Anhui Agricultural University College of Economics and Technology didn't get a degree certificate. Can I get a patent?

Of course. Patent application has nothing to do with age, education and degree certificate. Patent application documents can be submitted directly to the Patent Office or entrusted to a formal patent agency. Patent application doesn't need physical objects or samples at all. What needs to be protected is well-thought-out design ideas, as long as the innovation can be clearly described in words.
