Opinion

DECISION AND ORDER

McMILLEN, District Judge.

The issues in the case have been reduced to Count I for infringement of certain claims of Frenzel Reissue Patent 26,781 and Count II for a declaration of invalidity of Matthews patent 3,389,3651 The plaintiff Skil Corporation as owner of the Frenzel reissue patent contends that the defendant Lucerne Products, Inc. infringes Frenzel by manufacturing and selling a switch control device under Sahrbacker patent # 3,603,757 which defendant owns. 35 U.S.C. § 271(a). The defendant contends its devices do not infringe Frenzel and also that Frenzel is invalid because of non-obviousness and anticipation. For reasons to be discussed, we find that the presumption of validity of the Frenzel reissue patent remains intact on its claim 5 only.

Count II is a declaratory judgment action to declare invalid defendant’s Matthews et al patent 3,389,365 on the grounds, inter alia, of a commercial sale and a publication more than one year before the filing date of August 23, 1965. A ease or controversy exists because plaintiff is manufacturing devices which defendant contends infringe the Matthews patent. We find and conclude that the Matthews patent is invalid because it was dedicated to the public under 35 U.S.C. § 102(b).

Plaintiff alleges that the defendant is infringing the original claims 2, 3 & 5 contained in the Frenzel reissue patent. This invention consists of three primary elements which in combination distinguish it from the prior art. The first element is an adjustable assembly connected to the trigger which allows the range of the trigger’s movement to be controlled. This correspondingly con *1259 trols the speed of the motor. The second element consists of a locking device whereby the trigger can be detained in any adjusted position. The third element is referred to in the claims as “catch means” carried by a lug, enabling the operator to finely adjust the motor’s speed after the trigger is locked in an operating position. The patentee refers to this aspect of his invention as the “vernier” effect (see Frenzel patent, col. 4, lines 60-73).

The defendant attacks the Frenzel patent as merely a combination of old elements and therefore not entitled to patentability, citing A & P Tea Co. v. Supermarket Corp., 340 U.S. 147, 71 S.Ct. 127, 95 L.Ed. 162 (1950) and Toro Mfg. Corp. v. Jacobsen Mfg. Co., 357 F.2d 901 (7th Cir. 1966). These cases do not hold, however, that a combination of old elements cannot result in an invention, but merely that a combination of old elements must be carefully scrutinized to determine their novelty. The issued patent retains its presumption of validity during this scrutiny.

The old elements in the case at bar are illustrated by Sparklin patent No. 2,525,839 and an Ingersoll-Rand pneumatic impact tool. The Sparklin patent, considered by the Patent Office in its original examination of the Frenzel invention, is similar in two significant ways to Frenzel: the trigger is used to control the speed of the mechanism and can be locked in position. This is what Claims 1 and 2 of Frenzel’s patent consist of. Sparklin fails, however, to teach two of the three primary elements of Frenzel: the adjustable assembly and vernier “catch means”. Sparklin’s invention is incapable of achieving this result, but it does preclude Claims 1 and 2 of Frenzel’s patent on the ground of obviousness, if not complete anticipation.

The Ingersoll-Rand pneumatic, variable speed tool is significant in that it teaches a screw adjusting means as part of the trigger control, precluding Claim 3 of Frenzel as obvious. However, Frenzel’s adjustable assembly is comprised of more than a simple screw to control the trigger’s stroke. In order to carry out his vernier feature, it is essential that the catch means move relative to the trigger. This is accomplished by element 24 of the Frenzel device which carries the catch means and allows it to move relative to the trigger. The Ingersoll-Rand tool does not embody this feature, or the capability for finely adjusting the motor’s speed once an operating position has been achieved.

Thus the prior art taught a locking means for a trigger and a means for varying the range of the trigger’s stroke. It fails to suggest Frenzel’s vernier adjustment and fails to teach the means necessary to implement such an idea. In particular, it is the unique combination of elements 24, 27 and 42 in connection with the trigger which results in the fine adjustment or vernier capability that we find totally lacking in Sparklin and the Ingersoll-Rand tool or any other prior art brought to our attention.

From the Sparklin invention of 1950 to Frenzel, the defendant has failed to show a single piece of prior art that has remotely suggested the vernier feature. We are satisfied, in light of this record, that Claim 5 of the Frenzel device, when taken as a whole, would not have been obvious to a person having ordinary skill in the related art at the time the invention was made. 35 U.S.C. § 103.

The plaintiff has also satisfied this court that the Frenzel patent has met with considerable commercial success. Although commercial success is not in itself a basis for establishing a patent’s validity, it is a further indication of the patented feature’s nonobviousness. Graham v. John Deere Co., 383 U.S. 1, 17, 18, 86 S.Ct. 684, 15 L.Ed.2d 545 (1950).

Defendant also contends that certain employees of the Singer Co. developed a device anticipatory of Frenzel’s in the Spring of 1965. This became Winchester et al patent No. *1260 3,439,248 filed January 4, 1966, shortly after Frenzel’s original filing. Singer has recently filed interference # 97,893 in the Patent Office claiming prior invention. 35 U.S.C. § 102(g). This court has declined to await the outcome of the interference proceeding, and defendant has filed depositions of certain Singer personnel herein. We find that these depositions do not establish priority of the Singer device by the weight of the evidence. They show that Singer’s formal testing occurred in December 1965, considerably after the filing date of Frenzel’s original application, and that the model allegedly constructed and operated by Singer personnel in the Spring of 1965 was never used to drill any holes, was never reduced to detailed production drawings or recorded in formal testing documents, and was inoperable at the time of the depositions in May 1971. Without purporting to rule on the merits of Singer’s pending interference, since it is not a party herein, we find and conclude that defendant in the case at bar has not established that the Winchester invention was reduced to practice prior to Frenzel’s device and therefore cannot be anticipatory.
