Patent License Agreement Template and Key Clauses (2026)

What is a patent license agreement, and when do you need one? A patent license agreement is a contract in which the owner of a patent (the licensor or patentee) lets another party (the licensee) make, use, sell or import an invention covered by the patent, usually in exchange for royalties or fees. The patent stays owned by the licensor. The licensee gets a defined right to work the invention without being sued for infringement. You need one whenever someone will commercialise your patented technology: a manufacturer that will build the product, a company entering a new market under your technology, a research partner, or a cross-licence between two patent holders. It is also how a patentee who does not want to manufacture turns an invention into income. This article is general guidance, not legal advice. Patent licensing engages patent law, competition law and tax, which vary by jurisdiction, so have a qualified professional review one before you rely on it. ## Patent license agreement template Copy the block below and fill the bracketed fields. ```

PATENT LICENSE AGREEMENT This Patent License Agreement ("Agreement") is made on [DATE] BETWEEN: [LICENSOR NAME], [address] ("Licensor") AND [LICENSEE NAME], [address] ("Licensee") 1. DEFINITIONS "Licensed Patents" means the patents/applications in Schedule 1 (numbers, jurisdictions, status). "Licensed Products" means products covered by a claim of the Licensed Patents. "Net Sales", "Field of Use", "Territory" and "Term" are as defined in Schedule 1. 2. GRANT The Licensor grants the Licensee a [exclusive / sole / non-exclusive], [non-transferable] licence under the Licensed Patents to [make, have made, use, sell, offer to sell, import] Licensed Products in the Field of Use and Territory during the Term. [Sublicensing is permitted/not permitted; if permitted, on the terms in clause 9.] 3. ROYALTIES AND FEES The Licensee will pay: (a) an up-front fee of [AMOUNT]; (b) a running royalty of [X]% of Net Sales of Licensed Products; (c) a minimum annual royalty of [AMOUNT]; and (d) milestone payments as in Schedule 2. Royalties are reported and paid [quarterly] within [N] days of period end, with a statement of Net Sales. 4. RECORDS AND AUDIT The Licensee will keep accurate records and allow the Licensor to audit them on [N] days notice, [once per year]. Underpayment above [threshold] is paid with interest and the audit cost. 5. DILIGENCE [For exclusive licences] The Licensee will use [commercially reasonable] efforts to develop and sell Licensed Products and will meet the milestones in Schedule 2, failing which the Licensor may [convert to non-exclusive / terminate]. 6. IMPROVEMENTS Ownership of improvements: [each party owns its own improvements]; [the Licensee grants the Licensor a licence to improvements it makes to the Licensed Products on the terms in Schedule 3]. 7.

On infringement by a third party, [the Licensor controls enforcement]; [an exclusive Licensee may join or step in as Schedule 4 provides]. 8. WARRANTIES AND LIABILITY The Licensor warrants it owns or controls the Licensed Patents and may grant this licence. The Licensor does not warrant validity or non-infringement unless Schedule 5 says so. Liability limits are in Schedule 5. 9. SUBLICENSING [If permitted] Sublicensees must accept terms no less protective than this Agreement; the Licensee stays responsible and shares sublicence income as in Schedule 2. 10. TERM AND TERMINATION The Term runs until [the last Licensed Patent expires / N years]. Either party may terminate for uncured material breach after [N] days notice or on insolvency. On termination the licence ends and the Licensee stops working the Licensed Patents, subject to any sell-off period. 11. GOVERNING LAW AND DISPUTES Governed by the laws of [jurisdiction]; disputes to [courts / arbitration seat]. Signed for the Licensor: __________ Signed for the Licensee: __________

- **Royalties (clause 3).** Choose a structure (up-front, running royalty, minimums, milestones) and define net sales and licensed product with care. A minimum annual royalty protects the patentee when a licensee under-performs.
- **Diligence (clause 5).** On an exclusive licence this matters a great deal: because the patentee has handed over the whole market, it needs the licensee to actually work the invention. Tie diligence to milestones with a remedy if they are missed.
- **Improvements (clause 6).** Say who owns improvements made during the deal and whether they are licensed back. Silence here causes fights later.
- **Enforcement (clause 7).** Decide who sues infringers and who pays. An exclusive licensee often wants step-in rights; a patentee usually wants to keep control of its own patent. ## Common mistakes to avoid - Not putting the licence in writing, which in India makes it invalid under Section 68 of the Patents Act, 1970.
- A loose royalty base, so the parties argue over what counts as a licensed product or net sales.
- Granting an exclusive licence with no diligence or minimum-royalty terms, leaving a valuable patent idle.
- Ignoring improvements, so the parties cannot agree who owns later developments.
- Forgetting that the licence cannot outlast the patent; a running royalty that continues after the patent expires can raise competition-law problems in some jurisdictions. ## A note on jurisdiction Patent licensing rules vary by jurisdiction. - **India.** Section 68 of the Patents Act, 1970 requires a licence to be in writing, to embody the agreed terms and to be duly executed, or it is not valid. Recordal with the Controller under Section 69 affects the ability to rely on the licence as evidence of title or interest. India also has a working requirement and a compulsory-licence route under Section 84, available three years after grant where a patent is not worked, which licensing can help address.
- **United States and Europe.** Written licences are standard and recordal at the patent office can affect rights against later purchasers. Running royalties that extend past patent expiry can face antitrust or competition scrutiny.
- **United Kingdom, Singapore, Australia.** Licences are recognised and can usually be recorded; recordal rules and the effect of non-recordal on third parties differ, so check the local register. Across all of them, put the licence in writing, define the royalty base precisely and record it where recordal brings a benefit.

The ongoing work is the hard part: keeping grant, field, royalty and diligence terms consistent across licensees, checking each signed version for a weak royalty base or a missing minimum before you commit, tracking milestone and reporting dates, and keeping versions straight through amendments and sublicences. Drafting, reviewing, tracking and governing a patent licence can live in one AI workspace tuned to how your company licenses technology, so each term is flagged favourable, neutral or unfavourable to you, a clause can be changed in plain language with a tracked edit, and royalty reports, milestones and renewals stay in view. [Adira](https://adiralaw.com) is one tool built on a single shared workspace. This template alone is enough to put a fair licence in place; a workspace just makes drafting, review and tracking one connected job.
