Just a short while ago, I remember another clock issue on the docket. Apple in U.S. District Court showed the jury how Samsung's clock icon resembled its iPhone icon. That was like a slowly tightening noose around Samsung's neck. Any member of the jury could see the similarity between the two. The noose was tightened further when Apple illustrated how Samsung had used the handset phone image once found on AT&T phone booths. Apple used it first; Samsung shouldn't have copied.

Still, it all seemed a little confusing. AT&T originated the image but Apple was suing Samsung because its phone icon looked too much like Apple's. I set about researching this issue, trying to clear up when Apple's elevated design sense allowed it to engage in copying, while copying by others was of the guilty kind. The jury had figured this out. Why couldn't I?

It wasn't easy. As you comb through Walter Isaacson's biography of Steve Jobs, you come across instance after instance where Jobs picked up a good idea from someone else and copied it. Often times, he fit a good design idea into an Apple product that became a commercial success, something that the originators of the idea might have failed to do.

The ideas were sometimes just someone else's design details. For example, Jobs was fond of the leather stitching found in his Gulfstream jet, and he insisted an identical pattern be used as the faux stitching portrayed in the iCal calendar application. But sometimes this process of making a commercial success out of someone else's idea got confused with originating the idea itself. In that case, Apple not only collected the profits on the product but asserted ownership of the ideas as well.

Xerox Parc, for example, produced a breakthrough set of ideas for a new user interface, based on using graphical elements powered by a user's mouse. Jobs toured Parc and became excited by the UI's prospects. Later, a team of Apple engineers toured the facility and came away just as enthusiastic. They went on to produce the Macintosh user interface based on visual elements, powered by a mouse.

At the time, Microsoft was producing software for Apple, and Jobs and Bill Gates had struck a deal where Microsoft would produce software for the Mac and leave Apple a year's lead time, before bringing windowing software out for the IBM PC. But the Mac was late and the year was nearly up when the Mac finally launched. Soon, Microsoft Windows was available in the market as well, and Jobs took offense that Microsoft dared to produce a competitor, although Gates had lived up to their agreed timetable.

Furious, Jobs summoned him to Cupertino and confronted him in his conference room, "surrounded by 10 Apple employees eager to watch their boss assail him," according to Jobs' biographer, Isaacson. It was during the period when Jobs was known for his volcanic temper. "You're ripping us off," he shouted. "I trusted you, and now you're stealing from us," Jobs said. Thirty years later, he would still tell Isaacson, "They ripped us off completely because Gates has no shame."

But Gates knew where the graphical user interface had originated. With Apple employees looking on, he advised Jobs: "I think it's more like we had this rich neighbor named Xerox and I broke into his house to steal the TV set and found out that you already stolen it."

So did Apple copy the Swiss Railroad clock or didn't it? During the trial, Apple didn't accept Samsung's explanation that internationally recognized symbols, such as the Ma Bell phone, make good user icons and should be available to all. But Apple has been caught doing something similar, recognizing a useful icon in a design that it now concedes belongs to the Swiss Federal Railway. The amount of payment wasn't disclosed. But I hope it was more than a slap on the wrist.
