When does my trademark expire — and how long do I have?

All tools

About this tool

Enter your registration date and how many renewals have been completed to see every 7-year term (each runs to the day before the anniversary — registered on the 2nd, expires on the 1st), the renewal window (normal fee until 35 days after expiry), the late-renewal grace period (about 7 months 5 days after expiry) — and get flagged when a lapsed registration needs a fresh filing. Dates shown in both AD and Bikram Sambat.

Registration date

The date on your registration certificate (दर्ता प्रमाणपत्र). Marks run 7 years per term, renewable indefinitely.

English date (AD)

Terms run to the day before the anniversary: registered on the 2nd → expires on the 1st.

Or pick the registration date in BS

Selects convert straight to the English date above — the certificate's BS dates work here too.

Pick a registration date to see its term-by-term renewal timeline.

How many renewals have been done?

Each completed 7-year renewal moves the timeline to the next term.

Renewal cycles completed

Type 0 if this is the first term, 1 if it has been renewed once, and so on.

Enter your registration date and the number of renewals already completed to see every 7-year term, the normal-fee renewal window (35 days after each expiry) and the late-renewal grace period (a further 6 months, about 7 months 5 days after expiry) — and to know exactly when a lapsed registration must be filed afresh. Terms run to the day before the registration anniversary: a mark registered on the 2nd of a month expires on the 1st.
