DOUBLE BLACK DIAMONDSerial 90738326 · Principal Register
Dead · Refused
Owner: 705 Cambridge Inc.
Class 001 -
Filed
The record shows that the application for “DOUBLE BLACK DIAMOND” is dead, having been refused and dismissed on Feb 14, 2022 because the filing date did not meet the minimum requirement, and the owner listed is 705 Cambridge Inc., a Delaware corporation. The goods are limited to a masterbatch additive modifier used in polymer or material formulations, described as a wet or dry suspension containing graphene, carbon nanotubes and other proprietary ingredients that alter thermal, electrical, friction and mechanical properties. A similar name would raise the closest concern only for products that function as chemical or structural modifiers in the same class 001 context; uses in unrelated fields such as apparel, software or services would be farther from the scope shown. The record does not give the owner control over every possible use of the words “double black diamond.” No supplemental‑register filing appears, and the prosecution history simply notes examiner assignment and data entry before the refusal. The latest meaningful event is the status date of Feb 14, 2022, and the supplied history shows no oppositions, cancellations or other enforcement activity. I'd treat this as a meaningful concern if you plan a comparable additive product, but the risk drops sharply for dissimilar goods.
Full event history, owner details, and verdict inside.
The way I'd use it, honestly, is as the thing you attach when a bank, a marketplace, or a co-founder asks "are we clear on the name". It answers in one page.
