What this record means
The record shows that the application for HYGIENIST CLEAN (Serial 86400450) was abandoned on August 21, 2015, after the applicant, Global Tonic LLC, failed to respond to an Office action, so the mark is not live or registered. The only goods listed are “oral cleanser, namely, oral rinse” in International Class 3, meaning the closest area of concern would be any other oral rinse or similar oral hygiene product that uses the same wording. The record does not give Global Tonic LLC control over every use of the words “hygienist” or “clean” in unrelated categories. Because the application never reached registration, there is no Supplemental Register entry or related examination sequence to note. The latest meaningful event is the abandonment notice dated August 21, 2015, and the supplied history shows no oppositions, cancellations or other enforcement activity. I'd treat this as a modest concern if you plan a name for an oral rinse, but the risk drops sharply for products outside that narrow scope.
