Original assignee

Zest Labs Inc. (the AgTech company, not the supplement company) was an operating company focused on developing post-harvest freshness management services and solutions for the food distribution and delivery system, with products such as Zest Fresh. Its primary line of business involved cold chain monitoring and predictive analytics to improve food quality and reduce waste for perishable food products. Zest Labs Inc. was a subsidiary of Ecoark Holdings, Inc., and PitchBook indicates an acquisition by RiskOn International in 2013, though the company continued operations and filed this patent in 2021, suggesting its status as an operating entity at the time of filing for this patent.

NPE / troll-pattern signals

  1. Shell-entity transfernot present. The patent transferred from the individual inventors to Intelleflex Corporation, which then underwent a name change to Zest Labs, Inc., an operating company. There is no evidence of a transfer to a licensing-only shell entity.
  2. Known asserter in the chainnot present. Neither Intelleflex Corporation nor Zest Labs, Inc. are identified as known high-frequency patent asserters.
  3. Repeat correspondent across the chainpresent. Brent W. LaBarge, Esq. of 20400 Stevens Creek Blvd., Suite 350, Cupertino, CA 95014 is listed as the correspondent for both recorded assignment entries (Reel 056461/0810 and Reel 056461/0811).
  4. Cascading transfersnot present. The two recorded events represent a direct assignment from inventors followed by a name change, both executed and recorded on the same dates, not a series of transfers through chained LLCs.
  5. Pre-litigation transfernot present. The transfers occurred during the patent's prosecution phase, well before any potential litigation, and no litigation information is available for this patent.
  6. Bankruptcy fire-salenot present. While Zest Labs (the AgTech company) was acquired in 2013, the assignments for this patent reflect an inventor assignment and a corporate name change, not a sale due to bankruptcy proceedings.
  7. Privateeringnot present. There is no indication of an operating company transferring this patent to an NPE for assertion against competitors.
  8. Defensive aggregator (anti-NPE)not present. The patent chain does not terminate at a known defensive aggregator like RPX or AST.

Verdict

Insufficient data.
The assignment record for US12008509B2 consists solely of an initial assignment from the inventors to Intelleflex Corporation, immediately followed by a recorded change of name from Intelleflex Corporation to Zest Labs, Inc., both executed on 2021-06-23 and recorded on 2021-07-28 (Reel 056461/0810, Reel 056461/0811). While a repeat correspondent is noted for these two related events, there are no subsequent transfers or other signals indicative of an NPE. The patent appears to remain with the original operating entity (under its new name) that filed for it.
