According to Article 23 of China's Regulations on the Administration of Enterprise Name Registration, the enterprise name can be transferred together with the enterprise or a part of the enterprise.

The enterprise name can only be transferred to one enterprise. The transferor and transferee of the enterprise name shall sign a written contract or agreement and report it to the original registration authority for approval.

After the enterprise name is transferred, the transferor shall not continue to use the transferred enterprise name.

Therefore, if Sony (the parent company) is willing to transfer the names of its subsidiaries together, it is not prohibited by law.

However, even if Sony (the parent company) agrees to the transfer, and the transferee company has market confusion in the process of actually using the name in the market, the industrial and commercial authorities can still investigate and deal with it according to the third paragraph of Article 5 of the Anti-Unfair Competition Law. This is to protect the legitimate rights and interests of consumers. At the same time, the industrial and commercial authorities can also identify inappropriate enterprise names ex officio and correct them.

Second, about trademarks.

Trademark and enterprise name are independent intellectual property rights respectively. No one may use the same or similar trademark as the registered trademark of Sony on the same or similar goods unless approved by the trademark holder of Sony. In addition, according to Article 13 of the Trademark Law, if the Sony trademark is recognized as a well-known trademark, even if it is used on different and dissimilar goods, causing market confusion, it is prohibited to use it.
