Patent Criticalities
The things that quietly decide whether an invention can be protected - explained before they cost you anything.
Showing 56 of 56.
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…
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…
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 …
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…
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…
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…
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…
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…
Why a good invention still gets a Section 3 objection
A section 3 objection is a subject-matter objection, and it is answered by evidence and framing rather than by arguing about the prior art. Each clause has its own t…
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 …
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 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,…
Nobody can tell exactly what the claim covers
A claim has to define a boundary that other people can find. Words like substantially, approximately, optimal, efficient and high-strength push that boundary into fo…
The same thing has three different names
It matters more than it seems. If the description calls something a housing, a casing and an enclosure, an examiner has to decide whether those are one thing or thre…
The specification never says what problem this solves
Inventive step is argued as a story: this was the problem, this is what the field taught, this is why our solution was not obvious. If the specification never states…
Why the drawings can decide the case
Drawings are read as part of the disclosure. A well-made set can support a claim term that the text handles clumsily; a careless set can contradict the text and crea…
The title is not the important part
The title identifies the application. It does not define scope, it is not construed, and no infringement was ever decided on it. Inventors regularly spend an hour on…
Searching once, at the wrong moment
Most organisations search once, just before filing, and treat the result as a verdict. Searching is more useful when it is treated as a repeated activity with a diff…
The wrong people are named as inventors
Inventorship is not authorship, seniority or reward. It is a factual question about who devised the invention **as claimed** - and because claims change during prose…
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 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…
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 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…
Filing before anyone asked whether it was worth it
Patentability and value are different questions, and organisations that only ask the first one accumulate portfolios that cost money every year and defend nothing.
The danger of filing too early
Filing early is usually right. Filing before there is anything to describe is not. A premature application starts clocks - twelve months to a complete specification,…
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…
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 …
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…
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.…
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…
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 …
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…
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…
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…
Published is not granted
Publication makes your application public. It does not make it enforceable. Between publication and grant you have privileges and rights as if the patent had been gr…
Why clarity objections arrive
Clarity objections look minor and are often answered carelessly, by adding limitations to make the point go away. That is the expensive route. A clarity objection is…
Why enablement and support are different objections
Support asks whether the claim is fairly based on what you described. Enablement asks whether a skilled person could actually perform it across the claim's width. Th…
Why unity objections arise
A unity objection is not an attack on your invention. It is the examiner saying that one application cannot cover all of this - and it creates a decision with a dead…
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 …
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…
The patent that only covers what you already sell
There is a version of every application that will be granted: the one narrowed to precisely what you already sell. It is also the version competitors do not need to …
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 application that died on paperwork
Substantive objections get the attention. Formal ones end just as many applications, because they carry the same deadline and are easy to leave until last.
Everything is obvious once you know the answer
Once you have read the invention, the route to it looks inevitable. Combination objections often rely on that effect - so the reply has to force the analysis back to…
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 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 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…
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.
Keep going.
Every explanation here links to the ones next to it. Follow the thread rather than the menu.

Patentability, infringement, prosecution strategy and every other IP outcome turn on the specific facts and on the law and Patent Office practice as they stand at the time you act.
