XCELL

What this record means

The record shows that the mark “XCELL” is live and registered on the Principal Register under serial 86887316, owned by Repligen Corporation, a Delaware corporation. The registration covers 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 bioreactors in upstream bioprocessing. A similar name would raise the closest concern in the same niche of laboratory and biopharmaceutical equipment. The record does not give the owner control over every use of the word “XCELL” outside that specific field. The latest maintenance event is the registration itself on December 14, 2021; no further renewal or enforcement actions appear in the supplied history. With no visible oppositions or cancellations, the record shows no enforcement activity. If you plan to use a similar name in the same or related scientific equipment area, you should be aware of this active registration and its narrow scope.
