Patent Filing in India for Companies and Large Entities: Fees, Compliance and Portfolio Control
This category covers applicants who do not fall within the concessional groups: companies, partnerships, limited liability partnerships, trusts and other legal persons that are not startups, small entities or educational institutions, along with foreign corporations filing in India directly or through the national phase. An applicant is placed here by what it is on the date of filing, not by revenue alone. A joint application that includes such an applicant is generally treated at this level even where one of the other applicants would have qualified for the concession on its own.
Applicants in this group pay the ordinary level of the First Schedule, which is higher than the level available to natural persons, startups, small entities and educational institutions. The Rules also distinguish electronic filing from filing on paper, and additional charges apply where a specification exceeds prescribed limits on pages and claims, which matters for large chemical and software filings. No declaration of status is needed for the ordinary level, but the position reverses when a company acquires an application from a concessional applicant: the Rules require the difference between the two levels to be paid when the transfer is requested. Build that into acquisition and spin-in budgets, and read the current First Schedule and Rule 7 before approving a filing programme, since the amounts and the excess-page rules change with amendments.
Rule 24C does not list companies of this kind as a category in their own right, so eligibility usually rests on a different ground. Common routes include applications where India was selected as the international searching or preliminary examining authority in the corresponding international application, applicants eligible under an arrangement for accelerated processing with a partner office, and applicants in a sector notified by the Central Government for this purpose. The Rule has been amended more than once and the grounds must be checked in the version in force. The request attracts a higher official fee, and the Rules also contemplate converting a pending ordinary request into an expedited one on payment of the difference.
We do not publish rupee figures anywhere on this site. Fee schedules change by notification. How fees are structured.
Research done in India, filed abroad first
Multinational groups often route inventions to a parent company for a first filing in the United States, Europe or Japan. Where the inventors are resident in India, section 39 restricts applying for a patent outside India for that invention unless an application has first been filed in India and the period the section requires has passed, or written permission has been obtained under Rule 71.
Captive research centres are the usual pressure point. An invention disclosure raised in Hyderabad or Pune moves into a global filing committee, and the first filing decision is taken in another jurisdiction on cost grounds.
The control that works is procedural. Flag the residence of every named inventor at the disclosure stage, and route any case with an India-resident inventor through the foreign filing check before instructions leave the company.
Keeping the section 8 position accurate across a family
Section 8 places a duty on an applicant who is also prosecuting the same invention outside India to inform the Indian Patent Office about those corresponding applications, and Rule 12 governs the statement and undertaking involved. The Controller may also require details of prosecution abroad.
The duty is continuing. Large families acquire new members long after the Indian statement was filed, and the Indian file is often handled by different counsel from the family as a whole. Nobody notices until an examination report or an opposition raises it.
Treat it as a data problem. Keep a single family table with country, application number and date, and make an update to the Indian file a standing step whenever a new national filing is made.
Inventors, contractors and getting title on the register
Ownership in a corporate group can look obvious internally and be untidy on paper. Section 68 requires assignments to be in writing and duly executed, and the Rules deal with presenting an assignment to the Controller and registering title and interest.
Three situations cause most defects: work done by contractors and vendors without an assignment clause; inventions from an acquired business where the chain of title stops at a company that has since merged; and inventors who leave before signing.
Recordals also matter for corporate events. After a merger, a name change or an internal transfer, the register entry should be updated so that the entity taking action against an infringer is the entity that appears as proprietor.
The deadlines that lose rights quietly
Nothing announces itself. A request for examination must be filed within 31 months under the Rules as amended in 2024, or the application is treated as withdrawn. Publication follows at 18 months from the priority date, which sets the date from which certain rights are calculated. Renewal fees keep a granted patent alive across a term of 20 years from the filing date, with an extension of up to 6 months available on payment of the prescribed fee.
Rule 138 allows the Controller to extend certain time periods or condone delay, subject to conditions and an outer limit of 6 months, on a request made in the prescribed manner. It is a remedy, not a plan, and it does not reach every deadline.
For a portfolio of any size, the docket is the control. Confirm each deadline against the current Rules rather than against an internal note written before the 2024 amendments.
Third parties will read your file
A published application invites attention. Section 25 provides for opposition to a patent, in a pre-grant form available to any person and a post-grant form available to interested persons, which must be brought within 12 months from the date of publication of the grant. Rule 55 and the following Rules set the procedure.
Competitors also use the file for their own freedom to operate work, and anything inconsistent between your Indian statements and your foreign prosecution can be raised later in revocation proceedings under section 64.
There is a reporting side too. The Act empowers the Controller to call for information from patentees about the working of a patented invention, and Rule 131 sets out the form and manner for those statements. Missing statements are an avoidable compliance failure for a company with many granted patents.
Your checklist, in order
- Record the residence of every named inventor at the disclosure stage and route India-resident cases through a foreign filing check before instructing counsel abroad.
- Maintain one authoritative family table and update the Indian file whenever a new corresponding application is filed abroad.
- Audit invention assignment clauses in employment, contractor and vendor agreements, and close gaps for acquired businesses.
- Record assignments, mergers and name changes with the Patent Office so the register matches the entity that would enforce.
- Docket 18 months, 31 months, examination responses and renewals, and reconcile the docket against the current Rules after each amendment.
- Check excess page and claim charges before filing long specifications, and consider whether claim sets should be restructured.
- Decide early whether a divisional application is needed, since section 16 requires it to be filed while the parent application is pending.
- Calendar the working statements and any other periodic filings for granted patents in the portfolio.
Mistakes this group makes
- Letting a global filing committee choose a first filing country without checking whether any inventor is resident in India.
- Filing the section 8 statement once and never updating it as the foreign family grows.
- Acquiring a startup's pending application without budgeting for the difference in fee levels that becomes payable on transfer.
- Leaving the register showing a merged or renamed entity as proprietor until enforcement is needed.
- Assuming Rule 138 will rescue any missed date, when it is limited in scope and capped at 6 months.
A semiconductor group files from its Hyderabad design centre
The account below is fictional and compressed to show the sequence. Trilok Semiconductors India Pvt Ltd runs a design centre in Hyderabad for a foreign parent. Two engineers resident in India devise a power gating scheme that cuts idle current in a sensor chip. The group's practice is to file first in the United States. Before instructions go out, the India patent counsel flags the residence of both inventors and the section 39 position is addressed, so the sequence of filings is fixed deliberately rather than by habit. The Indian application is filed at the ordinary fee level, and the claim set is reviewed because excess claims attract additional charges. Over the next two years the family grows to five countries, and each new filing triggers an update to the Indian file under the section 8 duty. When the parent later reorganises and the Indian subsidiary is renamed, the register entry is corrected. The docket carries publication, the examination request and renewals with named owners.

Questions people ask
Is there any fee concession for a large company in India?
No. The concessional level of the First Schedule is limited to natural persons, startups, small entities and educational institutions as defined in the Rules. A company outside those definitions pays the ordinary level. What a company can control is the cost drivers within its own filing practice: the number of claims and pages, whether filing is electronic, how many divisional applications are generated, and how disciplined the portfolio review is about letting weak cases lapse rather than renewing them.
We are filing jointly with a startup. Which fee level applies?
Where an applicant outside the concessional categories is one of the joint applicants, the ordinary level generally applies to the application, even though the startup would have qualified on its own. This surprises collaboration teams who assume the concession travels with the partner. If fee level materially affects a joint programme, the ownership structure has to be decided before filing, not afterwards, and any later change of applicant is a transfer with its own consequences under Rule 7.
What happens when we acquire a startup with pending applications?
Two things run in parallel. The assignment itself must be in writing and duly executed under section 68, and title should be recorded with the Patent Office so the register reflects the new proprietor. Separately, because the applications were filed at the concessional level and are moving to an applicant outside those categories, the Rules require the difference between the fee levels to be paid at the time of the transfer request. Treat both as line items in the transaction plan.
Can a company get expedited examination in India?
Sometimes, but not simply by being a company. Rule 24C works through listed grounds, and the ones most often available to corporate applicants relate to the choice of India as the international searching or preliminary examining authority, eligibility under an arrangement for accelerated processing with a partner office, and applicants in sectors notified for the purpose. Grounds have been added over time. Check the current Rule, confirm the evidence you can produce, and weigh the higher official fee against the commercial value of an earlier examination report.
Do we have to report on how our Indian patents are being used?
The Act empowers the Controller to call for information from a patentee about the working of a patented invention in India, and Rule 131 prescribes the form and manner in which the required statements are furnished. For a company holding many granted patents, this is a recurring compliance task rather than a one-off. Assign it to a named owner, collect the underlying commercial information in advance, and confirm the current periodicity and format in the Rules, since these have been revised.
