Find troublesome to ask for quotes and/or due dates? – Automatically calculating rough estimates regarding Japanese patents.

We understand that it may be troublesome for foreign clients to ask a Japanese representative for quotes and/or due dates a multitude of times.  For such clients, we constructed a unique website that automatically calculates rough estimates of fees and due dates regarding Japanese applications from the filing through prosecution thereof.

Please understand that the fees and due dates are approximate calculations. Particularly, the due dates are calculated on the assumption that: 1year = 365days and 1month = 30days.  If you need a precise estimate, please just let us know the International Application and/or Publication Number of the case of interest to you.
