   THORNBERRY, Circuit Judge:

This is an appeal by Marvin Glass & Associates from the district court’s holding that Glass’ patent, No. 3,086,297, has not been infringed by Sears, 318 F. Supp. 1089. Sears cross appeals from the court’s holding that the patent is valid. We affirm the finding of non-infringement. It is, therefore, unnecessary to reach the question of validity.

The patented device in issue (hereinafter referred to as the Kay patent) is a talking book, designed for pre-school children. It consists of a suitcase-like box that opens to reveal a book containing a series of simple messages. To the right of and below the pages of the book is a control lever. Underneath the book within the box lies what is essentially a record player. The pages of the book have arrows on their right hand edge which, when matched with an arrow on the lever, permit the user to manually select a verbal message that corresponds to the written intelligence presently appearing in the book. Besides being used to select a particular message, the lever activates the battery-run turntable. On the turntable is a standard disc record. The control lever is connected to a sound pick-up needle and when the lever is shifted the needle is moved laterally between the outside edge and the center of the record to pick up different messages.

The accused device, manufactured by the Mattel Company and marketed by Sears, is also a talking book for very young children and accomplishes the same result as the Kay patent, producing an audible reproduction of the message presently visible on the pages of the book. The district court found non-infringement on two separate independent grounds: First, that the mode of operation of the two books is substantially different; and, second, that the accused book omits certain elements of the Kay patent claims in issue.

The court found substantial difference between the Kay patent, which utilizes an arm containing a sound pickup needle that moves laterally to a particular spot on the record, and the ae-cused device, on which the needle is stationary and the record is rotated beneath it to select a specific message.

It is well settled that infringement exists only when the accused device and the teachings of the patent in suit are substantially identical in structure, mode of operation, and results accomplished.

Stewart-Warner Corp. v. Lone Star Gas Co., 5th Cir. 1952, 195 F.2d 645, 648. See Fraser v. City of San Antonio, 5th Cir. 1970, 430 F.2d 1218, 1221; United States Indus. v. Otis Engineering Corp., 5th Cir. 1958, 254 F.2d 198, 204. We agree with the district court that the mode of operation of the Kay patent differs substantially from that of the Mattel book. Moreover, infringement is a question of fact. United States Indus. v. Otis Engineering Corp., supra at 200. We may not, therefore, reverse the district court unless its fact finding is clearly erroneous. Fed.E.Civ.P. 52(a). Surely it is not clearly erroneous to say that a device employing a fixed needle beneath which a record is rotated to select a message operates substantially differently from one in which an operating arm is moved laterally to a particular point on the record.

In Stewart-Warner Corp. v. Lone Star Gas Co., 5th Cir. 1952, 195 F.2d 645, 649, this Court said:

In this connection, it is well established that in order to support a suit for infringement of a combination claim such as here, an accused device must embody all the elements of the claim, and omission of a single element avoids infringement.

At issue in the instant case are claims 1, 2, 3 and 9 of the Kay patent, which is clearly a combination patent. The district court found an element of each of these claims missing in the accused device, namely: (1) A single manual control member to shift the pick-up unit; (2) a single sound track with blank spaces; (3) a circuit breaker or stop means; and (4) an index along an outer peripheral edge. Again, the test is whether the court’s fact findings were clearly erroneous. Assessing these findings by reference to the drawings and specifications of the Kay patent rather than solely to the Kay patent claims, as we have concluded we must, we hold that the district court’s findings were not clearly erroneous.

The crux of this case is whether the Kay patent is to be protected against any device that comes within the broad literal sweep of its claims or whether infringement is to be found only if the claims when narrowed by reference to the drawings and specifications of the patent can be read upon the accused device. The district court followed the latter course, and we concur.

Appellant argues that the four Kay patent claims can be read literally upon the accused Sears-Mattel book. This conclusion does not, however, even if correct, end our inquiry. Although there is broad language in a brief opinion from another circuit to the effect that allegedly infringing devices should be tested solely by the claims of the patent, American Technical Machine Corp. v. Caparotta, 2nd Cir. 1964, 339 F.2d 557, 560, cert. denied 382 U.S. 842, 86 S.Ct. 65, 15 L.Ed.2d 83 (1965), the rule in this Circuit is that patent claims are only a starting point.

[T]he claim of a patent must be read in the light of the invention disclosed and cannot be given a construction broader than the teachings of the patent as shown by the drawings and specifications.

United States Indus. v. Otis Engineering Corp., 5th Cir. 1958, 254 F.2d 198, 201; Fraser v. City of San Antonio, 5th Cir. 1970, 430 F.2d 1218, 1220. Moreover, the rule in this Circuit that courts must look beyond the literal meaning of the patent claims is applied even more strictly to combination patents. An inventor is not allowed a broad range of equivalents on a device that employs features that are well known individually in the prior art.

We hold, therefore, that the Kay claims, when construed by reference to the drawings and specifications of the patent, reveal a device that differs substantially in mode of operation from the accused device and that includes elements absent from the accused device.

In Sinclair & Carroll Co., Inc. v. In-terchemical Corp., 325 U.S. 327, 330, 65 S.Ct. 1143, 1145, 89 L.Ed. 1644 (1945), the Court said that “the better practice” in patent infringement suits “will usually be” to inquire fully into the issue of validity even after a finding of non-infringement has been made. This Court took a similar tack in Beckman Instruments, Inc. v. Chemtronics, Inc., 5th Cir. 1970, 428 F.2d 555. Nevertheless, we followed a different course in Fraser v. City of San Antonio, 5th Cir. 1970, 430 F.2d 1218. There we found non-infringement and thus no necessity to reach the issue of validity. We relied on the rationale of Judge Learned Hand’s opinion in Harries v. Air King Products, Inc., 2nd Cir. 1950, 183 F.2d 158, in which the court said:

The passage [quoted above from Sinclair] was not * * * a peremptory direction, but rather * * * a cautionary admonition, to be followed when that is the more convenient course. * * * * -X- * -X- * *
We hold that it is open to a court to proceed as is most convenient, subject to the exception ■ that, though the defendant has not infringed, claims may be so evidently invalid that the court should so declare.

The Kay patent is not evidently invalid. Moreover, the rationale of Sinclair is not present here. Because of the district court’s holding, which we affirm, on noninfringement, narrowing the Kay patent claims in light of the drawings and specifications, Glass is not in a position to use the patent to exact tribute from competitors or to foreclose the talking book field from competition. By its very nature, the Kay patent cannot be infringed by a device not substantially identical to it. We hold, therefore, that on the facts of this case neither precedent nor policy necessitates reaching the issue of validity, which has no bearing on resolution of the controversy between the parties to this suit.

The judgment of the district court holding that Patent No. 3,086,297 was not infringed by appellee is affirmed. That part of the judgment below which held the patent is valid is remanded to the district court with directions that it vacate its judgment in that regard.

Affirmed in part and in part remanded with directions.
