Ha, ha, ha, ha, of course, believe it. Your work is very good. If there are already finished products and listed on the market, the company will definitely apply for patents.
The small one in the middle is for the sake of being depressed in appearance and having no sense of rhythm, for the sake of drying a sock or something in the middle, and for saving the cost of raw materials by doing so.
In other words, I really haven't applied for a patent alone... I feel a bit of a failure
My family has a basket of such patents.
Why is there one square missing in the middle?
