is the current assignee and the patent is listed as having litigation, it is highly probable Torus Ventures LLC is the plaintiff in these cases.

Current Status: All of these cases are listed as "litigation" on the Google Patents page, and many have recent filing dates in 2024 and 2025 (relative to the current date of April 26, 2026). This indicates active litigation. The Google Patents page also notes "Expired - Lifetime, expires 2025-08-09" for the patent's legal status. While the patent is listed as expired, this would apply to new infringement. Cases filed before the expiration date (or for infringement occurring before the expiration date) can still proceed.

The exact filing dates and outcomes for each specific case would require access to court dockets (like PACER), which is beyond the scope of this response given the provided information.
