Imperium IP vs Corsearch: First-Pass Screening vs Full Clearance
These are not substitutes, and any page telling you otherwise is selling something. Corsearch produces clearance-grade output for legal professionals across jurisdictions. Imperium IP is a first-pass US screen that runs in seconds and costs nothing. In a well-run clearance workflow, cheap screening comes first and full clearance follows on the survivors.
Imperium IP is a screening tool, not a filing service and not a law firm. It tells you how risky a name looks before you spend money on it. What you do next - file yourself, use a filing service, or hire a trademark attorney - is your call, and the report is built to hand over.

- Analyst review and structured similarity analysis designed for attorney workflows.

Questions
Can Imperium IP replace a full clearance search?
No, and it should not be used that way. It screens the US federal register and produces a preliminary risk read. It does not cover common-law rights, state registrations, foreign jurisdictions, or analyst judgment. A full clearance search and a licensed attorney remain necessary before adopting a mark.
How do attorneys actually use this?
As triage. Screen the full candidate list, discard the obvious collisions, and commit formal clearance budget only to names that survive. It compresses the early cycle without touching the rigor of the clearance step itself.
Does it cover international marks?
No. Imperium IP covers the USPTO federal register. Any name intended for international use needs jurisdiction-specific searching, which is exactly what enterprise providers like Corsearch offer.
