Software can be both patented and copyrighted. Patents protect the functionality and design of the software, while copyrights protect the expression of the software code.
Software is typically protected by copyright, which gives the creator exclusive rights to control how the software is used, distributed, and reproduced. Patents, on the other hand, protect inventions and processes, but they can also be used to protect certain aspects of software, such as unique algorithms or methods.
Copyrighted software that is distributed free for a trial period is commonly referred to as "trialware" or "shareware." This type of software allows users to evaluate its features and functionality before deciding to purchase a full version. During the trial period, users may have access to all or limited features, after which they are typically required to pay for continued use. This model helps developers promote their products while still protecting their intellectual property rights.
