Sony Applies for PSP Patents

Sony has applied for two patents that relate to their PSP, one is a keyboard and the other is a cell phone attachment. This explains why Sony would not support the Keyboard for the PSP from Logic 3 I wrote about before. No word on possible launch dates or pricing. Since the patents have just been applied for, I would not expect either device any time soon.
