Due-date management
We use an automatic due-date management system that, when a starting date is entered, automatically calculates the official due date, in-house due date, and other essential dates. The system eliminates the possibility of due-date calculation errors.
The input of the starting date can also be performed automatically by exchanging data between the management system and the application/registration filing system. No manual input error can occur.
We determine a due date for a response from the client, which comes before the official due date, depending on the importance of the case. The client is reminded of the date - repeatedly if necessary.
Document management
A patent specification and drawings, as well as design drawings, are checked by a group supervisor or a management supervisor for format compatibility, proper content, and editorial errors when they are drafted. Before official filing, the management supervisor checks them again.
Bibliographical data is double-checked by an administrative supervisor and a management supervisor, no matter which law is applicable to the case: patent law, utility model law, design law, or trademark law.
