NPE / troll-pattern signals

  1. Shell-entity transfer — present. The patent was transferred from Flextronics AP LLC (an operating company) to Multimedia Technologies Pte Ltd on 2023-01-18 (Reel 060933/0285). Multimedia Technologies Pte Ltd appears to be a licensing-only entity, based on its name and typical patterns of patent assertion.
  2. Known asserter in the chain — present. Multimedia Technologies Pte Ltd has been identified as a high-frequency plaintiff by Unified Patents.
  3. Repeat correspondent across the chain — not present. John S. Begin of Flextronics was the correspondent for the 2014-03-06 assignment (Reel 031952/0150). Nicole M. De Cesare of Bayswater Law was the correspondent for the 2023-01-18 assignment (Reel 060933/0285). There is no recurrence of correspondents in this chain.
  4. Cascading transfers — not present. Only two assignments are recorded for this patent, and they are separated by several years.
  5. Pre-litigation transfer — unclear. While Multimedia Technologies Pte Ltd is a known asserter, the first litigation for this patent listed on Google Patents is dated 2022-10-14, which predates the assignment to Multimedia Technologies Pte Ltd on 2023-01-18. However, the Darts-ip litigation link states "First worldwide family litigation filed" on an unknown date prior to the current date. Given the 2023 transfer to a known asserter, it is possible further litigation or intent to litigate was present around the time of transfer.
  6. Bankruptcy fire-sale — not present. There is no indication that Flextronics AP LLC filed for bankruptcy.
  7. Privateering — unclear. While a transfer from an operating company to a known NPE is observed, there is no public information in SEC filings or reports explicitly indicating a privateering arrangement for this specific patent.
  8. Defensive aggregator (anti-NPE) — not present. The chain terminates with Multimedia Technologies Pte Ltd, which is a known asserter, not a defensive aggregator.

Verdict

NPE — high confidence
The transfer of the patent from an operating company (Flextronics AP LLC) to a known patent asserter (Multimedia Technologies Pte Ltd) as recorded on 2023-01-18 (Reel 060933/0285) is a strong indicator. Additionally, Multimedia Technologies Pte Ltd is recognized as a high-frequency plaintiff by Unified Patents.
