PS400

What this record means

The record shows that the mark “PS400” is no longer active; it was cancelled on March 31 2023 because the registrant, Miller Weldmaster Corporation, did not file a required Section 8 declaration. The mark had been registered on September 20 2016 in the Principal Register for heat‑sealing machines used to bond, seal, and fuse plastic and industrial fabrics. A similar name would raise the closest concern in the same technical field of industrial machinery and equipment. The record does not give the owner control over every use of the wording, only over the specific goods listed. The prosecution history indicates a standard examination process that ended with registration and later cancellation; no supplemental registration or opposition actions appear. The latest event is the cancellation notice in March 2023, and no enforcement activity is recorded. If you plan to use a similar name for heat‑sealing equipment, you should be aware that the cancelled registration still signals a prior claim in that niche.
