What this record means
The record shows that EVOTONE is an abandoned application, filed by Soundspring Audio, Inc. (a California corporation) and listed on the Principal Register, with the abandonment dated May 16 2016 because no Statement of Use or timely extension was filed after the Notice of Allowance. The only goods covered are “Consumer and professional electronic components, namely, integrated Digital‑to‑Analog Converters and amplifiers” in International Class 009, so a similar name used for those kinds of electronic parts would raise the closest record‑based concern, while uses in unrelated fields fall farther from the scope shown here. The record does not give Soundspring Audio control over every possible use of the word EVOTONE. The prosecution history shows a series of extensions of time to file a Statement of Use, but ultimately none was submitted, leading to abandonment. The latest meaningful event is the abandonment notice on May 16 2016, and no opposition or cancellation actions appear in the file. I'd treat this as a moderate concern if you plan to market digital‑to‑analog converters or amplifiers under a similar name.
