Interesting looking around these patents.Some seemed too simple to patent...guess not.
Dunno much about how it works but to take out a full patent it costs heaps doesn't it,and to take out a provisional patent it's cheap.
There must be a great deal of waisted money tied-up on hopeless patents that are never used and simply left to expire....others are excellent ideas but are just not recognised.
Does anyone have more accurate/simplified info on this?
If only someone could pattent a 200cc engine so it fits into a 50cc bicycle frame,now that's something....i'de buy it.
