Maritime IP Checklist: Design and Hull Form Protection, Shipyard and Transfer Terms, Classification and Survey Records, Equipment Supply Agreements, and Voyage Data Rights

By ·

A nine-phase working checklist for the intellectual property attaching to vessels, yards, and marine equipment. Phases one and two build the design and rights inventory and select the protection route. Phases three and four fix the shipbuilding contract terms and the classification record position. Phases five and six settle equipment software and voyage data. Phases seven through nine cover brands, transfer and finance, and enforcement readiness. Each phase closes with a gate that should not be passed until the items above it are complete.

How to use this checklist

This checklist assumes you act for a party with a vessel interest — an owner, a yard, a naval architect, an equipment supplier, a charterer, a manager, or a financier — and that you need to establish, in a defined number of steps, what that party holds and what it should do about it.

The nine phases run in order and each closes with a gate. The gates matter more here than in most checklists, because maritime rights positions are set by four documents written at the beginning of a vessel's life and everything afterwards is archaeology. A phase skipped is a document unread, and an unread document is where the unpleasant surprise lives.

The doctrinal background is in Registered Somewhere Else. The operational treatment, with negotiation guidance and worked engagements, is in Advising a Maritime or Shipbuilding Business. The full cluster is assembled in the Maritime and Shipbuilding IP Toolkit.

Adapt the phases to the party. An owner works phases one through six in order. A yard concentrates on phases one, three, and nine. An equipment supplier lives in phase five. A buyer in a sale and purchase works phase eight first and then backwards.


Phase 1. Build the vessel rights inventory


Phase 2. Select and execute the design protection route


Phase 3. Fix the shipbuilding contract terms


Phase 4. Establish the classification and survey record position


Phase 5. Negotiate the equipment supply and software terms


Phase 6. Settle the voyage data rights


Phase 7. Protect the brands and the shore side


Phase 8. Prepare for sale, purchase, and finance


Phase 9. Build enforcement readiness

Common failures this checklist prevents


Three worked applications

The newbuilding programme

A container operator ordering six vessels from a Korean yard with a European naval architect runs Phases 1 through 3 before signing anything, Phase 5 while the equipment specification is open, and Phase 6 before the systems are installed. It buys hull form exclusivity for a defined period in its own trades, secures a licence permitting modification and sister construction at any yard, requires the parametric model tied to a payment milestone, and files design applications on the superstructure before the design is publicised.

Without this, the operator gets six efficient vessels and a competitor gets the seventh.

The yard after a key departure

A yard whose production manager has joined a competitor runs Phase 9 in reverse: does an enumeration exist, were access controls in place, is there an exit record, and what did the individual actually touch? If the answer to the first question is no, the honest advice is that the immediate matter is probably unwinnable and the real work is Phase 9 for next time. Check also whether the methods should have been patented and whether the 35 U.S.C. § 102 grace period has expired.

The charterer denied its own data

A time charterer seeking consumption data to support a performance claim reads the charterparty first — Phase 1 — because many now contain electronic data clauses. If silent, its positions are contractual, practical, and procedural, in that order. The vendor holding the data is not a party and will not assist. The remedy is Phase 6 applied at the next fixture, and this one treated as a lesson with a price.



Party-specific short forms

The nine phases above are the complete programme. Most engagements need a subset, and the subsets differ enough by party that it is worth setting them out.

If you act for the naval architect

If you act for the equipment supplier

If you act for the charterer or manager

If you act for the financier



The annual review

Vessel rights positions decay quietly. Vendors change hands, managers change, charterers come and go, and the person who negotiated the build contract retires. An annual review of forty minutes per hull prevents most of the decay.


Documenting the work

The checklist is only as useful as the record it produces. Four artefacts are worth maintaining, and they are worth maintaining in a form a successor can read.

The vessel rights file, one per hull, holding the design agreement, the build contract rights clause, the equipment licence schedule, the data clause, and the class access confirmation.

The fleet software register, one row per system per vessel, with supplier, version, licence reference, transferability, escrow status, and telemetry destination. It is tedious to build and it answers half the questions that ever get asked.

The data map, one page, showing what each vessel generates, who receives it, under what terms, and what happens on termination. If it does not fit on one page it is not being used.

The brand and trading map, one page, showing where the fleet trades against where the marks are registered, with the gaps marked. Gaps are a decision, not an oversight, and the map is where the decision gets recorded.

None of these is complex. All four fit in a shared folder. The reason they rarely exist is that no single department owns the vessel's intellectual property position — the technical department owns the drawings, the commercial department owns the charter, procurement owns the equipment, and legal is consulted after something has gone wrong. The checklist's real function is to name an owner.


A closing note on proportion

Not every vessel warrants this. A single second-hand coaster trading regionally under a bareboat charter needs Phase 1, the transferability items in Phase 5, and nothing else. A series of purpose-built units carrying a proprietary hull form and a bespoke cargo system warrants the whole programme and probably a standing review.

Scale the work to the asset. What does not scale is Phase 1: the four governing documents should be read on every engagement, regardless of size, because the cost of reading them is an hour and the cost of not reading them is discovered years later, usually by somebody else, usually at the worst possible moment.

Key Authorities at a Glance

The maritime practitioner draws on four bodies of law that rarely meet. Patent territoriality is set by 35 U.S.C. § 271 and qualified for vessels by 35 U.S.C. § 272, whose ancestor Brown v. Duchesne still decides port-call questions. The extraterritorial boundary comes from Microsoft Corp. v. AT&T Corp. and, for damages, from WesternGeco LLC v. ION Geophysical Corp..

Copyright supplies drawing protection at 17 U.S.C. § 102, limited by the separability reasoning of Star Athletica, L.L.C. v. Varsity Brands, Inc. and by the idea-expression line of Baker v. Selden, with the registration prerequisites of 17 U.S.C. § 411, § 412, and Fourth Estate Public Benefit Corp. v. Wall-Street.com. The sui generis hull right at 17 U.S.C. § 1301 exists because Bonito Boats, Inc. v. Thunder Craft Boats, Inc. preempted state plug-moulding bans. Designs run through 35 U.S.C. § 171, Egyptian Goddess, Inc. v. Swisa, Inc., and Gorham Manufacturing Co. v. White. Trade secrecy runs through 18 U.S.C. § 1836 and § 1839, Kewanee Oil Co. v. Bicron Corp., and E.I. duPont deNemours & Co. v. Christopher, whose facts translate directly to an open building dock.
