Whether the patent declared by others is legal.

Now the patentee is a company. Judging from the current situation, the rights of inventors and designers are occupied by others, and the landlord is not the technology owner, but the inventor. The technical service contract signed between the landlord and the company shall prevail. In addition, if the patent itself is designed by the landlord, but the company designer later changed the internal structure, it is also a contribution. It affects that you are the only inventor. If it's just adding people, it's definitely illegal. Then you can ask for correction. Or complain to the relevant departments of the patent office to safeguard the rights of its inventors.
