CROSSFLOWX

What this record means

The record shows that CROSSFLOWX is a cancelled Principal Register service mark owned by Heidi Kristoffer, LLC; the registration was cancelled on September 11 2026 because the owner failed to file an acceptable Section 8 declaration. The mark was limited to class 041 services—specifically “providing fitness instruction services in the field of yoga, core strength training and cardio.” A similar name used for fitness‑related instruction would be the closest area of concern, while uses in unrelated fields such as software or apparel fall farther from the scope shown in the record. The cancellation means the USPTO record no longer grants any exclusive rights, but it does not mean the wording is free for all purposes. The latest meaningful event is the notice of cancellation and the Section 8 cancellation entry on September 11 2026; no opposition, cancellation proceeding, or other enforcement action appears in the history. I'd treat this as a moderate concern if you plan a fitness‑service brand that resembles CROSSFLOWX, but the risk drops sharply for dissimilar goods or services.
