NPE / troll-pattern signals

  1. Shell-entity transferNot present. The transfers are between Nokia Corporation and its subsidiary Nokia Technologies Oy. Both are operating entities with a clear business purpose.
  2. Known asserter in the chainNot present. Nokia Technologies Oy is not identified on public NPE lists such as RPX or Unified Patents. Nokia Technologies Oy actively develops and licenses technologies in various sectors, including mobile, consumer electronics, IoT, video services, and gaming.
  3. Repeat correspondent across the chainUnclear. The recorded assignment documents do not consistently list a correspondent, making it impossible to identify any recurring correspondent patterns.
  4. Cascading transfersNot present. There are only two assignments recorded, with a 12-year gap between them.
  5. Pre-litigation transferNot present. The last assignment to Nokia Technologies Oy was recorded in 2015. The first litigation identified for this patent (ITC Investigation 337-TA-1380) was filed on October 31, 2023. This gap of over eight years does not indicate a pre-litigation transfer.
  6. Bankruptcy fire-saleNot present. Nokia Corporation sold its mobile division to Microsoft in 2013 to avoid negative financial figures, but the company itself did not file for bankruptcy.
  7. PrivateeringNot present. There is no evidence from SEC filings or other public sources to suggest that Nokia Technologies Oy is acting on behalf of another operating company for assertion purposes.
  8. Defensive aggregator (anti-NPE)Not present. The patent remains with Nokia Technologies Oy, an entity that engages in patent licensing and assertion, rather than a defensive aggregator like RPX or Allied Security Trust.

Verdict

Operating-company assertion

This verdict is based on the patent's ownership chain remaining within the Nokia corporate structure. The original assignee, Nokia Inc. (part of Nokia Corporation), was a product-shipping company. The current assignee, Nokia Technologies Oy, is an active subsidiary of Nokia Corporation, involved in research, development, and patent licensing across various technology sectors. Furthermore, Nokia Technologies Oy has initiated infringement litigation involving this patent (e.g., ITC Investigation 337-TA-1380 filed on October 31, 2023), indicating an assertion strategy by an operating company against perceived infringers who are actual competitors in the market for video-capable electronic devices.
