IBM had their ThinkPad laptops line until 2005. They sold it off, the entire PC business, which was a part of IBM, to Lenovo, a Chinese company. Lenovo bought the laptop designs, the tech, all, except the IBM name, obviously.

I never mentioned anything about employees, but if you know anything about how manufacturing companies with production lines work, well, then you’ll know how all assets, including employees with their know-how and experience, are transferred to the new company when sold. Whether they remain with time is another matter.

I do know what I am talking about.
