What is the type of software that has no intellectual property protections?

Shareware is a type of software that is distributed for free on a trial basis, but it typically requires payment for continued use or access to additional features. While users can try shareware without immediate payment, it is still under copyright protection and has specific usage restrictions.

Closed-source software is proprietary and protected by copyright laws, meaning that the source code is not made available to the public. Users must obtain permission from the owner to use, modify, or distribute it. This category of software explicitly includes intellectual property protections, contrasting with public domain software.

Freeware is software that is available for use at no cost, but it is still protected by copyright. Users can typically use and distribute freeware freely, but they cannot modify it or claim ownership. Thus, freeware retains intellectual property protections, differentiating it from public domain software.
