Este parece ser el comportamiento esperado, según My Oracle Support ID de documento 2060374.1. Pero a partir de un poco de experimentación, parece que poner comodines el espacio de nombres en su XPath evita que suceda; entonces:
<patent>{$m/*:patent/@*}
{
for $i in $m/*:patent/*
return $i
}
</patent>'
Con sus datos originales (en 11.2.0.4) y serializados para formatearlos de manera más legible:
WITH tmpTable AS (
SELECT * FROM XML_DOCUMENT_TMP cm )
SELECT tt.xml_data ,
XMLSerialize(DOCUMENT
XMLQuery('declare default element namespace "http://schemas.thomson.com/ts/20041221/tsip";
declare namespace tsip="http://schemas.thomson.com/ts/20041221/tsip";
declare namespace tsxm="http://schemas.thomson.com/ts/20041221/tsxm";
let $patsLus := $m/patent/*
return
<patent>{$m/*:patent/@*}
{
for $i in $m/*:patent/*
return $i
}
</patent>'
PASSING tt.xml_data as "m" RETURNING CONTENT)
AS VARCHAR2(4000) INDENT SIZE = 2) ewXml
FROM tmpTable tt
WHERE tt.document_id in (1);

Eso no es idéntico a su original, pero ya no tiene la corrupción del espacio de nombres. Si puede hacer eso en su consulta real y si el comodín causa algún problema, es otra cuestión...
