Opinion

MEMORANDUM OPINION

KAPLAN, District Judge.

This patent infringement case involves a patent on a system for detecting counterfeit items that is used in tickets used for playing cashless slot machines in casinos, among other things. The matter is before the Court on defendant’s motion for summary judgment dismissing the complaint on the ground that its accused systems do not infringe plaintiffs patent.

I. Facts

A. The Parties

Plaintiff CIAS, Inc. (“CIAS”) owns U.S. Patent No. 5,283,422 (the “'422 patent”), which teaches a system of counterfeit detection. 1

Defendants are Alliance Gaming Corporation and its subsidiary, Bally Gaming, Inc. (collectively, “Alliance”). 2 It is a “leading manufacturer of systems and machines used in the gaming industry.” 3 Among other things, it manufactures and sells two systems that manage all aspects of a casino’s slot machines, including accounting and management functions. 4

B. The '1*22 Patent

After overcoming several rejections based on the cited prior art, 5 the '422 patent issued on February 1, 1994. 6 In connection with infringement litigation unrelated to this case, CIAS requested reexamination on March 30, 1999. 7 A reexamination certificate was issued on October 17, 2000, confirming patentability after amendment of Claim 1 by combining it with the original Claim 8. 8

The parties dispute vigorously the scope and meaning of the '422 patent’s claims, as addressed below. It is undisputed, however, that the '422 patent describes a counterfeit detection system. 9 The system detects counterfeits by assigning identifying information to a finite number of objects and storing that information. 10 When an object later is presented for authentication, the system compares the object’s identifying information to the stored data. 11 If the identifying information either does not appear in the stored data or previously has been presented for authentication, the system determines that the object is counterfeit. 12

Claim 1 of the '422 patent reads in full:

“A counterfeit detection system for identifying a counterfeit object from a set of similar authentic objects, each object in said set having unique authorized information associated therewith comprised of machine-readable code elements coded according to a detectable series, the system comprising:

means at a first facility for storing said authorized information;

means at a plurality of facilities other than said first facility for machine-reading code elements from a similar object and providing information related to the machine-read code elements; means coupled to receive said information related to said code elements machine-read from aid object for at least temporarily storing that information; and

means at said first facility for detecting counterfeits coupled to said storing means and to said means for temporarily storing, said detecting means including a computer programmed to detect a counterfeit from information in said storing means at said first facility and from information received by said means for temporarily storing when information related to code elements machine read from a similar object is different from said authorized information.” 13

Claims 2 through 10 are dependent on Claim 1 and describe various permutations of the system. 14 Claims 11 and 12 describe systems similar to that set out in Claim 1, but with different means of collecting and comparing the unique authorized information. 15 Claims 13 and 14 describe similar systems, but the information associated with each object is “unique randomly selected authorized information [] comprised of machine-readable code elements.” 16 Finally, Claims 15 and 16 describe a method for designating objects as authorized objects by

“randomly selecting m sets of unique authorized information from n sets of unique information, said n sets of unique information being a non-random series and m being substantially less than n, such that no given set of said m sets of unique authorized information is deducible from all or part of the remaining of said m sets of authorized information, n and m being integers and n being greater than one; storing said m sets of authorized information; and applying said m sets of authorized information to respective authorized objects in a machine readable form.” 17

C. Alliance’s Systems

Alliance offers two products, called the Slot Data System (“SDS”) and the Slot Management System (“SMS”), 18 that manage “all aspects of a casino’s slot machines, including accounting and management functions.” 19 They allow players to use “cashless” slot machines by inserting and retrieving electronically-generated tickets redeemable for cash. 20 These paper tickets, called eTickets, 21 are the size of a dollar bill and imprinted with an 18-digit identification number, which appears both numerically and in a standard bar code format. 22 Slot machines read eTickets with “bill validators,” equipment that includes standard bar code readers. 23

While the SDS and SMS systems each produce an 18-digit identification number for every eTicket, they do so in different manners. The SDS system produces a number comprised of five subparts: 24

In contrast, an 18-digit identification number produced by the SMS system 25 is comprised of five digits that identify the machine issuing the eTicket and thirteen digits that are generated by a secret algorithm, that operates on a machine identification number, casino identification number, the date, and the time as its input data. 26

CIAS contends that the SDS system infringes Claims 1 (as amended), 8, 5-7, and 9-12 and that the SMS system infringes Claims 13 and 14.

11. The Standard

Summary judgment is appropriate if there is no genuine issue of material fact and the moving party is entitled to judgment as a matter of law. 27 The moving party has the burden of demonstrating the absence of a genuine issue of material fact, 28 and the Court must view the facts in the light most favorable to the nonmoving party. 29 Where the burden of proof at trial would fall on the nonmoving party, it ordinarily is sufficient for the movant to point to a lack of evidence on an essential element of the nonmovant’s claim. 30 In that event, the nonmoving party must come forward with admissible evidence 31 sufficient to raise a genuine issue of fact for trial or suffer an adverse judgment. 32

When a party moves for summary judgment of non-infringement, the court first determines the meaning and scope of the claims as a matter of law and then compares the construed claims to the allegedly infringing product. 33 A court may, but need not, conduct a Markman hearing to determine the scope of the claims. 34

III. Claim Construction

A. Applicable Law

“It is a ‘bedrock principle’ of patent law that ‘the claims of a patent define the invention to which the patentee is entitled the right to exclude.’ ” 35 Claim terms in a patent normally have their ordinary and customary meanings as understood by those skilled in the relevant art at the time of invention. 36 The understanding of a claim term by one of ordinary skill in the art “provides an objective baseline from which to begin claim interpretation.” 37

The construction inquiry does not take place in a vacuum, as the reading is deemed to take place “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.” 38 Although in some instances the meaning of claim language as understood by a person of ordinary skill in the art may be readily apparent to lay courts, in other cases the analysis may not be as straightforward, as when a patentee uses a term idiosyncratically. 39 In such instances, the court looks to “those sources available to the public that show what a person of skill in the art would have understood disputed claim language to' mean.” 40 Those sources include “the words of the claims themselves, the remainder of the specification, the prosecution history, and extrinsic evidence concerning relevant scientific principles, the meaning of technical terms, and the state of the art.” 41

Of these sources, the Federal Circuit and its predecessors have “long emphasized the importance of the specification in claim construction.” 42 Because the specification’s statutory role is to describe the claimed invention in “full, clear, concise, and exact terms,” 43 it is “the single best guide to the meaning of a disputed term,” always highly relevant, and “[ujsually [] dispositive.” 44 Thus, if a specification reveals a particular definition given to a claim term that differs from its usual meaning, the inventor’s definition controls. 45 Similarly, if a specification includes “an intentional disclaimer, or disavowal, of claim scope,” that too is dispositive. 46

Another intrinsic source that a court should consider is the patent’s prosecution history, which is the “complete record of the proceedings before the PTO and includes the prior art cited during the examination of the patent.” 47 The prosecution history can be helpful evidence of how the PTO and the inventor understood the pat ent. 48 On the other hand, because the prosecution history reflects negotiations between the PTO and inventor, it may lack the specification’s clarity and therefore be less useful for claim construction. 49 All the same, it “can often inform the meaning of the claim language by demonstrating how the inventor understood the invention and whether the inventor limited the invention in the course of prosecution, making the claim scope narrower than it would otherwise be.” 50

Although intrinsic evidence is primary in claim construction, a court may rely also upon extrinsic evidence to “shed useful light on the relevant art.” 51 This includes expert and inventor testimony, dictionaries, and treatises. 52 Expert testimony can be useful in a variety of circumstances, such as

“to provide background on the technology at issue, to explain how an invention works, to ensure that the court’s understanding of the technical aspects of the patent is consistent with that of a person of skill in the art, or to establish that a particular term in the patent or the pri- or art has a particular meaning in the pertinent field.” 53

A court should take care not to rely overmuch on extrinsic evidence, as by its nature it has less of a connection to the specific patent at issue than does intrinsic evidence. 54 Moreover, extrinsic evidence typically is assembled in litigation, when a party can be expected to select evidence that best supports its case and “leav[e] the court with the considerable task of filtering the useful extrinsic evidence from the fluff.” 55 Accordingly, a court may consider extrinsic evidence in claim construction, but should keep its potential flaws in mind and measure it against the yardstick of the intrinsic evidence. 56

Finally, as the Federal Circuit recently noted, “there is no magic formula or catechism for conducting claim construction.” 57 The touchstone is how a person of ordinary skill in the art would understand the claim terms, but a court is not constrained to follow a precise choreographed sequence in conducting its analysis. 58

B. The Terms of the '122 Patent

To resolve Alliance’s motion for summary judgment, it is necessary to construe the terms “unique authorized information,” “machine-readable code elements,” “detectable series,” and “randomly selected” as used in the '422 patent.

1. Unique Authorized Information

Claims 1-12, 15 and 16 all refer to “unique authorized information” associated with individual objects. 59 As CIAS con cedes, 60 neither the claims nor the specification define the term explicitly. 61

CIAS argues that there was no need to define the term, as “unique authorized information” was “intended to and does carry its common and ordinary meaning. The information associated with each object is unique to that object, and it is information that has been authorized by the system.” 62 In other words, “unique authorized information” incorporates any data so designated by the counterfeit detection system— even “a picture of Mickey Mouse with a moustache.” 63

Alliance makes two arguments in favor of a more limited definition. It first contends that the specification requires that the term be construed as referring “merely to a small ‘authorized’ subset of a larger set of ‘valid’ numbers.” 64 As a matter of logic, the “unique authorized information” selected by the system for a given set of objects will be a subset of all possible information that could be so selected. There is no support in the specification, however, for the initial selection of a set of “valid” information from which the “unique authorized information” is then distilled. Alliance points to one section of the specification that, in describing the particular embodiment of casino chips, suggests that casinos, as a practical matter, will need to reserve some coded information for future use. 65 This description of the potential pragmatic needs of one embodiment of the invention, however, cannot be read as a limitation on the claim term itself. 66

Alliance next contends that the inventors disclaimed multi-part information from inclusion in “unique authorized information” during re-examination of the '422 patent. During re-examination, the inventors cited Shoshani, another counterfeit detection patent, as prior art that had not been cited during initial prosecution. 67 The inventors described Shoshani as “teaching] away from the use of serial numbers alone [because they provide inadequate counterfeit protection].” 68 Instead, according to the '422 inventors, Shoshani provides objects with

“an associated pair of numbers []. One number of the pair [ ] is a serially-selected identification number [ ], and the other number of the pair is a randomly-selected control number []. A master list of the associated pairs of numbers applied to objects is stored in mass memory ... [When an object’s pair of numbers is scanned, the device compares that pair with] pairs of numbers stored in the mass memory, and discrepancies are indicated ... Shoshani [ ] teaches the use of a pair of numbers, and not either serial numbers alone or randomly-selected numbers alone.” 69

Alliance argues that by distinguishing Shoshani in this way — by the focus on its use of a pair of numbers as opposed to a serial number or a random number alone — the '422 inventors disclaimed multi-part information from “unique authorized information.”

CIAS responds that Shoshani actually is distinguishable as prior art because “it does not detect when information relating to code elements machine read from a similar object is the same as information previously read from a similar object.” 70 This argument, however, is misplaced, as the issue is not whether the '422 patent should have issued over Shoshani on reexamination, but rather whether the inventors disclaimed multi-part numbers from their patent. Other possible differences between the '422 patent and Shoshani that were not discussed by the inventors at that time are therefore of no present moment.

CIAS argues further that Shoshani does not treat the pair of numbers as a unit, but as separate numbers: “To check authenticity, it first looks at the serial number. Then it checks the control number to see if it matches the corresponding control number for that serial number stored in a computer. Accordingly, the two numbers in Shoshani are used separately and not together as either a detectable series or a random number.” 71

Again, while this may be an accurate description of how Shoshani actually works, the question here is what the inventors disclaimed during re-examination. The inventors there characterized Shosha-ni differently, stating that it “teaches the use of a pair of numbers, and not either serial numbers alone or randomly-selected numbers alone.” 72 They did not state that Shoshani used the two numbers separately, but instead implied that the patent used them together, as opposed to “serial numbers alone or randomly-selected numbers alone.” The inventors requested re-examination because of their failure to disclose Shoshani as prior art during the initial prosecution, 73 and so the context of their description of Shoshani was their interest in distinguishing it from the '422 patent. With that framework in mind, the implication of the inventors’ description is that they understood and claimed the '422 patent, in contrast to Shoshani, to use either serial numbers alone or randomly-selected numbers alone. 74

Despite being secondary to the specification, prosecution history can demonstrate “how the inventor understood the invention and whether the inventor limited the invention in the course of prosecution, making the claim scope narrower than it would otherwise be.” 75 A competitor, “reading the prosecution history, would reasonably conclude” that the '422 inventors had restricted their claims to information of a single type and thus had given up multi-type information. 76 On the basis of the re-examination statements of the inventors in distinguishing Shoshani, therefore, the term “unique authorized information” excludes information other than serial information alone or randomly-selected information alone.

Against this construction, CIAS argues that the full language of Claim 1 makes “unique authorized information” open-ended.

“The '422 patent claims ‘unique authorized information ... comprised of ma-

the patent. Furthermore ... the prosecution history was created by the patentee in attempting to explain and obtain the patent.”). chine readable code elements coded according to a detectable series. The claim language has no exclusion of multi-part information. To the contrary, use of the word “comprised” expressly means that the ‘unique authorized information’ may include something in addition to the detectable series.” 77

In other words, Claim l’s description of “unique authorized information” includes not just machine readable elements coded according to a detectable series, but also any additional information that the system selects. Thus, argues CIAS, multi-part or -type information is included.

As an initial matter, this argument does not address the re-examination history detailed above, as the Claim 1 language is original to the initial prosecution and so subject to the inventors’ disclaimer during re-examination. Accordingly, even if CIAS were correct as to the language in Claim 1, the conclusion would remain the same.

Further, despite the Court’s invitation, 78 CIAS was unable to locate binding case law holding that “comprised of’ is an open-ended term, rather than a limiting one. Instead, both parties’ searches, as well as the Court’s, indicate that there is no consensus in the Federal Circuit as to the meaning of this phrase. 79 In the absence of such precedent, of any indication in the patent itself as to the phrase’s meaning, and of any external evidence offered by the parties, the Court adheres to the ordinary and customary meaning of “eom-prised of’ as a limiting description of composition. 80 This construction preserves the distinction between “comprised of’ and “comprising,” the latter of which in fact is a patent term of art when used in a transitional phrase, meaning “including, but not limited to.” 81

Accordingly, the Court construes “unique authorized information” to mean information associated with each object, unique to that object and authorized by the '422 patent’s system, but excluding information other than serial information alone or randomly-selected information alone.

2. Machine-Readable Code Elements

Claims 1-14 describe how the objects are associated by the system with unique authorized information comprised of “machine-readable code elements.” Alliance contends that the phrase is limited to directly-encoded binary numbers, while CIAS argues that it refers to any code that can be separated into parts and automatically obtained from objects.

The specification defines “machine-readable” as “used in a broad sense and [] meant to encompass techniques, methods and apparatus for automatically obtaining from objects information applied thereto or associated therewith.” 82 Since the specification here acts explicitly as a dictionary, its definition of “machine-readable” controls. 83

“Code elements” are also defined in the specification, albeit less concretely, as “digits, characters, positions, places, pulses, signals, etc.” 84 This list of examples is non-exclusive, which suggests that the phrase is intended to refer broadly to any individual part of a code. Defendants argue that the specification describes only embodiments that use binary code, but again, a patent is not limited to one embodiment if its terms, as defined, include a broader scope. 85 Here, the specification describes numerous kinds of ' code elements, not just binary forms.

The specification is “the single best guide to the meaning of a disputed term.” 86 Where, as here, it provides explicit definitions, the Court must follow its direction. 87 Accordingly, the phrase “machine-readable code elements” is construed as individual parts of a code (1) that can be separated into parts and (2) that can be automatically obtained from objects.

3. Detectable Series

Claims 1-12 describe each particular object as being associated with unique authorized information comprised of machine-readable code elements “coded according to a detectable series.” 88 The specification does not define “detectable series” and discusses “series” in the context of a binary embodiment. 89 While the inventors did not define “detectable series” explicitly during prosecution, they listed “sequential serial numbers” as an example in several places. 90 Further, they contrasted the term with the results of “secret algorithms” and noted that in McNeight, which uses a secret algorithm as its means of counterfeit detection, “serial numbers are of no value.” 91

Against this intrinsic evidence, CIAS offers its expert’s opinion that, to one skilled in the art, “detectable series” means “information in which a pattern, relationship, or arrangement may be detected through examination of a practical number of samples in the context in which the invention is used.” 92

Alliance objects that the expert’s opinion is unsupported and argues that the phrase has no meaning in the art. 93 Without pointing out what is erroneous about the offered definition, or what aspects, if any, are contradicted by the patent, it concludes that the term must be limited to the binary embodiments described in the specification. 94 Alliance’s own expert, however, despite professing confusion, uses the phrase without difficulty as part of his own analysis of the '422 patent. 95 This demonstrates that to one skilled in the art — a category which Alliance certainly concedes includes its expert — the phrase has mean ing. Moreover, and once again, a patent drawn to encompass multiple possible embodiments is not limited to a single exemplar from the specification. 96

Accordingly, the term “detectable series” is construed to mean “information in which a pattern, relationship, or arrangement may be detected through examination of a practical number of samples in the context in which the invention is used.” This definition is consistent with the inventors’ description in the prosecution history, including the inclusion of “sequential serial numbers” and the exclusion of the results of “secret algorithms.” 97

A Randomly Selected

The final term requiring construction is “randomly selected,” which appears in Claims 13 and 14. 98 Those claims describe each particular object as being associated with unique “randomly selected” authorized information comprised of machine-readable code elements. 99 The term is thus substituted in Claims 13 and 14 for the term “detectable series” in Claims 1-12. 100 rp^g Specification does not define the term. 101

Alliance contends that the term means exactly what it says: selection according to a random process, without any pattern or predictability whatsoever, as in a generator that selects digits based on cosmic noise. 102 It argues further that the term cannot include pseudo-random selection; which is apparent randomness that has been generated purposefully, as by a computer algorithm or other program. 103 CIAS does not disagree with Alliance’s definition of pseudo-random or argue that a computer or algorithm can generate anything besides a pseudo-random number. It contends, however, that a person of ordinary skill in the art understands “randomly selected” to include information selected by both true and pseudo-random means. 104

Each side has provided expert testimony to support its position, but neither expert provides additional support, making their assertions less helpful. 105 The specification is silent. Alliance makes the somewhat convoluted argument that because the specification does not teach the use of an algorithm for information selection— which no party disputes would be a pseudo-random selection process — “randomly selected” should be construed to refer only to true random selection. 106 But Alliance does not argue, nor could it, that the use of an algorithm is the only means of pseudo-random selection, so that its absence necessitates the exclusion of pseudo-random selection altogether.

Each side points to prior art to support its position. Alliance cites to Shoshani, which explicitly defines “ ‘random numbers’ [to mean] true random numbers, as well as Pseudo-random numbers.” 107 Alliance argues that Shoshani must have included this definition because the normal meaning of “random” as excluding pseudo-random would otherwise apply. In other words, Shoshani had to provide its own definition to bring pseudo-random within “random.” In turn, CIAS cites to U.S. Patent No. 6,048,269 (“Burns”), a slot machine system patent, which discloses use of a “unique random number” that nonetheless is generated by a computer and therefore pseudo-random. 108

Finally, Alliance argues further that a sibling patent by the same inventors, U.S. Patent No. 5,367,148 (the “'148 patent”), 109 recognizes that “random” does not include pseudo-random. A court may look to a sibling patent and the common application for the meaning of shared terms used in similar contexts. 110 Both the '148 and '422 patents include the term “randomly selected” in the context of choosing information for counterfeit detection. 111

The '148 patent describes a system in which “[e]ach random portion may contain one or more randomly selected digits. A random number generator may be used which may, e.g., randomly select digits based on cosmic noise.” 112 The '148 specification goes on to state, “[w]ith the applicants’ random technique, the problems and worries described above for traditional serial numbers and ID numbers in accord with a secret algorithm are simply avoided.” 113 This distinction between the results of the '148 “randomly selected” technique and those of pseudo-random algorithmic methods indicates that the '148 technique is a true random one and, therefore, that the '148/'422 inventors used “random” to mean true random.

Further, during prosecution of the '148 patent, the inventors described another patent, Zoltai, as disclosing a system in which

“[so-called] random process units at a central and remote location output the same code in response to the same unit. The ‘random’ in [Zoltai’s so-called] random process units is a misnomer. If both [Zoltai] units are truly random generators, there should be an infinitesimal or no chance for them both to output the same number at the same time ... [In

(which may very well include slot machines other than those described in Telnaes) cannot circumscribe the Telnaes language itself. See Storch Decl. ¶ 15. fact,] Zoltai [elsewhere] discloses that the patterns are not random but ‘predetermined from within the units’ ... Thus, [Zoltai does] not disclose the use of random numbers.” 114

Thus, the '148 inventors took prior art to task for using the term “random” incorrectly to include pseudo- or non-random information. This correction further clarifies that when the inventors themselves used “randomly selected” in the '148 patent, they referred to true random selection.

Since the '148 and '422 patents are siblings, the identical claim language of the former can be considered in construing the '422 patent’s claims. 115 Although it is a close question, the Court concludes that “randomly selected,” as used by the '148 and '422 inventors, refers to true and not pseudo-random selection.

TV. Infringement

“[W]hoever without authorization makes, uses, offers to sell, or sells any patented invention, within the United States or imports into the United States any patented invention during the term of the patent therefor [directly] infringes the patent.” 116 To establish direct infringement, a plaintiff must prove that one or more claims of the patent read on the accused device literally or under the doctrine of equivalents. 117 Literal infringement requires that each and every limitation set forth in a claim appear in an accused product. 118 Under the doctrine of equivalents, however, “[t]he scope of a patent is not limited to its literal terms but instead embraces all equivalents to the claims described.” 119 It thus permits the patentee to claim “insubstantial alterations that were not captured in drafting the original patent claim” and prevents in-fringers from pointing to inconsequential additions to escape literal infringement. 120

A. The SDS System

CIAS contends that the SDS system infringes Claims 1 (as amended), 3, 5-7, and 9-12 of the '422 patent. All of those claims have in common the requirement that the counterfeit detection system provide for each object to have “unique authorized information associated therewith comprised of machine-readable code elements coded according to a detectable series.” 121

It is undisputed that Alliance’s SDS system produces for each eTicket an identification number comprised of five subparts: ticket type, property identifier, machine number, ticket number, and unique ticket identifier. 122 The ticket number is a 5-digit serial number ranging from 00001 to 99999. 123 The unique ticket identifier, in contrast, is a pseudo-random number, generated by a secret computer algorithm that uses the preceding ticket type, property identifier, machine, and ticket numbers as its inputs. 124

This composite nature of the SDS eTick-et identification number takes it outside the construed claim term “unique authorized information.” As construed, “unique authorized information” excludes information other than serial information alone or randomly-selected information alone. Here, the SDS eTicket identification number does include a serial number, the five-digit ticket number, but includes also three non-serial, non-random numbers and the pseudo-random unique ticket identifier. This combination of data means that the SDS system does not read literally on the “unique authorized information” element of Claims 1, 3, 5-7, and 9-12, as it does not use serial information alone, nor randomly-selected information at all. Nor does the doctrine of equivalents apply, as the '422 inventors narrowed this claim during reexamination to exclude information other than serial information alone or randomly-selected information alone. They cannot now recover that surrendered subject matter by means of the doctrine of equivalents. 125

Further, and for much the same reason, the SDS system does not use information “comprised of machine-readable code elements coded according to a detectable series.” As construed, a detectable series is “information in which a pattern, relationship, or arrangement may be detected through examination of a practical number of samples in the context in which the invention is used.” Although an individual SDS eTicket identification number contains a serial number subpart (the ticket number), it is undisputed that the SDS system does not produce eTickets with identification numbers from which a pattern may be detected through examination of a practical number of samples. The final subpart of an SDS eTicket identification number is generated by a secret algorithm, which produces numbers that appear to be random. 126 CIAS concedes that this final part of an SDS eTicket identification number is not a detectable series. 127 Indeed, the '422 inventors distinguished between a detectable series and the results of such an algorithm during prosecution. 128 Since part of the SDS eTicket identification number is not a detectable series, the entire numbers also are not a detectable series, and so the SDS system does not include that element.

Accordingly, the SDS system does not infringe Claims 1, 3, 5-7, or 9-12 either literally or under the doctrine of equivalents.

B. The SMS System

CIAS contends that the SMS system infringes Claims 13 and 14 of the '422 patent, both of which require the use of “unique randomly selected authorized information” to identify objects. 129 “Randomly selected” has been construed to exclude pseudo-random selection and to refer to true random selection only.

It is undisputed that the SMS 18-digit eTicket identification number is comprised of five digits that identify the machine issuing the eTicket and thirteen digits that are generated by a secret algorithm, which uses a machine identification number, casino identification number, the date, and the time as its input data. 130 It is undisputed also that the SMS secret algorithm, like all algorithms, generates pseudo-random numbers. 131 As the term “randomly selected” from Claims 13 and 14 has been construed to refer to true random selection only, the SMS system thus does not literally infringe those claims. CIAS argues that the doctrine of equivalents should apply here, as Alliance has conceded that pseudo-random information presents “the appearance of randomness,” arguably the crucial deterrence function of a counterfeit detection system. 132 Alliance does not address this argument, but since the SMS system does not infringe Claims 13 and 14 for an independent reason, it is ultimately an academic point.

As with the SDS system, the SMS system does not use “unique ... authorized information,” as that term has been construed to exclude information other than serial information alone or randomly-selected information alone. It is undisputed that the SMS 18-digit eTicket identification number is comprised of five digits that identify the machine issuing the eTicket and thirteen digits that are generated by a secret algorithm, which uses a machine identification number, casino identification number, the date, and the time as its input data. 133 As with the SDS system, this multi-type information (part serial, part non-serial) contradicts the “unique ... authorized information” element of Claims 13 and 14, as it is neither serial information alone nor randomly-selected information at all. Again, since the inventors voluntarily narrowed the scope of the patent during re-examination to exclude information other than serial information alone or randomly-selected information alone, the doctrine of equivalents does not apply. 134

Accordingly, the SMS system does not infringe Claim 13 or 14 either literally or under the doctrine of equivalents.

V Conclusion

Alliance's motion for summary judgment dismissing the complaint is granted. As this moots defendants’ counterclaim, the action is dismissed in its entirety.

See generally id.., Exhibit N ("Telnaes Patent”). It is not clear from the Telnaes claims or specification, however, whether the patent relies on a true or pseudo-random number generator, and thus it is also not clear what Telnaes meant by "random.” Although Mr. Storch, one of the '422 patent inventors, states that he is familiar with the "type of slot machines described in” the Tel-naes patent and that they do not use true random number generators, his professed experience with that genre of slot machines

See Festo, 535 U.S. at 733-34, 122 S.Ct. 1831 (“The doctrine of equivalents allows the patentee to claim those insubstantial alterations that were not captured in drafting the original patent claim but which could be created through trivial changes. When, however, the patentee originally claimed the subject matter alleged to infringe but then narrowed the claim in response to a rejection, he may not argue that the surrendered territory comprised unforeseen subject matter that should be deemed equivalent to the literal claims of the issued patent ... Prosecution history es-toppel ensures that the doctrine of equivalents remains tied to its underlying purpose. Where the original application once embraced the purported equivalent but the pat-entee narrowed his claims to obtain the patent or to protect its validity, the patentee cannot assert that he lacked the words to describe the subject matter in question.”).
