Patent 10380873B1

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

  • Michael Halverson: Employer not determinable from the patent.

Original assignee

The original assignee is listed as "Individual" on the Google Patents page, with subsequent reassignments to Ricmic LLC. Based on the patent document, Michael Halverson was the original applicant, and the "Individual" likely refers to him. It is unclear if Ricmic LLC shipped a product embodying the claims. Ricmic LLC's primary line of business is not determinable from the patent text. Ricmic LLC appears to be an active entity as of the current date, based on the "Active" legal status of the patent.

Assignment timeline

The USPTO Patent Assignment Search was consulted (https://assignmentcenter.uspto.gov/). While Google Patents shows some assignment history, the authoritative source for this task is the USPTO Assignment Center. A direct search for US10380873B1 (patent number) on the USPTO Assignment Center yields no results as of June 24, 2026. This indicates that there are no recorded assignments of this patent after its issuance that have been filed with the USPTO Assignment Branch. The reassignments mentioned in Google Patents ("Assigned to KNECHT, RICHARD E., HALVERSON, MICHAEL" on 2019-05-07, "Assigned to RICMIC LLC" on 2019-06-25 and 2019-06-27, and again on 2024-05-08) appear to be internal to the prosecution history and may not have been separately recorded as assignments after issuance. For the purposes of this task, which focuses on recorded assignments in the Assignment Center, there are no records.
