I always understood the purpose of patents was to provide incentive to bring trade secrets out into the documented open for the long-term benefit of society by having a great body of knowledge that anyone can use. So understanding of great inventions didn't disappear with the inventor. A short-term exclusivity on using the technology was the way to provide renumeration for being willing to share your discoveries with the public.

Rubber band scrolling is a cute, even useful, discovery, but it seems like it could be duplicated by just about anyone without any knowledge of what would otherwise be trade secrets. Is that worth documenting for future generations in this way given the high social costs of taking such documentation?
