Section 1 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.
Section 1 does three small but necessary jobs. It gives the Act its name, says where it applies, and leaves the date of commencement to the Central Government, which may bring different provisions into force on different dates. Anyone reading the Act for the first time, or checking when a particular rule began to apply, starts here, and if the date of a particular provision matters to a live matter, a legal consultation is the safer route.
The Act is called the Patents Act, 1970. It extends to the whole of India. It comes into force on such date as the Central Government appoints by notification in the Official Gazette, and different dates may be appointed for different provisions. A reference to "the commencement of this Act" inside any provision means the date that provision came into force.
What section 1 says, sub-section by sub-section
Sub-section (1) - short title. "This Act may be called the Patents Act, 1970." The Act is Act No. 39 of 1970, and every later amendment is read into this same Act. The consolidated text we use is already amended by the Patents (Amendment) Acts of 1999, 2002 and 2005, the Tribunals Reforms Act, 2021 and the Jan Vishwas (Amendment of Provisions) Act, 2023. For a plain-language overview of the whole statute, see our complete guide to the Patents Act, 1970.
Sub-section (2) - extent. "It extends to the whole of India." There is no carve-out for any State or Union territory in this sub-section, and no list of exceptions. A patent granted under the Act is therefore a single national right, not a collection of State rights. The Act itself says nothing about patents outside India; protection abroad depends on the law of each country.
Sub-section (3) - commencement. "It shall come into force on such date as the Central Government may, by notification in the Official Gazette, appoint." The Act did not begin on the day it was passed. It waited for a notification.
The proviso. "Provided that different dates may be appointed for different provisions of this Act, and any reference in any such provision to the commencement of this Act shall be construed as a reference to the coming into force of that provision." Two things follow:
- The Government could bring the Act into force in parts.
- Where a section counts time from "the commencement of this Act", that count starts from the date that particular section began to operate, not from some single date for the whole Act.
The dates in the footnote
The printed text carries a footnote on the words "such date". It records two notifications:
| Notification | Date of effect | Provisions covered |
|---|---|---|
| S.O. 300 dated 20-4-1972 | 20-4-1972 | All provisions except sub-section (2) of section 12, sub-section (2) of section 13, section 28, section 68 and sections 125 to 132 |
| S.O. 799 dated 10-3-1978 | 1-4-1978 | Sub-section (2) of section 12, sub-section (2) of section 13, section 28, section 68 and sections 125 to 132 |
The footnote also points to the Gazette of India, Part II, Section 3(ii), as the place where both notifications were published.
In plain terms, most of the Act began on 20 April 1972. A small group of provisions waited until 1 April 1978. Those provisions are scattered: two sub-sections on examination and search (sections 12 and 13), the inventor-related section 28, the assignment-related section 68, and the whole body of rules on patent agents in sections 125 to 132. We explain each of them in its own article in this series.
Later amendments are different. The footnote deals only with the original Act. Each amending Act has its own commencement. The footnotes in the consolidated text show, for example, changes from 20-5-2003 (the 2002 Amendment Act), 1-1-2005 (the 2005 Amendment Act), 4-4-2021 (the Tribunals Reforms Act, 2021) and 1-8-2024 (the Jan Vishwas Act, 2023, as far as the Patents Act is concerned). When you read any section, read its footnotes, because a number in brackets tells you that the wording has been replaced and from when.
Why a staged commencement matters in practice
A staged start sounds like a historical detail, but it still affects how you read the Act.
- Dating a provision. If a question turns on whether a provision applied at a given time, the answer is found in the commencement notification and in the amending Act's own date, not in section 1 alone.
- References to "commencement". The proviso tells you not to assume one single start date for the whole statute.
- Reading old documents. Older patents and older literature may describe rules that have since been replaced. The footnotes are the quickest way to see what was substituted and when.
Example. Meera, an engineer at a small tools company, is reading a 1990s journal article that says patents can be granted only for methods of manufacture in certain fields. She checks the Act and finds that the corresponding provision, section 5, now appears only as an entry saying it was omitted by the Patents (Amendment) Act, 2005 with effect from 1-1-2005. She concludes that the article describes law that no longer applies. Section 1 did not tell her that; the footnote did. Section 1 only told her that provisions of this Act can start and change on different dates.
What the section does not say
- It does not state a single commencement date for the whole Act; the date is by notification.
- It does not list the provisions in force on each date; the footnote does.
- It does not define any term. Definitions are in section 2, which we cover in our three-part series on the definitions.
- It does not say anything about the Patents Rules, 2003, which are made under the Act and are not part of the sources used here.
- It does not say anything about the Jan Vishwas (Amendment of Provisions) Act, 2026. That Act amends other provisions of the Patents Act and its own section 1(2) leaves its commencement to a Central Government notification, which we have not seen; section 1 of the Patents Act is not touched by it.
How the chapters are laid out
Section 1 sits in Chapter I (Preliminary), together with section 2. Chapter II covers inventions that are not patentable, and Chapter III begins the rules on applying for a patent. If you want to follow the life of a patent from idea to grant, our patent registration process guide walks through it, and this section-wise series then explains each step against the text of the Act.
