ECOSTONE

What this record means

The record shows that ECOSTONE is a live, Principal Register registration owned by Grace Digital, Inc., a California corporation, and it covers audio speakers and home‑theater systems comprising audio speakers in International Class 009; a similar name used for any kind of speaker or home‑theater equipment would raise the closest record‑based concern because the goods are listed very specifically. The record does not give Grace Digital control over every possible use of the word “ECOSTONE” in unrelated fields, so unrelated products would be farther from the scope shown here. The most recent meaningful event is the acceptance of a Section 8 declaration on Dec 1 2023, confirming the registration remains active. The prosecution history contains only routine filing, publication, registration and maintenance entries and shows no oppositions, cancellations or other enforcement actions, so the supplied history shows none. I'd treat this as a meaningful concern if you plan to market speakers or home‑theater gear under a similar name.
