1.Adam, a graduate of the NanLing School of Creative Arts, runs a gift shop in Mongkok. His shop specializes in selling a series of 5-inch-tall sculptures of Martian aliens designed and handmade by himself under the registered trademark of "L'Martian". His sculptures have been awarded the first prize in creativity by the Mongkok Society of Creators. However, he never applied for copyright for his sculptures.

This morning, he passed by a shop round the street corner and saw exact copies of his L'Martian sculptures. Looking at the details, he could tell that the sculptures were not made by himself, and they did not carry the trademark "L'Martian".

He also found in the same shop a series of tennis rackets on sale with the trademark "L'Martian".

Explain what Adam's legal rights may have been infringed.
