Legal Analysis: Useful. The benefits obtained are also second only to those of the first inventor. Because in addition to receiving some government bonuses, patent inventors can also be used to evaluate professional titles. When evaluating professional titles, the evaluation is based on different levels and even different units. However, the requirements for patents are not necessarily the same. For example, for some high-level professional title evaluations, if the first inventor of the patent is required, the second inventor is basically useless. Therefore, whether the second inventor of a patent is useful depends on the specific professional title evaluation requirements.
