CARDSOFT (аssignment for the Benefit of Creditors), LLC, Plaintiff-Appellee v. VERIFONE, INC., Hypercom Corp., Verifone Systems Inc., Defendants-Appellants Ingenico S.A., Ingenico Corp., Ingenico Inc., Way Systems, Inc., Defendants.

No. 2014-1135.

United States Court of Appeals, Federal Circuit.

807 F.3d 1346

court found—and the parties do not contest—that but for the government‘s easement, the railway easements would have lapsed and the land would have returned to the landowners. Because the railway companies did not hаve an obligation to remove the physical railroad construction features, and there is no evidence in the record that they would have done so, the landowners would have regained possession of their land with the physical structures. See (interpreting Iowa law pertaining to the abandonment of railway rights, and emphasizing that a railroad has a right to enter and remove the physical track materiаls). Absent the NITUs, the land would have returned to the landowners with the physical remnants of the railway. A proper appraisal methodology has to account for those physical conditions.

Further, “[i]n ascertaining market value, consideration should be given to all matters that might be brought forward and reasonably be given substantial bargaining weight by persons of ordinary prudence....” Appraisal Institute, Uniform Appraisal Standards fоr Federal Land Acquisition § B-2 (2000 ed.); see also (defining fair market value). Here, all experts agreed that a reasonably prudent buyer would consider evidence of an abandoned railway when formulating an offer for agricultural property. Thus, a “before” calculation that does not take into account the costs of removing the physical remnants of the railway will result in an artificially inflated value and yield a windfall to the landowner.1 See (The property owner “must be made whole but is not entitled to more.“); see also (just compensation “should be carefully tailored to the circumstances of each particular case” (citing )).

III

Having concluded that the trial court applied the incorrect methodology in calculating the compensation owed to the landowners, we must vacate and remand for new proceedings under the proper standard with both sides having the opportunity to address the valuation for the effects of the remnants.

Before PROST, Chief Judge, TARANTO and HUGHES, Circuit Judges.

HUGHES, Circuit Judge.

The case returns to us on remand from the Supreme Court. In , we decided an appeal by defendant-appellants (collectively, VeriFone) from a decision of the United States District Court for the Eastern District of Texas. In construing the patent claims, the district court adopted plaintiff-appellees’ (collectively, CardSoft‘s) proposed construction for the claim term “virtual machine.” Applying the district court‘s construction, a jury returned a verdict for CardSoft. Because the district court erred in its construction of “virtual machine,” and because CardSoft waived any argument that Appellants infringe under the correct construction, we reversed the district court‘s decision.

Following our first decision in this case, the Supreme Court held that we must review a district court‘s ultimate interpretation of a claim term, as well as its interpretations of “evidence intrinsic to the patent,” de novo and its subsidiary factual findings about extrinsic evidence for clear error. See . The Court also vacated and remanded our CardSoft decision for further consideration in ‍‌‌‌‌​​​​​​‌​‌‌​‌‌​​​​​​​​‌​​‌​​‌​​​‌​‌​​​​​​‌‌‌​‍light of this new standard of review. . Because this case does not involve the factual findings to which we owe deference under Teva, we again reverse the district court‘s construction of the term “virtual machine.”

I

CardSoft filed suit in March 2008 against VeriFone, asserting infringement of U.S. Patent Nos. 6,934,945 (the ‘945 patent) and 7,302,683 (the ‘683 patent). The district court held a Markman hearing in July 2011 and conducted a jury trial in June 2012. The jury determined that certain VeriFone devices infringed claim 11 of the ‘945 patent and claim 1 of the ‘683 patent and that these claims were not invalid. VeriFone moved for a new trial and for judgment as a mattеr of law, but the district court denied both motions. VeriFone appeals. We have jurisdiction under 28 U.S.C. § 1295(a)(1).

II

The ‘683 patent is a continuation of the ‘945 patent and shares the same specification. Both patents describe software for controlling a payment terminal. See ‘945 patent col. 1 ll. 10–17. Payment terminals are small, specialized computers, and include a processor, peripheral units like a card reader, a display, a printer, or a communications interface, and a software operating system to control the hardware components. Id. at col. 2 l. 64-col. 3 l. 1.

According to the patents, prior art payment terminals used a variety of “different hardware/software architectures.” Id. at col. 2 ll. 34-37. But this variety of different architectures meant that each application program for a payment terminal neеded to be written specifically for that terminal. Id. at col. 3 ll. 5-11. “[P]rogramming alterations are not ‘portable’ between different types of devices.” Id. at col. 3 ll. 13-14.

To solve this problem, the specification describes a “virtual machine,” acting as an “interpreter” between an application program (like a particular merchant‘s payment processing software) and a payment terminal‘s underlying hardware and oрerating system. Id. at col. 3 ll. 29-36. Instead of writing a payment processing application for a particular hardware configuration or operating system, a developer can write the application for the virtual machine. Id. at col. 3 ll. 41-45. This application can then run on any payment terminal running the virtual machine, creating “a complete portable environment for program operations.” Id. at col. 3 ll. 45-46.

The specification acknowledges that the concept of a virtual machine was well known at the time, but argues that the slowdown in operation created by a conventional virtual machine would create a “performance penalty” that could be a “significant problem” for a payment terminal. Id. at col. 3 ll. 35, 47-49. To solve this problem, the specification describes an improved virtual mаchine optimized for use on specialized portable computers, like payment terminals. This improved virtual machine includes a specialized “virtual message processor” designed to optimize network communications. Id. at col. 3 ll. 56-67. It also includes a specialized “virtual function processor” designed to optimize control of the payment terminal itself. Id.

Claim 1 of the ‘945 patent is representаtive ‍‌‌‌‌​​​​​​‌​‌‌​‌‌​​​​​​​​‌​​‌​​‌​​​‌​‌​​​​​​‌‌‌​‍of the asserted claims:

A communication device which is arranged to process messages for communications, comprising a virtual machine means which includes

a virtual function processor and function processor instructions for controlling operation of the device, and

message in[str]uction means including a set of descriptions of message data;

a virtual message processor, which is arranged to be called by the function processor and which is arranged to carry out the message handling tasks of assembling the messages, disassembling messages and comparing the messages under the direction of the message instruction means that is arranged to provide directions for operation of the virtual message processor, whereby when a message is required to be handled by the communications device the message processor is called to carry out the message handling task,

wherein the virtual machine means is emulatable in different computers having incompatible hardwares or operating systems.

Id. at col. 50 ll. 48-67 (emphases added).

III

VeriFone appeals the district court‘s construction of “virtual machine,” found in all asserted claims. It argues that the district court erred by not requiring the claimed “virtual machine” to include the limitation that the applications it runs are not dependent on any specific underlying operating system or hardware. We agree. Because the district court‘s construction does not reflect the ordinary and customary meaning of “virtual machine” as understood by a person of ordinary skill in the art, we reverse.

A

We review the district court‘s ultimate interpretation of patent claims de novo. . “[W]hen the district court reviews only evidence intrinsic to the patent (the patent claims and specifications, along with the patent‘s prosecution history), the judge‘s determination will amount solely to a determination of law, and [we] will review that construction de novo.” Id. at 841. If, on the other hand, a district court resolves factual disputes over evidence extrinsic to the patent, we “review for clear error those factual findings that underlie a district court‘s claim construction.” Id. at 842. But as we have repeatedly held after Teva, it is not enough that the district court may have heard extrinsic evidence during a claim construction proceeding—rather, the district court must have actually made a factual finding in order to trigger Teva‘s deferential review. See, e.g., (citing ); (“Teva cannot transform legal analysis about the meaning or significance of the intrinsic evidence into a factual question simply by having an expert testify on it.“); see also (“[S]ubsidiary fact-finding is unlikely to loom large in the universe of litigated claim construction.“). And even then, we may nevertheless review the district court‘s constructions de novo if the intrinsic record fully determines the proper scope of the disputed claim terms. See, e.g., (citing ); (reviewing claim construction de novo, and declining to consider “findings on [extrinsic] evidence because the intrinsic record [was] clear“); (“To the extent the district court considered extrinsic evidence in its claim construction order or summary judgment order, that evidence is ultimately immaterial to the outcome because the intrinsic record is clear.“). In this case, we review the district court‘s construction de novo, as the district court did not make any factual findings based on extrinsic evidence that underlie its constructions of the disputed claim term.

Claim terms are generally given their ordinary and customary meaning ‍‌‌‌‌​​​​​​‌​‌‌​‌‌​​​​​​​​‌​​‌​​‌​​​‌​‌​​​​​​‌‌‌​‍as understood by a person of ordinary skill in the art. See . The person of ordinary skill in the art is “deemed to read the claim term not only in the context of the particular claim in which the disputed term appears, but in the context of the entire patent,” including the specification and the prosecution history. Id. at 1313. It can also be appropriate to use extrinsic evidencе to determine a term‘s meaning, but “while extrinsic evidence can shed useful light on the relevant art... it is less significant than the intrinsic record in determining the legally operative meaning of claim language.” Id. at 1317 (citations and quotations omitted).

B

The district court construed “virtual machine” as “a computer programmed to emulate a hypothetical computer for applications relating to transport of data.” . That construction is correct, but incomplete. The district court improperly rejected the Appellants’ argument that the “virtual machine” must “process[] instructions expressed in a hardware/operating system-independent language.” Id. at *7. In doing so, the district court noted that dependent claims 5 and 6 of the ‘945 patent expressly require that the “message processor” and “function processor” components of the virtual machine are “imple-mented in the native software code of the microprocessor in the device.” Id. The district court also noted that the specification does not bar the virtual machine from being “written in hardware specific code.” Id. Relying on this, the district court held that the claimed “virtual machine” need not run applications or instructions that are hardware or operating system indepеndent.

The district court‘s construction improperly conflates the claimed virtual machine with applications written to run on the virtual machine. The claimed virtual machine is operating system or hardware dependent because it must communicate directly with the underlying operating system or hardware. But the applications written to run on the virtual machine are not correspondingly dependent because the applications are written to communicate with the virtual machine, not the actual underlying operating system or hardware.

1

The specification and prosecution history establish, and relevant precedent discussing the state of the art at the time of the invention confirms, that at the time the asserted patents were filed, the defining feature of a virtual machine was its ability to run applications that did not depend on any specific underlying operating system or hardware. One problem with the prior art, as the specification notes, was that applications were hardware or operating system dependent. ‘945 patent col. 3 ll. 5–14, 29–34. The patent teaches using a virtual machine to solve this problem because a virtual machine “creates a complete portable environment,” which “allоws programs to operate independent of processor” and allows “[d]ifferent arrangements of hardware [to] be controlled by the same application software.” Id. at col. 3 ll. 34–46; col. 10 ll. 5–7.

That the specification would emphasize this aspect of a virtual machine is not surprising in light of the conventional understanding of the term at the time of the invention. Sun Microsystems, Inc. (Sun) released the famed Java virtual machine in 1996, the year before the earliest possible priority date of the asserted patents. See .1 The Java virtual machine acted as an interpreter between a computer application and the computer‘s underlying operating system and hardware, allowing developers to write one application and run it on multiple different types of computers. ; ; . Sun marketed Java by emphasizing that the virtual machine allowed a develop-

er to “write once, run anywhere.” .

And the prosecution history expressly ties this undisputed conventional understanding of the “write once, run anywhere” Java virtual machine to the patent‘s use of “virtual machine.” During prosecution of the ‘945 patent, the applicant stated that the Java virtual machine was a “conventional” virtual machine that allowed “different incompatible computers (incompatible ‍‌‌‌‌​​​​​​‌​‌‌​‌‌​​​​​​​​‌​​‌​​‌​​​‌​‌​​​​​​‌‌‌​‍hardware and operating systems)” to “be programmed to emulate the same hypothetical computer” so that “[a]pplications” written for that hypothetical computer “are therefore portable to the previously incompatible computers.” JA18849. The applicant explained that the claims describe “an addition to a conventional virtual machine,” not a wholly new structure. Id. In shоrt, nothing in the specification or prosecution history casts doubt on the plain and ordinary meaning of the term “virtual machine.” Cf. (“The inquiry into how a person of ordinary skill in the art understands a claim term provides an objective baseline from which to begin claim interpretation.“). Here, the asserted patents use “virtual machine” in exactly the same way Sun used the term—the patents simply optimize the virtual machine for use on a payment terminal.

2

CardSoft makes two arguments in support of the district court‘s construction. It first argues that the structure of the claims dictates a broader meaning for “virtual machine” because the claims state that the virtual machine “includes” certain “instructions.” ‘945 patent col. 50 ll. 49–53. CardSoft argues that these instructions are akin to applications, and that because the instructions are “include[d]” in the virtual maсhine, and the virtual machine can be operating system or hardware dependent, the instructions can also be operating system or hardware dependent. But this conflates the virtual machine itself with applications (or instructions) running on the virtual machine. The defining characteristic of a virtual machine was, and is, that it acts as an interpreter between applications and the underlying hardware or operating system. That the claimed virtual machine “includes” applications, in the sense that it acts as an interpreter for applications, does not mean that the applications can be hardware or operating system dependent. Such a construction would leave “virtual machine” essentially meaningless.

CardSoft next argues that differentiation of independent claim 1 from dependent claims 7 and 8 of the ‘945 patent mandates a broader construction because these dependent claims state that instructions “do not require translation to the native software code of the microprocessor.” ‘945 patent col. 51 ll. 29–31, 36–37. But claim differentiation is merely a presumption. It is “a rule of thumb that does not trump the clear import of the specification.” ; see also (“[C]laim differentiation is not a hard and fast rule and will be overcome by a contrary construction dictated by the written description or prosecution history.“) (citation and quotation omitted). Because the ordinary meaning of “virtual machine” is clear in light of the specification and prosecution history, claim differentiation does not change its meaning.

IV

VeriFone contends that, applying the correct construction, it is entitled to judgment of no infringement as a matter of law because the accused payment terminals run applications that depend on a specific underlying operating system or hardware. Appellants’ Br. 64-65. CardSoft did not respond to this argument in its responsive brief on appeal. CardSoft recognized the issue: “Appellants argue that, under their construction of ‘virtual machine,’ ‘a ruling of noninfringement [sic] is compelled.‘” Appellee‘s Br. 29. But CardSoft never responded. It instead argued that “[b]ecause Appellants’ construction of ‘virtual machine’ is wrong” the jury‘s verdict should be affirmed. Id.

Arguments that are not appropriately developed in a party‘s briefing may be deemed waived. See (collecting cases); see also (“Failure adequately to brief an issue on appeal constitutes waiver of that argument.“). By failing to respond to VeriFone‘s argument in the briefing, CardSoft has effectively conceded that the accused devices run applications that depend on a specific underlying operating system or hardware. Consequently, we find that CardSoft has waived this argument, and we grant Appellants judgment of no infringement as a matter of law.

V

Because the district court erred by failing to give “virtual machine” its ordinary and customary meaning, we reverse the district court‘s construction of this term. And because CardSoft waived аny argument that Appellants infringe under the correct construction, we grant Appellants judgment of no infringement as a matter of law.

REVERSED

Notes

1
To be sure, the remnants of the railway are also relevant to determining the “highest and best use” of the landowners’ property. See . But the determination of a highest and best use does not obviate the need to determine the fair market value in light of the physical condition of the prоperty. See, e.g., (“The highest and most profitable use for which the property is adaptable is to be considered, not necessarily as to the measure of value, but to the full extent that the prospect of demand for such use affects the market value while the property is privately held.“). On remand from the Supreme Court, CardSoft argues that reliance on precedent describing the conventional undеrstanding of the term “virtual machine” amounts to new factual findings that contradict those of the district court and exalt extrinsic evidence over the intrinsic evidence. Although we imprecisely referred to this as “extrinsic evidence” in our previous decision, there is nothing improper about relying on decisions in previous cases to inform an understanding of a disputed term‘s ordinary meaning, particularly where, as is the case here, that understanding is entirely consistent with the intrinsic record. See . Here, because the intrinsic evidence makes clear that the claimed invention relies on a conventional Java virtual machine, we see no reason to depart from that conventional understanding. Further, the ‍‌‌‌‌​​​​​​‌​‌‌​‌‌​​​​​​​​‌​​‌​​‌​​​‌​‌​​​​​​‌‌‌​‍district court did not make any factual findings, and the mere submission of extrinsic evidence is not enough to mandate deference to a district court‘s claim construction. See supra at 5-6. In short, Teva does not change the outcome of this case.
