You may have developed an innovative product that others copy, infringing registered design rights. This problem has a different set of challenges given that copycat products are often described and promoted in ways to avoid trademark infringement.
As such, a starting point is usually to agree with clients where the priority online "places" are to monitor and enforce. Again, these are often areas which sit closely to where genuine product is sold in volume.
The priority is to reduce or eliminate the risk of sales of genuine product being substituted with illicit copycats.
This type of project is very well suited to our emphasis on human analysis. Often the only indictors we have to work by are product images which indicate design infringements. Product description, price, customer feedback are usually of little assistance with this type of project.
Additionally, a multi-lingual approach is normally crucial to find and act upon copycats which are sold internationally.
