Since you haven’t made any sales yet, you should file your trademark under “intent to use” rather than “in use.” The “intent to use” option is for businesses that have a genuine plan to use the trademark in commerce but have not yet started making sales. Once you start selling, you will need to submit a Statement of Use to convert the application into a fully registered trademark. If you were already making sales with the brand name displayed on the product or packaging and could provide proof, you could file under “in use,” but since no sales have been made, the “intent to use” option is the correct choice.
If your product is already listed with your brand name and properly branded packaging, you may qualify for ‘In Use’ when filing your trademark. However, if you haven’t made any sales yet, ‘Intent to Use’ might be safer to avoid complications. Once you get sales, you can later file a Statement of Use. I know someone who is experienced with trademark filings, I can recommend if you need his help on that.
Since you haven’t made any sales yet, you’ll want to file under “Intent to Use” rather than “In Use.” The latter requires proof that you’re already selling products under your brand name. Once your trademark is approved and you’ve made sales, you can submit a Statement of Use to finalize it.
