Regarding Spanish material on Espacenet, experience has taught us that the purported priority date displayed next to any given Spanish patent within inventor-based results is actually the Spanish filing date, as opposed to the earliest and international priority date. Publication date data is being treated as date granted.
Precise relations between this patent and non-Spanish predecessors are yet to be determined.
