– International Patent Classification (IPC)- difficult

• IPC too many patents in a group to review


Cooperative Patent Classification (CPC)• Cooperative Patent Classification (CPC) will allow you to perform

a single classification search across multiple patent offices

• Joint (Global) Classification System Based on the European Classification system (ECLA)– More granular than the International Patent Classification (IPC)

system ECLA about 140,000 Entries CPC about 200,000 Entries

• CPC is International Patent Classification (IPC) Compliant

• Participants– EPO – USPTO– Korean Patent Office (KIPO)– China (SIPO)
