Evidence of Use search (EOU) Search is performed to help patent owners identify potentially infringing products in the marketplace. The purpose of EOU search is to identify products or processes in the market which are likely to infringe the patent holder’s patent or even patent applications.
The evidence gathering or Evidence of Use (EoU) generation approach varies with the type of claim. In the case of method and system claims, one generally relies more on web sources, product testing snapshots, and user manuals for gathering necessary evidences to generate the EoU map. However, in the case of CRM/CPP claims (computer-readable media claims), it happens quite a few times that one is not able to gather sufficient evidences from web sources, product testing snapshots, and user manuals. Thus, to establish a high value EoU map, detailed source code analysis and reverse engineering techniques for gathering evidences becomes imperative.
