Limitations & cautions
A recorded assignment is public at the UK IPO, so cleaning a copy suits drafts and samples. The asset number itself can re-link to named parties on the register. Swap it too if you need a fully blinded sample.
Frequently asked questions
Is a recorded assignment public?
Yes. Once recorded, the assignment is on the UK IPO register. Stripping a copy here suits draft and sample files that you control.
Does the asset number stay?
By default it is flagged as a reference. Swap it for a label if the number could re-link the sample to named parties.
Are witness details removed?
Yes. The tool scans the execution block, so witness and signer names are flagged.
