Patent and design protection distinguished
3.31.
The difference between patent law and the law of designs is, broadly, that the law of designs protects outward appearance or shape, whereas a patent protects an invention
or the underlying function or idea.

3.32.
The distinction becomes blurred because sometimes the shape of an object is essential for the object to perform in an intended way. In such a case it is said that shape is "dictated" by function, and the law in the United Kingdom and Hong Kong denies design law protection to such objects. In some cases a patent will protect the appearance of an object; for example where the appearance of an object can be achieved only by the application of a patented process. Paragraphs 11.17 to 11.25 discuss design protection.
