My understanding is that
first draw a two-dimensional coordinate diagram
the vertical axis unit is the number of patents and the horizontal axis unit is the number of patentees
and then count the number of patents and patentees of this technology every year
according to the annual order (from small to large). Point out the position of the number of patents and the number of patentees in this year on the graph
and then connect the points in the order of the year
This graph is called the technology life cycle graph in patent analysis, which judges the development cycle of this technology according to the ratio of the number of patents to the number of patentees, and is divided into: germination stage, growth stage, maturity stage and decline stage
. It is very long to say, so you are interested in further inquiry.
