Detail

In order to be effective, this form must be filed before the office has completed the preparations for publishing your application under Section 16(1) of the Patents Act 1977. The restriction will not be effective after the grant of a patent on the application.

Next steps

When we receive your request, we will:

  • tell you when we deal with it
  • publish the restriction at the same time as we publish your patent application
  • tell you about any requests to access samples of the biological material

The restriction will end when we grant the patent or if it is withdrawn or refused.

Cost

No fee.
