Opting for an Illinois state trademark is a cheaper alternative to a federal registration usually chosen by companies operating solely within the state’s borders. Here’s how it works:
Make sure your desired trademark is available by searching the Secretary of State’s online service
Fill out the State of Illinois Trademark or Service Mark Application
Pay the application fee
During the process, you’ll be asked for these details:
A list of products or services the mark will cover
An explanation of how the mark will be used, like in a marketing campaign
An example of how the mark looks with an illustration and sample of its use
