Can the "invention patent generating main business income" become an outsourced patent under the condition of listing in science and technology innovation board?

There are no restrictions on the source of invention patents, whether they are formed by independent innovation or obtained through patent purchase, but there are requirements for the transformation of invention patents. The technical scheme or product requiring invention patent must be transformed into sold products or services, and it is the main source of income for enterprises. This requires explaining the correlation between the invention patent and the main business income, as well as income certificates, such as contracts, sales receipts, invoices, etc.
