DRAFT - NOT LEGAL ADVICE
Re: USPTO trademark application Serial No. 00000000 ("SONBURST"), filed 2026-01-13.
To Whom It May Concern: I am the owner of the mark "SUNBURST". MarkSentry's automated triage judged the referenced application a high-severity conflict with my mark, for the following reason: SONBURST differs from SUNBURST by one vowel and is phonetically near-identical.. Mark owners have 30 days from the application's publication for opposition to file a Notice of Opposition with the USPTO's Trademark Trial and Appeal Board, and I intend to evaluate opposing Serial No. 00000000 within that window.
