FILTER SOCKSerial 87944476 · Principal Register
Dead · Refused
Owner: Siltworm, Inc.
Class 011 -
Filed Jun 01, 2018
The record shows that the mark “FILTER SOCK” is dead, having been abandoned because the applicant failed to respond to an Office action. The owner listed is Siltworm, Inc., a corporation organized in Indiana. The goods described in the application are a rolled erosion or sediment control filter device, a very specific type of construction or environmental control equipment. A similar name used for a product or service that falls within that same niche—such as a device that filters sediment in construction sites—would raise the closest record‑based concern. The record does not give the owner control over every use of the words “filter” or “sock” in unrelated contexts. The prosecution history shows a single non‑final action and an abandonment notice, with no further maintenance or enforcement activity recorded. Because the mark is dead and no enforcement actions appear, the risk for a new, unrelated use is low, but a similar device in the same field could still be problematic.

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.
