Section 2 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 2(1) is the dictionary of the Act, and it is long. This is the first of three articles on it. Here we cover the clauses that decide what the law treats as an "invention": clauses (ac), (j), (ja), (l), (la), (m) and (ta). If your idea does not meet these definitions, the rest of the Act never reaches it, so it pays to read them closely before you pay for a patent drafting and filing exercise.
An invention is "a new product or process involving an inventive step and capable of industrial application". An inventive step is a feature that involves technical advance, or economic significance, or both, and makes the invention not obvious to a person skilled in the art. Capable of industrial application means capable of being made or used in an industry. New means not anticipated before the date of filing of the application with complete specification.
How section 2 is split across three articles
Section 2(1) opens "In this Act, unless the context otherwise requires,". Its clauses are listed in alphabetical order of the term. We have divided them as follows.
Two clauses are gone. Clause (a), which defined "Appellate Board", was omitted by the Tribunals Reforms Act, 2021 with effect from 4-4-2021. Clause (g) was omitted by the Patents (Amendment) Act, 2005 with effect from 1-1-2005. In the printed text each appears only as a row of asterisks and a footnote.
Clause (j): "invention"
The text reads: "invention" means a new product or process involving an inventive step and capable of industrial application."
Break that into four tests:
- A product or process. The subject is something made or a way of doing something.
- New. Defined in clause (l), below.
- Involving an inventive step. Defined in clause (ja).
- Capable of industrial application. Defined in clause (ac).
All four must be present. Clause (j) was substituted by the Patents (Amendment) Act, 2002 with effect from 20-5-2003. Section 3 then lists things that are "not inventions", even if they otherwise look like one; our post on what cannot be patented under section 3 covers that list, and section 4 separately bars patents on certain atomic energy inventions. Neither is repeated here.
Clause (ja): "inventive step"
"“inventive step” means a feature of an invention that involves technical advance as compared to the existing knowledge or having economic significance or both and that makes the invention not obvious to a person skilled in the art."
The structure is:
- A feature of the invention that involves technical advance as compared to the existing knowledge, or has economic significance, or both; and
- that feature makes the invention not obvious to a person skilled in the art.
The second limb is not optional. A technical advance or economic significance alone is not enough if the invention would be obvious to a skilled person. The Act does not describe who the "person skilled in the art" is, and it does not say how much existing knowledge counts. We state only what is printed. This clause was substituted by the 2005 Amendment Act with effect from 1-1-2005.
Drafting slip to note. The printed clauses (j) and (ja) carry a doubled closing bracket after (ja), an artefact of the substitution notes. It does not change the meaning.
Clause (ac): "capable of industrial application"
"“capable of industrial application”, in relation to an invention, means that the invention is capable of being made or used in an industry."
The test is "capable of being made or used". It is enough that the invention can be made in an industry or used in one; it need not already be in commercial production. The word "industry" is not defined in the Act. (The printed clause (ac) also ends with a stray closing bracket, again an editorial artefact.)
Clause (l): "new invention"
"“new invention” means any invention or technology which has not been anticipated by publication in any document or used in the country or elsewhere in the world before the date of filing of patent application with complete specification, i.e., the subject matter has not fallen in public domain or that it does not form part of the state of the art."
Read it in parts:
| Part of the text | What it means |
|---|---|
| "not been anticipated by publication in any document" | No earlier document, anywhere, discloses it |
| "or used in the country or elsewhere in the world" | No earlier use, in India or abroad |
| "before the date of filing of patent application with complete specification" | The cut-off is the filing date of the application with complete specification |
| "has not fallen in public domain ... does not form part of the state of the art" | Restates the test in plain words |
The wording "document" and "used" is broad and has a world-wide reach. The clause itself does not mention priority dates or grace periods; those are dealt with in sections 11, 29 to 34 and elsewhere, which we cover in later articles. Substituted by the 2005 Amendment Act with effect from 1-1-2005.
Example. Anita's company, Brightwell Appliances, develops a rice cooker with a new sensor arrangement. Before she files, an overseas engineering journal published a drawing showing the same sensor arrangement. Whatever the commercial value of her cooker, the invention has been "anticipated by publication in any document" before her filing date, so it is not a "new invention" under clause (l).
Clause (la): "Opposition Board"
"“Opposition Board” means an Opposition Board constituted under sub-section (3) of section 25". This is only a pointer. The constitution and role of the Board are in section 25, which already has its own articles on our site on pre-grant opposition under section 25(1) and post-grant opposition under section 25(2).
Clause (m): "patent"
"“patent” means a patent for any invention granted under this Act". Two points follow. A patent exists only for an "invention" in the clause (j) sense, and only if granted under this Act. An application is not a patent; a pending applicant has no patent until grant.
Clause (ta): "pharmaceutical substance"
"“pharmaceutical substance” means any new entity involving one or more inventive steps". It was inserted by the 2005 Amendment Act with effect from 1-1-2005. The text does not say more. It ties the term to "new entity" and "inventive steps", the same idea as the definition of invention. How pharmaceutical substances are treated in the rest of the Act appears in the provisions that use the term; see also our post on section 3(d) and pharma patents.
Putting the definitions together
A quick check for an idea you are thinking of patenting:
- Is it a product or a process?
- Has anything like it been published or used anywhere before your filing date with complete specification? If yes, it is not "new".
- Does it have a feature showing technical advance, economic significance or both?
- Would that feature still leave it obvious to a person skilled in the art? If yes, there is no inventive step.
- Can it be made or used in an industry?
- Is it excluded by section 3 or section 4?
Example. Dev Kumar, a materials engineer at a fictional firm, Kestrel Polymers, designs a biodegradable packaging film. A literature search finds no earlier publication or use anywhere (new). The film resists moisture noticeably better than known films (technical advance), and a skilled film chemist would not have arrived at it by routine steps (not obvious). It can be made on an existing extrusion line (capable of industrial application). Each clause is met on these invented facts; whether section 3 or any other bar applies is a separate question.

Key takeaways
- An invention is a new product or process involving an inventive step and capable of industrial application (clause (j)).
- Inventive step needs a technical advance or economic significance, and non-obviousness to a person skilled in the art (clause (ja)).
- "Capable of industrial application" means capable of being made or used in an industry (clause (ac)).
- "New" is judged against publication or use anywhere in the world before the date of filing with complete specification (clause (l)).
- Clauses (a) and (g) of section 2(1) are omitted.
