Patent criticality
The description is thinner than the claim needs
How much technical detail does a patent actually need?
A patent is a trade: a monopoly for a teaching. If the teaching would not let a competent person in your field reproduce the invention across the width of the claim, the trade fails - and insufficiency is a ground of revocation, not just an examination objection.
What sufficiency really requires
Enough that the skilled person can perform the invention without inventive effort of their own, across the whole scope claimed. That scales with breadth: the wider the claim, the more the description has to carry.
In practice the gaps are always the same. Process conditions that are described as suitable rather than stated. Compositions given as effective amounts. Models described by their outputs rather than their architecture and training. Results asserted without the comparison that would make them meaningful.
The commercial instinct that causes it
Applicants withhold the working parameters because they are the valuable part. That instinct is understandable and it is fatal. A patent that does not teach is a patent that can be revoked - and you have published everything else anyway.
If the parameters are genuinely too valuable to publish, that is an argument for keeping the whole thing as a trade secret, not for filing a deliberately thin patent.
Section 10(4) of the Patents Act 1970; insufficiency as a revocation ground under section 64(1)(h).
The 2025 CRI Guidelines address sufficiency for AI and machine-learning inventions specifically, requiring the functionality to be described specifically enough to be reproducible.
Have someone in your field who has not seen the invention read the draft and tell you what they still cannot build.
Treating the specification as a marketing document with the good parts removed.
Any phrase where a number should be.
Circle every adjective in your draft that is doing the work of a number. Replace them.
