XCELL ATFSerial 86940131 · Principal Register
Live · Registered
Owner: Repligen Corporation
Class 009 - Electrical & Scientific Apparatus
Filed Mar 15, 2016
Registered Feb 11, 2020
The record shows that “XCELL ATF” is a live, registered mark on the Principal Register owned by Repligen Corporation, a Delaware corporation. The mark protects scientific apparatus and instruments for laboratory use and in the processing of biopharmaceuticals, specifically cell‑retention devices for alternating tangential flow used with an electronic operating control system for upstream bioprocessing. A similar name used in that exact or closely related field would raise the closest record‑based concern. The record does not give the owner control over every use of the wording “XCELL ATF”; it is limited to the goods listed. The prosecution history shows a straightforward allowance and registration, with no Supplemental Register involvement. The latest meaningful event is the acceptance of the Section 8 and 15 maintenance declarations on May 4, 2026, keeping the mark active. No enforcement actions appear in the supplied history. For someone considering a similar name in the same or a related field, the risk of conflict is meaningful.

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.
