I don't know if you developed it yourself or something. . What is the big difference with the existing online shopping mall model? . If not. Because the existing online shopping mall model has become a well-known technology. Then you can't apply. Because of the lack of freshness. . . A patent must have three characteristics: practicality, novelty and creativity. . . So it depends on your current technology or your thinking concept.
If all the conditions are met, you can apply for a patent for invention.
If you just want to protect an online mall you designed, then you can consider applying for copyright protection.
