How long does something have to exist before it becomes public domain?
Excuse me, but I'm curious to understand the intricacies of intellectual property law when it comes to the concept of public domain. Could you elaborate on the duration required for an item, let's say a work of art or a piece of software, to attain the status of public domain? Is there a set timeframe that universally applies, or does it vary depending on factors such as the nature of the work, the jurisdiction in question, or any other specific conditions? I'm seeking clarity on the general principles and any nuances that might influence this determination.
