Is PCB Copy Legal? Ownership, Patents & Jobs We Decline

Is PCB Copy Legal? The Short, Honest Answer

PCB copy is legal when the person requesting the work owns the intellectual property, holds a license from the IP holder, or the board design is not protected by an active patent or enforceable trade secret. In practice, the vast majority of PCB copy projects we handle fall into one of these categories: legacy board recovery for equipment you own, reproducing your own discontinued design, or supporting authorized second-source manufacturing. What makes a project illegal is not the act of copying a circuit board—it is copying a board whose IP belongs to someone else, without authorization, for commercial gain.

Why the Question “Is PCB Copy Legal?” Keeps Coming Up

Hardware engineers ask this question more often than any other before submitting a board. The confusion stems from three overlapping—but distinct—areas of law: patent protection, copyright, and trade-secret doctrine. Each one applies differently to a bare PCB layout, a populated assembly, and the firmware running on it.

Adding to the confusion, the history of PCB reverse engineering shows that courts in different jurisdictions have reached different conclusions about what constitutes protectable expression in a circuit board. In the United States, for example, bare PCB layouts generally are not copyrightable because they are considered functional rather than expressive works. The Semiconductor Chip Protection Act of 1984 (17 U.S.C. §§ 901–914) covers mask works for ICs, but it does not extend to printed circuit board copper layers.

Patents are a separate matter entirely. If a specific circuit topology, component arrangement, or manufacturing method is covered by an active utility patent, reproducing it without a license can constitute infringement—regardless of whether you reverse-engineered the layout yourself or received Gerber files from a friend.

Five Ownership Tests That Determine Legality

Before we accept any PCB copy project, our intake process applies a straightforward ownership checklist. If you can satisfy at least one of the five conditions below, the work is almost certainly lawful in every major jurisdiction we serve.

If none of these apply, we decline the project—no exceptions. More on the specific jobs we refuse below.

Patent vs. Copyright vs. Trade Secret: What Actually Protects a PCB?

Patents

A utility patent protects a novel, non-obvious invention for 20 years from the filing date. If a specific circuit arrangement or board-level innovation is patented, copying it without a license is infringement. However, the physical layout of copper traces—the Gerber artwork—is rarely the subject of a patent claim. Patents typically cover the circuit function, not the trace routing. That distinction matters: reproducing the same schematic netlist with a completely new layout may still infringe the patent, while copying the exact trace routing of an unpatented design is generally permissible.

Copyright

In the U.S. and most EU member states, PCB layouts are classified as functional works and receive little to no copyright protection. The U.K. historically offered some design-right coverage for PCB layouts under the Copyright, Designs and Patents Act 1988, but even there, protection is limited to 10 years from first marketing or 15 years from creation. Schematics—as technical drawings—can carry copyright, but the underlying circuit idea they depict cannot be owned by copyright alone.

Trade Secrets

If a board was developed under confidentiality and never publicly sold, its design may qualify as a trade secret. Obtaining such a board through improper means (theft, bribery, breach of NDA) and copying it would violate trade-secret statutes like the U.S. Defend Trade Secrets Act (DTSA) or the EU Trade Secrets Directive 2016/943. Once a product is sold on the open market, however, the physical board is no longer secret—anyone who purchases it can legally disassemble and study it.

What About Firmware and IC Code?

This is where legality tightens significantly. Firmware stored in a microcontroller is software, and software is copyrightable. Reading out firmware from a locked MCU—often called IC unlock or chip decryption—carries additional legal constraints. Our policy: we perform firmware readout only when the client provides documented proof of ownership or authorization. You can read our detailed position on the legality of IC unlock, including the specific documentation we require.

In short, copying a bare PCB layout and copying the code running on that PCB are two different legal questions with two different risk profiles. Conflating them is the single most common misunderstanding we encounter.

Jobs We Decline—And Why

Roughly 10–15 % of the inquiries we receive are declined after our intake review. Here are the categories we refuse:

• Counterfeit production: Requests to replicate a branded product (logo, silkscreen, packaging) for resale as the original. This is trademark infringement and, in many jurisdictions, a criminal offense.
• Active-patent cloning without license: When the client cannot demonstrate ownership or licensing and the design is covered by a verifiable active patent.
• Stolen prototypes: Boards obtained from a competitor’s factory, stolen samples, or boards received in violation of an NDA. If the provenance is questionable, we ask for documentation. If it doesn’t come, we pass.
• Firmware piracy: Requests to read out and redistribute firmware the client did not author or license, particularly for resale or to undercut the original manufacturer.
• Military / export-controlled designs without clearance: Boards subject to ITAR, EAR, or equivalent export-control regimes where the client cannot provide the required end-use documentation.

We document every declined project internally so our team can spot patterns. If an inquiry feels borderline, we consult with the client and, when necessary, request a signed declaration of ownership before proceeding. Our lab and authorization policy explains the NDA and ownership-verification workflow in detail.

How We Protect Ourselves—and You

Every accepted project begins with a mutual NDA. For projects involving firmware readout, we additionally require a signed IP Declaration Form that states:

• The client is the rightful owner of the design, or holds written authorization from the owner.
• The board is not subject to active litigation.
• The client indemnifies our lab against third-party IP claims arising from the work.

This is not legal theater. We have enforced these terms, and we have walked away from five-figure projects when documentation could not be produced. That track record is why OEMs and repair operations trust us with sensitive boards—our recovered-board portfolio reflects the kind of legitimate, documented work we take on.

Jurisdiction Matters: A Quick Comparison

This table is a simplified overview, not legal advice. If your project involves a design with known patent coverage in a specific country, consult an IP attorney in that jurisdiction before commissioning any copy work.

Practical Guidance: How to Confirm Your Project Is Legal

1. Check patent databases. Search Google Patents, USPTO PAIR, or Espacenet for the product name, manufacturer, and key circuit features. If no active patent covers the board-level design, your risk drops substantially.
2. Gather ownership proof. Purchase invoices, original design files (even partial), employment records showing you designed it, or a letter from the IP holder authorizing the copy.
3. Separate the board from the firmware. If you only need the bare PCB reproduced—new Gerbers, BOM, and pick-and-place files—the legal threshold is lower than if you also need locked firmware extracted. Our step-by-step PCB copy process shows where firmware extraction fits (and where it can be skipped).
4. Use an NDA-backed lab. Working with a lab that requires documentation and operates under NDA protects both parties. It also creates an audit trail showing good-faith effort if a dispute ever arises.

Common Misconceptions

“If I bought the product, I own the design.”

No. Purchasing a product gives you ownership of that physical unit. It does not transfer IP rights to the design. However, it does give you the right to repair, modify, and study that unit—including disassembling the PCB. The line is crossed when you mass-produce copies for sale without authorization.

“Old boards are automatically public domain.”

Age alone doesn’t extinguish IP protection. A 25-year-old board may still be covered by a patent filed 18 years ago (2 years of remaining term). That said, the vast majority of boards older than 20 years have no active patent coverage, and many were never patented at all. The most common situations requiring reverse engineering involve exactly these kinds of legacy, out-of-support designs.

“Reverse engineering is always illegal.”

This is flatly wrong in every major jurisdiction. Reverse engineering for interoperability, repair, security research, and education is explicitly permitted under U.S., EU, and U.K. law. The key constraint is purpose: studying a design to understand it is legal; mass-producing unauthorized copies for commercial sale is not.

Ready to Verify Your Project?
