There are a lot of people and organizations (including those who should know better), that are “re-inventing” things over and over again. Re-invention is not bad in itself, as it rarely results in exactly the same concepts, but in an age when information from around the world and going back hundreds of years (including easily searched prior patents) are available at the touch of a button, there is NO excuse for POOR SCHOLARSHIP, unless one wants to be able to deliberately claim ignorance (something I would not want to brag about)or be able to make believable (but fake)claims of originally, in the hopes of duping people and organizations into giving them kudos they may not really deserve. I can’t understand how that we now all have available these tremendous prior-art research capabilities, people seem to still claim “I didn’t know that!” or “How could I have known”. In my opinion there is no researcher in the world who can use this as a legitimate or believable excuse any longer. In my opinion, the reason such oversights happen is due to either arrogance (i.e. ‘nobody else could have possibly come up with this idea’), laziness (i.e ‘I don’t have time for background research’), or just plain ego (i.e. ‘I don’t care what anybody else has done, I want to get the attention and rewards’).
