2 of the Patents explained: this guide covers what it means, who it applies to, the step-by-step process, documents required, fees, due dates and penalties in India — so you can stay compliant with confidence and avoid costly mistakes.
Rule 1 gives the Patents Rules, 2003 their name and says when they came into force. Rule 2 is the dictionary: it fixes what words such as "Act", "appropriate office", "article", "Form" and "request for examination" mean wherever they appear in the Rules. This article covers rule 1 and the general definitions in rule 2; the three applicant categories (educational institution, small entity and startup) have their own article.
The Rules are called the Patents Rules, 2003 and came into force on the date the Patents (Amendment) Act, 2002 came into force. Rule 2 defines the working terms of the Rules, and any word it does not define takes its meaning from the Patents Act, 1970. A "Form" always means a Form in the Second Schedule, and "request for examination" covers both ordinary and expedited examination.
Rule 1: name and start date
Rule 1 has two sub-rules and no more.
- Sub-rule (1): "These rules may be called the Patents Rules, 2003."
- Sub-rule (2): they come into force on the date on which the Patents (Amendment) Act, 2002 comes into force.
The rule does not print a calendar date. It ties the start of the Rules to the start of the amending Act. The Rules are made under the Central Government's rule-making power in section 159 of the Patents Act; see our article on sections 158-159 of the Patents Act, 1970 for that power.
The Rules have been amended many times since. The text on this page is the consolidated text up to 21 September 2021 as read with the two notified amending sets of March 2024, namely the Patents (Amendment) Rules, 2024 and the Patents (Second Amendment) Rules, 2024. Neither of them changed rule 1 or rule 2.
Rule 2: how the definitions work
Rule 2 opens with the words "In these rules, unless the context otherwise requires". That wording matters in two ways. First, a defined word has the stated meaning everywhere in the Rules. Second, if a particular rule plainly uses the word differently, the context wins. The clauses are lettered (a), (b), (c) and so on, with inserted clauses carrying letters such as (ca), (da) and (db).
If you are preparing a filing and are not sure how a term applies to you, a short conversation with a professional before you file can prevent later corrections. Our legal consultation service is set up for that.
The general definitions
| Clause | Term | What the rule says |
|---|---|---|
| (a) | "Act" | The Patents Act, 1970 (39 of 1970) |
| (b) | "appropriate office" | The appropriate office of the patent office as specified in rule 4 |
| (c) | "article" | Includes any substance or material, and any plant, machinery or apparatus, whether affixed to land or not |
| (d) | "Form" | A Form specified in the Second Schedule |
| (da) | "person other than a natural person" | Shall include a "small entity" |
| (db) | "Request for examination" | A request for examination, including expedited examination, made under section 11B in respect of rule 24B or rule 24C |
| (e) | "Schedule" | A Schedule to the Rules |
| (f) | "section" | A section of the Act |
| (g) | Undefined words | Words and expressions used but not defined in the Rules have the meanings given in the Act |
Clauses (ca), (fa) and (fb) define "educational institution", "small entity" and "startup". They sit in rule 2 but belong with the fee scale, so we deal with them in our article on small entity, startup and educational institution.
Clause by clause
"Act" and "section". Every reference to "the Act" is a reference to the Patents Act, 1970, and every reference to a "section" is to a section of that Act. A rule that says "section 8" therefore means section 8 of the Patents Act. Our guide to section 8 of the Patents Act shows how the Act and the Rules fit together for one such provision.
"Appropriate office". The definition points to rule 4, which decides which branch of the patent office handles an application or proceeding. The deciding factors are covered in our article on rules 3 and 4.
"Article". The definition is wide. It reaches a substance, a material, a plant, machinery or apparatus, and it makes no difference whether the item is fixed to land. This matters because the Rules use "article" when describing products, for example in connection with specifications and claims.
"Form". A Form is one of the Forms in the Second Schedule. A document filed in an informal letter format is therefore not a "Form" for the Rules, although rule 8 allows Form 30 where no Form is specified for a purpose (see rules 8 and 9).
"Person other than a natural person". Clause (da) says this expression "shall include a small entity". The effect is that a small entity is counted in the group of persons other than natural persons, for example where the Rules speak of an application moving from one category of applicant to another.
"Request for examination". Clause (db) is a modern, practical definition. It treats the ordinary request under rule 24B and the expedited request under rule 24C as one thing, made under section 11B. A reference to "request for examination" in the Rules (including in the refund provision of rule 7) therefore covers both. Our articles on rule 24B and rule 24C explain the two routes.
"Schedule". The Rules carry Schedules, for fees, forms, the form of patent, costs and certain international fees. The word in the Rules always means one of them.
Undefined words. Clause (g) is the safety net. If a word such as "invention", "patentee" or "Controller" is not defined in the Rules, the Patents Act meaning applies. The Act definitions are taken up in our articles on section 2 (inventive step and industrial application), section 2 (patentee, assignee, Controller and Patent Office) and section 2 (Convention, PCT, priority date).
A worked example
Anaya Pharma Tools LLP files a patent application and wants to know whether "Form" covers the covering letter its agent sends. Under clause (d), a "Form" is only a Form in the Second Schedule, so the covering letter is not a Form. When the same firm later asks whether its request for expedited examination counts as a "request for examination", clause (db) answers: yes, because the definition expressly includes expedited examination made under rule 24C.
Where the definitions are used
| Defined term | Where you will meet it |
|---|---|
| Appropriate office | Rule 4 and every filing that must be made at a particular office |
| Form | Rule 8 and the Second Schedule |
| Request for examination | Rules 24B and 24C, and the refund rule in rule 7(4A) |
| Person other than a natural person | The fee scale and rule 7(3) |
| Undefined words | Any rule that uses a word taken from the Act |
Need help with reading the Rules?
Definitions look small, yet a wrong assumption about a term such as "request for examination" or "appropriate office" can send a filing down the wrong route.
