Therefore, one may see a different patent number format from the same patent office depending on the time period when the patent was issued. Also note that some patent offices may use a different format after the patent is granted as compared to when the patent application is under examination (e.g. the US patent office), while others (e.g. EPO or China) keep the same number series but use the\u202f<a href=\"http:\/\/patentwiki.iamip.com\/kind-codes\" target=\"_blank\" rel=\"noreferrer noopener\">kind code<\/a>\u202fto distinguish them.&nbsp;<\/p>\n\n\n\n<p class=\"has-black-color has-text-color\">A patent number indicates that a product or invention is protected by a patent application, which means that the patent owner has all the rights to this invention and can stop others from using it without a license. It is therefore usual to find patent numbers inscribed on a commercial product or in the product documentation to indicate ownership of the rights and to prevent others from unlawfully copying the solution.\u202f&nbsp;<\/p>\n\n\n\n<p class=\"has-black-color has-text-color\">The following table shows the currently used patent number formats from selected patent offices.
