need advice on selling my design

[nimonia]

thnx guys for the replies and comments.. patenting takes a few years here in my place so dont think its worth while and it costs a bunch too.. haha...

anyways guys.. i've had this idea and it was put in the deal.. u see i am selling them the design schematic and layouts and idea with a one time sum xx,xxx and instead of royalty i would supply them the programmed PIC heahaeeha so basicly the chip itself would be the royalty... every unit they come up wif they need one programmed PIC to go with it.. just somethign i wanna share with u guys who are kinda like in my situation too..

Yeah... something like Parallax already do with their BasicStamp... but with intelligence inside

Hi Luciano

I think the copy protection offered in PIC's is pretty strong. I recall seeing a project Published in the Silicon Chip magazine sometime ago where the author not only set the copy protect fuse, but also made it so that the actual program itself would be erased if any activity was detected on the programming pin.

So in other words, if this pin weren’t grounded, the internal program itself would erase the entire flash memory. This method is commonly known as suicide protection. Very extreme and used extensively throughout the 90's on some arcade game boards costing $2,000 upwards.
