Maintaining Innovation Records: The Importance of the Register of Patents

When a patent is granted in India, the inventor’s rights don’t exist in a vacuum. They need to be officially recorded, publicly accessible, and legally verifiable. This is precisely the role of the Register of Patents – a formal, structured document maintained under the Patents Act, 1970 that serves as the definitive source of truth for patent ownership, transactions, and legal status in India. Understanding this register is essential not just for exam preparation, but for anyone involved in patent commercialisation, licensing, or litigation.

What is the Register of Patents? 🔗

Under Section 67 of the Patents Act, 1970, there shall be kept at the patent office a Register of Patents, which records the names and addresses of grantees of patents; notifications of assignments, extensions, and revocations of patents; and particulars of such other matters affecting the validity or proprietorship of patents as may be prescribed.

In simple terms, the register functions as the official ledger for all patent-related activity in India. Every significant event in the life of a patent – from the moment it is granted to any change in ownership, licensing arrangement, or revocation – finds its way into this record.

The register is kept under the control and management of the Controller of Patents, subject to the superintendence and directions of the Central Government. The Controller of Patents operates under the Office of the Controller General of Patents, Designs & Trade Marks (CGPDTM), which is a subordinate office of the Department for Promotion of Industry and Internal Trade (DPIIT).

What information does the register contain? 🔗

The register is not simply a list of granted patents. It captures a range of details that collectively describe the legal status and commercial history of each patent. The key entries include:

Names and addresses of grantees: Every patent grant is recorded with the full name and address of the grantee – the person or entity to whom the patent was originally issued. This establishes the initial proprietary interest.

Assignments and transmissions: When a patent is sold or transferred to another person or company, that assignment must be recorded. Similarly, when a patent passes by transmission – such as through inheritance or operation of law – the new owner’s details are entered.

Licences and mortgages: If the patentee grants a licence to someone to use the invention, or creates a mortgage over the patent as security, those interests are also recorded. This protects both the licensor and the licensee.

Extensions and revocations: Notifications of extensions and revocations of patents are expressly required to be entered in the register.

Other prescribed particulars: Matters affecting the validity or proprietorship of patents, as may be prescribed under the Patent Rules, 2003, are also entered. This ensures the register remains a comprehensive legal record rather than a partial one.

The trust restriction: a crucial legal detail 🔗

One provision that frequently appears in examinations deserves special attention. No notice of any trust – whether express, implied, or constructive – shall be entered in the register, and the Controller shall not be affected by any such notice.

This rule has a clear practical purpose. The register deals strictly with legal ownership and recorded interests. Equitable interests arising under trusts are not the concern of the Controller. If a patentee holds a patent on trust for a beneficiary, the Controller recognises only the registered proprietor. Courts may enforce such trusts separately, but the register remains clean of such complexities. This rule prevents the Controller from being drawn into private disputes about beneficial ownership.

Requirements for valid assignments and transfers 🔗

The Act places clear conditions on how patent rights can change hands. Under Section 68, an assignment of a patent or of a share in a patent, a mortgage, licence, or the creation of any other interest in a patent shall not be valid unless the same is in writing and the agreement between the parties is reduced to the form of a document embodying all the terms and conditions governing their rights and obligations, and duly executed.

This means oral agreements to transfer patent rights have no legal standing. The written document, once executed, must then be registered to be effective against third parties.

Registering a new title or interest 🔗

Under Section 69, where any person becomes entitled by assignment, transmission, or operation of law to a patent or to a share in a patent, or becomes entitled as a mortgagee, licensee, or otherwise to any other interest in a patent, that person shall apply in writing in the prescribed manner to the Controller for the registration of their title or, as the case may be, notice of their interest in the register.

The Controller, on being satisfied with the proof of title, will then either register the person as proprietor or co-proprietor, or enter a notice of their interest along with particulars of the instrument creating it. If there is a dispute between parties regarding whether the transaction has validly vested title, the Controller may refuse to take action until the rights of the parties have been determined by a competent court.

Critically, a document in respect of which no entry has been made in the register shall not be admitted by the Controller or by any court as evidence of the title of any person to a patent or to a share or interest therein, unless the Controller or court, for reasons to be recorded in writing, otherwise directs. This gives the registration process real legal weight – an unregistered transfer is effectively invisible to the legal system in most proceedings.

Power of the registered proprietor 🔗

Under Section 70, subject to the provisions of the Act relating to co-ownership and to any rights vested in other persons of which notice is entered in the register, the person or persons registered as grantee or proprietor of a patent have the power to assign, grant licences under, or otherwise deal with the patent, and to give effectual receipts for any consideration for any such assignment, licence, or dealing.

This provision essentially means that the registered proprietor has full authority to commercially exploit the patent. Third parties transacting with a registered proprietor can rely on that registration as proof of authority. If someone’s interest is not entered in the register, they cannot hold the registered proprietor accountable for dealings that person was unaware of.

Evidentiary value of the register 🔗

One of the most practically significant features of the register is its evidentiary status in legal proceedings. Notwithstanding anything contained in the Indian Evidence Act, 1872, a certified copy of or extract from the register, certified under the hand of the Controller or any duly authorised officer, shall be admissible in evidence in all legal proceedings.

This is a special statutory provision. Ordinarily, documents need to satisfy requirements under the Evidence Act to be admitted in court. The Patents Act carves out an exception: a certified copy of the register entry is admissible as evidence of the facts recorded in it. In patent infringement suits, licence disputes, and assignment challenges, this provision allows parties to quickly establish ownership or interests without extended documentary battles.

The electronic register and public access 🔗

The Act expressly permits the Controller to keep the register of patents or any part thereof in computer floppies, diskettes, or any other electronic form, subject to prescribed safeguards. References in the Act to entries in the register, and to particulars being registered, are deemed to include records kept in electronic form.

In practice, this has materialised through the Indian Patent Advanced Search System (InPASS), the official public-facing database operated by the Indian Patent Office. The Indian Patent Office introduced InPASS for the first time in 2015. The InPASS database provides four menu tabs: Patent Search, Patent E-register, Application Status, and Help. Through the Patent E-register tab specifically, anyone can view the legal status and ownership details of a granted patent by entering the patent number.

The IP India website is available to the public free of charge. Anyone can check the details of published or granted patents, including the patent application number, publication number, filing and publication dates, title of the invention, inventor and applicant details, and the complete history of the patent.

This open-access model reflects the fundamental philosophy underlying the patent system: in exchange for a limited monopoly, inventors disclose their invention to the public. The register makes the administrative and legal record of that exchange accessible to all.

Rectification of the register 🔗

The register, like any formal record, can contain errors or outdated entries. The Act provides for correction through Section 71. Under Section 71, the Appellate Board may, on the application of any person aggrieved by the absence or omission of any entry from the register or by any incorrect entry, order rectification of the register.

This ensures that the register is not a static, inflexible document. Wrongful entries can be challenged and corrected, and legitimate interests that were improperly omitted can be added. The rectification mechanism reinforces the reliability of the register as a legal instrument.

Why the register matters for patent transactions 🔗

The Register of Patents is not administrative paperwork for its own sake. It serves several critical functions in the commercial and legal life of a patent:

Due diligence: Before acquiring a patent or entering a licensing agreement, buyers and licensees search the register to verify who the actual owner is and whether any encumbrances – such as mortgages or prior licences – already exist.

Priority of interests: Registration determines priority between competing claimants. If two parties both have agreements with a patentee but only one has registered their interest, the registered party generally has the stronger claim.

Bank financing: Lenders who accept patents as collateral require registration of the mortgage in the register to perfect their security interest. Without registration, their security may be vulnerable to subsequent claims.

Litigation support: In infringement proceedings, the plaintiff must establish standing as the registered proprietor or exclusive licensee. The register provides that proof quickly and conclusively through certified copies.

Technology transfer: For startups licensing technology from research institutions or foreign patent holders, verifying the register confirms that the licensor has the authority to grant the licence and that no conflicting licences exist.

Together, these functions make the Register of Patents a foundational institution within India’s innovation infrastructure. It does not simply record history – it actively enables and secures transactions that drive innovation forward.

What do you think? If a company acquires a patent through a valid written assignment but fails to register that assignment with the Controller, how should courts treat that company’s ownership claim when a third party later challenges it? And should the prohibition on recording trusts in the register be reconsidered in light of growing use of patent holding structures in corporate India?
