Original assignee

The original assignee of US patent 7061859 was Corrigent Systems Ltd., which later changed its name to Orckit-Corrigent Ltd. Corrigent Systems Ltd. was a developer of high-speed packet ring network equipment and solutions, aligning with the patent's subject matter of "Fast protection in ring topologies." It shipped products embodying the claims related to efficient fault protection in bidirectional ring networks.

Orckit-Corrigent Ltd. was acquired by EZChip (now part of NVIDIA through Mellanox) in 2011. The patent, however, was subsequently transferred out of the direct corporate lineage of Orckit-Corrigent in 2016. As of today, Orckit-Corrigent Ltd. is not operating as an independent entity holding this patent. The current assignee, as per Google Patents, is Quicker Connections LLC.

NPE / troll-pattern signals

1. Shell-entity transfer — Present. The transfer to ORCKIT IP, LLC (Reel 038529/0087, 2016-05-10) with the "IP, LLC" suffix, followed by transfers to SUCA LTD. (Reel 070953/0085, 2025-04-26) and then QUICKER CONNECTIONS LLC (Reel 071087/0641, 2025-05-12), are strong indicators of shell entities. Additionally, IP LITFIN US 2024 LLC (Reel 069230/0593, 2024-10-23), whose name suggests litigation finance, further supports this.

2. Known asserter in the chain — Present. QUICKER CONNECTIONS LLC is the current assignee and is noted in the Google Patents legal events section as being involved in active litigation in the Texas Eastern District Court (2:24-cv-01074) and an IPR proceeding (IPR2025-01088). Unified Patents also lists Quicker Connections LLC as an NPE.

3. Repeat correspondent across the chain — Present.

   • JAY S. HANDLER of Lerner, David, Littenberg, Krumholz & Mentlik, LLP, appears as correspondent for the security agreement (Reel 030033/0774, 2013-03-18), its release (Reel 030887/0983, 2013-07-26), and the assignment to Orckit IP, LLC (Reel 038529/0087, 2016-05-10).
   • WILLIAM S. PERRY of Kramer Levin Naftalis & Frankel LLP, appears as correspondent for the patent security agreement (Reel 069230/0593, 2024-10-23) and the assignment to Quicker Connections LLC (Reel 071087/0641, 2025-05-12).

4. Cascading transfers — Present. There were two assignments in quick succession in 2025: from ORCKIT IP, LLC to SUCA LTD. on 2025-04-26 (Reel 070953/0085) and then from SUCA LTD. to QUICKER CONNECTIONS LLC on 2025-05-12 (Reel 071087/0641). This constitutes multiple consecutive assignments within a short period (less than one month).

5. Pre-litigation transfer — Present. The assignment to QUICKER CONNECTIONS LLC was recorded on 2025-05-12 (Reel 071087/0641). An IPR challenge (IPR2025-01088) related to this patent had an effective date of 2025-06-02, which is less than one month after the assignment. While the Texas district court case (2:24-cv-01074) was filed earlier in 2024, the transfer to the current asserter, Quicker Connections LLC, occurred in close proximity to ongoing or impending assertion activities.

6. Bankruptcy fire-sale — Not present. There is no indication that the original assignee or subsequent operating companies entered bankruptcy proceedings that led to the sale of this patent.

7. Privateering — Unclear. While the patent originated from an operating company and is now held by an NPE, there is no public information to confirm whether the original operating company (or its successors) is actively funding or directing the current assertion efforts.

8. Defensive aggregator (anti-NPE) — Not present. The chain terminates with Quicker Connections LLC, which is an assertion entity, not a defensive aggregator.

Verdict

NPE — high confidence. This verdict is supported by multiple strong signals: the presence of multiple shell entities in the assignment chain (Orckit IP, LLC, Suca Ltd., Quicker Connections LLC, IP Litfin US 2024 LLC), the identification of Quicker Connections LLC as a known asserter actively engaged in litigation and IPRs related to this patent, the recurrence of specific correspondent attorneys (Jay S. Handler and William S. Perry) across several transfers, and the cascading transfers from Orckit IP, LLC to Suca Ltd. to Quicker Connections LLC in a short period in 2025. The final assignment to Quicker Connections LLC occurred just prior to an IPR filing against the patent, indicating a pre-litigation transfer strategy.
