Outline of Final Research Achievements |
This study analyzed features of essential patents in patent pools. We constructed three datasets including essential patents (V), background patents (B) cited by (V), control group patents (C) citing (B). We found that average application year of (V) is older than that of (C), which indicates the advantage of prior art. But patents of (B) and (C) have less cited and more citing patents than (V) and are older than (V). These results suggest that essential patents were invented with improvement of related basic patents to adjust their standards.
