Why it matters

The window is 30 days. Most owners never hear about it.

App developers

Someone files a name one letter off yours in class 9 — software. It shows up in the Gazette, and the 30-day window starts whether you saw it or not.

Amazon sellers

A new application lands in your product class with a mark that sounds like yours. You find out when the window is open, not months after it closed.

Shopify & DTC brands

A lookalike filing for the same goods you sell. We send one email with what matched, why, and the date the window closes.

How it works

Spotsworth reads every filing

Each day's new applications and each Tuesday's Gazette are compared against your mark — spelling, sound and shared words.

You get the deadline

Anything close lands in your inbox with how it resembles yours and when the opposition window closes.
