What this record means
The record shows that EVOTONE is an abandoned application – the USPTO marked it “dead” after the owner, SOUNDSPRING AUDIO, INC., failed to file a required Statement of Use, and the abandonment notice was issued on Dec 2 2019. The filing covered only one class, 009, describing “consumer and professional electronic components, namely, integrated Digital‑to‑Analog Converters and amplifiers,” so a similar name used for those kinds of electronic parts would be the closest area of concern. The record does not give the owner control over every use of the word EVOTONE in other industries or product categories. Because the mark was pursued on the Principal Register, there is no Supplemental Register sequence to note. The latest meaningful event in the file is the abandonment notice in December 2019, and the supplied history shows no oppositions, cancellations or other enforcement activity. I'd treat this as a moderate concern if you plan to brand electronic DACs or amplifiers with a similar name.
