Cavenah, et ah, on July 22, 1958, especially Claim 4 thereof, are and each of them is valid and infringed by the defendant’s devices.

Judgment will be for the plaintiff as prayed for in the Complaint. Single damages to be ascertained upon reference to a Master when the interlocutory decree shall have become final, unless the parties shall agree upon a basic licensing fee. (35 U.S.C.A. § 284)

Comment

It is accepted law that when a patent combines elements which produce, in combination, a new, better or different result there is invention over the prior art. 1 Walker on Patents, Deller’s Ed., 213, 215-216; 2 Ibid, 788-789; Hailes v. Van Wormer, 1874, 20 Wall. 353, 368-369, 87 U.S. 353, 368-369, 22 L.Ed. 241; Brinkerhoff v. Aloe, 1892, 146 U.S. 515, 516, 13 S.Ct. 221, 36 L.Ed. 1068; Himes v. Chadwick, 9 Cir., 1952, 199 F.2d 100, 106; Great Lakes Equipment Company v. Fluid Systems, Inc., 6 Cir., 1954, 217 F.2d 613, 617; Cold Metal Process Co. v. Republic Steel Corp., 6 Cir., 1956, 233 F.2d 828, 829; Application of Wynne, 1958, 255 F.2d 956, 45 CCPA 1018.

The patented device is a valid combination which conforms to this principle. In essence, what was done is to combine the skimming operation with the filtering operation of swimming pools into one apparatus in which “the old elements perform a new function in their new environment.” Cold Metal Process Co. v. Republic Steel Corp., supra, 233 F.2d at page 839.

The' old elements contained in the two apparatuses which the patented device combined were the weir, the throat, the removal basket and the waffle-type filters. New elements were also introduced.

As to the Pace patent the new element is the tank which has the skimming element formed as a part of it and which is capable of receiving both the basket and the filter element, which has in its bottom the removable fitting for receiving the core of the filter, the fitting being connected with a pipeline that runs to the pump.

As to the Cavenah patent the new elements are a vacuum intake below the weir throat and a shutoff plate seat in the tank below the weir throat, a removable shutoff plate to seat on that seat so as to shut off the flow from the weir and enable the vacuum to pull through the tank, the filter and the pump.

The new device has better visual appearance ; it is lighter, easier to operate and can be operated and cleaned more economically and without waste of water. Indeed, it can be operated and cleaned by unskilled labor, whereas the other two require skilled labor.

The combined apparatus prevents the accumulation of foreign matter in the pipes, protects the pump, and requires less maintenance and service. So, on the whole, we have a combination which achieves easier, better, newer and more economical results than the devices, the elements of which it has successfully combined. This is invention.

That the accused device infringes the patents in suit cannot be doubted. The deviations in its construction are not sufficient to avoid infringement. I am also of the view that the patent is valid and that not one of the patented devices cited, as to either patent, is anticipatory of or achieves these results in this manner.

Without going into a detailed analysis I state that this is also true of the best references cited as to Pace, such as British Patent 557,393, Wall 1,687,027, MacKinley 1,850,393 or Kracklauer 2,-639,291, and those cited as to Cavenah, such as Pace 2,844,255, Wise 1,074,769, King 2,701,235 or British Patent 348,794.

Hence the ruling above made.

Appendix “A”

Findings of Fact and Conclusions of Law

Pursuant to Rule 52 of the Federal Rules of Civil Procedure, 28 U.S.C.A. and Rule 7 of the Rules of Practice of the District Court of the United States for the Southern District of California, the Court makes the following Findings of Fact and Conclusions of Law:

Findings of Fact

1.

Landon, Inc., plaintiff, is a corporation of California and has a principal place of business at Belmont, State of California.

2.

Marine Swimming Pool Equipment Co., defendant, is a California corporation, having a regular and established place of business at Van Nuys, California, within the Southern District of California, Central Division.

3.

In the prior practical art the most commonly employed skimming and filtering systems for swimming pools employed a separate skimming device at the side wall of the pool; and sand and gravel filter tank or tanks of considerable dimensions positioned adjacent the pool together with the pump and auxiliary equipment. Such systems were commonly referred to as the “sand and gravel filtering systems”.

4.

Long prior to the inventions of the patents in suit there was a recognized need or want in the swimming pool industry for an improved skimming and filtering device and system which would overcome the recognized disadvantages of the commonly used sand and gravel filtering systems with a separate skimming device, which disadvantages were that these prior systems were unsightly, expensive, expensive to install, required! a dry hole or sewer connection to receive-a large volume of waste water during-cleaning and they required considerable: servicing.

5.

The inventions described and claimed! in the patents in suit satisfied the long felt want or need in the swimming pool' industry referred to in the previous finding.

6.

The device of the patents in suit replaced prior art filtering systems for residence swimming pools to a very large extent.

7.

The device of the patents in suit requires from 700 to 1000 gallons less water to effect a cleansing than the prior art sand and gravel filters which were the most commonly used filter mediums for residence swimming pools.
