Rules to be placed before Parliament
Section 160 requires every rule made under the Patents Act to be laid before both Houses of Parliament, which may change or cancel it.
Official legal text

Until that check is complete for this page, read the exact wording directly from the official source linked below — it is the only version that governs.
The authority is the enacted text, not this page. Where our wording and the official provision, or an applicable Gazette notification, do not match, the official material prevails.
What this section says, in plain language
Section 159 hands the government a wide power to make rules. Section 160 is the check on that power. It requires every rule made under the Act to be placed before each House of Parliament after it is made, so that elected representatives can see what has been done in their name.
The mechanism is the one Indian statutes use for most delegated legislation. The rule is laid before each House while it is in session, for a total of thirty days, which may be spread over one session or two or more successive sessions. During that period either House may agree that the rule should be modified, or that it should not be made at all.
If both Houses agree on a modification, the rule takes effect only in its modified form from then on. If both Houses agree that the rule should not be made, it stops having effect from then on. Importantly, this operates for the future only. Anything already lawfully done under the rule before the change stays valid. An applicant who filed a form under a rule that Parliament later annulled does not lose the benefit of that filing.
In practice Parliament rarely disturbs patent rules. The value of the section is preventive rather than corrective. Because the government knows every amendment will be tabled, rules are drafted carefully, and the consultation that precedes them is taken seriously. The laying requirement also creates a public record of the exact text of every amendment.
For a person actually prosecuting a patent application, the working takeaway is that an amendment rule is effective from its commencement date and should be followed from that date. It does not sit in limbo waiting for parliamentary approval.
Why this section matters
Applicants and practitioners indirectly; Members of Parliament, industry bodies and policy groups directly.
It becomes relevant each time a set of amendment rules is notified and then tabled in Parliament.
It creates a duty on the government to table every rule and a power in Parliament to modify or annul it, with effect only for the future.
Without this safeguard, procedural rules could be reshaped with no legislative scrutiny and no public record of the change.
How it works in practice
A trade body follows an amendment through Parliament
The Coimbatore Precision Engineering Association objects to an amendment rule that changes how a particular statement must be filed. Its secretary, Meera Subramanian, writes to two Members of Parliament with a short note explaining why small workshops in the cluster find the new requirement difficult. The amendment is laid before both Houses in the usual way. Members raise the point in a discussion on delegated legislation, but no modification is agreed and the rule stands. Meanwhile the association advises members to comply from the commencement date, because a rule that is under scrutiny is still a rule. A year later the government revises the requirement on its own after further consultation. The episode shows both sides of Section 160. Parliament's power to modify or annul is real but rarely exercised, and the practical route to change is usually persuasion during consultation rather than intervention after the rule is tabled.
Simplified illustration only. Actual legal outcomes depend on the facts.
Key points to remember
- Every rule made under the Patents Act must be laid before both Houses of Parliament.
- The laying period is a total of thirty days while the Houses are in session, which may span successive sessions.
- Both Houses may agree to modify a rule or to annul it.
- Any modification or annulment works only for the future; acts already done under the rule remain valid.
- A notified rule is binding from its commencement date and does not wait for parliamentary approval.
Common mistakes and misunderstandings
- Thinking a new amendment rule is not yet enforceable because Parliament has not looked at it. The rule binds from the commencement date stated in the notification.
- Assuming annulment undoes past filings. If a rule is annulled, steps validly taken under it before annulment are not disturbed.
- Confusing this laying requirement with the separate consultation stage, where a draft is published for public comments before the rule is even made.
Connected provisions
Indian patent law works in two layers. The Act carries the substance and the Rules carry the machinery. Because the layers are amended by different processes and at different times, they are presented in separate blocks instead of being merged into one description.
Forms, deadlines and fees
- Rules must be laid before each House of Parliament for a total of thirty days while it is in session, which may be spread across successive sessions.

Where a fee is payable under this provision, the figure comes from the First Schedule. Categories of applicant are charged at different rates, and electronic filing is treated differently from paper filing, so an accurate number can only come from the Schedule in force on the day you file.

Related judgments
Case summaries are published only after a qualified reviewer has checked the judgment, the citation and the way the holding is described. Nothing has cleared that review for this provision yet, so nothing is listed here. We would rather show no case note than one that misstates what a court decided. How case notes are prepared.
Questions people ask about Section 160
Has Parliament ever annulled a patent rule in India?
Annulment of patent rules is not a feature of Indian practice. Delegated legislation across most Indian statutes is tabled routinely and very rarely modified or annulled on the floor of the House. The real influence of Section 160 is that it forces every amendment into the parliamentary record and encourages careful drafting. Where stakeholders want a rule changed, the effective route in practice has been the consultation stage before notification, or a later amendment by the government itself after industry feedback.
Do I need to wait for the laying period before following a new rule?
No. A rule made under the Act comes into force on the commencement date given in the notification, and it must be complied with from then. The laying requirement is a later scrutiny step, not a condition for the rule to become effective. If you delay compliance while waiting for Parliament, you risk missing a deadline that is already live. Follow the notified rule, and watch for any subsequent modification, which would in any event operate only for the future.
What does it mean that changes take effect without prejudice to anything previously done?
It means past acts are protected. Suppose a rule required a particular statement and applicants filed it, and Parliament later agreed the rule should not have been made. Those filings, and any decisions taken on the basis of them, stay valid. The rule simply stops operating from the date of the parliamentary decision onward. This protects applicants who acted in good faith and keeps the register and pending proceedings stable.
