Hello, there is no patent right for a LOGO attached to a painting or calligraphy work, only a copyright
The copyright is automatically obtained after the work is completed
But if the company commissions the design , or as a company employee designing for the company, the copyright belongs to the company
Your interests and benefits are the salary paid to you by the company. Otherwise, if you do nothing and get paid, of course it is because you made the LOGO. , you only get paid if you do other things
