What distinguishes Public domain technology?

Public domain technology is defined as a method, idea, or innovation that is available for use by anyone without any patent restrictions. This means that individuals or organizations can use, modify, and distribute the technology freely without the need for permission or payment of licensing fees. In contrast to technologies that are protected by patents, which require licenses and are subject to legal restrictions, public domain technology encourages open access and collaboration. This characteristic makes it particularly valuable for research, development, and innovation, as it removes barriers to entry and allows for widespread use and enhancement by anyone interested in leveraging those technologies.
