Opinion

WOODBURY, Chief Judge.

This is another chapter in protracted litigation in this and other circuits involving a group of patents for electrical systems and apparatus for use primarily in the art of radio communication issued to the late George Washington Pierce. 1 This time we have before us four appeals by the plaintiff below. One pair of appeals is from a single final judgment entered in two cases consolidated in the District Court for the purpose of hearing and trial which, with costs to the defendants, (1) granted their motions for summary judgment and denied like motions in each case by the plaintiff with respect to four patents, Nos. 2,133,642, 2,133,645, 2,133,646 and 2,133,648, and (2) dismissed the plaintiff’s complaints and granted the defendants’ counterclaims for declarations of invalidity as to all claims of the above patents and also two others, Nos. 2,133,643 and 2,266,070. The other pair of appeals is from the denial of a motion by the plaintiff under Rule 59(e) F.R.Civ.P., 28 U.S.C.A., to alter or amend the above judgment and from the denial of her motion to correct docket entries. All four appeals were consolidated and docketed as a single case in this Court.

This chapter in the litigation over the Pierce patents opened in 1951 with a complaint by the patentee against American Communications Company, Inc., American or American Communications hereinafter, charging it with infringing the six patents already mentioned and still another one, No. 2,133,-644. 2 In that suit both parties moved under Rule 56 F.R.Civ.P. for partial summary judgment as to thirteen claims (claims 51, 52, 54, 55, 56 and 61 to 68 inclusive), of the basic patent of the group, No. 2,133,642. Holding the above claims valid and infringed, the District Court granted the plaintiff’s motion and denied the defendant’s. On appeal, however, this court reversed. American Communications Co., Inc. v. Pierce, 1 Cir., 1953, 208 F.2d 763. In our view the thirteen claims involved were invalid, wherefore we remanded for entry of a judgment for the defendant.

In April, 1954, soon after our decision in the American case, the patentee filed a complaint in the court below charging Mackay Radio and Telegraph Company, Inc., Mackay hereinafter, with infringing the six patents enumerated above. The two cases proceeded on their separate ways in the District Court until September, 1958, when that court granted the defendants’ motions for a joint trial. Prior to that time, however, in January, 1958, the court below had granted motions by both defendants for summary judgment insofar as four of the six patents in suit were concerned but had denied the motions with respect to the other two which we shall refer to hereinafter as the ’643 and ’070 patents. After an extended trial without a jury the court below concluded that all claims of the two latter patents were invalid. Wherefore it entered the final judgment with respect to all six patents, and soon thereafter the orders denying the plaintiff’s motions from which the plaintiff below has taken these appeals.

We first turn our attention to the four patents as to which the District Court granted the defendants’ motions for summary judgment.

The District Court held that all of the claims of all of these patents were invalid for double patenting for the reason that in substance and essence they claimed the same invention disclosed and covered in the claims of a prior patent, No. 1,789,496, issued to Pierce on Janu *280 ary 20, 1931, which, of course, expired seventeen years later on January 20, 1948. This earlier patent issued on an application filed on January 18,1928, as a division by Patent Office order of an application filed on February 25, 1924, which in the Commissioner’s belief described more than one invention. It covered in its three claims radio transmitting and receiving systems each with a two electrode electromechanical vibrator, preferably in the form of a piezo-electric crystal in a single vacuum tube circuit the utility of which was to obtain constant frequency of the oscillations of each system to a far greater extent than had previously been possible. To gain some idea of what we understand this to mean it will first be necessary to describe briefly and in general what is known in the art as the heterodyne receiving system which was not new with Pierce.

A radio antenna picks up radio waves sent out by the sending or transmitting station. That is to say, it operates as a conductor in a magnetic field (radio waves are electromagnetic), and as it intersects or cuts through the field an electric current is induced in the antenna of the same frequency as that sent out by the transmitting station. The electric current induced in the antenna first passes through the radio frequency amplifier in the receiving set where its power is increased but its frequency is not changed. From the amplifier the current next goes to the first detector, known as the mixer or converter, where the heterodyning action takes place.

This action can best be described by illustration. Let us suppose that the electric current picked up by the antenna and entering the first detector from the frequency amplifier has cyclical variations of 50,000,000 per second, i. e., 50 megacycles. For reasons we need not explain this frequency is far too high; in some way it must be reduced. This is the function of the local oscillator in the receiving set which furnishes a frequency slightly different from that of the sending station to produce a “beat.” This “beat” produced by the difference between the frequency of the oscillations of the receiver and the frequency of the oscillations of the transmitter, as we pointed out in another chapter in the litigation over the Pierce patents, 3 is comparable to the beat produced when two tuning forks of slightly different frequency are caused to vibrate at the same time. Now let us assume that the local oscillator in the receiving set furnishes a frequency of 50,001,000 cycles, although it would make no difference if it furnished a frequency sightly lower than that of the sending station. The important thing is variation between frequencies of the sending and receiving stations. In our illustration this variation is 1,000 cycles, a frequency better adapted for ultimate conversion to sound in the receiving set.

The radio process from this point on to the production of audible sounds is not too important for present purposes, and we need not attempt to describe it.

Dr. Pierce was not the inventor of this heterodyning action, nor was he the first person to use a piezo-electric crystal in an oscillator. Prior to Pierce a Dr. Cady had patented an oscillator in which the crystal controlled oscillations produced elsewhere in the circuit but did not itself produce oscillations. Pierce’s contribution to the art was to show an oscillator wherein the crystal not only controlled the frequency, as in Cady, but itself actually produced the frequency or oscillations. In Cady the circuit could oscillate independently of the crystal since the crystal did not produce but merely controlled oscillations produced elsewhere in the circuit.
