The downloaded patterns provided by this website include two common formats, PNG and vector EPS. Although it seems that these patterns have no copyright, there are actually some restrictions on their use, the most important of which is to prohibit secondary sales (that is, packaging and selling the icons to others) and not to use the patterns in trademark registration. If you don’t understand Japanese, you can just throw it in and Google translate it into Chinese to get a general idea of the meaning.
