In-N-Out Burger Sues Start-Up Delivery Service

SACRAMENTO (CBS13) – It's heating up in the In-N-Out kitchen.

The San Jose Mercury News reports the fast food chain is filing a lawsuit against "DoorDash," claiming the start-up delivery service is violating trademark laws.

In-N-Out says DoorDash is delivering their food and using its logo on their website.

"DoorDash is using our food and trademarks in a way that implies we have some kind of partnership or agreement with them, when that is not the case," an In-N-Out lawyer said in a statement to San Jose Mercury News.

The burger chain says they want DoorDash to stop selling their food.

DoorDash has continued to deliver In-N-Out food despite the requests to stop.
