Wham-O-Mfg. Co., the owner of Carrier patent [U.S. Letters Patent #2982547, issued May 2, 1961] brought this suit against Paradise Manufacturing Co. for patent infringement and unfair competition. Both parties are corporations organized under the laws of California and have their principal places of business in that state.
The district court, concluding that the patent was invalid and not infringed, dismissed the infringement claim on defendant’s motion for summary judgment; and at the same time the court acting sua sponte dismissed the claim for unfair competition. Plaintiff has appealed. Finding no reversible error, we affirm the judgment.
The patent relates to an amusement device in the form of a slide. The patent claims comprise a combination consisting of a smooth strip of flexible material, such as vinyl plastic, and a sprinkler or “irrigating means” to moisten the surface of the material. The two components are integrated by attachment of the water conduit, either along a side or at an end of the strip. The contrivance is useful for a sport (?) referred to as “body planing.” Thus, when the slide is laid out and the surface wetted a player can hurl his body in a horizontal plane upon it and slide like a flat stone skipping upon a pond.
The district court declared that the presumption of validity arising from the grant of the Carrier patent [35 U.S.C.A. § 282, Neff Inst. Corp. v. Cohu Electronics Inc.,
It has long been settled that the separate presence in the prior art of each of the elements of a combination will not prevent the finding of invention.

But

the question remains whether the concept of the joinder of the parts evidences invention. In Great Atlantic and Pacific Tea Corp. v. Supermarket Equipment Corp.,
*751
We need not pause in the case at bar to determine whether the material and the sprinkler operate in combination to produce the requisite new unitary result. Even if we were of the opinion'— which we are not — [See Grinnell Washing Machine Co. v. E. E. Johnson Company,
Slides, of course, are not novel and we have no hesitancy in recognizing that they were a common type of amusement device long before the date of Carrier’s patent (May 2, 1961). The fact is likewise well known that a film of water will lower the co-efficient of friction of a smooth surface — in short, that a slide can be made more slippery than it otherwise would be by adding lubricant through means of a sprinkler. We think, as did the trial court, that the combination was obvious. Particularly apt are the following extracts from Glagovsky v. Bowcraft Trimming Co.,
By its judgment the District Court also determined and decreed that defendant’s slide, marketed under the name “Surf N’Glide” did not infringe any claims of the Carrier patent. In view of our conclusion that the patent was invalid, we do not reach the issue of infringement. A valid patent is essential to such a claim. Bergman v. Aluminum Lock Shingle Corp.,
*752 The propriety of the district court’s dismissal of the claim of unfair competition presents a more difficult question. Plaintiff had alleged in its complaint that the subject matter was within the pendent jurisdiction of the district court by virtue of 28 U.S.C.A. § 1338(b). That section provides that a district court may entertain and adjudicate “a claim of unfair competition when joined with a substantial and related claim under the * * * patent * * laws.” The district court clearly was of the view that loss of jurisdiction over the dependent claim was a necessary corollary of its ruling of patent invalidity. It opined that “The second count being for unfair competition finds no jurisdictional support in 28 U.S.C.A. 1338 (b), inasmuch as judgment goes against the plaintiff on the first count [i. e. patent infringement] and hence there is no ‘substantial and related claim’ under the patent law to support jurisdiction of the unfair competition count.” 5 In this the court erred.
The Supreme Court in Hurn v. Ours-ler,
Thus, in O’Brien v. Westinghouse Electric Corp.,
And in the case before us, although we are satisfied the district court did have jurisdiction over the non-federal subject matter, we believe that on this record the court, in the exercise of a sound discretion, had no choice but to dismiss the complaint with respect to that claim. Unlike Hurn v. Oursler, commented upon by Judge Magruder, or Telechron, Inc. v. Parissi,
The district court dismissed the unfair competition claim, but since the merits were not reached, the dismissal should *754 have been of the complaint and not the claim. This will permit plaintiff, if it so desires, to litigate the competition claim in an appropriate state court. The judgment is modified to recite that plaintiff’s complaint, as to the Second Count, is dismissed without prejudice to litigate any such cause of action in an appropriate state forum.
As modified, the judgment is affirmed. Costs to appellee.

. Defendant readily acknowledges that the claim of patent infringement was “substantial” but suggests it was not “re: lated” to the competition claim, as is also required by § 1338(b); the suggestion is made that such deficiency afforded the basis for the trial court’s dismissal. The term “related” refers to probative facts; it means that part of the proof in support of one claim be common to the other. The amount of the proof required varies among the several circuits, this circuit being among those that has adopted a liberal construction in order to facilitate joinder. Pursche v. Atlas Scraper Engineering Co.,
. We accept this statement as setting out the test of substantiality: “Presumably § 1338(b) means nothing more than the claim under the patent law must satisfy the test of substantiality generally exacted when a jurisdictional challenge is asserted in a federal court. In such instances the question is whether the claim jurisdietionally assailed is ‘obviously without merit’ or its unsoundness ‘ “clearly results from previous decisions” ’ of the Supreme Court.
