Genie Effect
"The United States Patent and Trademark Office on Tuesday granted Apple Computer with a patent for an "ornamental design for a user interface for computer display."

Otherwise known to Mac OS X users as the "genie effect," the feature presents the illusion that application and Finder windows are shrinking into the system dock when minimized by the user.

The document credits the original design to Bas Ording, an interface developer who has endured a lengthy term at Apple working directly under the helm of Steve Jobs.

Apple filed for the patent in February of 2002, two years after the company first introduced Mac OS X and the Mac OS X Dock to the world."

I do not think Apple tradmarked the bouncing icon/loading icon with arrow underneath it yet. I think the Genie effect trademark applies to other companies/individuals who use it in their operating systems.
The ability to move over an image with your mouse and enlarge the image is not new. Javascript takes advantage of this function. It is just the sucking effect into and out of the dock that bring up the pages contents that is TM.
