Actually, no. If you read the patent, you'll see that the light
remains invisible only until it hits an opaque surface. Then it
becomes visible. (See especially claim #3). So much for not being able
to patent a law of physics.
I, for one, have placed a photo of myself deliberately infringing this
patent on my personal web page. How many others want to join me?
