Zakaj tehnološki patenti prihajajo do uresničitve po 20ih letih, programski pa dosti prej?

As you might imagine, waiting 20 years is a pretty nasty chore,” said Weinstein, an emeritus professor at the University of Houston.

The time delay between when a software patent application is filed, and when it becomes public is 18 months.[6] This is a compromise position allowing U.S. innovators to develop their software before revealing details about it and giving competitors an unfair look at their research and development, and providing the public notice within a fair amount of time to allow others to develop their own technology.
