Following news that Apple has applied for a patent for the technology behind the workings of the iPod and its user interface, details have emerged about Jeffrey Robbin and Timothy Wasko, the inventors listed beside Steve Jobs on the patent application.

According to Cnet, Robbin was the primary author of SoundJam, the MP3 player to which Apple bought the rights in early 2000 "as it sought to make up for lost ground in digital music after it underestimated demand for CD-RW drives". Robbin moved to Apple with the acquisition and later took a lead role on the company's iTunes music download service.

Wasko worked with Jobs at Next before moving back to Apple after Jobs took up the post of interim CEO (and later CEO).
