NPE / troll-pattern signals

  1. Shell-entity transferPresent. The inventors first transferred the patent to Terranco, Limited Liability Company (Reel 017997/0118), a holding entity, which then transferred it to Intellectual Ventures I LLC (Reel 025539/0789).

  2. Known asserter in the chainPresent. The current assignee of record is Intellectual Ventures I LLC (Reel 025539/0789), one of the most widely recognized patent assertion entities (NPEs).

  3. Repeat correspondent across the chainNot present. The two recorded assignments list different correspondents.

  4. Cascading transfersNot present. The transfers occurred approximately four years apart.

  5. Pre-litigation transferPresent. The assignment to Intellectual Ventures I LLC was recorded on 2010-12-07 (Reel 025539/0789). The first infringement lawsuit on this patent, Intellectual Ventures I LLC v. Symantec Corp., was filed the very next day on 2010-12-08 in the District of Delaware (Case 1:10-cv-01067). This timing indicates the transfer was recorded to perfect legal standing immediately before litigation commenced.

  6. Bankruptcy fire-saleNot present. There is no evidence of a bankruptcy proceeding in the assignment chain.

  7. PrivateeringNot present. The original assignors were the inventors, not an operating company offloading patents for assertion against its competitors.

  8. Defensive aggregator (anti-NPE)Not present. The chain terminates with a known patent assertion entity.

Verdict

NPE — high confidence

The assignment chain shows a clear and deliberate path to monetization through assertion, not commercialization. The patent was moved from the inventors to a holding company (Terranco, LLC) and then acquired by Intellectual Ventures, a well-known NPE (Reel 025539/0789). The final assignment was recorded just one day before the first lawsuit was filed, demonstrating a clear intent to litigate.
