What's the difference between applying for a patent for circuit board appearance and applying for integrated circuit layout design?

Applying for an appearance patent is generally carried out when the product has obvious appearance characteristics and needs others not to look exactly like you. No one in a normal agent will apply for an appearance with a circuit board, which will not play a protective role. It is best to listen to the opinions of the intermediary when applying, and they will advise you what to apply for from a professional point of view.
