Thanks to Danielle from PBS for sending in this interesting video about The First Software Patent. They will be releasing a new video every 2 weeks, check out the channel for a bunch of interesting ones they have already released (there are 6 so far). The guy who invented the screw in coffin might not get rich from the idea but if this was available when the idea of burring our loved ones who passed away came to be I think it would have been adopted. It is simple to install, takes up a minimal amount of room and is simple to relocate if needed.
