Yep, totes give it away for free and put all the scesmatics / technical details online etc. So many accounts of dudes have the next best innovative breakthrough etc thta just seems to disappear from view after announcement. Reminds me back in late 80's early 90's a NZ guy had what he claimed was a breakthrough in car battery technologically - was on the national news etc, i can not recall the actual specifics i was a bout 15 or some such - from memory something about the battery would never need to be recharged under normal operating conditions and able to be made smaller and for less cost - distinctly recall the guy saying he was in talks and close to signing a major distribution deal with Ford Motors NZ (before they closed down and moved offshore) and expected them to be on sale within the next 12 months or so. Zip. Clearly he signed away all the IP or similar and then got shafted by 'manufacturing delays and distribution issues etc' until they just tell him it's 'not profitable for us to pursue in the long term and btw we own all the rights - you only own a percentage of royalties on future sale'.
