This section applies to SKTO: 'ix. Evidence satisfactory to AEGY that all patents, patent applications, know-how, trade secrets, and related intellectual property necessary for the operation or development of the business of SKTO, belong exclusively to SKTO and are free of all claims, liens, royalties or other encumbrances of any kind.'

Combined with the section you cited, it's boilerplate of mutual assurance re IP of both parties.
