WILTHERVASerial 90817123 · Principal Register
Dead · Refused
Owner: SLSG Limited LLC
Class 005 - Pharmaceuticals
Filed Jul 08, 2021
The record shows that the WILTHERVA application is dead – it was abandoned on August 11 2025 because the owner never filed a required Statement of Use after the Notice of Allowance, and the USPTO sent an abandonment notice that same day. The owner listed is SLSG Limited LLC, a Delaware limited‑liability company. The only goods covered are in International Class 005: “Vaccines; cancer vaccines; pharmaceutical preparations for the treatment and prevention of cancer.” A similar name used for anything in that pharmaceutical space would be the closest record‑based concern, while uses in unrelated categories would be farther from the scope shown here. The record does not give the owner control over every possible use of the word WILTHERVA. This was a standard Principal Register filing; the prosecution history simply tracks the series of extensions the applicant requested before ultimately abandoning the mark. No oppositions, cancellations or court actions appear in the supplied history. I'd treat this as a meaningful concern if you plan a name in the same vaccine or cancer‑treatment field.
Full event history, owner details, and verdict inside.
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.
