Intellectual property licensing is usually discussed as though it were one thing. It is five, and they behave differently enough that treating them alike causes real damage.
The differences that matter most: how long the right lasts, whether you must supervise the licensee, and what happens when the licence ends.
Most agreements cover more than one right. A manufacturing deal bundles a patent with know-how. A consumer products deal bundles a trademark with copyright in the packaging artwork. Blending them under one set of terms is where problems start.
The five rights compared
| Patents | Trademarks | Copyright | Designs | Trade secrets | |
|---|---|---|---|---|---|
| Protects | How it works | Source identity | Expression | Appearance | Confidential information |
| Term | 20 yrs from filing | Indefinite with renewal | Life + 70 yrs | 15 yrs from grant (US design patent) | As long as secret |
| Registration required | Yes | No, but valuable | No, but valuable | Yes for design patents | No |
| Quality control duty | None | Yes — mandatory | None | None | None |
| Royalties after expiry | Prohibited | N/A, renewable | Until copyright ends | Until term ends | Can continue |
| Lost by disclosure | No | No | No | No | Yes, permanently |
Three of these columns produce most of the drafting errors. The quality control duty on trademarks, the prohibition on post-expiry patent royalties, and the irreversibility of trade secret disclosure.
Patents: term is the constraint
Twenty years from the non-provisional filing date, and royalties must stop when the patent does. Brulotte v. Thys, reaffirmed in Kimble v. Marvel (2015), makes a royalty tied to a single expired patent unenforceable.
Which makes remaining term a direct input to the rate. A licence signed with fifteen years left is worth several times one signed with four, on identical technology.
And the licensor keeps paying maintenance fees throughout — $2,150, $4,040 and $8,280 at 3.5, 7.5 and 11.5 years after grant. Those come out of the royalty before anything is profit.
Co-ownership is the trap. Each co-owner of a US patent can grant a non-exclusive licence without the others' consent and without accounting to them for the proceeds. A co-owned patent is therefore very difficult to license exclusively, because any co-owner can undermine the exclusivity unilaterally.
See patent royalty rates for rates by field and why the base matters more than the percentage.
Trademarks: quality control is not optional
A trademark indicates consistent source and quality. If the owner licences the mark without controlling what the licensee produces, the mark stops indicating anything — and can be deemed abandoned.
This is naked licensing, and it destroys the right itself, not merely the licence.
| Quality control provision | Purpose |
|---|---|
| Written standards and specifications | Defines the required quality |
| Approval rights over goods and marketing | Control before release |
| Inspection and sampling rights | Verification |
| Approved supplier lists | Consistency of inputs |
| Right to terminate for quality failure | Enforcement |
| Evidence of actual exercise | The clause alone is not enough |
Exercising the control is what counts. Courts look at whether the licensor actually supervised, not whether the contract said they could. A perfect quality control clause that was never used has been held insufficient.
Trademarks last indefinitely, so a trademark licence has no natural end date the way a patent licence does. Term has to be set deliberately.
Franchise regulation is the adjacent risk. A trademark licence bundled with a business system and ongoing support may be a franchise in substance, triggering disclosure obligations regardless of what the document is called.
Copyright: long term, and a termination right
Life of the author plus 70 years, or 95 years from publication for works made for hire. Copyright licences can therefore run far longer than patent licences.
US authors have a statutory termination right. Under sections 203 and 304, certain grants can be terminated after 35 years, and the right cannot be waived or contracted away. It does not apply to works made for hire.
| Copyright licensing issue | Why it matters |
|---|---|
| Work made for hire status | Determines who owns it and whether termination applies |
| Moral rights | Attribution and integrity rights, stronger outside the US |
| Derivative works | Whether the licensee may adapt, and who owns the result |
| Open source obligations | Copyleft terms can propagate to the licensee's own code |
| Media and format scope | Rights granted for formats that did not exist at signing |
Software licences carry the open source problem. Licensed code incorporating copyleft components can impose obligations on everything it is combined with. Diligence on the composition of the code matters as much as the licence terms.
Trade secrets: secrecy is the whole asset
A trade secret lasts as long as it stays secret, and not one day longer. Disclosure is irreversible — there is no restoring a secret once it is out.
Which makes confidentiality the operative clause, and it must survive termination indefinitely rather than expiring with the agreement.
| Requirement | Effect |
|---|---|
| Confidentiality surviving termination | Perpetual, not tied to the licence term |
| Defined permitted recipients | Need-to-know limits within the licensee |
| Return or destruction on termination | With certification |
| Marking and handling protocols | Evidence of reasonable secrecy measures |
| Restrictions on reverse engineering | Contractual, since reverse engineering is otherwise lawful |
Reasonable secrecy measures are a legal requirement, not best practice. Trade secret status depends on the owner taking reasonable steps to keep it secret. A sloppy licensing programme can destroy the right across every licensee at once.
Trade secret royalties can legitimately continue past patent expiry, which is why bundled patent-plus-know-how deals are structured with the components separated and priced individually.
Worked example: a bundled licence done badly and well
A manufacturer licences a coating technology: one patent, the process know-how, and the brand under which the treated product is sold.
The bad version
| Term | As drafted |
|---|---|
| Grant | "All intellectual property relating to the Coating Technology" |
| Royalty | 6% of net sales, single blended rate |
| Term | 20 years |
| Quality control | None |
| Confidentiality | Expires with the agreement |
Three separate failures.
| Failure | Consequence |
|---|---|
| Blended royalty covering the patent | Whole royalty vulnerable as patent misuse after expiry |
| No trademark quality control | Naked licence — the mark can be lost |
| Confidentiality expiring with the term | Know-how becomes public at year 20, destroying it |
The mark is the worst of the three. A patent expiring is scheduled and expected. Losing a trademark through naked licensing is losing a right that would otherwise have lasted forever.
The good version
| Component | Rate | Term | Key terms |
|---|---|---|---|
| Patent | 3.5% of net sales | Until patent expiry, then stops | Field limited to architectural coatings |
| Know-how | 1.5% of net sales | Continues while confidential | Perpetual confidentiality, return on termination |
| Trademark | 1% of net sales | Renewable 5-year terms | Written standards, approval rights, annual inspection |
Same 6% total. Structured so that each component ends when it should, and the trademark carries the control that keeps it alive.
The patent royalty falls away at expiry and the remaining 2.5% continues legitimately, because know-how and trademark rights have independent value and independent duration.
Annual inspections are diarised, because the clause alone would not save the mark.
Cross-cutting issues
Bankruptcy. Section 365(n) of the US Bankruptcy Code lets an IP licensee retain rights if a bankrupt licensor's trustee rejects the contract. The statutory definition of intellectual property does not include trademarks, so trademark licensees have historically been more exposed.
Tax. Withholding tax on cross-border royalties frequently drives deal structure more than the IP considerations do. Treaty rates vary widely, and allocation of a blended royalty between rights and territories has direct tax consequences.
Competition law. Exclusive grant-backs, tying to unpatented goods, resale price maintenance and territorial restrictions all attract scrutiny in the US and EU. Bundled licences draw more attention than single-right ones.
Recording. Practice differs by right and country. Recording a patent licence with the USPTO is advisable; some countries require licence registration for enforceability against third parties.
When licensing is the wrong answer
Licensing keeps the asset and all its costs with you.
| Ongoing burden | Falls on the licensor |
|---|---|
| Patent maintenance fees | $14,470 across a large entity patent's life |
| Trademark renewals | Indefinite, per class, per country |
| Quality control inspections | Mandatory for trademarks |
| Royalty monitoring and audits | Yours |
| Enforcement against non-licensees | Yours |
Most patents never generate a royalty at all. Only 41.4% of US utility patents granted in 2014 reached full term; 58.6% were abandoned when owners concluded the fee exceeded the value. See the patent survival curve.
Selling ends every row in that table for a single payment. For an owner without the resources to administer a licence, monitor a licensee and police the market, it is frequently the better outcome. See patents for sale.
Choosing which right to lead with
The same technology can often be protected several ways, and which right you license shapes the whole deal.
| If the value is in | Lead with | Because |
|---|---|---|
| A technical mechanism competitors need | Patent | Enforceable against independent developers |
| A process nobody can observe from the product | Trade secret | No disclosure, no expiry |
| Recognition and customer trust | Trademark | Indefinite, renewable |
| Specific code or content | Copyright | Long term, cheap to establish |
| Product appearance | Design | Fast, inexpensive, effective against copies |
Patent and trade secret are mutually exclusive for the same information. A patent publishes the invention in exchange for a 20-year monopoly. A trade secret keeps it hidden with no expiry, and no protection against a competitor who independently develops or reverse-engineers it.
The choice turns on detectability. If a competitor could tell you use the technique by examining the product, secrecy will not hold and a patent is the better trade. If the process is invisible in the output — a manufacturing parameter, a formulation step — a trade secret can outlast any patent.
Filing a patent forecloses the alternative permanently. Publication at 18 months destroys secrecy whether or not the patent ever grants, which makes this the one IP decision that cannot be revisited.
Intellectual property licensing: the checklist
- Identify every right being licensed separately, by registration number where one exists. Never grant "all IP relating to" anything.
- Price each right separately. A blended royalty covering a patent risks the whole stream becoming unenforceable at expiry.
- End patent royalties at patent expiry, and structure know-how and trademark components so they can legitimately continue.
- Build genuine quality control into any trademark licence — standards, approval rights, inspection — and then actually exercise it.
- Make trade secret confidentiality perpetual, surviving termination, with return or destruction and certification.
- Check work-made-for-hire status on copyright, and whether the 35-year statutory termination right applies.
- Diligence any software for open source components before licensing it.
- Confirm you have the right to grant. Co-owners, existing exclusive licences and security interests all limit what you can license.
- Specify territory per right. IP is national, and granting worldwide rights you do not hold gives away future markets for nothing.
- Price the ongoing burden — fees, renewals, inspections, monitoring, enforcement — and compare the net against simply selling.
