The Google Patents page lists "Realtime Data LLC" as the Current Assignee and Original Assignee, suggesting they are often the plaintiff in infringement cases. However, the specific plaintiffs and defendants are not uniformly provided for each case in the listed litigation section of the Google Patents page. Similarly, the exact filing date is only provided for a few cases, primarily IPRs, while for district court cases, only the year of filing is inferable from the case number. The outcome or current status is also largely generalized as "litigation" or "Final Written Decision" for PTAB cases, with some IPRs showing "Not Instituted - Procedural."US patent 7161506, titled "Systems and methods for data compression such as content dependent data compression," has been involved in a number of litigation proceedings, primarily as the subject of inter partes reviews (IPRs) before the Patent Trial and Appeal Board (PTAB) and as a patent asserted in district court infringement lawsuits. Realtime Data LLC is the current and original assignee of the patent, and therefore typically the patent owner in IPRs and the plaintiff in infringement cases.

Here is a list of known litigation involving US patent 7161506:
