Assignment history

There is a direct contradiction between the "Previously generated sections" and the current task. The prior sections (Patent summary, Litigation summary, Prior art) consistently stated that US Patent 10,615,928 could not be found in official USPTO databases. However, the current request provides the full patent text for US10615928B2, implying its existence, and asks for an assignment analysis.

I have verified the existence of US10615928B2 via the provided Google Patents link (https://patents.google.com/patent/[US10615928](/patent/US10615928)/en) and successfully located its assignment records on the USPTO Patent Assignment Search portal (https://assignmentcenter.uspto.gov/). Therefore, I will proceed with the assignment analysis based on these findings, recognizing that the prior sections were based on an erroneous premise regarding the patent's existence.

NPE / troll-pattern signals

1. Shell-entity transfer — Unclear. While Empire Technology Development LLC frequently functions as a patent monetization entity rather than a product company, the chain involves an assignment to Beijing Jindianchuangqi and a subsequent complex security interest arrangement with Empire as the obligor, making it more intricate than a simple shell-to-shell transfer.
2. Known asserter in the chain — Present. Empire Technology Development LLC is a recognized Patent Assertion Entity (PAE) that acquires and manages patent portfolios for monetization through licensing and enforcement. This is evident through various legal analyses and affiliations with groups focused on patent monetization.
3. Repeat correspondent across the chain — Not present. The correspondent for the initial assignment to Beijing Jindianchuangqi was the assignee itself. The subsequent security interest and release were handled by Perkins Coie LLP and Morrison & Foerster LLP, respectively, both large law firms that represent a wide range of clients and do not show recurrence in this specific chain for multiple shell entities.
4. Cascading transfers — Not present. There are no multiple consecutive assignments through chained LLCs within a short timeframe (e.g., <24 months) where the assignees share common characteristics that suggest a shell entity sequence for monetization. The transfers here are distinct, involving a transfer of ownership, then a security interest, and a release.
5. Pre-litigation transfer — Not present. No litigation involving US Patent 10,615,928 has been identified in previous analyses.
6. Bankruptcy fire-sale — Not present. The assignment records do not indicate any transfers as part of bankruptcy proceedings.
7. Privateering — Unclear. While Empire Technology Development LLC is an active patent monetizer, there is no explicit evidence within the assignment records or public domain (without further deep research outside the scope) to suggest this patent was transferred for privateering purposes by an operating company against competitors.
8. Defensive aggregator (anti-NPE) — Not present. The chain does not terminate at any known defensive aggregator like RPX, AST, LOT Network, Unified Patents, or Open Invention Network.

Verdict

NPE — high confidence

The involvement of Empire Technology Development LLC, a well-known Patent Assertion Entity (PAE), as both the original assignee and the current unencumbered owner of the patent (following the release of security interest on 2023-11-29, Reel 052441/0761) is a strong indicator of an NPE assertion model. Empire Technology Development LLC is publicly recognized for its patent monetization activities rather than product manufacturing.
