First Examination Report

An email arrives with a PDF attached and a date. That date is the single most important thing in it.

In simple words

The Patent Office's first written list of objections to your application, together with the prior art relied on. You have six months from its issue to put the application in order for grant, extendable by three further months on request.

Think of it as

A deadline with a document attached.

Why it matters

The six-month period runs from the date the report is issued, not the date you read it. The three-month extension has to be requested on Form 4 with fee; since the 2024 Rules that request can be made during the extension period rather than only before the six months expires. What you argue and what you give up here is permanent - it becomes part of the file anyone can read.

A simple example

A report issued on 4 March gives you until 4 September, extendable to 4 December on a Form 4 request with the prescribed fee. If nothing is filed, the application is treated as abandoned under section 21.

Common mistake

Amending the claims to whatever gets an allowance quickest. A granted patent with claims narrowed to your exact commercial product is often worth less than no patent at all, because it tells competitors precisely where the fence is.

Where it comes from
