mtaht writes "I've just had the interesting experience of being deposed to talk about one of the first embedded, Linux-based, wireless routers. Our (free!) 1998 publication of how to make one predates patent #7035281, filed September 13, 2000, by someone else. Their patent was recently granted and is now being disputed in court, in part using our how-to as an example of prior art. The lawsuit continues; the case goes before a judge shortly, and a jury trial if necessary is scheduled for the spring. I find myself plagued with the question: So... who invented the embedded Linux based wireless router? What relevance does 'who' have, when there is such an enormous confluence of ideas from thousands of people? What constitutes invention, anyway?"
