INSIDIOUS

What this record means

The record shows that INSIDIOUS is a cancelled Principal Register mark owned by James Massey; the registration was cancelled on Dec 7 2018 because the required Section 8 declaration was not filed. The protection that existed covered clothing – specifically tops, bottoms, underwear, footwear, headwear, dresses, jackets, coats, belts, neckwear, beachwear, and sleepwear – so a later use of the same word on similar apparel would be the closest record‑based concern, while uses on unrelated goods would be farther from the scope shown. The record does not give the owner control over every possible use of the word “insidious.” No Supplemental Register filing appears, and the prosecution history simply tracks the normal allowance, statement‑of‑use filings and the eventual Section 8 cancellation. The latest meaningful event is the cancellation notice on Dec 7 2018, and the supplied history shows no oppositions, cancellations beyond this or other enforcement actions. I'd treat this as a moderate concern if you plan a clothing line with the same name.
