The prior art nobody checked
Prior art is anything already available to the public, anywhere in the world, in any language, in any form. A team can be genuinely original and still be second - an…
New is the easy part. Inventive is the hard part.
Novelty is a single-document test and it is largely mechanical. Inventive step is a judgement about whether a competent, unimaginative person in your field would hav…
Your claim is broader than your invention
Breadth is not free. Every extra millimetre of claim scope pulls in more prior art and demands more disclosure to support it. A claim that reaches beyond what you ac…
Adding words does not make a claim stronger
It feels safer to describe the invention thoroughly in the claim. It is the opposite of safer. Every additional word is an additional condition that a competitor has…
There is nowhere to retreat to
Claim 1 will often not survive examination. What decides whether you still have a patent worth having is whether the drafter built a ladder of narrower, meaningful p…
You only described the one you built
A specification that describes exactly one implementation gives you exactly one implementation to fall back on. Alternatives you considered and rejected are some of …
The provisional that covered nothing
A provisional specification buys a date for the subject matter it actually describes. A two-page document that states the idea without explaining how it works buys a…
A granted patent can still be taken away
Grant is a decision by an examining office on the material in front of it. Section 13(4) says expressly that it carries no warranty of validity - and there are four …
The case turns on what one word means
Before anyone asks whether a product infringes, the court decides what the claim means. That single decision then governs both infringement and validity - which is w…
What you said to the examiner is a public document
Every argument, amendment and concession made to get a patent granted sits on a public file that anyone can inspect. It is the first thing an opponent's counsel read…
What you can and cannot change after filing
After filing, you can narrow, correct and explain. You cannot add. Every amendment has to be supported by what was disclosed in the specification as filed - which is…
Turning up to the hearing with nothing new
A hearing is the last chance to change the outcome before a decision is written. The Controller has already read the file, so repeating the written arguments achieve…
The invention changed after you filed
A patent application protects what it described on the day it was filed. Engineering does not stop on that day - and the version you eventually sell is often meaning…
This is the Ragulika IP Educational Criticality - our own editorial prioritisation device, to help you decide what to read first. It is not a legal score, it is not calculated from your facts, and it says nothing about the strength of any particular application.
