Along with the great flourish in world trade, patent is becoming increasingly important for protecting intellectual property. Although there are many patent retrieval systems for patent information searching, most of them, especially Chinese patent retrieval systems, are based on database that cannot support the huge amount of accesses. Thus, it is necessary to develop more efficient patent retrieval system to satisfy the growing requirements. A Distributed Patent Retrieval Service Platform (DPRSP) based on Nutch is proposed in this paper, which enables users get more related patent information. The concept retrieval is introduced in DPRSP to make DPRSP can understand the users' query more precisely. The architecture of DPRSP is described in this study and the detailed implementation of DPRSP is also explained. Finally, we demonstrate how the DPRSP improves the efficiency of the Chinese patent retrieval significantly by an application.
