The most important thing about this is: does this core technology belong to you? If this technology belongs to others, why should you use it for commercial use...
If you are not sure about this matter, then the questions you ask later will be meaningless at all. So what you have to do now is to first check whether this technology has been patented.
I’m not sure what you mean by “the Academy of Engineering has filed a record in the field of technical data”. “Filing” means filing with which unit and at what time; “recording” means applying or being Authorization, or just a literal filing.
But this is how I feel. Since you call this technology core technology, its importance is self-evident, so it cannot be a public technology. Otherwise, if it is an open public technology, you Why doesn’t the company I’m applying for use it? There are only two possibilities: 1. This technology has not yet been made public; 2. It is already someone else's patented technology.
If it is someone else’s patented technology, then this matter ends here. If you use it, it will be patent infringement and you will be legally responsible. If it is not yet public, don’t rush to apply for a patent. You said that the original technical information came from your tutor. Can your tutor agree to your application for a patent? Because applying for a patent means disclosure, and there are also things about profit distribution, you have to consider these.
There is another question. Do these original materials belong to your tutor or the school or research institute where your tutor works? That is to say, does your tutor have the right to agree to your application for a patent? In short, there are many questions, and the existing materials really cannot give better answers.
You are asking anonymously. I believe you are also very sensitive to this issue and should try your best to protect yourself, but I still hope you can provide more information. Otherwise, others really can’t help even if they want to.
