This Apple crowd need a bloody nose.
They have done some pretty UI stuff. That's it . Zilch other real innovation.
I designed a small tablet with touch screen back in 1987. Basically any such device has certain obvious features that NO-ONE should be able to copyright or patent as they are too obvious.
1) Rectangular as skinny as possible.
2) Rounded corners.
3) Screen takes as much of front as is possible.
4) Icons on the main screen for all the commonly used functions (Since Xerox in 1970s)
5) Maybe a button or two separate from screen.
My was called the Pen and Pad.
The "pen" had a 2.5mm optically read ball and option for ink (as you can make IR transparent black or coloured ink). Microphone near tip, Earphone at top. Three buttons. WiFi, Bluetooth etc didn't exist then so the Cordless link for voice and data from Pen to Pad was 60kHz Ultrasound. OK the FM receiver had doppler shift issues if you waved it about too much.
If any good lawyer wants to work on a no-win-no-fee maybe the lapsed patent can be revived and we sue EVERY blue tooth headset maker .... :-) I don't think so.
It's time Judges, Juries and patent offices did some real research and stop all this nonsense.
Of course there was the same thing in 1920s over valves and 1930s, 1940s on Radio and TV patents.
Not to mention the despicable behaviour of "Enforcers" of Cine Camera patents at the dawn of Cinema (Nickelodeon isn't a Documentary, but it gives the flavour well).
