fom the quality and detail of the diagram describing the patent, apple's engineers must get through many tub loads of wax-crayons when filling out the patent applications.
it is truly ludicrous, presumably they'll be sueing Amazon now for their wish lists and shopping cart, and no doubt, samsung for including NFC chips and tags in their phones (even before apple themselves have yet to do)
I dont mind people applying for and using patents to protect genuine products and systems,
Apple just seem to use a scattergun approach to patents on anything and vague ideas on the bag of their fag packets, whether or not they have a product in mind.
Then they use them to intimidate other mansufacturers from designing actual products and stifling any true innovation that might some along.
