Verdict

Operating-company assertion.
The patent was granted to Tethrd LLC, an active operating company that markets products embodying the claimed invention. The sole recorded assignment is a transfer of inventor interest to Tethrd LLC (Reel 072280/0145). Although litigation is noted in the patent history, it commenced in 2024, prior to the inventor assignment's recording date in 2025, indicating Tethrd LLC was already the asserting entity.
