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.
1. Background
By the late nineteenth century inventors were reluctant to exhibit at international exhibitions, such as the Vienna exhibition of 1873, because their inventions could be copied abroad and their own later applications there defeated for lack of novelty. Diplomatic conferences led to the Paris Convention for the Protection of Industrial Property, signed on 20 March 1883, the first major international IP treaty. It was revised at Brussels (1900), Washington (1911), The Hague (1925), London (1934), Lisbon (1958) and Stockholm (1967), and amended in 1979. The members form the Paris Union; the Convention is administered by WIPO. India acceded in 1998, with effect from 7 December 1998. Nearly every country is now a member, and Article 2.1 of TRIPS requires WTO members to comply with its substantive articles.
2. Scope
Industrial property is understood in the broadest sense and covers patents, utility models, industrial designs, trade marks, service marks, trade names, indications of source or appellations of origin, and the repression of unfair competition; it applies to agriculture and extractive industries and to all manufactured or natural products (Article 1).
3. National treatment: Article 2
Nationals of each member country enjoy in all other member countries the same protection, and the same legal remedy against infringement, as those countries give their own nationals, without any requirement of domicile or establishment. Nationals of non-members who are domiciled or have a real and effective industrial or commercial establishment in a member country are treated as nationals (Article 3). There is no requirement of reciprocity.
4. Right of priority: Article 4
A person who has duly filed an application for a patent, utility model, design or trade mark in one member country enjoys, for filing in other member countries, a right of priority for a period of:
- twelve months for patents and utility models; and
- six months for industrial designs and trade marks,
counted from the date of the first filing. A later application filed within that period is treated as if filed on the first date, so it is not defeated by any act in between, such as publication, another person’s application or use of the invention. The applicant thus has time to decide in which countries protection is worth having, to translate and to appoint agents. Multiple and partial priorities are allowed.
India gives effect to this through convention applications: sections 133 to 139 of the Patents Act (application within twelve months of the first application in a convention country) and section 154 of the Trade Marks Act (six months).
5. Independence of rights
- Patents (Article 4bis). Patents granted in different countries for the same invention are independent of each other: refusal, revocation or expiry in one country does not affect the patent in another.
- Marks (Article 6). Conditions for filing and registration are determined by each country’s law; a mark duly registered in one country is independent of marks registered in others, including the country of origin.
6. Common rules
- Inventor’s right to be named in the patent (Article 4ter).
- Sale restricted by law is not a ground to refuse or invalidate a patent (Article 4quater).
- Importation and compulsory licences (Article 5A). Importation by the patentee of articles made abroad does not cause forfeiture. Each country may provide compulsory licences to prevent abuses such as failure to work, but not before four years from filing or three years from grant, whichever is later; forfeiture is allowed only if compulsory licences have proved insufficient. Section 84 of the Indian Act (three years from grant) reflects this.
- Grace period of at least six months for payment of maintenance fees (Article 5bis).
- Use of marks: registration may be cancelled for non-use only after a reasonable period and if the owner cannot justify inaction (Article 5C).
- Well-known marks (Article 6bis). Members must refuse or cancel registration, and prohibit use, of a mark that is a reproduction, imitation or translation liable to create confusion with a mark considered well known in that country as belonging to a person entitled to the Convention’s benefits. Sections 11(2) and 11(6) to (10) of the Trade Marks Act implement it.
- State emblems (Article 6ter). Armorial bearings, flags, official signs and emblems of states and intergovernmental organisations may not be registered as marks.
- Assignment of marks (Article 6quater) and “telle quelle” (Article 6quinquies): a mark duly registered in the country of origin must be accepted for filing and protected “as is” in other countries, subject to listed exceptions.
- Service marks must be protected (Article 6sexies), and an agent may not register his principal’s mark without authorisation (Article 6septies).
- Trade names are protected in all member countries without registration (Article 8).
- Seizure on importation of goods bearing unlawful marks or trade names, and false indications of source (Articles 9 and 10).
- Unfair competition (Article 10bis). Members must assure effective protection against any act of competition contrary to honest practices in industrial or commercial matters, in particular acts creating confusion, false allegations discrediting a competitor, and misleading indications. Section 22 of the GI Act copies this language.
- Temporary protection at official international exhibitions (Article 11); each member must set up a special industrial property service and a central office (Article 12).
7. Administrative provisions
The Union has an Assembly of members, an Executive Committee and the International Bureau (WIPO) as secretariat (Articles 13 to 15). Members may make special agreements among themselves not contravening the Convention (Article 19); the Madrid Agreement and the PCT were made under it. Disputes may be taken to the International Court of Justice (Article 28), though this has not been used and many states have reserved it. The weakness of enforcement under Paris was one reason for TRIPS, which brings its rules under WTO dispute settlement.
How this is examined
February 2025: “Explain the provisions of Paris Convention.” August 2024: “Discuss salient features of ‘Paris agreement’” (the industrial property convention is meant, not the 2015 climate agreement). January 2026: a note to “Enlist common principles under Paris Convention”. For the essay, background, then sections 3 to 6; for the note, the three principles with a list of the common rules. Always add the Indian provisions that implement each principle: they show the examiner why the Convention matters.
