ii. stocking the product for the purpose of offering it for sale or selling, or using it; and
(b) where the patent is granted in respect of a process,
i. using the process; and
ii. doing any act referred to in paragraph (a) in respect of a product obtained by means of that process.
Section 32(5) further provides that the rights in a patent shall not extend to:
(a) acts in respect of articles put on the market in Saint Kitts and Nevis by the patentee or with his or her consent;
(b) the use of articles on an aircraft, land vehicles or vessels of other countries which temporarily or accidentally enter the airspace, territory or waters of Saint Kitts and Nevis;
