Hi Cran, bug, dave
Cran you are very right.
Bug : if you want to deposit a patend or an idea, just send it under a stamped envelope to a lawyer and ask him to keep it.
I france we have a good and cheap system called "enveloppe Soleau" : for about 100 euros (don't know exactly) you can send an invention in this famous envelope with only a description of the content of your invention. so, if someone wants to know what's in, he must contact you and buy it.
I learnt that some companies don't hesitate to buy a serie of envelopes, expecting to find a pearl.. sometimes it works, but it can be bluff
, i invented the machine that turns BS into gold..interested ?
.
regards.
