SLOPE BLOCK MARK IV

What this record means

The record shows a live Principal Register registration for “SLOPE BLOCK MARK IV,” owned by HENGESTONE HOLDINGS, INC., a Delaware company, and the registration was renewed as of the status date on February 17 2026. The protection is limited to the class 019 description “blocks for retaining walls,” with the first use in commerce dated 1988, so a similar name used on building‑material products such as retaining‑wall blocks would be the closest area of concern. The record does not give the owner control over every use of the words “slope,” “block,” or “mark” in unrelated fields. Because the mark sits on the Principal Register, there is no supplemental‑register sequence shown in the prosecution history. The latest meaningful event is the renewal reflected in the status date, and the supplied history contains no oppositions, cancellations or other enforcement actions. I'd treat this as a meaningful concern if you plan to market similar retaining‑wall blocks under a comparable name.
