The sales mentioned in the first paragraph may occur in China or abroad. When the "selling" behavior occurs abroad, not only the "importing" behavior is not regarded as infringement, but also the use, promise and sales of the imported products in China are not regarded as infringement.
After the revision of the patent law in 2008, the first article actually includes the international exhaustion of patent rights. That is, whether the patentee or licensor has obtained the patent right abroad or not, it is not infringement for the buyer to import the purchased products into China after selling the patented products.
Hope to adopt.
