If your database meets the requirements of the Copyright and Rights in Databases Regulations 1997 it is eligible for protection for a period of 15 years unless a 'substantial new investment' is made in the database, in which case the period of legal protection begins another 15 year period, meaning indefinite protection could be afforded to continually updated databases.
This is still less than the period of protection afforded by copyright (up to 70 years after the originator's death).
If you need any help understanding your database protection rights and how to ensure you're covered, just get in touch and we'll guide you through the details and advise on the next steps you can take.
