OPENSYDE
Serial 79326624 · Principal Register

Owner: Sensor-Technik Wiedemann GmbH
Class 009 - Electrical & Scientific Apparatus
Class 042 - Scientific & Technology Services
Filed Jul 22, 2021
Registered Nov 14, 2023

The record shows that OPENSYDE is a live, Principal Register trademark owned by Sensor‑Technik Wiedemann GmbH, a German GmbH, and it was registered on November 14 2023 after filing on July 22 2021; the most recent meaningful event is the final disposition notice processed on February 14 2024 confirming the registration. The protection covers downloadable computer software for time‑ and cost‑saving implementation, commissioning, and analysis of control systems for mobile machinery (Class 009) and the design and development of computer hardware and software for the same purpose (Class 042). A similar name would raise the closest concern if used for software, hardware, or related services that deal with control‑system implementation for mobile machinery, because those are the exact goods and services listed. The record does not give the owner control over every possible use of the word “OPENSYDE” in unrelated fields. No opposition, cancellation, or other enforcement activity appears in the supplied history. I'd treat this as a meaningful concern if you plan a name in the same technical space.

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.

Your name deserves a straight answer.
