What is implied by importation in relation to working of a patent under the Convention?

Importation is considered as working of patent, provided the patented product is manufactured in a member country and is imported into another member country which has also granted a patent on the same invention to the same applicant. Imagine that a product X has been patented in two member countries A and B. The product X is then manufactured in country A and imported into the country B. This product X shall enjooy the same patent protection in the country B even though it has been manufactured in the country A. This would also be considered as if the patent has been worked in country B.  more
