Quizplus · Accepted Answer

According to the public use doctrine, if an invention has been in public use for more than one year before an application for a patent is filed, the patent will not be granted. This is to ensure that the inventor does not have an unfair advantage over the public and that the invention has not already become part of the public domain. Choice B is incorrect because an invention can be used in the public domain before being granted a patent, but it cannot be sold or offered for sale. Choice C is incorrect because the inventor does not have to test the invention in the public domain for validity. Choice D is incorrect because the invention may still be protected under patent law during its term period.
