## History

Formerly known as OS/4, the product was renamed by Roberto J. Dohnert and the software team to Black Lab Linux after the USPTO denied his trademark application for OS/4.[11] PC/OpenSystems LLC had acquired the rights to the name Black Lab Linux in 2008 after the acquisition of Terrasoft Solutions by Fixstars.[12] In its current incarnation, Black Lab Linux does not share any code or platform similarities with Terrasoft Solutions's product called Black Lab Linux as Terrasoft Solutions's release was for the [PowerPC](/source/PowerPC) Processor. Fixstars Linux's products, Yellow Dog Linux and Y-HPC, are currently developed under the [Yellow Dog Linux](/source/Yellow_Dog_Linux) brand.[*[citation needed](https://en.wikipedia.org/wiki/Wikipedia:Citation_needed)*]

Upon the purchase of the [Linspire](/source/Linspire) intellectual properties from [Bridgeways, Inc.](/source/Xandros) in 2018, PC/OpenSystems LLC discontinued Black Lab Linux in favor of Linspire and [Freespire](/source/Freespire).
