Where Patents Break
The same failures repeat at four points in a patent life. Here is what goes wrong at each of them, and why.
Stage
Before filing
Everything that happens before a single form is submitted - and most of the damage that cannot be undone.
Filing abroad first, without permission
A person resident in India may not apply outside India for a patent without written permission from the Controller, unless an application for the same invention was …
Nobody wrote down who owns it
An invention belongs to its inventors unless something in writing moves it. Filing in the company's name does not by itself transfer anything. Ownership defects are …
The danger of filing too late
Late filings fail in three different ways, and only one of them is about competitors. Your own disclosure becomes prior art against you. Somebody else files first. A…
The twelve months that decide your international position
Twelve months from your first filing, you must either file in each country you care about, or file a PCT application that preserves the option. There is no third cho…
You told the world before you told the Patent Office
In India there is no general grace period. If your invention was made available to the public before your priority date, that disclosure is prior art against your ow…
Nobody decided what the priority date was for
Priority is not a property of your application. It attaches, claim by claim, to whatever was fairly disclosed in the filing you are relying on. Treating it as a sing…
The application is in the wrong name
The applicant is who will own the patent. Getting it wrong affects fee category, chain of title, who can sue, and what an investor sees in diligence - and correcting…
The data you did not generate
In chemistry, biotechnology, pharmaceuticals and food technology, several of the objections you will face can only be answered with comparative data. If nobody gener…
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…
Stage
During drafting
The specification is the only thing that will be read in ten years. This is where scope is won or lost.
Claim 1 describes your product instead of your invention
Claim 1 is the patent. If it recites the specific product you happened to build - your materials, your dimensions, your architecture - then a competitor only has to …
Your specification does not support your claim
You can only claim what you described. When an examiner cites prior art and the obvious answer is to add a limitation you never wrote down, there is nothing to amend…
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…
Software claimed as software
You cannot patent a computer programme per se. You can, on current Indian authority, patent an invention that happens to be implemented in software if it delivers a …
The description is thinner than the claim needs
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 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…
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 …
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…
Stage
During examination
The Patent Office writes back. What you concede here follows the patent for the rest of its life.
Most applications do not fail. They stop.
Very few Indian applications are refused after an argument. Most simply end because a date passed - and because there is no decision to appeal, there is often nothin…
Nobody asked the Patent Office to look at it
An Indian patent application is not examined unless someone files a request and pays for it. If the request is not filed in time, the application is treated as withd…
The reply that quietly gave the patent away
A first examination report is an opening position, not a rejection. The two ways applicants lose value here are missing the date, and buying a grant by conceding mor…
The thirty-one months that ended the case
If a PCT application does not enter the Indian national phase within thirty-one months of the priority date, it is treated as withdrawn so far as India is concerned.…
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…
Somebody is reading your published application
Publication makes your application visible to everyone who competes with you. In some industries, opposition is a routine part of the landscape rather than an except…
The divisional you could no longer file
A divisional application must be filed before the parent is granted. That is a moving target you do not control - and it is the single most common way that valuable …
The form that can revoke a patent
Section 8 requires you to tell the Indian Patent Office about corresponding applications filed abroad. It is administrative, it is easy to overlook in a large family…
The invention is new - and still not patentable
Indian law has a filter that operates completely independently of novelty and inventive step. Section 3 lists things that are not inventions at all - and something c…
Stage
After grant
A granted patent is a beginning, not an ending. It has to be kept alive, kept clean and, sometimes, defended.
A granted patent does not mean you are free to sell
A patent is a right to stop other people. It is not a licence to practise your own invention. Your product can be simultaneously protected by your patent and blocked…
The patent died of neglect
Renewal fees are due from the expiration of the second year from the date of the patent, and each year after. Miss them and the patent ceases to have effect - usuall…
The working statement nobody filed
India requires patentees and licensees to tell the Patent Office whether a patent has been worked in India. The obligation moved from annual to once every three fina…
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 …
Nobody enforces your patent for you
Granting a patent and enforcing it are done by completely different institutions. The Patent Office has no role once a patent is granted - enforcement is a civil act…
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…
The licence that could not be enforced
Most licence disputes are not about royalty rates. They are about who may do what, where, and what happens when something changes - and those are the clauses that ge…
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.
Keep going.
