Protect your invention with a granted patent.
Legalkarobar.com takes your invention from patentability search through to grant with the Indian Patent Office — provisional and complete specification drafting, examination response, opposition defence, and PCT international filing, handled end to end.
Every stage from search to grant, handled in one place
Patent prosecution is a multi-year process with hard statutory deadlines — one team manages the filing so an examiner deadline or opposition notice never gets missed.
Patentability Search & Novelty Assessment
Prior-art search and assessment of novelty, inventive step, and industrial applicability before filing.
Provisional Application Filing
Filing a provisional application to establish an early priority date while the invention is finalised.
Complete Specification Drafting
Drafting and filing the complete specification with claims, description, and drawings for examination.
Request for Examination
Filing Form 18, or expedited Form 18A where eligible, to bring the application into the examination queue.
First Examination Report Response
Drafting and filing a response to objections raised in the First Examination Report within the statutory deadline.
Patent Opposition Handling
Representation in pre-grant and post-grant opposition proceedings before the Controller.
PCT International Filing
Filing under the Patent Cooperation Treaty to preserve the option of protection in multiple countries.
Patent Renewal & Annuity Management
Tracking and paying annual renewal fees required to keep a granted patent in force for its full term.
Built for inventors and companies with something genuinely new
If you've developed a new product, process, or technical method, one of these profiles likely matches you.
Startups & Deep-Tech Founders
You've built a novel product or process and want patent protection before investors, competitors, or the market see the full picture.
Software & AI Companies
Your invention is software-based and needs claims drafted around a genuine technical effect to navigate Section 3(k) correctly.
Manufacturing & Hardware Innovators
You've engineered a new mechanism, device, or manufacturing process that needs protection before it's copied or reverse-engineered.
Pharma & Biotech Companies
You're developing a new formulation, compound, or biotech process that needs specialised claim drafting for this technology area.
Individual Inventors
You've developed something on your own and want the full filing process — search, drafting, and prosecution — managed for you.
MSMEs & Research Institutions
Your organisation has ongoing R&D output and needs a structured, repeatable process for filing multiple applications over time.
Which filing route actually fits your invention?
The right first filing depends on how developed your invention is and where you eventually want protection — this is the comparison we walk every client through first.
| Application Type | Purpose | Key Deadline | Typical Cost Profile | Typical Use Case |
|---|---|---|---|---|
| Provisional Application | Establishes an early priority date | Complete specification due within 12 months | Lower initial filing cost | Early-stage inventions still being refined or tested |
| Complete Specification (Ordinary) | Full application ready for examination | Filed directly, no follow-up filing needed | Higher upfront cost, single filing | Well-developed inventions ready to file immediately |
| Convention Application | Claims priority from an earlier foreign filing | Must be filed within 12 months of the foreign priority date | Comparable to a complete specification | Extending protection from a foreign filing into India |
| PCT National Phase Entry | Enters India via an international PCT application | Must enter national phase within 31 months of priority | Deferred cost, single international filing upfront | Seeking protection in multiple countries, India included |

From search to grant, in four stages
A fixed process means nothing depends on you tracking examiner deadlines yourself.
Patentability Search & Strategy
We run a prior-art search to assess novelty and inventive step, and recommend a provisional or complete filing.
Specification Drafting & Filing
We draft the claims, description, and drawings, and file the application to secure your priority date.
Examination & FER Response
We file the examination request and respond to First Examination Report objections within the statutory deadline.
Grant, Defence & Renewal
We track the application to grant, defend against opposition, and manage annual renewal fees.
Claims drafted to survive examination, not just get filed
Most rejected or narrowly-granted patents trace back to claims drafted too broadly or too vaguely at filing. We draft with the examiner's objections in mind from day one.
The two things inventors get wrong most often
Publicly disclosing an invention before filing can destroy novelty
Presenting at a conference, publishing a paper, launching a product, or even certain investor demos before filing can count as prior public disclosure, which then disqualifies the invention from being novel when you eventually apply. India does have a narrow grace period for the inventor's own disclosure in specific circumstances, but relying on it is far riskier than simply filing before any public disclosure happens.
A provisional application isn't a placeholder you can ignore
Filing a provisional application starts a strict 12-month clock to file the complete specification, and missing that deadline means losing the priority date entirely, not just delaying the process. The provisional filing needs to describe the invention thoroughly enough to support the claims that will eventually be made in the complete specification.
Software patents live or die on how the claims are framed
An application that describes "a computer program that does X" is likely to be rejected under Section 3(k), while the same underlying invention, claimed as a technical method or system producing a specific technical effect, can succeed. This distinction is why software and AI patent applications need claims drafted with current Indian Patent Office practice specifically in mind, not adapted from a US or European filing.
Missing the FER deadline ends the application, not just delays it
Once a First Examination Report is issued, there's a statutory deadline to respond, and failing to respond in time results in the application being treated as abandoned — not paused, not extended by default. Tracking this date is one of the most operationally important parts of patent prosecution, and it's easy to lose track of across a multi-year filing.
What inventors say after filing their first application
We almost demoed our product at a conference before filing. Legalkarobar.com flagged the disclosure risk in time and got our provisional filed first.
Our software patent had been rejected once by a different firm's claims. They redrafted around the technical effect and it was accepted on the second attempt.
A competitor filed a pre-grant opposition against our application. They handled the entire hearing and we came out with the patent intact.
