Felix has designed a pair of sunglasses that can be folded and put into a case that easily fits into a shirt or pant pocket. Felix wants to know if he can receive a patent on this invention. Which of the following responses would be most accurate according to the U. S. patent law?

He cannot receive a patent since he is merely making the sunglasses more portable.

Explanation: Patent refers to the right granted to the inventor of a product, machine or equipment such that others are excluded from making, using, selling or importing such product which is adapted for use of the patent.

Felix cannot receive a patent on his invention because he only made a portable version of a preexisting invention. Patents are granted to products which are new, useful and non-obvious.
