For example I want to create/develop new booking.com
All the options from booking.com will be used on this one.
I don't plan to steal the code or design, I will code and design it from scratch myself. No images/text etc will be taken from competitor.
What concerns me are the options (tools) that give property owners to input all information about their properties. Those will be identical as competitors, and without it the website would not have purpose.
Are the websites like booking and similar under some kind of copyright/intellectual property law?
