The first step in how to get a patent is to understand your invention. What aspect (or aspects) of the invention makes it new and useful? Suppose you made a custom pair of shears that are useful for cutting thin strips of fabric. The scissors have a custom designed handle with different shaped finger loops and an additional set of pivots that allow the cutter to feel the slightest resistance when cutting through very thin fabric.
Once you identify the aspects that make your invention new and useful then you need to consider the scope. Are there other ways to make your invention? For example, could you use springs instead of pivots? Could you change the shape of the finger loops or the materials they are made out of? Find all the possible ways to make your invention work, even if they’re not as good as the preferred way you make your invention.
