Carve-Out and Divestiture IP Checklist: Asset Identification and Splitting, Shared and Retained Rights, Transitional Licences and Services, Recordation and Registry Updates, and Brand Migration Milestones

By ·

A ten-phase working checklist for the intellectual property workstream in a carve-out, divestiture, or spin-off, usable on either side. Phases one and two run the asset identification interviews and build the four-bucket schedule. Phases three through five settle the house mark, the patent cross-licences, and the software, data, and know-how layers. Phases six and seven cover the transition services terms and the separation agreement provisions. Phases eight through ten cover recordation, brand migration, and post-closing governance. Each phase closes with a gate.

How to use this checklist

Two facts organise everything below.

The register does not know which business owns anything. It says the parent company. The allocation must come from the operating business, which makes Phase 1 the critical path and the only part of the workstream that cannot be compressed.

Every continuing arrangement needs an end date and a consequence. Transitional licences, transition services, and cross-licences without them become permanent, and a separation whose purpose was independence ends with two companies still contractually joined.

Start Phase 1 at the first serious conversation about a divestiture, not at signing. A seller that begins before a buyer is identified negotiates from knowledge; one that begins after exclusivity negotiates from discovery, and every discovery is a concession.

The doctrinal background is Splitting a Company in Two; the operational treatment with worked engagements is Executing an IP Carve-Out; the cluster is assembled in the Carve-Out, Divestiture, and Brand Separation Toolkit.

The interview script

Phase 1 works or fails on the quality of the interviews, and a standard script makes them comparable across dozens of conversations.


The weekly report to the deal team

The intellectual property workstream is invisible to a deal team unless it reports in terms they act on, and a one-page weekly format does that.


The brand migration milestone set

A migration plan needs milestones somebody can verify, and the same set works across most separations.


A closing note

Almost nothing in this checklist is doctrinally difficult. The doctrine occupies a handful of provisions: no assignment in gross, quality control to preserve the mark, a signed writing for copyright transfers, and the joint ownership default that makes co-ownership unattractive.

What makes separations hard is that they require an organisation to describe itself accurately, on a deadline, for the first time — and most organisations cannot, because nobody ever needed them to.

Which is why Phase 1 carries the whole exercise, why it cannot be compressed, and why the single most valuable thing an adviser can do is start it before anybody has agreed a signing date. Everything else in this document is what to do with the answers.


Five things to say at the first meeting

Key Authorities at a Glance

The trademark constraint is 15 U.S.C. § 1060, prohibiting assignment in gross, with 15 U.S.C. § 1127 making an uncontrolled transitional licence an abandonment risk — the exposure illustrated in Barcamerica International USA Trust v. Tyfield Importers, Inc.. Enforcement after the split runs through 15 U.S.C. § 1114 and 15 U.S.C. § 1125, with cancellation grounds at 15 U.S.C. § 1064.

Patent allocation runs through 35 U.S.C. § 261 and is constrained by the joint ownership default at 35 U.S.C. § 262. Copyright transfers require the signed writing at 17 U.S.C. § 204, with categories at 17 U.S.C. § 101, initial ownership at 17 U.S.C. § 201, and recordation at 17 U.S.C. § 205. Know-how depends on 18 U.S.C. § 1839 and 18 U.S.C. § 1836. Licence survival in insolvency is Mission Product Holdings, Inc. v. Tempnology, LLC.

Tyfield Importers, Inc. | 3 — the naked licensing exposure | | 15 U.S.C. § 1114 | 9 — enforcement after migration | | 15 U.S.C. § 1125 | 9 — unregistered marks and false association | | 15 U.S.C. § 1064 | 3 — cancellation after a defective assignment | | 35 U.S.C. § 261 | 4, 8 — assignment and recordation | | 35 U.S.C. § 262 | 4 — why joint ownership fails | | 17 U.S.C. § 101 | 5 — work made for hire categories | | 17 U.S.C. § 201 | 5 — initial ownership | | 17 U.S.C. § 204 | 5 — signed writing for transfers | | 17 U.S.C. § 205 | 8 — recordation of copyright transfers | | 18 U.S.C. § 1836 | 5 — trade secret claim over allocated know-how | | 18 U.S.C. § 1839 | 5 — the enumeration precondition | | Mission Product Holdings, Inc. v. Tempnology, LLC | Variants — licence survival in insolvency |

Marksy is not a law firm and this checklist is not legal advice. Assignment formalities, recordation requirements, and licence enforceability vary substantially by jurisdiction, and regulatory divestiture conditions impose their own constraints.
