IP-assignment redaction is the removal of personal data from assignment deeds and creator records. US law requires the assignment to be in writing and lets you record it with the patent office (35 U.S.C. 261). That recorded original proves title, and it is public. The copy you circulate can safely lose home addresses and ID numbers.
When this applies
A buyer traces title from each creator to the company. The deed carries home addresses, ID numbers, and witness details. Clear those before the deed enters the diligence space.
How anonym.plus handles it
- Bring the deed into anonym.plus on your device.
- It flags creator, assignee, and witness names.
- Patent and asset references stay in place.
- Swap names for labels like [INVENTOR] and [ASSIGNEE].
- Save the clean document on your device.
What you need to provide
- The deed (DOCX, PDF, or scan).
- An operator (Replace keeps the text readable).
- Optional role map for creator and assignee labels.

Compliance achieved
- Leaves title provable, which 35 U.S.C. 261 ties to the written, recordable assignment.
- Cuts creator addresses and ID numbers, which a title check never needs.
- Keeps patent and application references whole for the register search.
- On-device work keeps creator data inside the firm.

Limitations & cautions
A creator name is often public in the patent record itself, so a swap may not give true anonymity here. Weigh that outside source before you treat the deed as anonymous.
Frequently asked questions
Does redaction break the chain of title?
No. The recorded assignment still proves the transfer. You circulate a masked copy for review while the signed original stays on file and on the register.
Why keep the patent numbers?
They are not personal data, and a buyer needs them to search the register. Only the people are labelled.
Can I process a scanned deed?
Yes. Local OCR reads scanned pages, so IDs in image files are caught.
