Introduction to Technology Licensing

The aim of this page is merely to give a basic introduction to the concept of intellectual property licensing and to outline some of the points which may need to be considered when granting or taking such a licence. Throughout the page the term ""licensor"" is used for the person/company granting the licence, and ""licensee"" is used for the person taking the licence.

This page concentrates on the licensing of products and processes. Special considerations apply in the licensing of trade marks or brand names, and these are dealt with in the page entitled  Trade Mark Licensing.

What rights can be licensed?

The following can be licensed:

  • Patents/patent applications
  • Know-how (confidential information)
  • Copyright
  • Unregistered design right
  • Registered designs

First, be sure that the licensor actually owns the rights which are to be licensed. For example, it is widely assumed that a person or business which commissions copyright work is automatically the owner of the copyright. This is not correct, and the copyright needs to be assigned to the person or business commissioning the work.

In the case of patent licensing, you need to ensure that the intended licensor is the applicant in the relevant patent applications, or is the patentee in the case of granted patents. Within a group of companies, the identity of the appropriate licensor will depend on financial and organisational decisions and plans and possible tax considerations. Remember that a patent may well last up to 20 years. Once the appropriate licensor has been identified, it may be necessary to assign patents, patent applications or other rights to the licensor.

Which rights can be licensed?

A licensee can be licensed to carry out any of the acts (and not necessarily all of them) which would infringe any of the licensor's intellectual property rights if done without the consent of the licensor.

For example, a UK patent can be infringed by making, selling, using or importing the patented product without the consent of the patentee.

A licensee may therefore be permitted to carry out all, or any one or more, of these activities.

Another way of splitting the licensor's rights is by granting a "field of use" licence or licences. Here, the right given to the licensee is limited to a particular area of technology or industry or commerce. This kind of licence requires very careful drafting to ensure that the licensee's rights are clearly defined and delimited.

You can also split up the rights according to geographical area, so that a particular licensee is licensed to carry out a particular activity within a particular geographical area only.

Where the licensor owns rights (for example, patents) in different countries, separate licences may be granted under each of the national patents. Alternatively, a licensee may be licensed to carry out certain activities in a number of different countries in which the licensor owns intellectual property rights.

Competition laws must be considered in connection with restricting licences to particular countries. Certain terms which might be agreed between a licensor and licensee may not be permitted in a licence agreement under UK or European competition law, or the competition law of other jurisdictions. Parties to agreements that breach competition law prohibitions may be fined, and the terms of the agreements themselves may be unenforceable. For advice in this area, contact our Legal Team.

Is the licensee to be allowed to grant sub-licences?

In the case of a manufacturing licence, for example, it should be stated whether the licensee may have the products manufactured for it by another party, and whether the licensee may grant sub-licences to others to manufacture and sell products on their own account. The licensor may want to control the quality of the products being manufactured, or the parties may negotiate different royalty terms in respect of products manufactured or sold by sub-licensees.

How many licensees?

A licence may be an exclusive licence, a sole licence or a non-exclusive licence.

Once the licensor has granted an exclusive licence, no-one (including the licensor) except the exclusive licensee may do any of the acts which are the subject of the exclusive licence. If the exclusive licence covers all of the activities which would otherwise infringe the patent (for example), then the licensor has granted away his own rights, almost as if he had sold the patent to the exclusive licensee. Particular attention must be paid to competition law when considering granting an exclusive licence.

Under a sole licence, the licensor may continue to use the licensed rights himself, but he has contracted with the sole licensee that he will not grant licences to other parties.

Under a non-exclusive licence, the licensee may be one of many licensees. The power of the licensor to grant further licences has not been restricted.

Acknowledgement of licensor's rights

The licensor may require the licensee to mark all products manufactured or sold under the licence with an acknowledgement that they are, for example, patented products and are sold under licence from the licensor.


Whenever there is any prospect that the technology will be further developed, the parties should agree upon the ownership and use of the intellectual property rights in improvements which may be made in the future by either party.

For example, a common arrangement is that intellectual property rights in improvements belong to the party which has made the improvement, but that the improvement will be disclosed to the other party which will then have a royalty-free licence to use the improvement.

Although this is a common arrangement, it is by no means universal. The question of improvements is a matter for negotiation between the parties. However, competition law must be considered in this context as certain kinds of arrangement are prohibited. For example, an obligation on the licensee to assign to the licensor improvements that can be exploited without infringing the licensed technology (i.e. "severable improvements"), is generally not permitted.


Payment is usually by way of royalties, but may be by lump sum, or by a combination of the two.

The basis for calculation of royalties will depend upon the activity that is being licensed. In the most common scenario, where the licensee is licensed to sell, or to manufacture and sell, a patented product, royalties are usually expressed as a percentage of the "net sales value" of the product sold, after deduction of taxes and expenses such as carriage, insurance and packaging.

The definition of "net sales value" needs to be carefully drafted, so as to cover, for example, the situation where the licensee may sell the product at an undervalue to a subsidiary or associated business. It is also important to ensure that there is no ambiguity, so as to avoid the possibility of disputes arising in the future.

Provision should also be made in the licence for the licensee to provide the licensor with regular statements of manufacture and/or sales figures, and for these figures to be checked by an independent accountant if required by the licensor.

It is common to include provision for minimum royalties, so that the licensor is certain of receiving a minimum return regardless of the licensee's performance. In the case of an exclusive licence, this may be coupled with a provision for the licence to become non-exclusive if minimum sales figures are not reached. Alternatively, the licensee may have the option of either making up the royalties to the minimum figure or losing the licence, if the minimum figure is not reached.


The parties will need to decide whether the licensor is to be under an obligation to bring infringement proceedings against third parties at the request of the licensee, or merely to lend his name to proceedings brought by the licensee; and (most importantly) which of them will bear the costs of such proceedings.

One possible arrangement is that the licensee brings the infringement proceedings and bears the costs, but may set off the costs against royalties which would otherwise be due to the licensor while the proceedings are going on.

The licence agreement should also cover the possibility that a third party may allege that the activities of the licensee amount to infringement of intellectual property rights belonging to that third party. The licensor will usually want to make it clear in the licence agreement that he gives no warranty that the licensed activities will not infringe someone else's rights.

How long should the licence last?

A licence may last for any length of time up to the duration of the intellectual property rights concerned.

Patents, registered designs and unregistered design right have a fixed life span (subject to the payment of renewal fees in the case of patents and registered designs) while copyright can last for much longer, and know-how indefinitely.

It should be agreed which party will pay (and be responsible for paying) the relevant renewal fees.

It is sometimes appropriate to grant a licence for a relatively short period, but to include provision for the licence to be extended if the parties so desire upon the expiry of the initial period.

Termination of the licence

The licence should include a provision for the licensor to terminate the licence in certain circumstances, for example upon insolvency of the licensee, or in the case of a serious breach of contract by the licensee. There are standard terms covering termination which are often used in licence agreements.

Resolution of disputes

The parties may agree that any disputes are to be resolved by mediation or arbitration instead of in the courts. In the case of transnational licence agreements, the parties should also agree upon a choice of law clause (which State's laws govern the agreement) and a jurisdiction clause (in which State's courts the agreement may be litigated).

Recordal of licences

In most countries (including the UK), patent licences can be recorded and in some countries it is obligatory to record them.

It is generally in the interests of the licensee, rather than the licensor, to record the licence, and the licensee therefore usually bears the cost of doing so.

In the UK, the licensee will want to record his licence so that anyone who buys the patent from the licensor buys it subject to the licence, and so that he can continue to work under his licence even if the licensor later agrees to grant someone else an exclusive licence.

In the UK, an exclusive licensee may bring legal proceedings for infringement of the patent in his own name, but in order to obtain damages as from the date of the grant of the licence, he must register the licence within six months of its grant.
