Patent assignment in India is governed by the <strong>Patents Act, 1970<\/strong>, and requires formal registration with the Patent Office within <strong>6 months<\/strong> of execution. Without registered assignment, the assignee has no legal standing to enforce the patent against infringers.<\/p>\n<\/blockquote>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Introduction<\/h2>\n\n\n\n<p>When a patent is assigned, the original patent holder (assignor) transfers ownership of all or part of the patent rights to another person or entity (assignee). This transfer may happen as part of a business sale, a startup acquisition, a technology commercialisation deal, or a settlement between co-inventors.<\/p>\n\n\n\n<p>Patent assignment in India is a formal legal process. The assignment must be in writing, signed by both parties, and recorded at the Indian Patent Office. An unregistered assignment is not enforceable against third parties and leaves the assignee without the right to sue infringers.<\/p>\n\n\n\n<p>This guide covers everything businesses and patent holders need to know about patent assignment in India: the legal framework, types of assignment, the step-by-step process, required documents, government fees, timelines, and common mistakes to avoid.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">What Is Patent Assignment?<\/h2>\n\n\n\n<p>Under Section 68 of the Patents Act, 1970, an assignment of a patent or a share in a patent must be in writing and signed by or on behalf of the parties to the transaction. Section 69 requires that the assignment be registered with the Controller of Patents.<\/p>\n\n\n\n<p>Assignment is distinct from licensing. In a <strong>licence<\/strong>, the patent owner retains ownership and merely permits the licensee to use the patent. In an <strong>assignment<\/strong>, ownership itself is transferred. The assignee steps into the shoes of the original patent holder.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"http:\/\/quickstartupindia.com\/blog\/wp-content\/uploads\/2026\/06\/patent-assignment-1024x683.png\" alt=\"patent assignment\" class=\"wp-image-3081 lazyload\" title=\"\"><noscript><img decoding=\"async\" width=\"1024\" height=\"683\" src=\"http:\/\/quickstartupindia.com\/blog\/wp-content\/uploads\/2026\/06\/patent-assignment-1024x683.png\" alt=\"patent assignment\" class=\"wp-image-3081 lazyload\" title=\"\" srcset=\"https:\/\/quickstartupindia.com\/blog\/wp-content\/uploads\/2026\/06\/patent-assignment-1024x683.png 1024w, https:\/\/quickstartupindia.com\/blog\/wp-content\/uploads\/2026\/06\/patent-assignment-300x200.png 300w, https:\/\/quickstartupindia.com\/blog\/wp-content\/uploads\/2026\/06\/patent-assignment-768x512.png 768w, https:\/\/quickstartupindia.com\/blog\/wp-content\/uploads\/2026\/06\/patent-assignment-1320x880.png 1320w, https:\/\/quickstartupindia.com\/blog\/wp-content\/uploads\/2026\/06\/patent-assignment-600x400.png 600w, https:\/\/quickstartupindia.com\/blog\/wp-content\/uploads\/2026\/06\/patent-assignment.png 1536w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/noscript><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Types of Patent Assignment in India<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Complete Assignment<\/h3>\n\n\n\n<p>All rights in the patent are transferred to the assignee, including the right to sue for infringement, the right to grant sub-licences, and the right to further assign. The assignor retains no rights in the patent.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. Partial Assignment<\/h3>\n\n\n\n<p>Only some rights in the patent are transferred. For example, the assignor may transfer rights in a specific territory or for a specific field of use, while retaining rights elsewhere. Both parties then hold independent rights in their respective portions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Assignment by Operation of Law<\/h3>\n\n\n\n<p>Patent rights may be transferred automatically under law \u2014 for example, on the death of the patent holder (to heirs or estate), on insolvency (to the official assignee), or on merger or amalgamation of a company (to the surviving entity). These transfers must still be recorded at the Patent Office.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Step-by-Step Patent Assignment Process in India<\/h2>\n\n\n\n<p><strong>Step 1: Draft the assignment agreement.<\/strong> The agreement must be in writing, identify the patent by number and title, specify the consideration (payment), define the scope of rights being transferred (complete or partial, geographic scope, field of use), and be signed by both the assignor and assignee or their authorised representatives.<\/p>\n\n\n\n<p><strong>Step 2: Execute the agreement.<\/strong> Both parties sign the assignment deed. If either party is a company, the authorised signatory must execute the deed and affix the company seal (if applicable). For foreign parties, notarisation and apostille may be required.<\/p>\n\n\n\n<p><strong>Step 3: Prepare Form 16.<\/strong> Form 16 is the prescribed Patent Office form for recording a change in ownership (application for registration of assignment). It must be filed by the assignee.<\/p>\n\n\n\n<p><strong>Step 4: Pay the prescribed government fee.<\/strong> The fee depends on whether the assignee is a natural person\/startup\/small entity or a company\/large entity.<\/p>\n\n\n\n<p><strong>Step 5: File at the Patent Office.<\/strong> The application (Form 16 + assignment agreement + fee) is filed at the jurisdictional branch of the Indian Patent Office (Mumbai, Chennai, Delhi, or Kolkata) or online through the IP India e-filing portal.<\/p>\n\n\n\n<p><strong>Step 6: Patent Office examination.<\/strong> The Controller of Patents examines the application to verify that the assignment agreement is properly executed and that the prescribed fees have been paid.<\/p>\n\n\n\n<p><strong>Step 7: Registration and update of patent register.<\/strong> On acceptance, the Patent Office records the assignee&#8217;s name as the new owner in the Register of Patents and issues a certificate of registration of title.<\/p>\n\n\n\n<p><strong>Timeline:<\/strong> Filing to registration typically takes 3 to 6 months, depending on Patent Office workload and whether any objections are raised.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Documents Required for Patent Assignment<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Patent assignment agreement (original or notarised copy)<\/li>\n\n\n\n<li>Form 16 \u2014 duly completed and signed<\/li>\n\n\n\n<li>Copy of patent grant certificate<\/li>\n\n\n\n<li>Identity proof of assignor and assignee (PAN \/ passport \/ incorporation certificate)<\/li>\n\n\n\n<li>Board resolution or power of attorney if signing on behalf of a company<\/li>\n\n\n\n<li>Proof of fee payment (challan or e-payment confirmation)<\/li>\n\n\n\n<li>Apostille \/ notarisation for foreign parties<\/li>\n\n\n\n<li>Deed of assignment if separate from the main agreement<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Government Fees for Patent Assignment (2026)<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Service<\/th><th>Natural person \/ Startup \/ Small entity<\/th><th>Company \/ Large entity<\/th><\/tr><\/thead><tbody><tr><td>Form 16 \u2014 registration of assignment<\/td><td>\u20b91,600<\/td><td>\u20b98,000<\/td><\/tr><tr><td>Each additional patent under same assignment<\/td><td>\u20b9800<\/td><td>\u20b94,000<\/td><\/tr><tr><td>Certified copy of registered assignment<\/td><td>\u20b9200 per page<\/td><td>\u20b9200 per page<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p>In addition to the Patent Office fee, there are professional fees for drafting the assignment agreement (typically \u20b910,000 to \u20b930,000 depending on complexity) and stamp duty on the assignment deed, which varies by state and is calculated on the value of the consideration.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Stamp Duty on Patent Assignment<\/h2>\n\n\n\n<p>A patent assignment deed is an instrument transferring property and is therefore subject to stamp duty under the applicable state Stamp Act or the Indian Stamp Act. Stamp duty is calculated on the consideration value stated in the assignment agreement. Rates differ by state \u2014 in Maharashtra, for example, stamp duty on a transfer of intellectual property is charged as a percentage of the consideration or market value. Failure to adequately stamp the assignment deed makes it inadmissible as evidence in court.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Can an Employer Claim Patent Assignment from an Employee?<\/h2>\n\n\n\n<p>Under Section 17 of the Patents Act, if an invention is made by an employee in the course of their normal duties or specifically assigned duties, and the nature of those duties was such that the invention was expected to result, the employer is entitled to the patent. In such cases, the employment agreement typically requires the employee to execute an assignment in favour of the employer.<\/p>\n\n\n\n<p>For inventions made outside the course of employment \u2014 using the employee&#8217;s own time and resources and not related to their employer&#8217;s business \u2014 the patent belongs to the employee, not the employer.<\/p>\n\n\n\n<p>Every employment agreement in an IP-intensive business should contain a clear IP assignment clause covering inventions and work product created during employment.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Patent Assignment in a Merger or Acquisition<\/h2>\n\n\n\n<p>When a company is acquired, merged, or demerged, all patents registered in the name of the absorbed or transferring entity must be recorded in the name of the surviving or acquiring entity at the Patent Office. This requires filing Form 16 along with a certified copy of the merger\/demerger order from the National Company Law Tribunal (NCLT).<\/p>\n\n\n\n<p>This recording is not automatic \u2014 even after the NCLT order takes effect, the Patent Office records will continue to show the old entity&#8217;s name until a formal application is filed. An acquiring company that fails to update the patent register may face difficulty enforcing the patents or licensing them to third parties.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Assignment vs Licence: Choosing the Right Structure<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Factor<\/th><th>Assignment<\/th><th>Licence<\/th><\/tr><\/thead><tbody><tr><td>Ownership transfer<\/td><td>Yes<\/td><td>No<\/td><\/tr><tr><td>Assignor retains rights<\/td><td>No (complete assignment)<\/td><td>Yes<\/td><\/tr><tr><td>Right to sue infringers<\/td><td>Assignee only<\/td><td>Usually licensor; exclusive licensee may also sue<\/td><\/tr><tr><td>Ongoing royalties<\/td><td>Optional<\/td><td>Typical<\/td><\/tr><tr><td>Reversibility<\/td><td>No (permanent)<\/td><td>Yes (on expiry or termination)<\/td><\/tr><tr><td>Patent Office registration<\/td><td>Mandatory<\/td><td>Advisable but not mandatory<\/td><\/tr><tr><td>Best for<\/td><td>Full exit, M&amp;A, startup sale<\/td><td>Commercialisation while retaining ownership<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Common Mistakes in Patent Assignment<\/h2>\n\n\n\n<p><strong>Failing to register.<\/strong> Many businesses execute an assignment agreement but never file Form 16 at the Patent Office. Under Section 69(2), an unregistered assignment is inadmissible as evidence of title in any proceeding to enforce patent rights.<\/p>\n\n\n\n<p><strong>Missing the 6-month window.<\/strong> Section 69(3) provides that if the assignment is not registered within 6 months of execution, the unregistered assignee cannot recover costs in any infringement action. File promptly after execution.<\/p>\n\n\n\n<p><strong>Inadequate assignment agreement.<\/strong> Assignments that do not clearly define the scope of rights (complete vs partial, territories, field of use) cause disputes between assignor and assignee. The agreement must be comprehensive and unambiguous.<\/p>\n\n\n\n<p><strong>Omitting related IP.<\/strong> A patent may be part of a family of related patents or pending applications. An assignment that transfers one patent but not related continuation or divisional applications may leave the assignee with incomplete protection.<\/p>\n\n\n\n<p><strong>No due diligence on encumbrances.<\/strong> A patent may be pledged as security (charged in favour of a lender) or subject to an existing licence. The assignee must conduct due diligence to identify any encumbrances before executing the assignment.<\/p>\n\n\n\n<p><strong>Insufficient stamp duty.<\/strong> An assignment deed that is not adequately stamped is inadmissible in evidence and may attract penalties. Stamp the document correctly in the state where it is executed.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n<div id=\"rank-math-faq\" class=\"rank-math-block\">\n<div class=\"rank-math-list \">\n<div id=\"faq-question-1780638218595\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What is a patent assignment in India?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>A patent assignment is the legal transfer of ownership rights in a patent from one party (the assignor) to another party (the assignee). Through an assignment, the assignee acquires all or part of the rights associated with the patent, including the right to use, license, sell, or enforce the patent.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1780638221837\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What is the process for assigning a patent in India?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The patent assignment process begins with the execution of a written assignment agreement between the assignor and assignee. The agreement should clearly identify the patent, the parties involved, and the rights being transferred. After execution, the assignee must apply to record the assignment with the Indian Patent Office by filing the prescribed forms and supporting documents.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1780638223011\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What documents are required for a patent assignment?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The key documents generally include the patent assignment deed or agreement, details of the patent being assigned, proof of ownership, identification documents of the parties, and the prescribed forms required by the Patent Office. In some cases, additional supporting documents or authorizations may be required, particularly when the assignment involves companies, foreign entities, or multiple patent owners.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1780638224291\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">Is it mandatory to register a patent assignment with the Patent Office?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>While the assignment agreement may be valid between the parties upon execution, recording the assignment with the Indian Patent Office is highly advisable. Registration creates an official record of ownership and helps establish the assignee&#8217;s rights against third parties.<\/p>\n\n<\/div>\n<\/div>\n<div id=\"faq-question-1780638226076\" class=\"rank-math-list-item\">\n<h3 class=\"rank-math-question \">What is the cost of a patent assignment in India?<\/h3>\n<div class=\"rank-math-answer \">\n\n<p>The cost of a patent assignment typically includes government filing fees, stamp duty on the assignment deed (which varies by state and transaction value), and professional fees charged by patent agents or legal professionals.<\/p>\n\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Need Help With Patent Assignment or IP Registration?<\/h2>\n\n\n\n<p>\ud83d\udfe1 <strong>Quick Startup India<\/strong>  provide complete patent registration, patent assignment drafting and filing, IP due diligence, and dispute resolution advisory for businesses and IP owners across all sectors in India.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">IP Protection Services<\/h3>\n\n\n\n<p>\ud83d\udc49 <a href=\"https:\/\/legalip.in\/patent.php\" target=\"_blank\" rel=\"noopener\">Patent Registration <\/a> \ud83d\udc49 <a href=\"https:\/\/legalip.in\/trademark-registration.php\" target=\"_blank\" rel=\"noopener\">Trademark Registration <\/a>\ud83d\udc49 <a href=\"https:\/\/legalip.in\/copyright.php\" target=\"_blank\" rel=\"noopener\">Copyright Registration<\/a> \ud83d\udc49 <a href=\"https:\/\/legalip.in\/design-registration.php\" target=\"_blank\" rel=\"noopener\">Design Registration <\/a><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Business Registration and Compliance Services<\/h3>\n\n\n\n<p>\ud83d\udc49 <a href=\"https:\/\/legaltax.in\/gst-registration.php\" target=\"_blank\" rel=\"noopener\">GST Registration and Filing <\/a> \ud83d\udc49 <a href=\"https:\/\/legaltax.in\/private-limited-company.php\" target=\"_blank\" rel=\"noopener\">Private Limited Company Registration<\/a> \ud83d\udc49 <a href=\"https:\/\/legaltax.in\/llp-registration.php\" target=\"_blank\" rel=\"noopener\">LLP Registration<\/a> \ud83d\udc49 <a href=\"https:\/\/legaltax.in\/msme-registration.php\" target=\"_blank\" rel=\"noopener\">MSME \/ Udyam Registration<\/a> \ud83d\udc49 <a href=\"https:\/\/legaltax.in\/startup-registration.php\" target=\"_blank\" rel=\"noopener\">Startup India Registration<\/a><\/p>\n\n\n\n<p><strong>Call Now: <a href=\"tel:+918595439395\">+91 8595439395<\/a><\/strong> <strong>  Free Consultation: Monday to Saturday, 9 AM to 6 PM<\/strong><\/p>\n\n\n\n<p><strong><a href=\"https:\/\/quickstartupindia.com\/#cta\">Get Started Now \u2192<\/a><\/strong><\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<p><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Views: 0 \u2696\ufe0f Did You Know?
