Conclusion and remark
Conclusion 1PICMET2016, Hawaii
1. a high structuralize market; with a minority of core firms holding large patent transactions.
2. core firms and periphery firms are rear transaction.
3. core firms have developed as social closure clusters to trade their technologies.

Conclusion 2PICMET2016, Hawaii
1. a mature period in a patent transaction market is exhibited as clusterization
2. a small-world structure whereby a limited number of players maintain large technological or patent monetization portfolios.

Conclusion 3PICMET2016, Hawaii
• GO’NPEs: the role of governmental organization NPEs are notable in each period. They play the roles of technology provider, integrator and intermediator.
• Co’NPEs: Although the commercial NPEs can act as arbitrager, they can also promote transaction.
• PE: most transaction actors are patent practicing entities and act as technology providers, intermediators, and absorbers in a technology transaction chain.
