How to Register a Trademark in Idaho (2026)
Reviewed by DocDraft Legal Team · Idaho · Last updated August 12, 2026
Trademark rights are mainly federal, but Idaho businesses that operate only inside the Gem State can register a mark with the Idaho Secretary of State under Idaho's trademark statute, Idaho Code 48-501 et seq. An Idaho registration protects the mark within Idaho, must reflect a mark already in use in the state, and runs for ten years before it needs renewal. The Secretary of State handles filings through its SOSBiz online portal. State registration is cheaper than a federal USPTO filing but gives no rights outside Idaho.
How do I register a trademark in Idaho?
File an Application for Trademark or Service Mark Registration with the Idaho Secretary of State, along with a specimen showing the mark in actual use in Idaho and the per-class fee. Idaho requires the mark to already be in use in the state before you apply. Filings go through the SOSBiz online portal at sosbiz.idaho.gov.
How much does an Idaho state trademark registration cost?
The Idaho Secretary of State charges roughly $30 per class code to register a trademark or service mark. Filing on paper rather than online typically adds a $20 manual processing surcharge. Verify the current amounts on the SOSBiz portal, since the state can adjust its fee schedule under Idaho Code 48-517.
How long does an Idaho trademark registration last?
An Idaho state trademark or service mark registration lasts ten years from the date of registration and can be renewed for successive ten-year terms as long as the mark stays in use. You renew through the Idaho Secretary of State near the end of each term. Renewal duration and procedure are set by Idaho Code 48-506.
Does an Idaho registration protect my mark outside Idaho?
No. An Idaho Secretary of State registration only gives rights inside Idaho. To secure nationwide priority and the ability to use the federal registration symbol, you must register with the USPTO under the Lanham Act. Many Idaho owners use a state filing for local protection and file federally once they sell across state lines.
Idaho registration is use-based and channeled through SOSBiz
Idaho's trademark statute sits in Title 48 of the Idaho Code, Chapter 5 (Registration and Protection of Trademarks), beginning at Idaho Code 48-501, and it is administered by the Business Services Division of the Idaho Secretary of State in Boise. Unlike an intent-to-use federal application, Idaho will not register a mark that is not yet in use. The applicant must already be using the mark in the ordinary course of business within Idaho and must submit a specimen, such as a label, brochure, business card, or website capture, proving that use. Applications are filed electronically through the state's SOSBiz portal, which replaced older paper-first workflows and lets filers avoid the manual processing surcharge that applies to mailed forms. Fees are set per class code under Idaho Code 48-517, and the registration runs for a ten-year term that is renewable under Idaho Code 48-506. Because Idaho protection stops at the state line, the office itself notes that registering in Idaho provides protection rights within the state only.

Regional Variances
Idaho state registration vs. federal vs. common law
Idaho (Secretary of State, Idaho Code 48-501 et seq.)
Use-based registration filed through SOSBiz. Roughly $30 per class code, ten-year renewable term under Idaho Code 48-506. Protects the mark within Idaho only; no intent-to-use option.
Federal (USPTO, Lanham Act)
Nationwide priority, presumption of ownership, the registered symbol, and federal-court enforcement. $350 per class; ten-year term, renewable. Allows intent-to-use filings that Idaho does not.
Common law (use alone)
Rights arise automatically from use in Idaho, limited to the actual trading area. Free, but hardest to enforce and no registration certificate or registered symbol.

Frequently Asked Questions
Yes. Idaho registers only marks that are already in use in the state, so you cannot reserve a mark you have not started using the way a federal intent-to-use application allows. You must submit a specimen, such as a label, brochure, or website capture, showing the mark used in the ordinary course of business in Idaho.
If your business is purely local to Idaho, a Secretary of State registration is cheaper and faster and protects the mark within Idaho. If you sell across state lines or online, a federal USPTO registration is the better choice because it gives nationwide priority, the right to use the registered symbol, and federal-court enforcement. Many owners eventually do both.
Yes. Idaho adopted the Uniform Trade Secrets Act as the Idaho Trade Secrets Act, codified at Idaho Code 48-801 et seq. It lets a business sue for misappropriation of confidential information that has independent economic value and is kept secret through reasonable efforts, with remedies including injunctions and damages. This protects know-how that trademark law does not cover.
Idaho has no dedicated right-of-publicity statute, and no published Idaho case has clearly established a common-law right of publicity. Idaho does recognize privacy torts, which can include appropriation of a person's name or likeness. Anyone relying on name or likeness rights in Idaho should treat the area as unsettled.: confirm current Idaho case law on publicity.
If you do not renew before the ten-year term ends, the Idaho registration expires and you lose the statutory benefits of registration in the state. You may still hold common-law rights from continued use, but those are limited to the area where you actually operate. Renewing on time through the Secretary of State keeps the stronger registered protection intact.
