CROSSFLOWSerial 90665220 · Principal Register
Dead · Withdrawn
Owner: SONENDO, INC.
Class 010 -
Filed Apr 22, 2021
The record shows that the mark “CROSSFLOW” is dead, having been abandoned by its owner, SONENDO, INC., a Delaware corporation. The abandonment was filed as an express abandonment on June 18 2021, and the application was never registered. The only goods listed are dental sonic energy delivery systems and related hand‑held applicators for use in dental or endodontic procedures, all in class 010. Because the mark is no longer active, it does not give the owner control over the word “Crossflow” in any other context. The prosecution history shows the application was entered in April 2021, data entered in July 2021, and the abandonment was processed in June 2021. No oppositions, cancellations, or other enforcement actions appear in the supplied history. For someone looking to use a similar name, the closest concern would be in dental or endodontic equipment, but the abandoned status means there is no active claim to the term.

The way I'd use it, honestly, is as the thing you attach when a bank, a marketplace, or a co-founder asks "are we clear on the name". It answers in one page.
