Patent utilization mainly includes five aspects: patent industrialization, patent commercialization, patent financialization, patent competitive utilization and patent information utilization. Patent industrialization refers to the act of applying patented technical solutions to industrial reality and transforming them into real productivity. Patent industrialization includes both self-implementation of patents and implementation by others after licensing, trading, and transfer. For actors, industrialization in any form can bring about improvements in social production efficiency, so the benefits realized are direct benefits.
