Up to date legal status for all CN patents
Legal status data for all CN patents is now received and loaded weekly directly from the Chinese patent office. The legal status of over 1 million CN patents are being updated in our database because of this new legal status source. The impact is particularly important for patents which have lapsed due to lack of payment of fees this information is now available 3-6 months faster.
