Before you brief a patent drafter

Run this before the first drafting meeting.

A specification can only contain what the drafter was told. These are the things drafters most often are not told, and most often need.

Tick anything that is true. Each tick opens a short note on why it matters. Nothing you tick is sent anywhere - it stays in this browser tab.

Can you state the technical problem in one sentence, with a number in it?Inventive step arguments are built on a stated problem and a measurable effect.
If yes: If you cannot put a number in it, the effect may be too vague to argue later.
Do you know what the closest existing solution is?Claim 1 should be written to step around the closest prior art deliberately.
If yes: Give the drafter the search results before drafting starts.
Have you listed alternatives for every component and step?Alternatives are your future amendments, and they must be disclosed on filing.
If yes: Two lines each is enough. The paragraph you resent writing is often the one that saves the case.
Do you know where the invention stops working?Boundary conditions are the narrowing amendment you will need under objection.
If yes: State ranges, sub-ranges, and at least one comparative example outside the working range.
Are you withholding any parameters as commercially sensitive?Withholding working conditions is how patents become insufficient and unamendable.
If yes: Either disclose them or keep the whole thing as a trade secret. A deliberately thin patent is the worst of both.
Have you agreed one word per component?Housing, casing and enclosure used interchangeably creates clarity and support problems.
If yes: Write a term list before drafting and check the finished draft against it.
Do the drawings match the text and the claims?Drawings are part of the disclosure and are used in construction.
If yes: Check every numeral against the description, in both directions.
Have you told the drafter what a competitor would build?Claim 1 has to catch the cheapest version a competitor could ship, not just your product.
If yes: Describe that version explicitly in the briefing.

Drafting quality is judged years later, by whether the document contains the amendment you need and the evidence you have to produce.

The invention exists but the record does not

A patent can only be as good as what the drafter was given. Where the technical record is a slide deck and a conversation, the specification ends up thin, the altern…

Thinking about filing?

Before anything is drafted, the useful work is establishing what is already public, what is genuinely yours, and what you can honestly claim.
