What is the purpose in this day and age of information abundance? I believe the whole reason patents were invented was because there was no way to search for and verify originality of ideas, since it was pre-internet and google etc. Nowadays you can google similar products or ideas to yours and get a comprehensive list. If say for example an inventor posts his invention on a public repository like facebook, can that not serve as a valid way of verifying that the poster is the original inventor of the idea? After all posts on facebook, for rxample, are timestamped and facebook is a reputable, reliable source of information, is it not?
My thinking is it is no longer necessary to file a patent when you can prove originality of an idea from online sources. Any thoughts?
