Types of patents: patents of invention.

Notion of the invention: the definition of an invention includes any new product, method of manufacture, or an improvement in either of them.

Novelty: absolute universal novelty is required. An invention is new only if it is not anticipated by the prior art, which covers anything disclosed to the public anywhere and at any time, by means of a written or oral disclosure, by use or in any other way before the relevant filing date or the priority date validly claimed. There is no novelty grace period.

Exceptions to protection: the following are not considered to be inventions: (a) discoveries, scientific theories and mathematical methods; (b) principles, rules and techniques of doing business; performing purely mental acts or practicing any game; (c) varieties of plants, animal species or biological processes used to produce plants or animals. Sophisticated biological operations and the results of these operations are excluded; (d) methods of treatment of the human or animal body, whether surgical or clinical, and methods of diagnosis applicable to the human or animal body. However, this does not apply to the products used in any of these processes. Also, a patent is not granted if the invention itself or its application is contrary to the Islamic concepts.

The employee has the right to receive a remuneration to be agreed upon either amicably or to be assessed by a committee in the light of the various circumstances of the employment contract and the economic significance of the invention. Any particular agreement that prevents such rights from the employee is invalid. Also, the preceding provisions apply to the employees of government departments.

Modification of Protection after Registration

Rights of prior user: despite the grant of a patent, an establishment that, in good faith, manufactures, uses an industrial manufacturing process of a product, or makes serious preparations therefor, before the filing date of an application by another person, or before the priority date of the application pertaining to the same product or process, shall have the right to continue such acts. Assignment or transfer of the said right is only permitted with the other elements of the establishment.

Assignment: possible. The assignment must be made in writing and duly notarized and legalized by the competent authority. It should be recorded and published in the Bulletin.

License: possible; must be registered.

Multiple licensing: the granting of a license does not prevent the patentee from utilizing the patent or from granting a license on the same patent to another person, unless otherwise restricted in the original license agreement. The licensee may not assign the rights and privileges conferred on him unless such right is expressly stipulated in the license agreement.

Compulsory license: if a patent has not been exploited on a sufficient scale in the country within four years from the filing date or three years from the date of grant, whichever expires later, the Patent Office may grant a compulsory license for exploiting the patent to any person upon application, provided that the applicant proves his capability to exploit the patent fully. No compulsory license can be issued as long as the patented product is sufficiently available.

Patent exploitation by the government: upon the request of the competent authority, the head of the Patent Office may take a decision to have the invention exploited by a government authority in the Kingdom if the public interest requires so. The patentee will be reimbursed a fair remuneration.

Nullification: an invalidation request can be filed before the Grievance Committee.

Infringement: the patentee may sue, before the Grievance Committee (nominated to hear all disputes and appeals against decisions relating to patents), any person who exploits his invention without his consent inside the Kingdom. The exploitation of a product is embodied in the making, importing, offering for sale, or using the product as well as stocking such product for the purposes of offering it for sale, selling it or using it. Where the patent is granted in respect of a process, the patentee is entitled to the same right in respect of any product made directly by such a process.
