Federal (USPTO) — start here
A federal registration, filed once through the USPTO, gives nationwide rights that include Illinois. It’s the right starting point for almost any business selling across state lines, online, or planning to expand beyond Illinois.
Illinois state registration
Illinois’s state trademark register is run by the Secretary of State — Business Services Department. The published filing fee is $10 per class, with registrations renewing every 5 years. It only protects a mark within Illinois’s borders, not nationwide — always confirm the current process and fee on the agency’s own page before filing.
When does a Illinois state trademark make sense?
- Your business genuinely operates only within Illinois — a local shop, restaurant or service business with no plans to sell out of state or online.
- You want fast, low-cost protection now while a federal intent-to-use application is still pending.
- You need to establish Illinois-specific priority for a name ahead of local competitors.
For most brands — especially anything sold online, as software, or shipped across state lines — federal registration is the stronger, more durable choice, and a Illinois filing (if used at all) is a complement to it rather than a substitute.
