The investment firm which bought the Vaio brand from Sony earlier in 2014 is reportedly planning to launch a new range of smartphones under the name.
According to the report, the Japanese Industrial Partners group plans to launch the devices in partnership with a Japanese mobile network.
The phones, running on the Android OS, would likely compete with Sony in its own backyard. It seems unlikely they would emerge beyond Japan at this stage.
Sony itself is seemingly planning a host of mobile launches for CES with new flagship smartphones and tablets running the Android 5.0 Lollipop operating system out of the box.
The most noteworthy releases were the Vaio Fit and Vaio Pro laptops in June. They arrived without Sony branding but were otherwise identical to those previously on sale.
Since leaving the computing business, Sony has increasingly focused on mobile and gaming and is heavily relying on the PS4 to spearhead a return to form in 2015.
