Provisional application - what to include


A provisional patent application is not examined and will never have a patent granted on it, but it gives you 12 months to decide whether to go further and seek standard or innovation patent protection for your invention.

Your provisional application should include:

What to include in the provisional specification?

A provisional specification should be drafted carefully and include as full a description of your invention as possible. It is not required to have claims.

A title should appear on the first page.

A provisional specification should also:

  • be in English
  • be on single-sided A4 pages
  • have separate pages for drawings (and claims if included)
  • allow sufficient margins (i.e. at least 2.5cm) around the edges of all pages.
The provisional specification should not include photographs.

Remember - filing a provisional application on its own does not give you patent protection

All provisional applications lapse after 12 months. If you do not file a complete application associated with the provisional, or file a PCT application within this 12 month period, you will lose any priority that your provisional application may have provided.
