An incredible collection of blueprints that reveal the true genius of Apple founder Steve Jobs has gone on display.
More than 300 patients lodged by Mr Jobs throughout his life are being showcased in an exhibition sponsored by the U.S. Patent and Trademark Office in Virginia.
Some of them - such as the infamous iMac 'hockey puck' mouse - were duds, but some of them went on to be worldwide hits.
Steve Jobs famously helped create the first Apple computer, the Macintosh, the iMac, the iPod, the iPhone and the iPad.
David Kappos, director of the Patent and Trademark Office, said: 'This exhibit commemorates the far-reaching impact of Steve Jobs' entrepreneurship and innovation on our daily lives.
'His patents and trademarks provide a striking example of the importance intellectual property plays in the global marketplace.'
The exhibition is being put on by the non-profit organisation Invent Now and runs at the National Inventors Hall of Fame and Museum in Alexandria.
The free tribute opened earlier this month, and runs until January 15. – Daily Mail
