I think we can see where all this is going.
The eventual 'dematerialisation' of GoogleGlass - especially in light of the recent instances of, er, TechRage against GG Beta-testing "Google Explorers". I wrote a couple squirts of high-vinegar vitriol about the concept of Google running a pay-to-test-their-tech racket, but seem to have misplaced the post - will link when I find it again. Also, this.
In the late 90s, I had my character Rose O'Rion wear a "SoftLens" - a contact-lens that ran software - in a 2000AD story. I pushed this idea further when I returned to the character with a prose story 3 or 4 years ago, having her run AR type 'augs' on her SoftLens and sending "HeadTexts", etc.
Not claiming to have invented the thing that Google are patenting (laughs) - there's a difference between the basic-conceptualising of something and creating a patent-able design-idea that is detailed enough that the thing can engineered and built at some point in the future. Plus, I'm pretty sure I copped the basic concept off someone else - Terrence McKenna, maybe?
Still that didn't stop Arthur C Clarke from dining out for decades on the story that he had "invented" telecommunications satellites because he had used a similar idea in a tale and was, therefore, owed millions in royalties.
