ĭEC maintained the original and primary IP rights to the software in every version produced. Mentec, when it acquired the rights to the PDP-11 software (there were some that it didn't get) acquired what might be best described as 'limited rights'.Īs I understand it, and remember that where the following says DEC, for example, DEC's rights are passed by succession to Compaq and then to HP, the rights went like this. Ahh the old question of ownership of the PDP-11 OS's strikes again!
