What this record means
The record shows the mark ELSA is dead – it was abandoned on Jan 9 2017 because the applicant never filed a Statement of Use after the Notice of Allowance, and the history contains no later activity; the owner listed is THE BABCOCK & WILCOX COMPANY, a Delaware corporation. The registration covered only “engineering and engineering consulting services relating to the control and monitoring of an air‑quality‑control‑system (AQCS) train, including controlling and monitoring the cost of the system reagents and power usage … for use in connection with power‑generating units” in International Class 042, so a similar name used in that technical consulting niche would present the closest record‑based concern. The record does not give the owner control over every use of the word ELSA in other industries or contexts. Because the application was on the Principal Register and never moved to the Supplemental Register, there is no supplemental‑register sequence to note. The latest meaningful event is the abandonment notice mailed on Jan 9 2017, and the supplied history shows no oppositions, cancellations or other enforcement actions. I'd treat this as a modest concern if you plan to offer engineering‑consulting services for air‑quality control systems, but the risk is far lower for unrelated goods or services.
