The monetary contribution of the shareholders of the company shall not be less than 30% of the registered capital, unless the monetary contribution is only a patent, the highest proportion may reach 70%. Patent companies must be evaluated and priced by a third-party organization, and cannot be negotiated by shareholders. As for the shareholding ratio of the patent after pricing, it depends on your monetary contribution. In other words, if your patent appraisal price is 500,000 yuan, and it accounts for 40% of the equity (only the proportion of patents, not your total contribution), then you and another shareholder must contribute 750,000 yuan in cash.
If both parties want to determine the price and proportion of intellectual property rights through consultation, they can adopt the form of partnership. (But partners have a wider range of responsibilities than shareholders of the company. )
