Of Apple Patent US 7,479,949 and US 7,469,381 UC Berkeley, Center for Entrepreneurship and Technology IEOR 190G Patent

1. Palm Pre Invalidity Of Apple Patent US 7,479,949 and US 7,469,381 UC Berkeley, Center for Entrepreneurship and Technology IEOR 190G Patent Engineering Abhishek Gupta, BA CS Joshua Miller, BS ME

2. Touch Screen Technology • Touch Screen technology refers to using fingers to manipulate objects on a touch screen. • Achieved through variety of ways: • heat • finger pressure • infrared light • optic capture

3. Touch Screen Technology • For invalidity on the two patents, touch screen only refers to single touch methods on the Apple IPhone and Palm Pre. • This includes: • Flicking Left/Right • Locking the screen • Diagonal movements • Document edge in screen auto-display

4. Multi-Touch Tablet 1985 • Developed a touch tablet capable of sensing an arbitrary number of simultaneous touch inputs, reporting both location and degree of touch for each. • Developed by Bill Buxton at University of Toronto, the video clearly demonstrates multi-touch concepts of sliding finger across: http://www.billbuxton.com/touchTabletWindows.swf

5. Digital Desk 1991 • A manipulation of a desktop display • An early front projection tablet top system that used optical and acoustic techniques to sense fingers and objects • Clearly demonstrated touch concepts such as finger gestures or a finger flick • Demo video:  http://video.google.com/videoplay?docid=5772530828816089246

6. Starfire 1992 • A film produced which displayed the idea of pinching. Although nothing technology related was developed – the film, produced at Sun Microsystems, clearly envisioned the future to include ‘pinching’ and ‘diagonal movements’

7. FingerWorks 1999 • Founded by two University of Delaware academics, John Elias and Wayne Westerman • Product largely based on Westerman’s thesis:  Westerman, Wayne (1999). Hand Tracking,Finger Identification, and Chordic Manipulation on a Multi-Touch Surface. • The company was acquired in early 2005 by Apple, where Elias and Westerman moved to Apple.

8. FingerWorks 1999 “state C detects significant motion on all touching fingers and advances to the manipulation state M, the channel selection is locked in. Additional finger touchdowns or liftoffs will not affect the channel selection during manipulation unless they meet the special synchronization sequence” (pg. 269)

9. Portfolio Wall 1999 • Images placed on a wall, "to advance to the next slide in sequence, one flicked to the right. To go back to the previous image, one flicked left." • "The gestures were much richer than just left-right flicks. One could investigate different behaviors, depending on the direction you moved your finger." • "In this system there were eight options, corresponding to the 8 main points of a compass. For example, a downward gesture over a video meant 'stop'. A gesture up to the right enabled annotation, down to the right launched the application associated with the image, etc."

10. Portfolio Wall 1999 • The advancing from one slide to the next appears to read directly on claim clause of flipping through items in a list and is the same example as in the Apple Patent. • According to the video, the left/right flick can anticipate the horizontal and vertical IPhone locked scrolling. • Also show’s that other commands can be on the 8 other compass points. http://www.billbuxton.com/PW+Pda.swf

11. Diamond Touch 2001 • http://www.diamondspace.merl.com/bimanual.php • Developed by Mitsubishi Research Labs, a tabletop similar to Microsoft Surface that could adapt finger touches. Researchers published multiple papers about it. • Videos clearly demonstrate ability for finger to do vertical, horizontal, and diagonal movements which translate into actual actions • Both videos show that scrolling on the screen can occur with a manual finger touch http://www.diamondspace.merl.com/videos/2006_wu_gestures_lr.mov http://www.diamondspace.merl.com/videos/2006_tse_multimodal_gaming.wmv

12. Toshiba Mobile Display 2005 • http://www3.toshiba.co.jp/tm_dsp/press/2005/05-09-29.htm • A mobile touch screen display that could detect finger movements. • It could be used to ‘navigate through pages in the same manner as a conventional touch-screen approach’ • Similar to scrolling of items through a list with Apple’s touch screen

28. Is the '949 Invalid? • Based on the prior art of Portfolio Wall, Diamond Touch and Toshiba Mobile Display – yes. • Although Portfolio Wall is not a piece of hardware, when implemented on a computing device, the software interacts with the hardware to make a finger(s) touch-based device. • Portfolio Wall’s heuristics were similar to touch-based mobile devices available today. • The combination of the vertical scrolling from Diamond Touch and slideshow from Toshiba Mobile Display also contribute to the heuristics in today’s touch-based mobile devices.

29. Prior Art for '381 Patent? Finding prior art for the ‘381 patent has been difficult to find: document edge in screen auto-displays to configuration.
