Infringement of Layout-Design under the Semiconductor Act, 2000

Updated 11 October 2026 · Fact-checked

A registered layout-design is infringed when someone who is not the proprietor or a registered user reproduces it, or imports, sells or distributes it for commercial purposes, without entitlement (Section 18). Solve questions by checking registration, the act done, the defences, then the remedy. Unregistered layout-designs cannot be sued on (Section 16).

Understand Infringement, Remedies and Offences

A layout-design is the three-dimensional arrangement of circuit elements in a semiconductor integrated circuit. The Semiconductor Integrated Circuits Layout-Design Act, 2000 protects it through registration. The Act extends to the whole of India.

The starting point is Section 17. If registration is valid, the registered proprietor gets the exclusive right to use the layout-design and to obtain relief for infringement. Under the Explanation, this right exists whether or not the layout-design is incorporated in an article.

Section 16 is the gatekeeper. No one can start any proceeding to prevent, or to recover damages for, infringement of an unregistered layout-design. In your answer, limit yourself to what Section 16 says. Registration comes first.

Section 18 defines infringement in two limbs. Clause (a) is reproduction of the registered layout-design, in whole or in part, whether by incorporating it in a circuit or otherwise. Parts that are not original under Section 7(2) are excluded. Clause (b) is importing, selling or otherwise distributing for commercial purposes the layout-design, a circuit incorporating it, or an article incorporating such a circuit, where the person is not entitled to use it under the Act.

The rest of Section 18 is a list of exceptions. Learn them well, because case questions are usually decided by them. Also note that a registered user can complain before the competent criminal court in his own name as if he were the proprietor (Section 28), subject to any agreement between the parties. Appeals from the Appellate Board go to the High Court (Section 53).

Key rules to remember

Who can infringe: Infringer = a person who is NOT the registered proprietor or a registered user; Section 18(1). The proprietor and registered users fall outside this definition, subject to Section 18(4), where the proprietor's use of a registered reverse-analysis design is treated as infringement.
Limb (a): reproduction: Reproducing the registered layout-design in whole or any part, except a part that is not original under Section 7(2); Reproduction may be by incorporating in a circuit or otherwise.
Limb (b): commercial dealing: Importing / selling / otherwise distributing for commercial purposes the layout-design, the circuit, or an article incorporating it, without entitlement; Subject to the innocent infringer rule in Section 18(5).
Research exception: Reproduction for scientific evaluation, analysis, research or teaching = not infringement; Section 18(2). It applies only to clause (a) reproduction and only for these limited purposes.
Reverse analysis: Original layout-design created on the basis of scientific evaluation or analysis = may be freely used; Section 18(3). If the original proprietor uses that new design after its registration, it is infringement (Section 18(4)).
Innocent infringer: No knowledge and no reasonable ground to know = no infringement; after notice, may continue for stock on hand or ordered before notice, but must pay royalty; Section 18(5). Royalty is fixed by negotiation or by the Appellate Board, having regard to the benefit accrued.
Downstream buyer: Purchaser from an innocent person referred to in Section 18(5) gets the same immunity; Section 18(6). It follows the protection given under Section 18(5), so it covers the protected units only.
Consent and exhaustion: Written consent of the proprietor, or goods put on the market by or with the proprietor's consent = not infringement under clause (b); Section 18(7).
Independent creation: Identical layout-design created by independent intellect = not infringement; Section 18(8).
Unregistered design: No proceeding to prevent or recover damages for infringement of an unregistered layout-design; Section 16.
Appeal: Appellate Board order to High Court within the prescribed period; Section 53. The Code of Civil Procedure, 1908 applies to such appeals.
False connection with Registry: Imprisonment up to six months, or fine, or both; Section 58. It applies to wording that suggests a place of business is connected with the Registry.

How to solve Infringement, Remedies and Offences questions

Use the same sequence for any fact-based question on infringement. Apply the provision to the facts and then conclude.

1Check registration first. If the layout-design is unregistered, Section 16 bars any proceeding for infringement, and you can stop there.
2Identify the parties. Under Section 18(1), infringement is by a person who is not the proprietor or a registered user. Remember the exception in Section 18(4) for the proprietor's use of a registered reverse-analysis design. Check for a joint proprietor (Section 14).
3Classify the act. Is it reproduction (clause (a)) or import, sale or distribution for commercial purposes (clause (b))?
4Test originality for partial copying. A copied part that is not original under Section 7(2) is not covered by clause (a).
5Run the exceptions in order: research or teaching (18(2)), reverse analysis (18(3)), innocent infringer (18(5)) and buyer (18(6)), consent or market exhaustion (18(7)), independent creation (18(8)).
6State the remedy. Mention the relief for infringement under Section 17, the proprietor's right to royalty where Section 18(5) applies, and the registered user's right to complain under Section 28.
7Mention the appeal route to the High Court under Section 53 if the question involves an Appellate Board order.
8Conclude clearly: infringed or not, and what the proprietor can do.

Quickest way: Five-question screen

When to use it: Use it when you have about ten minutes for a case-based question and need a quick, complete structure.

Registered? If no, Section 16 ends the claim.
Who did it? A stranger, or the proprietor or a registered user?
What did they do? Reproduce, or import, sell or distribute commercially?
Any exception? Research, reverse analysis, innocence, consent, independent creation.
Conclusion plus remedy and appeal: write one line each.

Common mistakes in Infringement, Remedies and Offences

Advising an unregistered owner to sue for infringement under this Act.
Students carry over ideas from other IP laws and forget that registration is the base of the right here.
Fix: Quote Section 16: no proceeding to prevent, or to recover damages for, infringement of an unregistered layout-design can be instituted. Stay within what Section 16 says.
Treating every copying of any part as infringement.
Students overlook the carve-out in clause (a).
Fix: Remember that reproduction of a part which is not original under Section 7(2) is excluded.
Treating research reproduction as covering commercial sale.
Students read Section 18(2) too widely.
Fix: Section 18(2) protects only the act of reproduction for scientific evaluation, analysis, research or teaching. Selling goods is a separate clause (b) question.
Saying an innocent buyer has no liability at all, even after notice.
Students stop reading Section 18(5) after the first half.
Fix: After notice, the person may continue only for stock on hand or ordered before notice, and must pay royalty fixed by negotiation or by the Appellate Board.
Missing that independent creation is a complete defence even for an identical design.
Students assume identical means copied.
Fix: Quote Section 18(8): an identical layout-design created by independent intellect is not infringement.
Inventing penalty figures for infringement.
Students try to recall the offence provisions from memory.
Fix: State only what you are sure of. Section 58 is certain: up to six months, or fine, or both, for falsely suggesting a connection with the Registry.

Worked examples

Example 1

Vidyut Chips Pvt Ltd, Bengaluru, holds a registered layout-design. A university lab in Pune copies it fully to study its structure and teach students. Later, a trader, Sahil Electronics, imports and sells circuits made with the same design, knowing it is registered, without any consent. Advise on infringement.

Show the solution

Registration: the layout-design is registered, so Section 17 gives the proprietor the exclusive right and the right to relief.
University lab: it reproduces the design (clause (a)) but only for scientific evaluation, analysis and teaching. Section 18(2) says this is not infringement.
Sahil Electronics: it is not the proprietor or a registered user, and it imports and sells for commercial purposes (clause (b)).
Exceptions: Sahil knows of the registration, so Section 18(5) does not help. There is no written consent and no market release by or with the proprietor's consent (Section 18(7)). There is no independent creation (Section 18(8)).
Conclusion: Sahil Electronics infringes; the university does not.

Answer: The university lab's copying is protected under Section 18(2). Sahil Electronics infringes under Section 18(1)(b), and Vidyut Chips can seek relief for infringement under Section 17.

Example 2

Meera Traders bought a consignment of circuits in good faith, having no reason to know they incorporated a registered layout-design. Last month the proprietor served notice. Meera has 500 units in stock and had ordered 300 more before notice. She wants to continue selling and also plans to order 1,000 new units. Advise.

Show the solution

Before notice: Meera had no knowledge and no reasonable ground to know, so under Section 18(5) her acts before notice are not infringement.
After notice: she may continue acts only in respect of the stock on hand or ordered before notice. That is 500 + 300 = 800 units.
Royalty: for those 800 units she must pay the proprietor royalty, fixed by negotiation or by the Appellate Board, having regard to the benefit she has derived.
New order: the 1,000 new units are ordered after notice, so they fall outside the protection of Section 18(5). If there is no written consent and no market release by or with the proprietor's consent (Section 18(7)), and no other exception applies, dealing in them is infringement under Section 18(1)(b).
Her own customers: a buyer from Meera gets immunity under Section 18(6) only for the protected 800 units. Section 18(6) does not extend to the 1,000 new units.

Answer: Meera may sell the 800 units on hand or already ordered, paying royalty, and her buyers of those units are immune under Section 18(6). Ordering and selling the 1,000 new units falls outside Section 18(5) and would infringe under Section 18(1)(b), absent consent or another exception.

Exam tips

Start every case answer with registration. Mention Section 16 even if the facts look straightforward.
Learn Section 18 sub-section by sub-section. Cite the sub-section numbers next to each exception, because examiners reward precise reference.
Use the provision, analysis, conclusion format. Do not stop after quoting the section.
If the facts involve an unregistered layout-design, quote Section 16 and conclude that no proceeding for infringement can be instituted. Do not add remedies that the provisions do not give.
Cite only numbers you are sure of. Section 58 (six months, fine or both) is safe; do not invent other penalty figures.

Infringement, Remedies and Offences: frequently asked questions

What amounts to infringement of a layout-design?

Under Section 18(1), a person who is not the registered proprietor or registered user infringes by reproducing the registered layout-design in whole or part, or by importing, selling or distributing it for commercial purposes without entitlement. Unoriginal parts are excluded from the reproduction limb.

Can I sue for copying of an unregistered layout-design?

No. Section 16 says no one may institute any proceeding to prevent, or to recover damages for, infringement of an unregistered layout-design. Registration is therefore essential.

What is the difference between infringement of a registered and an unregistered layout-design?

Infringement under Section 18 concerns a registered layout-design, and Section 17 gives the proprietor the right to relief. For an unregistered layout-design, Section 16 bars any proceeding to prevent, or to recover damages for, infringement.

Who can appeal and where?

A person aggrieved by a decision or order of the Appellate Board can appeal to the High Court within whose jurisdiction the relevant Registry office is situated, within the prescribed period. The appeal is by written petition, and the Code of Civil Procedure, 1908 applies (Section 53).

Can a registered user take action against infringers?

Yes. Subject to any agreement between the parties, a registered user may make a complaint before the competent criminal court for infringement in his own name as if he were the registered proprietor (Section 28).
