Plaintiff-Appellant, Golden Bridge Technology, Inc. (Golden Bridge) appeals the decision of the United States District Court for the Eastern District of Texas granting summary judgment that claims 13 and 23 of U.S. Patent No. 6,574,267 ('267 patent), which is assigned to Golden Bridge, are anticipated by PCT Publication No. WO9746041 to Hakkinen et al. (Hak-kinen) and a May 1995 version of a Code Division Multiple Access (CDMA) standard called “Mobile Station-Base Station Compatibility Standard for Dual-Mode Wideband Spread Spectrum Cellular System,” TIA/EIA/IS-95A (IS-95A). We affirm the judgment of the district court that claims 13 and 23 are anticipated by the Hakkinen reference. Because we affirm the district court judgment of invalidity on the basis of the Hakkinen reference, we do not address the invalidation based upon the IS-95A reference.
BACKGROUND
The mobile communication system described in the '267 patent employs a CDMA scheme, where multiple mobile phones communicate at the same time with the same base station over the same frequency range by using different numerical “spreading codes” in their transmissions. 1 If too many mobile phones are transmitting simultaneously at high power levels, the mobile phones can interfere with each other. Therefore, there is a need to have *1321 each mobile phone transmit only as loudly as necessary to be heard by the base station. The '267 patent claims a technique to achieve this result, the gradual ramping up of the power signal in a CDMA system.
After Golden Bridge filed suit against Lucent, the district court held a claim construction hearing, and the parties shortly thereafter reached agreement on the construction of certain claim terms at issue in this appeal. Lucent and Nokia filed a motion for summary judgment that the asserted claims of the '267 patent were anticipated by the IS-95A and Hákkinen references. The motion was referred to a Magistrate Judge, who, after conducting a hearing and reviewing extensive briefing, recommended a finding of invalidity of the asserted claims of the '267 patent as being anticipated under 35 U.S.C. § 102(b) by each the IS-95A reference and the Hákki-nen reference. Golden Bridge objected and filed another brief articulating the reasons that the Hákkinen reference did not anticipate. Based upon further review and analysis of the evidentiary record, the district court adopted the Magistrate’s Report and Recommendation. The district court then entered summary judgment of invalidity from which Golden Bridge now appeals.
DISCUSSION
This court reviews a ruling of summary judgment
de novo. Liebel-Flarsheim Co. v. Medrad, Inc.,
The only argument that Golden Bridge advances on appeal with regard to whether the Hákkinen reference anticipates — that the Hákkinen reference does not disclose “synchronization prior to the transmission of the preamble ... in the uplink direction” — is an issue of fact never presented to the district court.
See Para-Ordnance Mfg., Inc. v. SGS Imps. Int’l, Inc.,
Golden Bridge does not contend that this alleged distinction between the claims and the prior art was subsumed in either its claim construction arguments presented to the district court or its arguments to distinguish the Hákkinen reference presented to the district court. Instead, Golden Bridge unequivocally admits that its factual contention is an entirely new argument raised for the first time on appeal and never presented to the district court. See Reply Br. 18 (Golden Bridge “concedes that it has presented a new argument ____”); id. at 19 (Golden Bridge has “introduced a new distinction between the claimed invention and the prior art.”); Oral Arg. at 1:43 (“We do concede that is a new argument.”).
Claim construction was completely resolved with regard to the “synchronization prior to the transmission” limitation prior to the motion for summary judg *1322 ment. In its summary judgment motion, Lucent contended that the Hakkinen reference taught all the claim limitations of claims 13 and 23. It presented expert testimony demonstrating how each limitation, including the synchronization limitation, was present in the Hakkinen reference. Golden Bridge opposed the motion for summary judgment of anticipation by the Hakkinen reference solely on the issue that “the random access procedure disclosed and claimed in the '267 patent differs from the procedure described in the Hakkinen publication in the manner in which the mobile station determines whether to re-transmit the preamble.” It focused solely on what it termed “the preamble interruption limitation.” It never even mentioned the synchronization limitation, which is indisputably distinct from the preamble interruption limitation. 2
Golden Bridge admits that it never argued to the district court that the Hak-kinen reference failed to disclose the “synchronization prior to transmission” limitation. Further, Golden Bridge does not argue to this court that it was in any way prevented from raising this argument in opposition to the summary judgment motion. In fact, Golden Bridge had multiple opportunities to present its arguments regarding why the Hakkinen reference failed to anticipate its claims. It filed an opposition to the summary judgment motion in which it detailed its arguments regarding the Hakkinen reference, but never mentioned the synchronization limitation. It then filed an opposition to the Magistrate’s Recommendation of invalidity based upon the Hakkinen reference, in which it again detailed its arguments, but never mentioned the synchronization limitation. At any of these points, Golden Bridge could have, and should have, raised its contention that the Hakkinen reference fails to teach the synchronization limitation of claims 13 and 23. Golden Bridge chose to focus its argument at all times exclusively on the preamble interruption limitation. Rather than appealing that issue, Golden Bridge now raises a new and entirely different ground on appeal — that the Hakkinen reference does not teach “synchronization prior to transmission.” We cannot sanction the iterative process Golden Bridge would like to pursue. It would be unfair to allow Golden Bridge to bring some arguments distinguishing the Hakkinen reference during proceedings at the district court and then, only after those arguments have been completely rejected, 3 bring entirely different arguments on appeal for the first time.
“[I]t is the general rule ... that a federal appellate court does not consider an issue not passed upon below.”
Singleton v. Wulff,
In
Forshey,
this court articulated an exemplary set of limited circumstances in which hearing arguments for the first time on appeal is appropriate: (1) “[w]hen new legislation is passed while an appeal is pending, courts have an obligation to apply the new law if Congress intended retroactive application even though the issue was not decided or raised below,”
The only explanation offered by Golden Bridge for why this court should consider this new argument on appeal is that it has new appellate counsel. Substitution of new appellate counsel is not one of, or even in proportion to, the limited circumstances outlined in Forshey. New appellate counsel does not present an exceptional case or circumstance in which our declining review will result in injustice. To hold otherwise would open the door to every litigant who is unsuccessful at the district court to simply hire new counsel and then argue he should get to raise new issues on appeal.
In asking us to decide whether the Hakkinen reference discloses synchronization prior to transmission, not only does Golden Bridge ask us to decide a new issue raised for the first time on appeal, but also is asking an appellate court to make factual findings. We decline to determine what a prior art reference discloses, a fact finding, in the first instance on appeal. Appellate courts review district court judgments; we do not find facts.
Middleton v. Dep’t of Def.,
Finally, Golden Bridge argues that if we will not decide the issue raised for the first time on appeal, this court should remand the case to the district court to consider its new argument because Lucent also presents new arguments and new evidence on appeal. Golden Bridge contends
*1324
that
Toxgon Corp. v. BNFL, Inc.,
We decline to remand this case to the district court to decide an argument as to what a prior art reference discloses when that argument, without any justification, is raised for the first time on appeal. For the foregoing reasons, we affirm the judgment of the district court that claims 13 and 23 are invalid as anticipated by the Hákkinen reference. In light of this holding, we do not reach the issue of whether the IS-95A reference would have also resulted in invalidity.
AFFIRMED
Notes
. Spreading codes enable the mobile phones and the base station to distinguish a particular wireless communication from other concurrent communications. See '267 patent col.5 ll.4-7 and ll.28-30.
. The preamble interruption limitation focuses on transmission. The synchronization limitation focuses on what must happen prior to transmission.
. Although it is not relevant to our determination of waiver of the argument related to the synchronization limitation, we do note that Golden Bridge completely abandoned the preamble interruption limitation arguments (the arguments made below) on appeal and has therefore waived any appeal of that determination.
