Intellectual Property (2nd edition)

Russia Small Flag Russia

A patent or trademark assignment agreement must be in written form and signed by both parties, otherwise the agreement is invalid.

An assignment transfers full ownership and thus must not include any restrictions or limitations on further use of the assigned patent or trademark.

Every assignment agreement between commercial entities must state what consideration is given.

A trademark assignment may not mislead the public or result in confusion as to the origin of goods or services or its manufacturer. This is the case if:

  • the assignor wants to keep in its name the trademark registration of certain goods or services that are similar to the assigned ones;
  • the assigned trademark is well known;
  • the assignor remains the owner of other confusingly similar industrial designs, company names or trademarks protected for similar goods.

An industrial design assignment is also prohibited if it such assignment may lead to confusion by the public as to the goods or their manufacturer.

The right to an appellation of origin of goods or to a company name cannot be assigned.

i. Patent

ii. Trademark
As for patents, a trademark can only be assigned in writing. It may either concern the entire trademark or be limited to specific goods or services. Such limitation cannot, however, concern a part of the French territory or a part of the sign itself (Article L.714-1 of the IPC). The parties can also decide to set a limited term to the assignment.

iii. Designs
A writing is not mandatory to assign a design though it is required to be enforceable against third parties (Article R.512-15 of the IPC). As for patents and trademarks, a design can be assign either in whole or in part, for a limited term. Such limitation cannot concern a part of the French territory.

Since the law of 7, July 2016 “on freedom of creation, architecture and heritage" a written assignment is required (Article L131-2 of the IPC) . In the past, a written assignment was only required for publishing agreements, performance agreements and audio.

Pursuant to case-law, these provisions should apply only to the original author and natural person.

Patents, trademarks and designs can only be assigned in writing. The assignment of a guarantee or collective mark must be registered in order to be valid.

There is no formal requirement for the assignment of copyright ownership, which may even be concluded orally.

In such cases, the agreement must be made in writing and approved by the shareholders meeting. Moreover, in case of joint ownership, the joint owner must obtain the agreement of the other owner(s). Moral rights are in general not assignable. However, the author can waive or allow a third party to exercise certain moral rights, which has the consequences of limiting the scope of these works. In any case, for evidence purposes and to avoid possible interpretation disputes, it is advisable to enter into a written agreement.

As they are tied to a specific product and not to a specific owner, PGI/POA cannot be assigned as such.

United Kingdom Small Flag United Kingdom

In general, in order for an assignment of IP rights to be effective under English law, it must be made in writing and signed by the IP owner (assignor). In some cases, for instance, to assign certain European rights including EU trade marks, EU (Community) designs and European patent applications, the assignment must also be signed by the recipient (assignee). It is therefore usually advisable for any document assigning IP rights to be signed by both the assignor and the assignee. If the IP right is jointly owned, in order to assign the whole of the right, each of the joint owners must sign the assignment.

It is possible in respect of some rights to have a partial assignment, but the position is complex.
