Circular Economy IP Checklist: Process and Sorting Technology, Recycled Content Substantiation, Take-Back and Refurbishment Terms, Feedstock Supply Agreements, and Certification Marks

By ·

A ten-phase working checklist for recyclers, reprocessors, refurbishers, brands running take-back programmes, and their advisers. Phases one and two inventory the business and protect the recovery technology and plant know-how. Phases three and four build the substantiation architecture and evaluate certification. Phases five through seven cover refurbishment and resale, take-back agreements, and feedstock supply. Phases eight through ten cover equipment licensing and data, producer responsibility obligations, and enforcement readiness. Each phase closes with a gate.

How to use this checklist

The circular economy is four industries wearing one label, and this checklist is written so that each can use the phases relevant to it without working through the others.

A reprocessor runs phases one, two, three, four, seven, and eight. A refurbisher runs one, five, six, and ten. A brand running a take-back scheme runs one, three, six, and nine. An equipment vendor runs one, two, eight, and ten. Everyone runs phase one.

Each phase closes with a gate. The gates are conservative deliberately: this is a sector where the exposures accumulate silently — an unsubstantiated claim running for three years, a know-how position that was never documented, an equipment licence nobody read — and the gate is the point at which somebody has to say out loud that the work is done.

The doctrinal background is What Happens to the Material. The operational treatment with worked engagements is Advising a Recycling or Circular Economy Business. The cluster is assembled in the Circular Economy and Recycling IP Toolkit.


Phase 1. Inventory the business


Phase 2. Protect the technology and the know-how


Phase 3. Build the substantiation architecture


Phase 4. Evaluate certification


Phase 5. Refurbishment and resale


Phase 6. The take-back agreement


Phase 7. Feedstock and supply agreements


Phase 8. Equipment licensing and plant data


Phase 9. Producer responsibility obligations


Phase 10. Enforcement readiness


The ninety-day sequence

For a client with none of this in place, the phases sequence naturally into three months.


The annual review


Failures this checklist prevents



Party-specific short forms

If you act for a reprocessor

If you act for a refurbisher

If you act for a brand running take-back

If you act for an equipment vendor



Three worked applications

The converter facing customer diligence

A packaging converter markets sheet at "50% recycled content". A customer's procurement diligence asks for the calculation.

The refurbisher receiving a manufacturer's letter

An independent refurbisher of commercial equipment receives a demand alleging trademark infringement and unauthorised repair.

The brand whose housings reappeared

A consumer brand finds genuine branded housings from its take-back scheme offered on a marketplace by an unrelated seller.



The four registers

Everything above produces documents. Four of them matter enough to name, and a client that maintains these four has done ninety per cent of the work.

The secret register

The claims register

The contract register

The product register, for refurbishers

Four spreadsheets. None of them difficult. Their absence is why so much of this sector's legal spend goes on discovering things it already knew and could not prove.


A note on proportion



Six questions to open every file with

Six questions, answerable in a morning, and between them they scope the entire engagement.



What good looks like

Seven statements. Very few operators in this sector can make all seven, and the ones that can negotiate from a position their balance sheets do not explain.


The underlying point is simple enough to state in one line: a sector built on limitation doctrines still has to keep records, because a limitation you cannot evidence is a limitation you cannot rely on when somebody finally asks.


Key Authorities at a Glance

The checklist draws on four bodies of law at once. Exhaustion, which gives the recovery sector its operating room, comes from Impression Products, Inc. v. Lexmark International, Inc. and Quanta Computer, Inc. v. LG Electronics, Inc., with the copyright analogue at 17 U.S.C. § 109 and Kirtsaeng v. John Wiley & Sons, Inc.. The repair line comes from Aro Manufacturing Co. v. Convertible Top Replacement Co. and Wilbur-Ellis Co. v. Kuther; the trademark rule on refurbished goods from Champion Spark Plug Co. v. Sanders and Prestonettes, Inc. v. Coty; and the practical obstacle to both from 17 U.S.C. § 1201 with 17 U.S.C. § 117.

The claims layer is 16 C.F.R. Part 260 against 15 U.S.C. § 45, enforced privately under 15 U.S.C. § 1125 with standing from Lexmark International, Inc. v. Static Control Components, Inc. and the compliance defence closed by POM Wonderful LLC v. Coca-Cola Co.. Certification runs through 15 U.S.C. § 1054 and 15 U.S.C. § 1127. The technology layer is ordinary patent law plus Diamond v. Chakrabarty, Association for Molecular Pathology v. Myriad Genetics, Inc., Funk Brothers Seed Co. v. Kalo Inoculant Co., Alice Corp. v. CLS Bank International, and Mayo Collaborative Services v. Prometheus Laboratories, Inc.; the know-how layer is 18 U.S.C. § 1836, § 1839, and Kewanee Oil Co. v. Bicron Corp..
