Earlier this year, on April 24, 2024, 80 issued US patents moved from Level 3 Communications (acquired in 2017 by Lumen Technologies (f/k/a CenturyLink)) to Delaware entity Sandpiper CDN, LLC, in an assignment recorded two days later. On May 31, 2024, another transfer, recorded on June 19, popped up, showing that Sandpiper CDN added three dozen more patent assets to its holdings, from the same source. Assignment records subsequently made public indicate that May 31 was a much busier day in this regard than previously known.
