While you can trademark your business on your own, don’t hesitate in reaching out for help. You always hire professional or legal services to help you with this.
You can also go to the trademark office. Registration of trademarks online can be easier to do, but sometimes you may need someone to walk you through it physically.
Once you have a trademark in place and based on how you’re scaling your business, remember to get a trademark attorney. This will help you get to know the trademark law better and if/how your exclusive rights change over time.
Note: There is also something called an “unregistered trademark”. The common law trademark is an enforceable mark created by a business, individual or brand to signify or distinguish a product or service and define its uniqueness. It is legally different from a registered trademark.
