Inventors

The sole named inventor for US Patent 11329655 is Nima Badizadegan. At the time of filing, Nima Badizadegan was the assignor to HFT Solutions LLC. The patent text itself does not explicitly state an employer for the inventor, but the assignment record (detailed below) indicates the transfer of the inventor's interest to HFT Solutions LLC, suggesting they were the original assignee/employer.

Original assignee

The original assignee named on US Patent 11329655 is HFT Solutions LLC.

Regarding whether they ship a product embodying the claims and their primary line of business:
HFT Solutions LLC is a subsidiary of Network-1 Technologies, Inc. ("Network-1"), a company engaged in acquiring, developing, licensing, and monetizing intellectual property. HFT Solutions LLC does not appear to ship products embodying the claims itself. Instead, its primary line of business, as a subsidiary of Network-1, is the licensing and monetization of its patent portfolio, specifically in the high-frequency trading (HFT) sector. The patent itself focuses on minimizing latency in Field Programmable Gate Arrays (FPGAs) for high-frequency trading, which is a critical aspect of such operations.

HFT Solutions LLC has initiated patent infringement lawsuits against firms engaged in high-frequency trading activities, alleging infringement of its patent portfolio, including technology related to FPGAs and clock domain management. These lawsuits indicate that HFT Solutions LLC is an asserting entity.

Its current status is operating as a subsidiary of Network-1 Technologies, Inc., actively involved in patent licensing and litigation.

NPE / troll-pattern signals

  1. Shell-entity transfer — Present.

    • Evidence: The patent was assigned to HFT Solutions, LLC. HFT Solutions, LLC is a newly formed subsidiary of Network-1 Technologies, Inc., whose stated business is "acquiring, developing, licensing, and monetizing intellectual property". This indicates a transfer to an entity primarily focused on licensing rather than product development.
    • Citation: Reel 057041/0048 (executed 2022-04-04 / recorded 2022-04-04) and Network-1 Technologies, Inc. press release from March 28, 2022.

  2. Known asserter in the chain — Present.

    • Evidence: HFT Solutions, LLC is a subsidiary of Network-1 Technologies, Inc. Network-1 is a known publicly traded company engaged in patent licensing and assertion. Information indicates HFT Solutions LLC has initiated patent infringement lawsuits against Optiver US LLC and Citadel Securities LLC regarding its HFT patent portfolio.
    • Citation: Network-1 Technologies, Inc. press release from March 28, 2022 and court filings.

  3. Repeat correspondent across the chain — Not present.

    • Evidence: Only one assignment is recorded, and the correspondent, MICHAEL T RYAN, RYAN, MASON & SHARP, LLP, has not recurred within this specific chain.
    • Citation: Reel 057041/0048 (correspondent: MICHAEL T RYAN, RYAN, MASON & SHARP, LLP).

  4. Cascading transfers — Not present.

    • Evidence: Only one assignment is recorded from the inventor to the initial assignee.
    • Citation: Reel 057041/0048.

  5. Pre-litigation transfer — Unclear.

    • Evidence: The assignment from the inventor to HFT Solutions LLC occurred on April 4, 2022. The first known litigation related to the HFT Solutions portfolio (though not specifically this patent in the cited articles) was initiated in December 2024 (HFT Solutions, LLC v. Citadel Securities LLC) and September 2025 (HFT Solutions, LLC v. Optiver US LLC). While the transfer happened before litigation, the time gap (over 24 months) makes it difficult to definitively classify as "pre-litigation transfer" in the typical narrow sense of 6 months. However, the intent to license/monetize was clearly stated by Network-1 at the time of portfolio acquisition in March 2022.
    • Citation: Reel 057041/0048 (executed 2022-04-04), HFT Solutions, LLC v. Citadel Securities LLC, No. 1:2024cv13213 (filed December 2024), and Network-1's announcement of acquiring the HFT patent portfolio in March 2022 and commencing licensing activities.

  6. Bankruptcy fire-sale — Not present.

    • Evidence: No indication of bankruptcy proceedings for the assignor.
    • Citation: Not applicable.

  7. Privateering — Unclear.

    • Evidence: While HFT Solutions LLC is asserting patents related to high-frequency trading, and Network-1 acquires portfolios to monetize them, there is no direct evidence from SEC filings or other sources explicitly stating that an operating company transferred this patent to HFT Solutions LLC to assert on its behalf against competitors. The initial transfer was from the inventor.
    • Citation: Not applicable.

  8. Defensive aggregator (anti-NPE) — Not present.

    • Evidence: The current assignee, HFT Solutions LLC (a Network-1 subsidiary), is an asserting entity, not a defensive aggregator.
    • Citation: Network-1's stated business model and ongoing litigation.

Verdict

NPE — high confidence

The verdict is high confidence NPE due to two strong signals: the transfer to a known asserter (HFT Solutions LLC, a subsidiary of Network-1 Technologies, Inc.) and the clear indication that HFT Solutions, LLC operates as a shell entity focused on patent licensing and litigation rather than product development. The publicly stated business model of Network-1, which owns HFT Solutions LLC, is the acquisition and monetization of intellectual property, and HFT Solutions LLC has engaged in patent infringement lawsuits.
