English to Chinese Law/Patents Law: Contract(s)

All molds, tooling and implements of manufacture used solely in connection with Buyer’s Products Seller produces hereunder on a contract manufacture basis (“Implements of Manufacture”) shall {at all times} remain the exclusive and permanent property of Buyer, even if prepared in whole or in part by Seller.

其中的at all times, 翻译为“一直”是否正确？
另外，能否翻译为“无论何时”？
