Ok I hope you can tell I`m simply trying to learn the ins and outs as I go along here I am a marketing person, My job is to create programs that will make people want to purchase your products and services, but... why would it make a difference if baking soda had been around a long time or not, a method patent is a method patent. I didn`t realize it mean it the product is only x number of years in existance or less.
As far as someone already having come up with the use before me I thought it had to do with who properly patented first. wasn`t it A G Bell who got the patent but there is an arguement that someone else actually invented first?
Just wondering how it works, if someone has the answers.
