LEGAL ANALYTICAL RESEARCH PAPER
Chemco Plastic Industries Pvt. Ltd. vs. Chemco Plast

---

Brief Introductory Headnote Summary

This case concerns a dispute over the trademark “CHEMCO.” The Plaintiff, Chemco Plastic Industries Pvt. Ltd., sought an interim injunction against the Defendant, Chemco Plast, alleging trademark infringement and passing off. The central issue was whether the Defendant’s use of the name “CHEMCO PLAST” and related domain name infringed upon the Plaintiff’s registered trademark and whether the Plaintiff, claiming earlier user and ownership, was entitled to exclusive protection under Indian trademark law.

This order explores the proof of ownership, prior usage, and trademark rights under Section 29 of the Trade Marks Act, 1999, and analyses whether the Defendant’s continued use should be restrained pending trial. The Court partly granted injunction relief on infringement while declining passing-off protection.

Factual Background

The Plaintiff is engaged in manufacturing plastic products like PET bottles, containers, closures, and home utility items under the trademark “CHEMCO”, claiming user since 1973. The Plaintiff asserts that the mark is distinctive and widely recognized in the industry.

The Defendant, a partnership firm operating under the name “CHEMCO PLAST”, claims user since 1977 through predecessors-in-title. The Defendant states it has used the name openly and continuously in business operations, including invoices, product marketing, and its domain name www.chemcoplast.com registered in March 2006.

Both parties manufacture similar products and operate in overlapping markets.

Procedural Detail

The Plaintiff filed:

• A Commercial Intellectual Property Suit (No. 80/2024)
• An Interim Application (No. 2165/2024) seeking temporary injunction.

The Plaintiff prayed for a restraining order stopping the Defendant from:

• Using the mark “CHEMCO” or “CHEMCO PLAST”
• Operating the domain name
• Passing off its goods as those of the Plaintiff
• Appointing a Court Receiver to seize infringing products.

The Defendant contested the allegations, denying infringement and asserting prior continuous user and bona fide adoption.

Arguments were heard, reserved on 20th June 2025, and order pronounced on 3rd December 2025.

Core Legal Dispute

The main points of conflict were:

• Whether the Defendant’s use of “CHEMCO” or “CHEMCO PLAST” infringes the Plaintiff’s registered trademark under Section 29 of the Trade Marks Act, 1999.
• Whether the Plaintiff could claim earlier ownership or uninterrupted use through its predecessors.
• Whether passing off action was maintainable based on goodwill, misrepresentation, and damage.

The dispute centered on prior user rights, assignment history, registration validity, and likelihood of confusion.

Detailed Reasoning and Judicial Analysis

The Court performed extensive analysis on trademark history, validity of assignment, parallel user claims, and applicability of infringement under Section 29.

The Plaintiff asserted longstanding use and registration across multiple Classes including 11, 16, 20, 21 and 22, which provided statutory rights to enforcement under Section 28 and 29.

While assessing flow of title, the Court observed challenges in Plaintiff’s version. The Plaintiff initially carried business under different names, including “Net-Guard Polynet Pvt. Ltd.” before adopting the name Chemco Plastic Corporation. The Court found that there was no clear assignment document transferring goodwill or the mark “CHEMCO” from earlier entities to the Plaintiff. This weakened the claim of continuity of ownership.

The Defendant produced evidence showing:

• Use of the term "CHEMCO" since 1977
• Invoices
• Membership in plastic manufacturing associations
• Domain registration predating Plaintiff's

The Court noted that the Defendant had never secured trademark registration and attempted filing on a “proposed to be used” basis, which was subsequently abandoned.

In applying Section 29, the Court held:

• Use of identical or similar marks on similar products may constitute infringement even without proven damage.
• Use of identical marks for domain names and trade identities must be examined carefully where public confusion is possible.

The Court distinguished between infringement and passing off. It found evidence of Defendant attempting to use the mark "CHEMCO" as a trademark beyond business name usage. Documents such as reply to cease-and-desist notice and website screenshots confirmed Defendant asserting trademark identity.

The Court relied on precedents including:

• S. Sayed Mohideen vs. P. Sulochana Bai (Supreme Court)
  (Explained distinction between passing off and infringement)
• Power Control Appliances vs. Sumeet Machines Pvt. Ltd.
  (Principle of one mark, one source, one proprietor)
• T.G. Balaji Chettiar vs. Hindustan Lever Ltd.
  (Requirement of clear proof of prior user and assignment)

The Court concluded that while both parties raised serious factual controversies requiring trial, the Plaintiff established a prima facie case of infringement under Section 29.

However, since both parties coexisted in the market for decades and the Defendant had developed goodwill under its business identity, a blanket injunction was held inequitable.

---

Decision

The Court partly allowed the Interim Application.

The order restrained the Defendant from using:

• CHEMCO or CHEMCO PLAST as a trademark for products
• Any identical or deceptively similar trademark to Plaintiff’s registered mark

The Defendant, however, was not restrained from continuing business using the trade name “CHEMCO PLAST” or domain name, pending trial, given long market presence and unresolved factual disputes.

Passing off relief was rejected due to weak evidence of deception and delayed enforcement.

Execution of the order was stayed for six weeks.

---

Concluding Note

This case highlights the complexity of trademark disputes involving shared historical use, family-controlled businesses, and absence of clear assignment or ownership transfer documentation. Indian courts continue to balance trademark exclusivity against long-standing bona fide use by others.

The decision underscores that registration confers statutory strength, but long delay and coexistence may restrict interim relief. The final determination of rights now remains subject to evidence at trial.

LEGAL NEWS SUMMARY

The High Court of Bombay, in its order dated 3rd December 2025, passed by Hon’ble Justice N. J. Jamadar in Interim Application No. 2165 of 2024 in Commercial IP Suit No. 80 of 2024, titled Chemco Plastic Industries Pvt. Ltd. vs. Chemco Plast, delivered an important ruling concerning trademark infringement relating to the use of the mark "CHEMCO."

In this case, the Plaintiff, Chemco Plastic Industries Pvt. Ltd., alleged that the Defendant, Chemco Plast, was infringing its registered trademark “CHEMCO” and sought an interim injunction restraining the Defendant from using the trademark, trade name, packaging, and website address associated with the disputed mark. The Plaintiff claimed long-standing prior use since 1973 and argued that the Defendant's continued use of "Chemco Plast" would mislead consumers and dilute the value of its trademark.

The Defendant opposed the injunction and asserted that it had been using the name since 1977 through its predecessor entities and had built substantial goodwill in the market. The Defendant also argued that both parties had coexisted in the industry for decades, and therefore the injunction would cause irreparable loss to its ongoing business.

After hearing the arguments and reviewing the evidence, the Court concluded that the Plaintiff had established a prima facie case of trademark infringement under Section 29 of the Trade Marks Act, 1999, considering the Plaintiff’s registered rights. However, the Court also acknowledged the Defendant’s long-standing presence in the market. As a result, the Court issued a partial injunction, restraining the Defendant from using “CHEMCO” or “CHEMCO PLAST” as a trademark for its goods, but did not prevent the Defendant from continuing business under the trade name or using its domain name pending trial. The relief sought for passing off was declined due to insufficient evidence demonstrating deception or confusion at this interim stage.

The execution of the order has been stayed for six weeks to allow compliance.

This order highlights the Court’s balanced approach between protecting registered trademark rights and acknowledging long-standing market coexistence, particularly in matters involving competing claims of goodwill and historical usage.
