Legal analysis: There is no limit to the number of applicants and inventors for a patent application. According to the principle of "the law can be done without prohibition", there is no limit on the number of applicants. But the position of the first inventor is the most important, and the second and third are of certain significance. The latter is only the meaning of nominally participating in the project. In addition, the number of applicants will also affect the application fee. If one person applies, the application fee will be reduced by 85%, and if two or more people apply, it will be reduced by 70%.
Legal basis: Article 16 of the Patent Law of People's Republic of China (PRC), an inventor or designer has the right to state in the patent documents that he is an inventor or designer.
The patentee has the right to indicate the patent mark on his patented product or the packaging of the product.
