NPE / troll-pattern signals
Shell-entity transfer — Present. 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).
Known asserter in the chain — Present. The current assignee of record is Intellectual Ventures I LLC (Reel 025539/0789), one of the most widely recognized patent assertion entities (NPEs).
Repeat correspondent across the chain — Not present. The two recorded assignments list different correspondents.
Cascading transfers — Not present. The transfers occurred approximately four years apart.
Pre-litigation transfer — Present. 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.
Bankruptcy fire-sale — Not present. There is no evidence of a bankruptcy proceeding in the assignment chain.
Privateering — Not present. The original assignors were the inventors, not an operating company offloading patents for assertion against its competitors.
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.
