I was doing some research on some other issues when I came across this rather broad patent that seems to cover querying a SPARQL endpoint (perhaps any RDF data store) with anything but SPARQL. Basically it seems to be a patent on converting one query language to SPARQL they cite "an SQL query, a query in XQUERY format, a query formatted as an HTTP request, etc."
