TDOTSerial 98104937 · Principal Register
Dead · Refused
Owner: Littelfuse, Inc.
Class 009 - Electrical & Scientific Apparatus
Filed Jul 27, 2023
The record shows that the TDOT application filed by Littelfuse, Inc., a Delaware corporation, is now dead; it was abandoned on November 24 2025 because no Statement of Use was filed after the Notice of Allowance was issued. The only goods listed are “thermal sensing device, namely, sensors for measuring temperature, for use in electronics and circuit protection devices; temperature sensors; circuit over‑temperature protector devices” in International Class 009, so a similar mark would raise the closest concern for products that sense or protect temperature in electronic equipment. The record does not give Littelfuse control over every use of the word “TDOT” in unrelated fields. Because the application never reached registration, there is no supplemental‑register issue to explain. The latest meaningful event is the abandonment notice on November 24 2025, and the supplied history shows no oppositions, cancellations or other enforcement activity. I'd treat this as a modest concern if you plan a name for temperature‑related electronic components.
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.
