Why Geely can't get technology when it buys Volvo?

In order to protect its original car-making patents and technologies, Volvo proposed before Geely acquired Volvo that it could only be acquired by Geely Holding, not directly by Geely Automobile. Because some of Volvo's patents were jointly completed with Ford, they have the right to use them together, and some technologies belong to Ford. If Volvo needs them, it can continue to use them, but Geely cannot use them. Geely just bought a stake in Volvo. But if it is a joint venture, patented technology can be used. Therefore, Geely and Volvo jointly built a joint venture brand called Lectra, with technical support from Volvo and financial support from Geely, so that Geely can better learn from Volvo's advanced technology and build its own engine.
