Patent family, pdf inquiry etc functions are restored. Please contact us if there is a problem.
We can not currently use the patent family, pdf inquiry function. The cause is due to usage restrictions due to excessive use of external EPO service. We are currently dealing. We are sorry for the inconvenience.
We updated the patent classification database. You can search by patent classification according to PMGS (Patent Map Guidance System) 9th edition of August 2017.
