Answer ... A party can obtain the right to use the invention and, in the case of an exclusive licence, the right to sue a patent infringer.

Answer ... The licensor can limit:

• the term of the licence;
• the geographical scope of the licence;
• the ways and scope of use of the invention; and
• the right to sub-license.

If the licence agreement is silent on the term of the licence, the licence shall be presumed valid for five years. In the case of an exclusive licence, the licensor cannot use the invention in the manner and scope covered by the licence unless the licence agreement provides otherwise.
