The U.S. Patent and Trademark Office, in conjunction with the Smithsonian, has expanded a special display of his patents with materials from the National Museum of American History. “The Patents and Trademarks of Steve Jobs: Art and Technology that Changed the World,” opens May 11 in the S. Dillon Ripley Center.

The exhibit, designed and created by the National Inventors Hall of Fame and Museum, is a series of 30 4-by-8-foot panels designed to look like iPhones.

The American History museum has added a 1985 Apple Macintosh computer with mouse and keyboard and a 2010 Apple iPod.

As part of the programming, Smithsonian Secretary G. Wayne Clough will interview Walter Isaacson, author of the best-seller “Steve Jobs” on June 6 at Baird Auditorium, National Museum of Natural History. That event is sponsored by Smithsonian Associates.
