Which department should intellectual property management be concentrated in?

Intellectual property rights are divided into patents, trademarks, trade secrets and copyrights. In fact, this is more of a legal issue. It is definitely not appropriate for laymen to be managed by the marketing department. Especially PCT, Madrid trademark international registration, intellectual property evidence preservation, intellectual property investment, cooperative development, etc. Professionals are needed, so the operation and management of intellectual property rights should still be placed in the legal department. The legal department should be subdivided into intellectual property department, litigation department and investment management department. Take Toshiba Corporation of Japan as an example. Toshiba's intellectual property department consists of seven business departments: planning department, technical and legal department, software protection department, patent department I, patent application department, design trademark department and patent information center.
