What this record means
The record shows that “PERCY” is an abandoned application (status dead) that was filed by Maison Battat Inc., a Canadian corporation, and it never moved beyond the principal‑register filing; the USPTO issued a Notice of Allowance in July 2020 but the applicant failed to file a Statement of Use, leading to an abandonment notice and final abandonment on Feb 22 2021. The only goods listed are “Dolls and accessories therefor” in International Class 028, so the closest area of concern would be another mark using “Percy” for toys, dolls or related accessories. The record does not give the owner any control over the word “Percy” in unrelated categories such as clothing, food or services. The prosecution history contains no oppositions, cancellations or court actions, so the supplied history shows no enforcement activity. I'd treat this as a moderate concern if you plan a similar name for toys, but the risk drops sharply for dissimilar product lines.
