Collision
In trade mark law, a collision is generally said to occur when the owner of an older, already registered trade mark has filed an opposition with the competent authority against the new, pending registration of a comparable trade mark. Under certain circumstances, however, this also refers to a trademark owner’s demand that another party renounce very specific word elements of the comparable trademark or the complete or partial use of the trademark name.

Collision monitoring
Collision monitoring is basically trademark monitoring with the preventive aim of preventing a possible collision. This is done primarily to protect the trademark owner’s existing trademark rights and to avoid costly court or out-of-court proceedings.
