CROSSFLOWSerial 73838787 · Principal Register
Dead · Cancelled
Owner: CSM ENVIRONONMENTAL SYSTEMS, INC.
Class 011 -
Filed Nov 13, 1989
Registered Aug 14, 1990
The record shows that the mark “CROSSFLOW” is no longer active; it was cancelled on January 22, 2016 because the registrant, CSM ENVIRONONMENTAL SYSTEMS, INC., failed to file a Section 8 declaration. The mark had been registered on the Principal Register in 1990 for the specific goods of air filters and combustion surfaces used in incinerator systems. Because the cancellation was due to a maintenance failure, the record does not indicate that the owner has abandoned the mark entirely, but it also does not provide any current protection. The goods listed are quite narrow, so a similar name used for unrelated products would raise a far‑removed concern, while a name used in the same incinerator‑filter niche would be the closest area of risk. No oppositions, cancellations after publication, or court actions appear in the supplied history, so the record shows no visible enforcement activity. For someone thinking of a similar name, the cancellation suggests that the mark is no longer enforceable, but the specific goods remain a potential point of concern if the new use overlaps with incinerator filters.

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.
