Before FRIEDMAN, BISSELL and MAYER, Circuit Judges.

BISSELL, Circuit Judge.

DECISION

Texas Instruments Incorporated (TI) appeals from that portion of the final decision of the United States International Trade Commission (ITC) holding (1) claims 12-15 and 17 of United States Letters Patent No. 4,043,027 ('027) invalid and not infringed by Samsung Company's (Samsung) encapsulating process, and (2) United States Letters Patent No. 3,541,543 ('543) unenforceable due to inequitable conduct before the United States Patent and Trademark Office (PTO). We reverse-in-part, vacate-in-part, and remand.

OPINION

I. The '543 Patent

The portion of the ITC's determination regarding the unenforceability of the '543 patent has already been vacated for mootness in a published order. Texas Instruments Inc. v. United States Int'l Trade Comm'n, No. 87-1627 (Fed.Cir. July 6, 1988).

II. The '027 Patent

A. The Disposition Below.

The claimed invention is a process for encapsulating semiconductor transistors and other electrical components in plastic packaging. In 1986 TI filed a complaint with the ITC charging nineteen different parties with violating United States tariff laws by importing 256K and 64K dynamic random access memory devices (hereinafter chips). TI alleged that the chips were encapsulated outside the United States by manufacturing processes that infringed numerous TI patents, including the '027 process patent. The administrative law judge (ALJ) in the initial determination found no violation of sections 337 and 337a, 19 U.S.C. Secs. 1337, 1337a (1982 & Supp. IV 1986), with respect to the '027 patent. She did, however, determine that claims 12-15 and 17 of the '027 patent were invalid for (1) lack of utility due to inoperativeness under 35 U.S.C. Sec. 101 (1982); (2) lack of enablement under 35 U.S.C. Sec. 112; (3) obviousness under 35 U.S.C. Sec. 103 (1982 & Supp. IV 1986); and (4) double patenting. See In re Certain Dynamic Random Access Memories, Components Thereof and Products Containing Same, Inv. No. 337-TA-242, slip op. at 142, 150, 152 (Int'l Trade Comm'n May 21, 1987) (hereinafter DRAM ). The ALJ also found that the Samsung process did not infringe the claims at issue either literally or under the doctrine of equivalents. Upon review, the ITC vacated that portion of the initial determination holding the '027 patent invalid for double patenting. Because the ITC determined not to review the ALJ's remaining findings and conclusions with respect to the '027 patent, they became final on September 21, 1987. We address each issue seriatim.

B. Inoperativeness, 35 U.S.C. Sec. 101

TI contends that the ALJ made a critical error of law in interpreting claims 12-15 and 17 of the '027 patent to require that the molten plastic flow into the mold in a particular flow pattern as depicted by the swirling arrows in Figure 5 and described in the specification at column 5, lines 41-50. We agree. There is no dispute that when the '027 patent issued in 1977, the inventors incorrectly believed that their claimed invention worked in the way depicted in Figure 5. See DRAM, slip op. at 130-31. However, an inventor need not understand how or why his claimed invention works as long as the claimed invention can be practiced by one skilled in the art. Fromson v. Advance Offset Plate, Inc., 720 F.2d 1565, 1570, 219 USPQ 1137, 1140 (Fed.Cir.1983). Conversely, if the inventor claims a misconception, the patent must be held invalid. Raytheon Co. v. Roper Corp., 724 F.2d 951, 956, 220 USPQ 592, 596 (Fed.Cir.1983), cert. denied, 469 U.S. 835 (1984).

Here, the ALJ held that the claims at issue incorporated an "erroneous theory of how gate location affects plastic flow." DRAM, slip op. at 152. In other words, she concluded that the encapsulation process disclosed in the '027 patent did not work as described and required by the claims at issue. Based on this claim interpretation, the ALJ found that the claims at issue lacked utility under section 101 because they contained inoperative language. Id. at 136-37, 152.

The ALJ's finding is clearly erroneous because it is based on improper claim construction. Moleculon Research Corp. v. CBS, Inc., 793 F.2d 1261, 1268-69, 229 USPQ 805, 810 (Fed.Cir.1986), cert. denied, 107 S.Ct. 875 (1987) (stating that utility requirement under section 101 is reviewed as a question of fact). The claims at issue do not require that the flow pattern depicted in Figure 5 be present. For example, claim 12 calls for a particular relationship between the location of the gate and the semiconductor device whereby the fluid will not directly engage the device at high velocity. There is no expressed incorporation in the claim of the incorrect theory that the plastic must enter and flow from bottom to top as depicted in Figure 5 of the patent. See Smith v. Snow, 294 U.S. 1, 11 (1935) (refusing to limit the claim to that shown in the specification and drawings). The ALJ's analysis violates a basic rule of claim construction--that claims are to be construed so as to preserve their validity. See, e.g., ACS Hosp. Sys., Inc. v. Montefiore Hosp., 732 F.2d 1572, 1577, 221 USPQ 929, 932 (Fed.Cir.1984). Accordingly, the ITC's final determination on this issue is reversed.

C. Enablement, 35 U.S.C. Sec. 112.

Because the ALJ committed the same errors of claim construction delineated above, we reverse that portion of the ITC's final determination holding claims 12-15 and 17 of the '027 patent invalid under section 112 for nonenablement. See DRAM, slip op. at 137, 152.

D. Obviousness, 35 U.S.C. Sec. 103.

The ALJ also held claims 12-15 and 17 of the '027 patent invalid under section 103. See DRAM, slip op. at 142, 152. This court has stated that once the claims of a patent have been improperly construed, that improper construction permeates, and typically disables, the entire remaining legal analysis.
