  8. How this is examined
Cases checked to exist. Read the judgment before quoting a holding.

Every case cited here has been checked to exist — the citation resolves and names the right parties. The propositions attributed to each case have not been verified line by line against the judgment. Case names link through to the full judgment: read it before quoting a holding in an examination answer, and never carry a proposition from notes into court on trust.

Registration is not compulsory. Nothing in the Trade Marks Act obliges a trader to register. An unregistered mark cannot be infringed (section 27(1)), but its owner keeps the common law action for passing off (section 27(2)). That one section answers the question “Is registration of trade mark compulsory in India?” and leads straight into passing off.

1. Is registration compulsory?

No. A trader may use an unregistered mark (often marked ™) and acquire rights in it by use. But registration gives substantial advantages, which is why it is advisable:

2. Passing off

Passing off is a tort: no man may sell his goods as those of another. In Reckitt & Colman Products Ltd. v. Borden Inc. (House of Lords, 1990), the “Jif Lemon” case, Lord Oliver stated the “classical trinity” the plaintiff must prove:

In Laxmikant V. Patel v. Chetanbhai Shah, 2001 INSC 594, (2002) 3 SCC 65, the plaintiff had run a colour lab under the name “Muktajivan Colour Lab and Studio” in Ahmedabad for years; the defendant opened “Muktajivan Colour Lab and Studio” nearby. The Supreme Court held that passing off protects trade names as well as marks, that the defendant’s intention is not essential, and that where the plaintiff shows a prima facie case of passing off an interim injunction should ordinarily follow. It granted the injunction.

3. Infringement and passing off distinguished

The distinction was drawn in Kaviraj Pandit Durga Dutt Sharma v. Navaratna Pharmaceutical Laboratories, 1964 INSC 221, AIR 1965 SC 980.

Both may be joined in one suit, and the reliefs in section 135 apply to both (injunction, damages or account of profits, delivery-up). Section 134(1)(c) requires a passing off suit based on a mark to be filed in a court not inferior to a District Court.

4. Domain names

Passing off is also the main protection for domain names, since no Indian statute deals with them. In Satyam Infoway Ltd. v. Sifynet Solutions Pvt. Ltd., 2004 INSC 368, (2004) 6 SCC 145, the Supreme Court held that a domain name has all the characteristics of a trade mark and may be protected by an action for passing off; it restrained the use of “siffynet” against the prior user of “sify”. The topic is covered in detail in Unit III.

5. Assignment and transmission: sections 37 to 45

6. Rectification of the register

7. Offences and penalties: Chapter XII

How this is examined

January 2026: “Is registration of Trade Mark compulsory in India? Explain the consequences of passing off.” February 2025: a short note on “Passing Off”. For the essay, section 1 then sections 2 and 3, ending with the reliefs in section 135. For the short note, the trinity, Laxmikant Patel and the Durga Dutt distinction. Assignment, rectification and offences appear less often but are in the syllabus and make good short notes.
