I know there are similar question out there. I am slightly specific about my question.
Say, there is an overall machine "TookAllTheIdeasMachine" by Inventor "PlayedWithWordsForHisFirstInvention", which achieves functionality A. Functionality A has many sub-functionalities, like SF1, SF2, etc. To achieve functionality SF2, the inventor owner used elements E1 and E2. To achieve functionality SF2, he used Processes P1 and P2.
My questions are:
Scenario 1: I being a new inventor, created a product with the only goal to achieve functionality SF1. I used exactly elements E1 and E2 and exactly same process P1 and P2 to achieve functionality SF1.
Do I have any grounds to get a patent for my invention?
If no, inventor "PlayedWithWordsForHisFirstInvention" has not come up with the small unit which only performs dedicated task "SF1" but my invention does. And because my invention is dedicated to functionality "SF1" and fairly not complex, It is cheaper. But because "PlayedWithWordsForHisFirstInvention" has created a heavily costlier invention, I cant bring my invention to market because I cant afford to be sued.
How can I get patent for my invention SF1?
Please assist me.
