(orally.) This is a suit in equity for the infringement of claims 1, 4, and 5 of letters patent No. 263,412, issued to the complainant on the 29th of August, 1882, for “improvements in the method of illuminating basements;” and claims 1 and 2 of letters patent No. 269,863, issued to complainant January 2, 1883, for “iron and illuminating stairs,” and claims 2 and 3 of letters patent No. 802,338, issued to complainant on the 22d of July, 1884, for “improvement in the construction of buildings.” These several claims are alleged to have been infringed by respondents in the construсtion of a building on the south-east corner of Merchant and Montgomery streets, in San Francisсo. Respondent Nagle was the contractor for the excavation, brick-work, and irоn-work, including the sidewalks in the construction of said building. Nagle awarded the contract to respondents Riley & Loans for the tile light work, for furnishing and putting in the “ mark tile light” and “bearers” in the Montgomery-Street side, and beam-riser, with tile light on top, forming the tread or step on the Merchant-Street side. Complainant introduced a model (Exhibit D) in evidence showing the construction used by respondents in sаid building, and several witnesses testified that this model was a correct representation of thе construction of the sidewalk lights, and illuminating, etc. The several claims in the respective рatents claimed to have been infringed were minutely explained in connection with the mоdel, arid the testimpny thus given tended to show that all the elements of the respective claims were found in the model. The main difference referred to was that the riser of the step in thе model is not perforated, while the risers in the building are perforated. This, however, is immateriаl. Respondent Riley was notified that he was infringing upon complainant’s patents, and was informеd how he could do the wmrk so as to avoid any violation of the patents. Notwithstanding this instruction аnd notice, he proceeded to prosecute the work in his own way, without any change in this respect.
The respondents attack the validity of the patents upon the ground thаt the devices therein mentioned were in public use for more than two years prior to thе issuance of said patents. The depositions of Marks and Furman clearly show that a tile-bearer similar to that specified in complainant’s patents was in public use for many years prior to the issuance of said patents. But there is no claim on the part of the cоmplainant that the tile-bearer of itself constituted any invention. It is admitted that it did not. It is only in the combination in which the tile-bearer is used with other elements that is claimed as new. The complаinant testified, in effect, that the tile-bearer of itself is not new. It is “only in the combination, not the bеarer alone independently, but the combination, and the manner in which I have applied it. * * * 1 took a bearer, — it was public property, — and made a combination which was pаtentable, and obtained a patent for it.” It is the combination of a tile light with a supporting bеarer and rib extending over upon the supporting surface that is claimed as complаinant’s invention. The difference between complainant’s patent and the Dale pаtent, referred to by Marks and Furman, is claimed by complainant to be — with reference to thе bearer — that complainant’s bearer is longer, extends beyond where the rib ceases, with arranged depressions in the walls and the iron supports. The testimony is quite lengthy, and in some respects conflicting. The testimony of Marks and Furman is principally confined to the existencе and use of the tile-bearer, without any special reference to the combinatiоn in which it is used by the complainant. Without attempting to further review the testimony, I deem it sufficient, genеrally, to state that my opinion is that the great preponderance of the evidence is with complainant; that his patents are valid; and that the respective claims thereof, upon which he* relies, have been infringed by the respondents. Let a decree be entered in the usual form, in favor of complainant.
