The particular technology I'm thinking of is no more than eight years old.
(And I believe design patents expire 14 years from date of filing.)  Still,
expired patents or not, VL and others would drag him into court simply
because they have the money to do so, thus sinking him financially before he
even got out of the gates.

But new patents must have an element of non-obvious originality to them;
otherwise a patent may not be granted and the owners of the prior art will
be at least entitled to a share of the product's profits.

Like I said before, if this man can create flexible dichroic color, he'd be
in fine shape -- anything else and he's in shaky territory.

I agree the LED thing is a bunch of bullshit.  Pandora's box is open, boys,
now stop comparing dick sizes and let's all get back to work!

The horse is already out of the stable; single, huge LEDs that are mechanically interchangeable with current PAR64 bulbs are being beta tested as you read this, and PAR56 and PAR40 sizes are on the way, as are non-dichroic MR16 sized LEDs in all primary colors. <g>
