So basically your argument is that putting your hands over your eyes and
yelling "blah blah blah blah" at the top of your voice is going to make
the evil monsters go away?
My GPS came with a sticker on the front listing about 45 patent numbers,
and I assume everybody else's did too. I can hardly claim ignorance of
the possibility that some of the stuff it does could be covered by
somebody else's IP. I have used Google Earth, Tom Tom, Multimap, and so
on and so forth, and I'm smart enough to guess how a lot of it works.
Reading the actual patents isn't going to change anything.
The only reliable way to make a patent go away is to show *prior* art,
not independent art! I work with beziers and NURBS all the time, it
would take me about 10milli-seconds to "invent" a mapping system that
used them, but unless I can show I did it before the application date of
whatever patent, it ain't going to make much difference. Sure you *can*
appeal a patent on grounds of it being trivial, but it should have been
assessed on that regard already, so you will have a much harder time
than you think. (IANAL blah blah)
That said, there are definite advantages in not knowing about how other
people do things, because that does, in my opinion lead to innovation.
But OSM is well on the way to being an army - lots of people here are
already very knowledgeable about the way various aspects of IP involved
here. Nobody needs to know it all, and most of us don't need to know any
Spending 1000 man hours coding around a potential problem would be well
worth it, if it protects 100,000 man hours of mapping!
