- A sample row links KLARITY to CLARITY in class 003 and shows serial number 50008897, publication date, and initial window close.
Field notes
The watch checks both new applications and marks published for opposition, using spelling and sound similarity within the same or coordinated classes. Its sample row includes a USPTO serial number and TSDR link; the displayed deadline is only the initial 30-day window, since extensions are possible. The stated scope is US federal records, not international filings.
