if the article has the word "patent" in the title...
...cue comments...
"I saw that in 1990..."
"Isn't that the same as (some completely unrelated technical field)..."
"That must be obvious..."
"How stupid could you be - can it really have taken 15 engineers to put that together?"
"PRIOR ART, PRIOR ART!!!"
BTW folks - it is perfectly allowable to transfer an idea from one technical field (e.g. car airbags) into another completely unrelated one (e.g. mobiles) and patent it.
Mostly because the engineers working on mobile phone casing/protection won't be up-to-date on NASA's thrusters...
And vice-versa - engineers from BMW don't usually consider that their airbags can be used on mobile phones...
it took a spark of ingenuity to make the connection, and usually some sort of technical hurdle - that, my friends, is an invention...
