Xerox Patent Ruled Invalid, palmOne Exonerated
An anonymous reader writes "palmOne has issued a press release, that a court has found that the patent that Xerox was using to sue Palm for its character entry method, and was developed in house, didn't infringe because the patent was invalid." The case was first brought against 3Com Corporation back in 1997 before they spun off the Palm brand name.
I can't stand Graffiti 2... maybe its just because I spent so long using the original Graffiti, but it would make my day if it came back.
Man, some of these lawsuits get handed down through the generations (computer time). I bet 3Com/Palm/palmOne is glad to see the end of this. In each year's company report, they had to keeping listing it in the Oh Yeah, We're Being Sued section.
One line blog. I hear that they're called Twitters now.
Now what is Palm doing to do about Graffiti?
They had previously let go of Graffiti and developed their own Graffitti2. and made everyone learn new keystrokes. If they go back now, everyone who learned Graffiti2 is not going to be happy However, I'd be willing to bet that not everyone has upgraded, and many, if not most, are still using Graffiti1. Maybe they will include both, and have the user decide?

I'm sorry, what's dumb about this patent?
My understanding of the algorithm is that Xerox devides the Graffiti area into 9 ``blocks.'' The recognition algorithm tracks which block the stylus starts in, the end block, and the blocks through which the stylus travels. The recognition is fast and accurate, because each letter is simply an encoding of (start, end, intermediate blocks).
This algorithm is neither dumb nor obvious. Palm copied PARC's Graffiti alphabet because the algorithm was so elegant.
Have you tried Graffiti 2? It's slower and less accurate.
