SHOCK SUBSerial 72121549 · Principal Register
Dead · Cancelled
Owner: SMITH INTERNATIONAL, INC.
Class 007 -
Filed Jun 07, 1961
Registered Mar 12, 1963
The record shows that the mark “SHOCK SUB” is no longer active; it was cancelled on April 1, 2016 because the registrant, SMITH INTERNATIONAL, INC., did not file a required declaration. The mark had been registered on the Principal Register in 1963 for the specific goods of tubular devices interposed in rotary drill strings, such as cushions between drill bits and collars to reduce vibration. Because the cancelled status removes the legal protection, the record does not give the owner control over every use of the wording. The prosecution history indicates that the mark was originally registered under Section 8 and later combined with a Section 9 filing, but no Supplemental Register activity is shown. No oppositions, cancellations, or court actions appear in the supplied history, so there is no visible enforcement signal. For someone considering a similar name, the closest concern would be in the drilling equipment niche; outside that area the risk is lower, but the mark’s past registration still suggests that the owner once claimed rights to that specific phrase.

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.
