Section 161 of the Patents Act, 1970
Special provisions with respect to certain applications deemed to have been refused under Act 2 of 1911
Section 161 was a transitional provision for old applications treated as refused under the 1911 law; it has since been omitted.
Official legal text
The number is still shown because Indian statutes are not renumbered when something is taken out. The provision is simply marked as omitted. Documents created before the change, including granted patents and decided cases, continue to cite it, so the reference has to remain understandable.
Nothing here replaces the statute. The official wording of the provision, together with any Gazette notification that applies to it, governs. This page only explains that material in ordinary language.
What this section says, in plain language
When the Patents Act, 1970 replaced the patent portions of the Indian Patents and Designs Act, 1911, a large number of applications were caught in mid-flight. Some of them had already been treated as refused under the old law because a step had not been completed in time. Section 161 was one of several transitional provisions written to deal fairly with that backlog. It made special arrangements for those particular applications, so that the switch from the 1911 regime to the 1970 regime did not simply extinguish rights that applicants had been pursuing in good faith.
A transitional provision has a short working life by design. Once every 1911-era application had been finally disposed of, Section 161 had nothing left to operate on. Parliament later removed it as part of the tidying up of spent provisions in the Act during the amendment rounds that modernised Indian patent law around the turn of the century. Its omission changed nothing for present-day applicants, because no application filed under the 1911 Act remains pending. Readers looking at the position of pre-1970 rights today should look instead at the repeal and savings provision of the Act, which is what still carries legal effect.
Why this section matters
Legal historians, researchers and anyone reading an old commentary or judgment that refers to this section.
Only when interpreting the transition from the 1911 Act to the 1970 Act, which is now of historical interest.
Nothing today. While it was in force it created a limited transitional route for certain applications deemed refused under the 1911 Act.
There is no practical consequence, but citing an omitted section in a live matter damages credibility.
How it works in practice
A student meets a section that no longer exists
Rohit Menon, a law student at a university in Hyderabad, is writing a dissertation on the history of Indian patent law. He finds a 1970s commentary that discusses Section 161 at length and assumes it is still part of the Act. When he opens the current bare Act he finds the section marked as omitted. His supervisor explains that the section was a bridge, not a permanent feature. It existed to handle applications that had been deemed refused under the Indian Patents and Designs Act, 1911 at the moment the 1970 Act took over, and it lost all purpose once those files were closed. Rohit rewrites the chapter to treat Section 161 as part of the transition story and cites the repeal and savings provision for the rules that still govern rights carried over from the old law. His examiner marks the correction as a sign of careful statutory reading.

Key points to remember
- Section 161 was a transitional provision about applications deemed refused under the Indian Patents and Designs Act, 1911.
- It has been omitted from the Patents Act, 1970 and has no effect today.
- For the position of rights carried over from the 1911 law, read the repeal and savings provision of the Act instead.
Connected provisions
You will find the related rules grouped below rather than inside the explanation. The separation is deliberate. The Act and the Rules are distinct legal instruments, and mixing them can lead a reader to attribute a procedural requirement to the statute itself.
Forms, deadlines and fees
Fees are prescribed in the First Schedule to the Patents Rules. Because the Schedule is revised from time to time, and charges different amounts to different categories of applicant and for physical as against electronic filing, this page describes the fee without stating a figure.

Questions people ask about Section 161
Is Section 161 of the Patents Act still in force?
No. It has been omitted from the Act. Current printings of the Patents Act, 1970 show the section number with a note that it stands omitted. It was a transitional measure connected with applications that had been treated as refused under the Indian Patents and Designs Act, 1911, and it became spent once those matters were finally dealt with. Nothing in present-day patent filing or prosecution depends on it, and it should not be cited as live law in any proceeding before the Controller or a court.
Where should I look instead for the effect of the old 1911 patent law?
Look at the repeal and savings provision of the Patents Act, 1970, which repealed the 1911 Act so far as it related to patents while preserving things lawfully done under it. That provision is the one that still explains how pre-1970 patents, registrations and proceedings were carried forward. For the designs side of the 1911 Act, the relevant modern statute is the Designs Act, 2000. If you are researching a very old right, the safest course is to read the savings language together with the record held by the Patent Office.
