What this record means
The record shows that the mark STAINORAIN was abandoned on June 12, 1991 after the applicant, E. I. du Pont de Nemours and Company, filed an express abandonment, so it is not a live or pending registration. Because the filing contains no listed classes or goods‑and‑services descriptions, the USPTO record does not reveal any specific commercial scope, meaning a similar name would only raise a concern where a later filer claims the same wording for the same undefined goods or services. The record does not give the owner control over every use of the word “STAINORAIN.” The prosecution history shows a notice of unresponsive amendment in early March 1991 and a non‑final action in November 1990, but no supplemental‑register filing appears. The latest meaningful event is the express abandonment in June 1991, and the supplied history shows no oppositions, cancellations or court actions. I'd treat this as a modest concern if you plan to use the same wording in a comparable market.
