PATSTAT vs Espacenet

Post by nico.rasters » Thu Feb 06, 2014 2:17 pm

See http://worldwide.espacenet.com/GB20040015870. It's a rucksack, by a Simon Stewart Mitchinson. He's both inventor and applicant.
The same patent in PATSTAT October 2013 has appln_id 21451471.
In PATSTAT there is no inventor listed, and no IPC classes. Just to be on the safe I also checked TLS222, TLS223 and TLS224 but they did not return anything either.
The rucksack patent is several years old, so that makes me wonder why the data that is available in Espacenet is missing in PATSTAT. Any ideas?
