Assignment history

Inventors

• Francis daCosta: Employer not explicitly stated in the patent document for the filing date of 2020-09-21, but the original assignee is Dynamic Mesh Networks Inc.
• Sriram Dayanandan: Employer not explicitly stated in the patent document for the filing date of 2020-09-21, but the original assignee is Dynamic Mesh Networks Inc.

There is no information within the patent document to determine if inventors departed the original assignee within 12 months of filing.

Original assignee

The entity named on the issued patent US11368537B2 as the Original Assignee is Dynamic Mesh Networks Inc.

The patent describes a "high performance wireless network" based on "smart" communication devices (Access Points) providing embedded intelligence, application awareness, and cost-effective distributed sensing and control for networks. It specifically mentions applications like voice/data access for warehouses, factory floors, process control equipment, and home networking for voice/data/video streaming. This strongly suggests that Dynamic Mesh Networks Inc. would likely be involved in developing or licensing technology for wireless networking products.

Regarding whether they shipped a product embodying the claims, the patent mentions "a self-standing executable... has been produced" and "mesh and load balancing algorithms have been successfully ported to run on the hardware depicted in FIG. 15," indicating prototype or development work. However, there is no explicit statement within the patent text confirming commercial product shipment.

The current status of Dynamic Mesh Networks Inc. is operating as of the latest assignment records, where it is listed as both an assignor and assignee in 2025.

NPE / troll-pattern signals

1. Shell-entity transfer — Unclear. The patent expired shortly after issuance (anticipated expiration May 8, 2023, issue date June 21, 2022). Transfers of an expired patent are unusual for assertion. Dynamic Mesh Networks Inc. is the original assignee and the ultimate assignee after a series of transfers. Whether Advanced Cybernetics Group Inc., Abacus Controls Group, Inc., or Chirp Networks Inc. are shell entities or operating companies is not determinable from the patent text or assignment records alone. The rapid transfers in 2025 after expiration are notable.
2. Known asserter in the chain — Not Present. None of the assignees (Dynamic Mesh Networks Inc., Advanced Cybernetics Group Inc., Abacus Controls Group, Inc., Chirp Networks Inc.) match known public NPE lists based on the provided information.
3. Repeat correspondent across the chain — Present. Michael D. Rezmuch (15500 N. 53RD AVENUE, SUITE D, GLENDALE, AZ 85306) is listed as the correspondent for all four recorded assignments on reel 058097/0861, 058097/0862, 058097/0863, and 058097/0864. This recurrence across multiple transfers within a short period is a strong signal.
4. Cascading transfers — Present. There are four consecutive assignments occurring on 2025-08-11 and 2025-08-12 (within 2 days), including transfers to Dynamic Mesh Networks, to Chirp Networks, and then back to Dynamic Mesh Networks. This rapid succession of transfers within a very short timeframe, handled by the same correspondent, is a strong signal. (Reel 058097/0861, 058097/0862, 058097/0863, 058097/0864).
5. Pre-litigation transfer — Present. The assignments occurred on 2025-08-11 and 2025-08-12 (Reel 058097/0861, 058097/0862, 058097/0863, 058097/0864). The patent text indicates that US district court cases were filed in Texas Eastern District Court and California Northern District Court in 2025. Given the timing of the assignments (August 2025) and the filing of litigation in 2025, it is highly likely these transfers occurred within 6 months (or even immediately before) the lawsuits were filed, indicating a pre-litigation transfer designed to set up assertion.
6. Bankruptcy fire-sale — Not present. There is no indication from the patent text or assignment records of a bankruptcy proceeding involving the assignors.
7. Privateering — Unclear. While the transfers might enable assertion, there's no public information in the patent or assignment records to suggest an operating company is using an NPE to assert on its behalf against competitors.
8. Defensive aggregator (anti-NPE) — Not present. The chain does not end at a known defensive aggregator.

Verdict

NPE — high confidence

The combination of cascading transfers (four assignments in two days in August 2025) and the timing of these transfers just before or concurrent with the filing of infringement lawsuits in 2025 (as noted in the Google Patents legal status section) are strong indicators of an NPE assertion strategy. Furthermore, the same correspondent, Michael D. Rezmuch, handled all four rapid transfers, suggesting a coordinated effort. This pattern is particularly unusual given the patent's anticipated expiration date of May 8, 2023, suggesting the assertion relates to past infringement.
