About US


Established in 2020 by Oxo International Limited (HK), is a specialized broker platform for global trademark exchange.

We are committed to establishing a bridge between buyers and sellers to achieve secure and hassle-free exchanges of trademark rights and values. We take strict measures to ensure that only ownership-verified trademarks are eligible for sale on our platform, and our exceptional expertise enables seamless transfers of trademark ownership and domain names. Our platform guarantees, coupled with the trusted protection of PayPal and Escrow, instill unwavering confidence and peace of mind for our esteemed clients throughout the entire transaction process.

If you are a seller, there are certain requirements you need to fulfill:
 To ensure the legality of the transaction, you must provide legal proof of ownership.  You will need to authorize our platform to list your trademark for sale, manage the associated transaction matters, and hold the payment on your behalf until you, as the seller, have fully fulfilled your obligations. Additionally, it is crucial for you to understand that failure to fulfill your obligations within the specified time will result in the termination of the transaction and a full refund to the buyer.  An annual fee of $69.00 is required for each trademark listing.

If you are a buyer, you need to take good care of your trademark after the transaction.
 After the ownership transfer takes effect, it is strongly suggested that you engage your own attorney as the correspondent to take care of your purchased trademarks. If you are a U.S. citizen, you also have the option to designate yourself as the correspondent for your U.S. trademarks.  You will need to keep using the trademark in commerce to maintain its validity and defend it against challenges from 3rd parties.  You have to submit qualified forms and documents and pay government fees within specific time deadlines, to renew and maintain your trademark in order to keep it valid for the long term.
