Can a word constitute a trademark, patent or work?

"Word" cannot constitute a patent; A patent is the shape, structure or method of a product; Generally speaking, a single word does not generate copyright unless it adopts a unique design, which is very artistic and can generate copyright. You can apply for a single-word trademark, but if no one else has applied for it before, such as a trademark in Jin Jiu, and if the word is more artistic, its meaning will be stronger and the success rate of applying for a registered trademark will be higher.
