Changes to patents fees come into force on 6 April 2018.

The rules make changes to some existing patents fees and introduce some new fees for lengthy patent applications.

The legislation making these changes was laid in Parliament on 16 November 2017.

These changes follow on from our consultation, which received comments from 23 respondents.

As explained in the government’s response document, we have adjusted the proposals in light of the comments we received. The legislation makes the changes set out in the response document.

We will publish detailed guidance on how these fee changes will operate in practice, in due course.
