Yeah you have too do exactly that. The combinations your competitor has, are the combinations your customers will initially be looking for.
There are some trademark names out there like Domino’s Pizza’s Extravaganza! I use the name the “ULTIMATE” to replace it.
But for the most part All Traditional Combinations have the same names, and can’t be trademarked, like I have the Deluxe, a Hawaiian, a Vegetarian, a Cheeseburger Pizza, a All meat, the Reuben Pizza, the Margherita, the Garlic Chicken, and the BBQ Chicken.
But there are some combinations that are not so traditional, that you might wanna make up a new name for just in case.
