What this record means
The record shows that DIAGONALLY‑STRUNG is an abandoned application, filed by PowerAngle LLC, a New York limited liability company, and its status was set to abandoned on June 8 2015 after the applicant failed to respond to an Office action. The only goods listed are “rackets for tennis, squash, badminton and racquetball” in International Class 028, so a similar name used for sports equipment of that type would raise the closest record‑based concern. The record does not give PowerAngle control over the wording in other categories such as clothing, software or services, and it does not extend to unrelated products. The prosecution history shows a non‑final action issued in November 2014 followed by an abandonment notice in June 2015, after which no further filings occurred. No oppositions, cancellations or court actions appear in the supplied history. I'd treat this as a modest concern if you plan to brand racquet‑type gear with a comparable name.
