Category 9 mainly includes trademarks for scientific instruments, including smartphones, earbuds, and network communication equipment. The transfer process of all trademarks can be divided into submission of application, acceptance, review, publication and issuance of trademark transfer approval certificate, etc. Before that, you need to sign a transfer contract and an agency contract with the platform, or between the seller and the buyer. The required fees generally include transfer fees, agency service fees, and trademark purchase fees. The transfer price of a Class 9 trademark on Yuzhao.com is usually between 10,000 and tens of thousands, and the agency's service fee is usually 10% of that.
