Although item A is a new mouse developed in spare time, the research and development of computer mouse belongs to Wang's work task, so it should belong to the service invention, and the patent application right should belong to the unit, so item A is correct.
in item b, even if Wang didn't use the material and technical conditions of company A to develop a new mouse, it still belongs to the invention completed by the unit, which should be a service invention, and the patent application right still belongs to the unit rather than the individual, so item b is wrong.
in item c, Wang mainly developed a new type of mobile phone by using the material and technical conditions of the company, which is still a service invention, and the patent application right should still belong to the company rather than the individual, so item c is wrong.
In item D, if Wang went to Company B to develop a new mouse within one year after his resignation, the new mouse still belongs to the service invention of the original company, and the patent application right should belong to the original company A rather than the new company B, so item D is wrong.
