Case: Ruston &amp; Hornsby Ltd Vs. The Zamindara Engineering Co

2. The appellant is a limited liability company incorporated under the English Companies Act with its registered office at Lincoln, England. It carries on business in the manufacture and sale of diesel internal combustion engines and their parts and accessories. Ruston Hornsby (India) Ltd., a company registered in India under the Companies Act, 1956 is a subsidiary of the appellant. The respondent is a firm carrying on business in the manufacture and sale of diesel internal combustion engines and their parts. The appellant was a registered proprietor of the registered trade mark Ruston being registration No. 5120 in Class 7 in respect of internal combustion engines. Ruston and Hornsby (India) Ltd., is the registered user of the said trade mark and manufactures in India and sells in India internal combustion engines under the trade mark "RUSTON". Sometime in June, 1955 the appellant came to learn that the respondent was manufacturing and selling diesel internal combustion engines under the trade mark "RUSTAM". On July 8, 1955 the appellant wrote through its attorneys a letter to the respondent and called upon it to desist from using the trade mark "RUSTAM" on its engines as it was an infringement of the registered trade mark "RUSTON". The dependent replied that "RUSTAM" was not an infringement of "RUSTON" as the words "RUSTAM INDIA" was used. On February 17, 1956 the appellant instituted a suit praying for a permanent injunction restraining the respondent and its agents from infringing the trade mark "RUSTOM". On January 3, 1958 the Additional District Judge, Meerut, dismissed the suit holding that there was no visual or phonetic similarity between "RUSTON" and "RUSTAM". The appellant took the matter in appeal in the Allahabad High Court. By its judgment dated November 23, 1965 the High Court held that the use of the word RUSTAM by the respondent constituted infringement of the appellants trade mark "RUSTON" and the respondent should be prohibited from using the trade mark "RUSTAM". But the High Court proceeded to hold that the use of the words "RUSTAM INDIA" was not an infringement because the plaintiffs engines were manufactured in England and the defendants engines were manufactured in India. The suffix "India" would be a sufficient warning that the engine sold was not a "RUSTON" engine manufactured in England and the respondent may be permitted to use the combination "RUSTAM INDIA".

Court's reasoning:
4. The distinction between an infringement action and a passing off action is important. Apart from the question as to the nature of trade mark the issue in an infringement action is quite different from the issue in a passing off action.In a passing off action the issue is asthe defendant selling goods so marked as to be designed or calculated to lead purchasers to believe that they are the plaintiffst in an infringement action the issue is asthe defendant using a mark which is the same as or which is a colourable imitation of the plaintiffs registered tradean action for infringement where the defendants trade mark is identical with the plaintiffs mark, the Court will not inquire whether the infringement is such as is likely to deceive or cause confusion. But where the alleged infringement consists of using not the exact mark on the Register, but something similar to it the test of infringement is the same as in an action for passing-off. In other words, the test as to likelihood of confusion or deception arising from similarity of marks is the same both in infringement and passing-off actions.8. In the present case the High Court has found that there is a deceptive resemblance between the word "RUSTON" and the word "RUSTAM" and therefore the use of the bare word "RUSTAM" constituted infringement of the plaintiffs trade mark "RUSTON". The respondent has not brought an appeal against the judgment of the High Court on this point and it is, therefore, not open to him to challenge that finding. If the respondents trade mark is deceptively similar to that of the appellant the fact that the word INDIA is added to the respondents trade mark is of no consequence and the appellant is entitled to succeed in its action for infringement of its tradevery often happens that although the defendant is not using the trade mark of the plaintiff,theof the defendants goods may be so much like the plaintiffs that a clear case of passing off would be proved. It is on the contrary conceivable that although the defendant may be using the plaintiffs mark theof the defendants goods may be so different from theof the plaintiffs goods and the prices also may be so different that there would be no probability of deception of the public. Nevertheless, in an action on the trade mark, that is to say, in an infringement action, an injunction would issue as soon as it is proved that the defendant is improperly using the plaintiffs mark.6. The action for infringement is a statutory right. It is dependent upon the validity of the registration and subject to other restrictions laid down in Sections 30, 34 and 35 of the Act. On the other hand the gist of a passing off action is that A is not entitled to represent his goods as the goods of B but it is not necessary for B to prove that A did this knowingly on with any intent to deceive. It is enough that theof Bs goods has become distinctive of them and that there is a probability of confusion between them and the goods of A. No case of actual deception nor any actual damage need be proved.At common law the action was not maintainable unless there had been fraud on As part.
