NPE / troll-pattern signals

  1. Shell-entity transfer — present. The patent was assigned from Raytheon Company, a major operating company, to "OL SECURITY LIMITED LIABILITY COMPANY". The name "OL SECURITY LIMITED LIABILITY COMPANY" with "LLC" suffix strongly suggests a licensing-only entity. Further, Unified Patents lists OL Security LLC as an NPE.
  2. Known asserter in the chain — present. The current assignee, OL Security LLC, is identified as a Non-Practicing Entity (NPE) by Unified Patents.
  3. Repeat correspondent across the chain — not present. Different correspondents are listed for the two recorded assignments. R. DENNIS CREWS for the initial assignment and BARRY F. NOONAN for the assignment to OL Security LLC.
  4. Cascading transfers — not present. Only two assignments are recorded, separated by several years.
  5. Pre-litigation transfer — unclear. While the transfer to OL Security LLC occurred in 2012, no specific litigation dates are immediately available in the provided text to determine if this transfer was within 6 months of the first suit. However, Google Patents notes "Family has litigation".
  6. Bankruptcy fire-sale — not present. Raytheon Company is an operating company and no bankruptcy filing is indicated.
  7. Privateering — unclear. There's no explicit information in the provided text or typical public records to definitively determine if Raytheon transferred the patent to OL Security LLC to assert on its behalf against competitors.
  8. Defensive aggregator (anti-NPE) — not present. The chain does not terminate at any known defensive aggregator.

Verdict

NPE — high confidence. The patent was transferred from an operating company (Raytheon Co.) to an entity named "OL SECURITY LIMITED LIABILITY COMPANY", which is a strong indicator of a shell entity. This is further supported by OL Security LLC being identified as a known Non-Practicing Entity (NPE) by Unified Patents. The presence of these two strong signals points to an NPE assertion model.
