How can patented technology obtain venture capital?

Generally speaking, patent holders need to complete a detailed business plan first, then use it to find venture capital institutions, and gradually modify and improve the business plan based on the feedback from the venture capital institutions. Then search again until you find it. But maybe the organization is not very interested in patented technology. At this time, it can first look for entity companies in the upstream and downstream of patented products, and the effect may be better.
