*949The opinion of the Court was delivered by

Fenner, J.

The evidence establishes that, prior to 1873, most of the illuminating oils produced from petroleum, then in the market, were of low fire-test, and consequently inflammable, and also generated vapors which, in certain combinations with atmospheric air, liable to take place, became explosive and frequently caused destruction to life and property. Other oils, then in use, not inflammable or explosive, were deficient in illuminating or other qualities requisite to fit them for domestic use in ordinary lamps.

There existed an urgent public demand for an illuminating oil of this character, combining, with perfect safety, the other necessary qualities for family use.

With the view of supplying this demand, plaintiff instituted negotiations with certain oil refiners in Cleveland, Ohio, for the purpose of securing the production of an illuminating oil, having certain desiderated qualities as to color, specific gravity, flashing point, and fire-test.

Plaintiff succeeded, in 1873, in procuring an oil, manufactured for it and under its orders, possessing the required qualities, which, after examination, secured the public approval and recommendation of the Board of Health of this State and of the insurance companies of New Orleans and of other cities. To this oil plaintiff gave the name “Insurance Oil,” and adopted that name as its “ trade-mark,” under which it sold this particular oil, to distinguish it, not only from other different oils, but also from all oils sold by others than itself. Application was made, under the act of Congress, to the IT. S. Patent Office for the registry of this trade-mark and, after due examination, the Commissioner made the registry and issued the certificate. Plaintiff had made, and used, a stencil-plate containing the words: “ Trade-mark Insurance Oil, Pat. Jan. 5, 1875,” cut in letters of peculiar form and character and accompanied with certain distinctive scroll-work, with which it branded the packages containing this oil and sold by it.

Owing to the character of the oil and aided by active and expensive canvassing and advertising, plaintiff succeeded in establishing an extensive trade in this and contiguous States, profitable to itself and advantageous to the public — -the evidence showing that no accident has ever occurred from the use of this “ insurance oil.”

The defendant, a rival dealer in oils in this city, after the reputation of plaintiff’s oil had been thus established, commenced putting up and selling oils dealt in by him, as “Insurance Oil,” and had made a stencil-plate, the facsimile of that used by plaintiff, with which he caused his own packages to be branded and put upon the market.

Plaintiff brought the present suit to restrain, by injunction, the infringement of its trade-mark and to recover damages.

*950The defenses, interposed by exceptions and answer, are manifold, and will be considered in order.

1st. It was excepted that the plaintiff corporation did not, in its petition, appear by its proper officer, as required by law. The petition was in the na,me of the corporation without the designation of any officer. The exception was cumulated with the merits, and, on trial, it was proved that the action had been brought by the President with the approval of the Board of Directors. This cures the defect.

2nd. The objection raised to the validity of plaintiff’s act of incorporation, was not properly presented by the pleadings, and was waived by the express admission found in the record, viz.: “ It is admitted that the company is legally incorporated, and its name is the Insurance Oil Tank Company.”

The further objection that plaintiff is violating the law by carrying on a mercantile business, is not presented by the pleadings, nor was it considered in the lower court. It does not properly arise in this case. The sole question involved is plaintiff’s right to protection in the exclusive use of its trade-mark. Á corporation is entitled to have its trademark as well as a private individual, and may sue for its infringement. Defendant cannot justify his wrongful act, by accusing the plaintiff of violating some general law of the State, not affecting plaintiff’s right to have a trade-mark, but on a different subject. We express no opinion as to the legality of plaintiff’s business, in support of which much might, however, be said. We simply overrule the objection, because (1st) not presented by the pleadings, (2d) not relevant to the issues in this case, (3d) as being a question which defendant is without interest to raise.

3d. Defendant urges that the use of the abbreviation “ Pat.,” meaning patented, in the trade-mark, is a fraud on the public and a violation of law, which deprives plaintiff of the right to redress.

It is undoubtedly true that the affixing of the word “ patent” to an unpatented article, “ for the purpose of deceiving the public,” is prohibited, under penalties, by the laws of the United States. U. S. R. S. §4901; and that a representation in a trade-mark that an unpatented article is protected by a patent “ prima facie amounts to a misrepresentation of an important fact, which would disentitle the owner of the mark to relief in a court of equity, as against a pirate/’ Browne on Trade-Marks, § 572; Coddington’s Dig. Tr. M. Cases, § 548; 39 Conn. 450.

But, to have such effect, the use of the word “ patented ” must be “with the purpose of deceiving the public,” and if such fraudulent intention does not exist, and the use of the word may be explained in any reasonable sense consistent with truth and honesty, the party will not be prejudiced. ' High on Injunctions, § 674; Ooddington’s Dig. § 570, 571.

The plaintiff avers that the use of the word “ patented” in its label *951or brand was intended to refer, not to the article, Insurance Oil, but to the word Trade-mark placed on the top of the label. Had the words “Begistered in Patent Office” been used, no question could have arisen; but the use of the word patented, as applied to a trade-mark so registered, is so common; that we are referred to an example where so learned a jurist as Judge Oooley uses the language: “In the United States, trademarks may be patented, etc.” Oooley on Torts, p. 361, note. Under such circumstances, we consider the explanation of plaintiff as sufficient to maintain its honesty of intention.

. 4th. Objection is made that the words “ Insurance Oil ” are not a legal trade-mark, because the word “ insurance ” merely denotes the description or quality of the article, without, in any manner, indicating origin or ownership.

The law on this subject is tersely expounded by Judge Oooley: “In general, a man may adopt for a trade-mark whatever he chooses; but when he asserts, and seeks to enforce, exclusive right therein, it becomes-necessary to ascertain whether it is just to others that this be permitted. If the name, device or designation is purely arbitrary or fanciful, and has been first brought into use by him, his right to the exclusive use of it is unquestionable. But the mere designation of a quality, as ‘ nourishing’ applied to an article of drink, cannot be appropriated as a trademark; neither can any general description, by words in common use, of a kind of article, or of its nature or qualities.” The defendant contends that the trade-mark is defective, (1st) because the word insurance as applied to an illuminating oil, merely denotes the quality of safety, and may, therefore, be used by a vendor of any safe oil; (2d) that it indicates that the oil has been approved by insurance companies, and so may be employed as applicable to any oil having such approval. The learned judge of the court a qua sustained the defendant on these points and rejected plaintiff’s demand.

We cannot agree with our brother of the District Court. While the word insurance may, by some process of association of ideas, suggest the notion of safety, it is not synonymous with safe, nor can it be said to describe any possible quality of oil. The word is a noun substantive» not grammatically applicable to the description of the qualities of things. The dictionary furnishes several examples of its use as part of compound words, such as insurance-broker, insurance-clerk, insurance-company, insurance-office, insurance-policy — -all of which have well-understood-meanings; but insurance-oil is, in itself, meaningless, co’nveying no rational idea, any more than would the words, insurance-house, or insurance-tree.

Equally untenable is the idea that these words signify that the oil has been recommended by insurance-companies. That the selection of *952this name was suggested by the fact that it had received such approval, is admitted; but thatothe words express such a fact cannot be maintained.

We are strengthened in our conclusion by the decision of the Commissioner of patents in admitting this trade-mark to registry. The authorities of the patent office,- from long experience, are' familiar with the law of trade-marks, and their decisions, though not conclusive, are -entitled to great consideration by courts in the determination of such questions.

5th. It is urged that the trade-mark is detective because not indicating the origin or ownership of the article.

- There are authorities holding that it is essential to the validity of a trade-mark that it should indicate the name or address of the manufacturer or seller of the articles, in such manner as to distinguish them as the goods .made or sold by the parties claiming the benefit thereof.

We consider, however, that the latest and best authorities establish that such particular designation is not essential; but that when a particular form of words or device, otherwise valid as a trade-mark, has been first employed by a particular maker or seller, and has been used by him upon his goods, so long and so exclusively as to have acquired, by association, an understood reference to such maker or seller as the originator or seller of articles so marked — this will be a sufficient compliance with the law, and will entitle the party to protection.

Browne, Trade-Marks, §§ 150, 151; Charter Oak Case, 44 Mo. 173; 57 Barb. 526; 35 Cohn. 402; 13 Wall. 322; 101 U. S. 620; 3 Keyes, 594.

The evidence brings the case of plaintiff within the principle of these authorities.

6th. The objection that the oil is not directly manufactured by plaintiff, but only manufactured by others under plaintiff’s orders and directions, is of no force. The authorities are clear that, in such case, the seller is as much entitled to protection in his trade-mark as if he were the manufacturer. The ground of relief is stated by the Supreme Court of the United States to be that “ complainant has a valuable interest in the good will of his trade or business, and having adopted- a particular label, sign, or trade-mark indicating to his customers that the article bearing it is made or sold by him or by his authority, he is entitled to protection against one who attempts to deprive him of his trade or customers, by using such label, signs, or trade-mark without his knowledge or consent.” ,

*9537th. Attack is made upon plaintiffs right to equitable protection upon the ground that it has debauched its own trade-mark by selling thereunder, as insurance oil, oils which were not such. The occasional instances of such sales established by the testimony, are not sufficient, under any authority to which we have been referred, to maintain such forfeiture.

It is true that, on a few occasions, when by detention of its shipments, plaintiff has run short of insurance oil, it has temporarily supplied the trade, with different oil under that name; but the instances are few and the amount so sold inconsiderable, and care has been taken that the substituted article should equal the genuine, in safety, if not in all other qualities. We think this conduct, though reprehensible, was not carried to such extent as to destroy the value of the trade-mark or to deprive plaintiff of his right to protection.

In conclusion, we consider that the interest of the public, which is an important motive for the protection of trade-marks, is peculiarly involved in a case of this character. If,fas the record establishes, the plaintiff has so conducted its business as to~inspire the public with confidence that the insurance oil manufactured for, and sold by it under its trade-mark, is not only useful and convenient, but also absolutely safe, for use for illuminating purposes, and, thereby, to secure'a large and valuable trade based on such confidence — we think both the plaintiff and the public are entitled to protection in their mutual relations of confidence on the one hand and patronage on the other.

It may be, as contended by defendant, that the oil sold by him under plaintiffs trade-mark is equal, in all respects, to the oil of plaintiff. But, if defendant may use this mark, other less conscientious dealers may employ it for inferior and dangerous oils; and the public would thereby be deprived of the security now enjoyed in the purchase of oil so marked, and the business of plaintiff would be destroyed.

Defendant has no right, in justice or law, to trade upon the reputation and business sagacity and enterprise of plaintiff, which are represented by and embodied in its trade-mark.

We find in the record no sufficient proof upon which to base any estimate of damages.

It is, therefore, ordered, adjudged and decreed that the judgment appealed from be avoided and reversed; and it is now adjudged and decreed that the original inj unction herein issued be reinstated and made perpetual, and that plaintiff’s demand in damages be dismissed as in case of nonsuit, defendant and appellee to pay costs in both courts.

Rehearing refused.
