Patent 7885243

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

  • Francis da Costa
  • Sriram Dayanandan
    • Their employer at the time of filing (May 19, 2008) was Mesh Dynamics Inc., the original assignee. No unusual patterns are immediately evident.

Original assignee

Mesh Dynamics Inc. was the original assignee. The company developed wireless mesh networking solutions, as described in the patent, for enterprise and home environments, supporting voice, video, and data traffic. They appear to have shipped products embodying the claims, specifically "smart" Access Points (AP) with embedded intelligence for distributed control. Mesh Dynamics Inc. transferred the patent to Dynamic Mesh Networks, Inc. in 2014, suggesting an acquisition or corporate restructuring, though its current operating status under its original name is unclear. Dynamic Mesh Networks, Inc. is now the entity actively asserting the patent.

NPE / troll-pattern signals

  1. Shell-entity transfer — Present. The transfer to Chirp Networks Inc. and then immediately back to Dynamic Mesh Networks, Inc. on the same day (2025-08-12, Reel 062638/0003 and 062638/0004) strongly indicates a transient transfer, often for legal or financial maneuvering rather than genuine product development by Chirp Networks Inc.
  2. Known asserter in the chain — Present. Dynamic Mesh Networks, Inc. is actively asserting this patent, as evidenced by multiple district court cases filed in 2025 in the Texas Eastern and California Northern District Courts and an IPR challenge initiated by Unified Patents (IPR2025-01304). This indicates Dynamic Mesh Networks, Inc. operates as an assertion entity.
  3. Repeat correspondent across the chain — Present. Elizabeth B. Flanagan of Daniel Law Offices, P.A. served as the correspondent for four consecutive assignments (Reel 062638/0001, 062638/0002, 062638/0003, 062638/0004) occurring on 2025-08-11 and 2025-08-12. This recurrence on rapid transfers is a strong signal.
  4. Cascading transfers — Present. Three assignments occurred on 2025-08-11, followed by two more on 2025-08-12 (Reel 062638/0001, 062638/0002, 062638/0003, 062638/0004). This sequence of rapid, consecutive transfers involving different entities over a two-day period, particularly the back-and-forth between Dynamic Mesh Networks, Inc. and Chirp Networks Inc., is highly indicative of cascading transfers.
  5. Pre-litigation transfer — Present. The flurry of assignments on 2025-08-11 and 2025-08-12 (Reel 062638/0001, 062638/0002, 062638/0003, 062638/0004) occurred in the same year as, and in very close proximity to, the filing of multiple infringement lawsuits involving this patent in 2025. This strong temporal correlation indicates these transfers were likely orchestrated in anticipation of, or in direct support of, litigation.
  6. Bankruptcy fire-sale — Not present. No evidence suggests any assignor or assignee in the chain underwent bankruptcy proceedings related to the patent transfers.
  7. Privateering — Unclear. While Dynamic Mesh Networks, Inc. is asserting the patent, it is not definitively clear from the available records whether this assertion is on behalf of a specific operating company against its competitors.
  8. Defensive aggregator (anti-NPE) — Not present. The patent ultimately resides with Dynamic Mesh Networks, Inc., an entity engaged in assertion, and has not been transferred to a known defensive aggregator.

Verdict

NPE — high confidence

The patent exhibits strong NPE patterns, including multiple rapid "cascading transfers" (Reel 062638/0001, 062638/0002, 062638/0003, 062638/0004) executed and recorded on consecutive days in August 2025. These transfers were overseen by a "repeat correspondent" (Elizabeth B. Flanagan, Daniel Law Offices, P.A.) and closely coincided with the filing of infringement lawsuits in 2025, establishing Dynamic Mesh Networks, Inc. as a "known asserter". The fleeting transfer to and from Chirp Networks Inc. on the same day further points to procedural moves typical of assertion entities.
