E-Pass Technologies, Inc. (“E-Pass”) appeals from a final summary judgment of non-infringement by the United States District Court for the Northern District of California, in which the court held that none of the defendants directly or indirectly infringed E-Pass’s U.S.' Patent No. 5,276,311 (“the '311 patent”). E-Pass Techs., Inc. v. 3Com Corp., Nos. 00-CV-2255, 03-CV-4747, 04-CV-0528 (N.D.Cal. Mar. 17, 2006) (“SJ Order ”). Because the district court correctly determined that no reasonable jury could have found any of the defendants liable on the basis of the evidence presented, summary judgment was propеr, and we affirm.
*1216 I. BACKGROUND
A. Introduction and Prior Appeal
As we discussed in a prior appeal in this case,
E-Pass is the assignee of the '311 patent, entitled “Method and Device for Simplifying the Use of a Plurality of Credit Cards, or the Like.” The object of the invention is to provide a method and device for substituting a single electronic multifunction card for multiple credit cards.... To address problems associated with carrying multiple cards, “the user needs, and is required to carry about, [only] a single card.”
E-Pass Techs, v. 3Com Corp.,
A method for enabling a user of an electronic multi-function card to select data from a plurality of data sources such as credit cards, check cards, customer cards, identity cards, documents, keys, access information and master keys comprising the steps of:
transferring a data set from each of the plurality of data sources to the multifunction card;
storing said transferred data set from each of the plurality of data sources in the multi-function card;
assigning a secret code to activate the multi-function card;
entering said secret code into the multifunction card to activate the same;
selecting with said activated multi-function card a select one of said data sets; and
displaying on the multi-function card in at least one predetermined display area the data of said selected datа set.
'311 patent, col. 10, l. 54-col. 11, l. 3.
On February 28, 2000, E-Pass filed a complaint for patent infringement against 3Com Corporation and Palm, Inc. (collectively, “3Com”). In it, E-Pass accused 3Com of inducing consumers to practice the steps of the patented method on its Palm VII and Palm VIIx personal digital assistant (“PDA”) products. Following a claim construction that construed “electronic multi-function card” to be “[a] device having the width and outer dimensions of a standard credit card with an embеdded electronic circuit allowing for the conversion of the card to the form and function of at least two different single-purpose cards,”
E-Pass Techs, v. 3Com Inc.,
E-Pass appealed. On appeal, we held that the district court had erred by “requiring the dimensions of a standard credit card.”
E-Pass I,
B. Events After Remand
After we remanded the action against 3Com, E-Pass filed two new infringement *1217 actions in the district court. It filed the first new аction, Case No. 03-CV-4747, on October 22, 2003, against Visa U.S.A., Inc., and Visa International Service Association (collectively, “Visa”). In that action, E-Pass alleged that Visa had infringed the '311 patent by using a Palm V PDA in two demonstrations in 2001. E-Pass filed the second new action, Case No. 04-CV-0528, against PalmSource, Inc., palmOne, Inc., and Handspring, Inc., on February 9, 2004. In the second new action, it made claims of direct, induced, and contributory infringement of the '311 patent based on three new PDA product lines — the Tungsten, Zire, and Treo lines — that had been introduced since the filing of the initial action.
On March 17, 2006, the district court granted summary judgment of nonin-fringement as to all defendants. SJ Order. It rested its finding of noninfringement on two independent grounds. First, it held that even under a broader construction of “card,” none of the accused devices could infringe the “electronic multi-function card” limitation. Id., slip op. at 25-34. Second, it held that E-Pass had failed to adduce sufficient еvidence to support a finding that any of the defendants or their customers had practiced all of the steps of the claimed method. Id., slip op. at 17-25. Having demonstrated no instances of direct infringement, E-Pass could not prove liability for induced or contributory infringement.
E-Pass appeals. We have jurisdiction pursuant to 28 U.S.C. § 1295(a)(1).
II. DISCUSSION
We review without deference all of the issues here on appeal: the propriety of the district court’s grant of summary judgment,
see E-Pass I,
On appeal, E-Pass challenges both grounds upon which the district court rested its judgment of noninfringement. First, it argues that the district court violated this court’s mandate in E-Pass I when it grаnted summary judgment of noninfringement based on the “electronic multi-function card” limitation. It further argues that even without consideration of the law of the case, summary judgment as to that limitation was improper either as a matter of literal infringement or under the doctrine of equivalents. Second, it argues that the district court ignored circumstantial evidence that the defendants or their customers practiced the steps of the claimed method. Thеrefore, it argues, summary judgment as to the step limitations was improper.
To prevail, E-Pass must convince us to overturn the district court’s rulings as to both issues. We consider each of its arguments in turn.
A. The “Electronic Multi-Function Card” Limitation
1. Law of the Case
“Once a case has been decided on appeal, the rule adopted is to be applied, right or wrong, absent exceptional circumstances, in the disposition of the lawsuit.”
Gindes v. United States,
a. Summary Judgment
E-Pass’s first argument rests in substantial part on our statement in
E-Pass I
thаt “issues of material fact remain in dispute as to both literal and doctrine of equivalents infringement under the proper construction” of the term “card.”
E-Pass I,
The balance of our opinion in
E-Pass I
supports this interpretatiоn. We discussed in detail the claim construction of the term “card” and the district court’s error in construing “card” to mean a card with the precise dimensions of a standard credit card.
E-Pass I,
Accordingly, the district court correctly concluded that it had the authority to entertain the defendants’ motions for summary judgment on remand.
SJ Order,
slip op. at 11, 12;
see also Liquid Dynamics Corp. v. Vaughan Co., Inc.,
b. Claim Construction
In
E-Pass I,
we addressed the question of whether the district court had improperly added a dimensional limitation to the claim. See
Following our decision in
E-Pass I
and prior to the district court’s ruling on remand, our court, sitting en banc, decided
Phillips.
Nonetheless, any articulated definition of a claim term ultimately must relate to the infringement questions that it is intended to answer.
See Wilson Sporting Goods Co. v. Hillerich & Bradsby Co.,
Even so, the district court’s observation was correct. For example, no reasonable jury, if properly instructed, would conclude that a 4' x 8' x piece of plywood or a plate glass window infringes the “card” limitation of '311 patent clаim 1. See id. The specification of the '311 patent makes it clear that a “card,” as used in the patent’s claims, is something a user will “carry about.” See, e.g., '311 patent, col. 1, 1. 44. Although not a precise restriction on size or portability, the attributes of being able to be “carried about” and of not having protruding buttons, keyboards, antennae, indented display screens, or hinged covers are characteristics that a complete claim construction of “card” can be expected to embrace.
*1220
Moreover, we reiterated in
Phillips
the paramount importance to claim construction of the language of the claims themselves.
See Phillips,
2. Literal Infringement
Answering this question of infringement brings us, as it brought the district court, back to an application of the claim construction in E-Pass I. As the district court correctly observed, the accused devices are neither flat nor rectangular:
They have buttons, joysticks and keyboards which project above the surface. They have screens which sit below the surface. Some have indented spaces holding a stylus which can be used on the device. They have projecting antennae. The Treo cell phone has a full QWERTY keyboard and a flip cover which sits at a 150 degree angle to the surface of the phone when it is open.
... A review of the accused devices ... shows that none of them meet the definition [of rectangular]. Corners and edges are fully rounded. The sides of the devices are generally curved, some convex, some concave, rather than straight. They have built-in or flip-up antennae which completely alter the straight line sides of a rectangle. Some have USB connectors which have the samе effect.
SJ Order,
slip op. at 31-32. Likewise, the accused devices are not “piecefs] of stiff material,”
see E-Pass I,
E-Pass argues that in performing its infringement analysis, the district court improperly treated the words of our claim construction as additional claim limitations. E-Pass is correct that “[c]laim interpretation is the process of giving proper meaning to the claim language,”
Abtox, Ine. v. Exitron Corp.,
Accordingly, we affirm the district court’s grant of summary judgment of non-infringement as to the “electronic multifunction card” limitation.
3. The Doctrine of Equivalents
The above discussion does not resolve the question of whether the accused devices might meet the “card” limitation of claim 1 under the doctrine of equivalents. The district court held that “[flnasmuch as the patent method must be performed on a *1221 card, a performance on something that is not a card cannot be considered to be a performance in the same way as that required by the patent, and cannot constitute infringement by the doctrine of equivalents.” Id., slip op. at 36. However, this conclusion is too summary.
Under the “all elements” rule, “the doctrine of equivalents must be applied to individual elements of the claim, not to the invention as a whole.”
Warner-Jenkinson Co. v. Hilton Davis Chem. Co.,
E-Pass’s theory of equivalence is that no reasonable jury could conclude that the differencеs between the accused products and the “electronic multi-function card” of the '311 patent are substantial. Mot. for Summ. J. of Infringement Against PalmOne, Inc., E-Pass, Inc. v. 3Com, Inc., Nos. 00-CV-2255, 03-CV-4747, 04-CV-0528 (N.D.Cal. Aug. 26, 2005) (Dckt. No. 464). This is the proper inquiry. To hold that performance of the claimed method on something not a card is not “a performance in the same way as that required by the patent,” SJ Order, slip op. at 36, is to beg the question of whether the accused devices — which, taken as a whole, arе alleged to meet a single limitation of the claimed method — are unsubstantially different from a “card.”
We need not decide whether the district court’s judgment as to the doctrine of equivalents can be sustained on other grounds, nor indeed whether the alleged equivalence of the accused devices to cards is amenable to summary judgment. As we discuss next, we agree with the district court that E-Pass has failed to meet its burden of proof on the questiоn of whether anyone has practiced the steps of the claimed method. This, without more, warrants affirmance.
B. The Steps of the Claimed Method
The district court held, simply, that “E-Pass has submitted
no
evidence that the patented method has ever been practiced on any Palm VII device. The same circumstance is true as to the Tungsten, Zire and Treo devices — there is no evidence that the patented method has ever been practiced on any of these devices.”
SJ Order,
slip op. at 17. E-Pass argues that this summary conclusion improperly ignores circumstantial evidence of direct infringement that supports its claim of inducement of infringement as to all of these devices. We disagree; we have no reason to believe that the district court ignored any of this evidence, all of which was before it.
Cf. Medtronic, Inc. v. Daig Corp.,
*1222
E-Pass’s difficulty is twofold. Procedurally, it is hornbook law that to survive the defendants’ motions for summary judgment, E-Pass must “make a showing sufficient to establish the existence of [each] element essential to [its] case.”
Celotex Corp. v. Catrett,
The documents that E-Pass cites on appeal are not sufficient to meet its burden under Celótex. First, it cites a chart of documents produced by Visa, showing that Visa was interested in PDA-based payment technology. However, this chart does not demonstrate that Visa actually performed or induced anyone to perform all of the steps of the claimed method, much less that it did so in the necessary order and in the United States. Second, it cites to a Visa document describing plans for a contactless payment demonstration in Cartes, France, in 2004. This, too, fails to demonstrate that the steps of the method were actually performed, much less that they were performed in the United States. Likewise, its citations tо business analyses of proposed contactless payment protocols fail to show that any such protocol was ever actually deployed or that, if deployed, it would infringe.
E-Pass’s final piece of evidence, to which it devotes the bulk of its argument, is a set of excerpts from the product manuals for various of the accused devices. These, it argues, establish infringement under
Moleculon Research Corp. v. CBS, Inc.,
In contrast, the evidence here shows, at best, that the Palm defendants taught their customers each step of the claimed method in isolation. Nowhere do the manual excerpts teach all of the steps of the claimed method together, much less in the required order. Accordingly, it requires too speculative a leap to conсlude that any customer actually performed the claimed method. Indeed, the very same record evidence upon which E-Pass attempts to rely also shows that the accused PDAs are general-purpose computing devices that can be used for a variety of purposes and in a variety of ways. In comparison, the device at issue in Moleculon was intended to be used in only one way — to practice the infringing method — and that method was еxplicitly taught by the proffered instructions. Id. If, as E-Pass argues, it is “un *1223 fathomable” that no user in possession of one of the accused devices and its manual has practiced the accused method, see E-Pass Repl. Br. at 16, E-Pass should have had no difficulty in meeting its burden of proof and in introducing testimony of even one such user. Having failed to meet that burden, E-Pass has no basis to overturn the district court’s decision.
III. CONCLUSION
For the foregoing reasons, we conclude that the district court prоperly granted summary judgment in favor of the defendants. Accordingly, the judgment is
AFFIRMED.
Notes
. Of course, the decision in
E-Pass I
does not constitute law of the case as to parties and accused devices that were not yet part of the litigation when that decision issued.
See Jamesbury Corp. v. Litton Indus. Prods., Inc.,
. E-Pass does not raise in its opening brief any arguments against the district court's finding that there is no evidence of infringement during the two demonstrations that E-Pass described in its complaint against Visa. See SJ Order, slip op. at 17-25. Accordingly, and because we see no reason why doing so would be unfair, we exercise our discretion and deem this issue to have been waived. See Becton Dickinson & Co. v. C.R. Bard, Inc., 922 *1222 F.2d 792, 800 (Fed.Cir. 1990) ("[A]n issue not raised by an appellant in its opening brief ... is waived.”); id. (noting that the rule "may as a matter of discretion not be adhered to where circumstances dictate that it would result in basically unfair procedure”).
