Assignment history

Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.

Inventors

Michael Pratt (Fast IP LLC)
Craig Cheney (Fast IP LLC)

Original assignee

Fast IP LLC. The patent abstract and description indicate that Fast IP LLC is involved in developing rapid-entry footwear, which is consistent with the "Kizik" brand of hands-free shoes mentioned in the prior art analysis. Kizik Design, LLC is listed as a plaintiff in the ongoing litigation, alongside Fast IP, LLC, suggesting a close relationship or a product embodiment by Kizik Design, LLC. Fast IP LLC's primary line of business appears to be intellectual property holding and licensing related to rapid-entry footwear technology. Its current status is operating, as it is actively involved in litigation as a plaintiff.

NPE / troll-pattern signals

Shell-entity transfer — unclear. While Fast IP, LLC is primarily an IP holding and licensing entity, it is directly linked to Kizik Design, LLC, which appears to be an operating company selling products. The transfer from inventors to Fast IP, LLC (Reel 061142/0695) is a common initial step for both operating companies and NPEs. The subsequent securitization to Siena Lending Group LLC (Reel 065874/0252) involves multiple Fast IP-related entities, further complicating a simple "shell-entity" assessment at this stage.
Known asserter in the chain — not present. Siena Lending Group LLC is a financial institution and not a known patent asserter. Fast IP, LLC is not on common public NPE lists like Marathon Patent Group or Intellectual Ventures.
Repeat correspondent across the chain — present. Jeffrey D. Myers of Kirton McConkie PC is listed as the correspondent for both the initial assignment from inventors to Fast IP, LLC (Reel 061142/0695) and the security interest filing with Siena Lending Group LLC (Reel 065874/0252). The provided context states this correspondent recurs across this patent's chain and other patents tracked on this site, which is a strong signal for a focused IP strategy.
Cascading transfers — not present. There are only two recorded transactions, occurring more than two years apart, and not involving multiple chained LLCs.
Pre-litigation transfer — not present. The most recent assignment (security interest to Siena Lending Group LLC, Reel 065874/0252) was recorded on 2025-06-13. The first infringement suit was filed in July 2025, which is within the 6-month window. However, this was a securitization, not a transfer of ownership for assertion purposes. The initial assignment from inventors to Fast IP, LLC was in 2023, well before litigation.
Bankruptcy fire-sale — not present. There is no indication that the patent was acquired through a bankruptcy proceeding.
Privateering — unclear. While Fast IP, LLC is asserting the patent, and Kizik Design, LLC appears to be an operating company, the nature of their relationship (whether Kizik is directing the litigation via Fast IP) is not definitively clear from the assignment records alone.
Defensive aggregator (anti-NPE) — not present. The chain does not terminate at any known defensive aggregator.

Verdict

NPE — moderate confidence. While there isn't a direct transfer to a well-known NPE, the presence of a repeat correspondent (Jeffrey D. Myers, Kirton McConkie PC on Reel 061142/0695 and Reel 065874/0252) across the chain, combined with Fast IP, LLC's role as an IP holding and licensing entity, suggests a focused strategy on patent assertion rather than direct product manufacturing. The securitization also indicates a leveraged IP asset.
