Legal documents, registry notices, and contracts are full of terms that sound familiar but carry specific meanings. This glossary explains the words you are most likely to meet when protecting a brand, an invention, or creative work, or when signing business agreements in India. Each entry goes beyond a one-line definition to explain why the concept matters in practice, with plain-language examples where they help.
A trademark is a sign — a word, logo, phrase, shape, colour combination, or a mix of these — that tells customers which business a product or service comes from. Its job is to distinguish your goods or services from everyone else's, so the strongest trademarks are distinctive rather than descriptive. For example, a made-up word used for shoes is far easier to protect than the word "Comfortable Shoes", which simply describes the product. In India, trademarks are governed by the Trade Marks Act, 1999, and a registered mark gives its owner the exclusive right to use it for the goods or services it is registered for, and to take action against confusingly similar use.
A patent is an exclusive right granted by the government for an invention that is new, involves an inventive step (it is not obvious to someone skilled in the field), and is capable of industrial application. In exchange for this protection, the inventor must publicly disclose how the invention works in the patent document. The right lasts for a limited period, after which the invention enters the public domain and anyone may use it. Founders should be especially careful about timing: publicly revealing an invention before filing — in a demo, pitch, or article — can damage its novelty and make it harder or impossible to patent.
Copyright protects original creative expression — literary works (including software code), artistic works, music, films, sound recordings, and similar creations — against unauthorised copying, adaptation, and distribution. It protects the expression of an idea, not the idea itself: two people can write different books about the same plot concept, but neither may copy the other's actual text. Copyright arises automatically when an original work is created, although registration provides valuable evidence of ownership if a dispute arises. For businesses, the key practical question is usually who owns the copyright in work created by employees, freelancers, or agencies, which should be addressed clearly in contracts.
An assignment is the transfer of ownership of an intellectual property right — such as a trademark, patent, or copyright — from one party (the assignor) to another (the assignee). Once assigned, the new owner holds the rights and can use, license, enforce, or further transfer them. Assignments are common when a founder transfers a brand they registered personally into their company, or when a business buys another business's IP. To be effective and enforceable, an assignment should be in writing, and for registered rights it is generally important to record the change of ownership with the relevant registry.
Licensing is permission granted by an IP owner (the licensor) to another party (the licensee) to use the IP under agreed conditions, without transferring ownership. A licence can be exclusive or non-exclusive, limited to certain territories, products, or time periods, and may involve royalties or a flat fee. Imagine a hypothetical coffee brand that lets a regional partner sell merchandise under its logo: the brand still owns the trademark, but the partner has a contractual right to use it within defined limits. A well-drafted licence also sets quality standards, because an owner who lets others use a mark without any control can weaken the mark itself.
Infringement is the unauthorised use of someone else's protected intellectual property — such as a registered trademark, patented invention, or copyrighted work — in a way the law prohibits. In trademark law, infringement typically involves using an identical or deceptively similar mark for related goods or services in a way that is likely to confuse the public. In copyright, it usually involves copying a substantial part of a protected work. The owner of the right can seek remedies such as an injunction to stop the use, damages or an account of profits, and in some cases the delivery-up or destruction of infringing goods.
An opposition is a formal challenge filed by a third party against a trademark application after it has been accepted and advertised in the Trade Marks Journal, but before registration is granted. Anyone who believes the mark should not be registered — often an existing brand owner who thinks the new mark is too similar to theirs — can file a notice of opposition within the prescribed period. The applicant then files a counter-statement, both sides may submit evidence, and the matter is decided after a hearing. Opposition proceedings are one of the main reasons it is worth searching for conflicting marks before filing.
An objection is a concern or refusal raised by a Trade Marks Registry examiner while examining an application, and it is set out in the examination report. Common grounds include the mark being descriptive or lacking distinctiveness, or being similar to an earlier mark already on the register. An objection is not a final rejection: the applicant can file a written reply explaining why the mark should proceed, supported by arguments or evidence of use, and may request a hearing. Ignoring an objection, however, can lead to the application being treated as abandoned, so responding properly and on time matters.
A Non-Disclosure Agreement is a contract in which one or more parties agree to keep specified information confidential and not disclose or misuse it. NDAs are used when sharing business plans with potential partners, product details with manufacturers, or technical information with developers. A useful NDA clearly defines what counts as confidential information, what the recipient may use it for, how long the obligation lasts, and what exclusions apply (for example, information already public). An NDA is not a substitute for registering IP, but it is an important tool for protecting ideas and trade secrets during early conversations.
An indemnity is a contractual promise by one party to compensate another for specified losses, damages, or liabilities — often those arising from third-party claims. For instance, in a hypothetical software development contract, the developer might indemnify the client if the delivered code turns out to infringe someone else's copyright. Indemnity clauses shift risk between parties, so their wording matters a great deal: what triggers the indemnity, whether it is capped, and what procedure applies when a claim arises. Founders should read indemnity clauses carefully, as broad, uncapped indemnities can expose a business to significant liability.
Jurisdiction is the authority of a particular court, tribunal, or legal body to hear and decide a case. It can be defined by geography (which city's or country's courts), by subject matter (such as commercial or IP disputes), or by the value of the claim. Contracts often contain a jurisdiction clause specifying which courts will handle any disputes, which can make a real practical difference to cost and convenience. In IP matters, questions of jurisdiction can also affect where an infringement suit may be filed.
Compliance means conforming to the laws, regulations, and standards that apply to a business or activity. For a company, this can include registrations, periodic filings, tax obligations, labour law requirements, and sector-specific rules. Compliance is often invisible when done well and very visible when neglected — missed filings can lead to penalties and can surface as red flags when a business seeks investment or is being acquired. Building simple routines and keeping organised records early is usually far easier than catching up later.
Due diligence is a thorough review of the legal, financial, or operational aspects of a business or transaction before proceeding with it. Investors conduct due diligence before funding a startup, and buyers do so before acquiring a business or its assets. In the IP context, due diligence checks whether the company actually owns its brand, code, and content, whether its trademarks are registered in the right name and classes, and whether there are pending disputes. Gaps discovered at this stage can delay or reshape a deal, which is why getting ownership right early is so valuable.
A trademark search is a check of the trademark register (and often the wider marketplace) to find existing marks that are identical or similar to the one you want to use. It is ideally done before you finalise a brand name, print packaging, or build a website around it. A good search looks not only for exact matches but also for marks that sound alike, look alike, or carry a similar meaning in the same or related classes. While no search can eliminate all risk, it significantly reduces the chance of objections, oppositions, or an infringement claim later.
The Nice Classification is an international system for grouping goods and services into classes for trademark registration, and India follows it. It contains 45 classes: classes 1 to 34 cover goods, and classes 35 to 45 cover services. When you apply for a trademark, you must specify the classes and the goods or services within them, and your protection generally extends only to those. For example, a hypothetical brand that sells clothing and also runs a retail store may need to consider both a goods class and a services class.
The examination report is the document issued by the Trade Marks Registry after an examiner reviews a trademark application. It records whether the examiner has any objections — on absolute grounds, such as lack of distinctiveness, or relative grounds, such as conflict with an earlier mark. If the report raises objections, the applicant must respond with a reply addressing each point. If there are no objections, or the reply is accepted, the application can move towards advertisement in the Trade Marks Journal.
The Trade Marks Journal is the official publication in which accepted trademark applications are advertised to the public. Publication gives third parties notice of the proposed registration and an opportunity to oppose it if they believe it conflicts with their rights. For brand owners, the Journal is also a useful monitoring tool: keeping an eye on it helps you spot newly advertised marks that may be similar to yours while there is still time to oppose. This is the principle behind trademark watch services.
Trademark renewal is the process of extending the life of a registered trademark. Under the Trade Marks Act, 1999, a registered trademark in India is valid for 10 years from the date of application and can be renewed indefinitely for further 10-year periods. This means a mark can, in principle, be protected for as long as the business keeps renewing it. Failing to renew can lead to the mark being removed from the register, which can weaken the owner's position and make it harder to act against copycats, so tracking renewal dates is an important part of brand management.
A well-known trademark is a mark that has become so widely recognised by the relevant section of the public that using it on unrelated goods or services would likely be taken as indicating a connection with the original owner. Indian law gives well-known marks broader protection than ordinary marks, potentially extending across classes rather than only to the goods or services for which they are registered. Recognition can come through a court decision or a determination by the Trade Marks Registry, based on factors such as the extent of public knowledge, duration and area of use, and history of enforcement. It is a status earned through reputation, not something a new brand can simply claim.
Trade dress refers to the overall look and feel of a product or its packaging — the combination of shape, colour scheme, layout, graphics, and design elements that customers associate with a particular source. Imagine a hypothetical juice brand whose bottles have a distinctive shape and a recognisable colour-band label: even without reading the name, customers might identify the product. Where trade dress has become distinctive, copying it closely can amount to passing off, and certain elements such as shapes and colour combinations may also be registrable as trademarks. Businesses entering a market should avoid imitating a competitor's packaging even if the brand name is different.
Common law rights in a trademark arise from actual use of a mark in the course of trade, rather than from registration. If a business has used a name consistently and built goodwill with customers, it may be able to stop others from misrepresenting their goods as its own through an action for passing off, even without a registration. However, these rights are generally harder and costlier to prove, because the owner must establish goodwill, misrepresentation, and damage. Registration provides statutory rights that are clearer and easier to enforce, which is why relying only on common law rights is rarely the best long-term strategy.
Passing off is a legal action that protects the goodwill of an unregistered (or registered) brand against someone who misrepresents their goods or services as being connected with it. To succeed, the claimant typically needs to show three things: goodwill attached to their brand, a misrepresentation by the other party likely to deceive the public, and resulting damage or likely damage. It is the main remedy available to owners of unregistered marks. Because it depends heavily on evidence of reputation, it is usually more complex to pursue than an infringement action based on a registered trademark.
A cease and desist letter is a formal written demand asking a person or business to stop an activity — such as using a similar trademark, copying content, or selling infringing products — and often to refrain from repeating it. It is usually the first step in an IP dispute and is sent before any court proceedings begin. A well-prepared letter identifies the rights being asserted, describes the objectionable conduct, and sets out what the sender wants done. If you receive one, it should be taken seriously but not panicked over: the claims may or may not be valid, and it is wise to seek advice before responding.
Prior art is any evidence that an invention, or something very close to it, was already known to the public before a patent application was filed. It can include earlier patents, published research papers, products on the market, public presentations, and even online videos or blog posts. Patent examiners compare an application against prior art to decide whether the invention is new and involves an inventive step. For inventors, a prior-art search before filing helps assess whether pursuing a patent is worthwhile and how to frame the claims.
