If our company cooperates with branches of other companies, can we use their trademarks (written in the contract), and what other issues need attention?
If you cooperate with a branch of another company, it depends on whether he has the right to dispose of the trademark. General branches have no right to dispose of the company's rights unless they have special authorization. If it is unauthorized, you can't sign a trademark with the branch. If the branch has the right to dispose of it, you should first look at the scope of activities or authorization of the branch.
