During examination of a pending patent application or after the patent is granted, the owner of the patent may change: 1) the original owner may transfer ownership to another entity or party, through an "assignment;" or 2) the original owner may retain ownership but change its name. The original owner should record the assignment or name change with the qyule最新电信一's Assignment Recordation Branch by filing a Recordation Cover Sheet along with a copy of the actual assignment or proof of name change.
