Patents are not properly exported to MS Office 2007 XML when using Word 2016. Following little changes should be made:

exported as:
<b:Source> ... <b:Author> <b:Author> <b:NameList> ... </b:NameList> </b:Author> </b:Author> </b:Source>

It should be changed to:
<b:Source> ... <b:Author> <b:Inventor> <b:NameList> ... </b:NameList> </b:Inventor> </b:Author> </b:Source>

There are two files attached for a better view of the format.
