Rank Ordering of Assignees

Moving from the team’s focused start looking at just 14 patents, they used the work they did on keyword development to create a database of over 17,000 patents that were related generally to ethylene vinyl acetate copolymer emulsion technology. From such a large body of work the analysis team segmented the documents by assignee. In the “Rank Ordering of Assignees” figure it can be seen that investors in this technology included those utilizing materials and applications, competitive suppliers of similar materials, and raw material suppliers.
