UK patent applications
Our professional fees for preparing and filing a UK patent application
are typically between £2,000 and £6,000 plus VAT. UK Intellectual
Property Office fees are presently £405 as of April 2026 where the
application, search and substantive examination fees are paid online.
The cost depends principally upon the technical and legal complexity of
the invention and the amount of work required to describe it properly.
A relatively straightforward mechanical invention will generally cost
less to prepare than an invention involving advanced electronics,
software, chemistry or several interacting technical systems.
The quoted range is intended only as an initial guide. Before accepting
instructions, we normally discuss the invention with the applicant and
provide a project-specific quotation with a substantially narrower cost
range. Typically, +/- £400.
The cost of prosecuting an application after filing depends upon the
objections raised by the Patent Office and cannot usually be predicted
reliably at the outset. Subsequent prosecution work is therefore
normally quoted or charged separately. Again, we will confirm our
professional fees, and only undertake any action with formal client
instruction.
