Centillion Data Systems, LLC (Plaintiff) initiated legal action against Convergys Corporation, Qwest Communications International, Inc., and Qwest Corporation (collectively, Defendants). The United States District Court for the Southern District of Indiana addressed the Defendants' Motion to Stay and Motion for Summary Judgment regarding the validity of Centillion's U.S. Patent No. 5,287,270 (the '270 patent). Defendants argued that the patent is invalid under 35 U.S.C. § 112 due to a lack of written description and enablement, claiming that Centillion's interpretation of "as specified by the user" is unsupported by intrinsic evidence and lacks expert support for enabling practice of the invention.

The '270 patent pertains to billing systems enabling service customers to manage usage and cost information from service providers like telecommunications companies. The Court previously interpreted the claim term "as specified by the user" within the context of claim 1, which details a system for presenting actual service costs to users. Defendants contended that this term necessitates that summary reports be "pre-selected by the service customer," supported by Dr. Dunsmore's assertion that it implies active selection by the user. Ultimately, the Court denied the Defendants' Motion for Summary Judgment, indicating that the arguments presented did not warrant invalidation of the patent.

Defendants argue that the term in question lacks specification support and should be interpreted using its plain meaning rather than adopting Centillion's proposed interpretation, even if it risks invalidating the claim due to insufficient written description. Centillion contends that the term should mean "specific to the user," emphasizing an alternative definition of "specify" from Webster's dictionary, which aligns with the specification indicating that transaction records are sorted by specific users before summary report generation. Centillion asserts that this interpretation is consistent with the claim's original language prior to the inventor's modification, which added "specified by." Additionally, Centillion points out that the inventors' language in other claims supports their interpretation of "as specified by the user." The Court, however, agrees with Defendants that the plain meaning necessitates that the user selects the characteristics of the summary reports. It finds Centillion's proposed interpretation alters the verb and subject of the phrase, effectively rewriting the claim, which the Federal Circuit prohibits. The Court also dismisses Centillion's arguments regarding the influence of other claims or the specification, clarifying that the phrase does not require direct user control over data processing, as the specification allows for third-party involvement in data processing.

Third-party processors or the service provider itself may perform specified functions related to preprocessed summary reports. The phrase "as specified by the user" mandates that the service customer must choose or define the nature of these reports. The Court clarifies that this phrase explicitly means that the service customer selects the report characteristics. Centillion argues against the defendants' interpretation, stating that their definition improperly requires users to pre-select summary reports for preprocessing, which lacks support in the intrinsic evidence. Moreover, the defendants' definition, suggesting users must select reports in the preprocessing stage prior to customer transfer, is also unsupported by the specification and impractical.

Summary judgment is described as an essential component of federal procedural rules, aimed at ensuring a fair and efficient resolution of legal actions. It is governed by Federal Rule of Civil Procedure 56(c), which allows for judgment if there are no genuine issues of material fact, supported by pleadings and evidence. The burden lies with the nonmoving party to demonstrate that genuine issues exist, rather than relying solely on pleadings. The Court does not have the obligation to search for evidence to oppose a summary judgment motion; it is the responsibility of the nonmoving party to identify such evidence. When the moving party meets the Rule 56 criteria, summary judgment is required. The Court must interpret undisputed facts in favor of the nonmoving party and consider disputed evidence from their perspective, with only disputes affecting the case outcome preventing summary judgment.

Irrelevant facts do not impede summary judgment, even if disputed, as established in Clifton v. Schafer. If the nonmoving party does not demonstrate an essential element of their case, summary judgment must be granted to the moving party, as per Ortiz v. John O. Butler Co. Section 112.1 of 35 U.S.C. requires that a patent's specification must include a written description that enables a person skilled in the relevant field to make and use the invention, detailing the best mode contemplated by the inventor. This requirement ensures the inventor had the necessary information and discloses the invention to the public (Space Sys./Loral Inc. v. Lockheed Martin Corp.). The description must provide sufficient detail to meet statutory standards, even omitting known information to the public (Lockwood v. Am. Airlines, Inc.). Additionally, the specification must enable skilled individuals to utilize the full scope of the invention without "undue experimentation" (Nat'l Recovery Techs. Inc. v. Magnetic Separation Sys. Inc.). A patent is presumed valid, placing the burden on the defendants to demonstrate with clear and convincing evidence that the requirements of 35 U.S.C. 112.1 are unmet (Sitrick v. Dreamworks, LLC). The question of whether a claim meets these requirements is a legal one, based on factual determinations.

Defendants contend that Centillion admitted a lack of written description and enablement for the term "as specified by the user." The Court disagrees, clarifying that Centillion's admission, if any, did not imply that user control was necessary for the data processing system. The Court indicated that user input could occur prior to third-party processing of the data, undermining Defendants' argument. The Court found that Centillion's experts had raised sufficient factual questions to contest Defendants' Motion for Summary Judgment, noting that the specification describes a billing system enabling customers to manipulate usage and cost information, alongside discussing other less satisfactory data manipulation methods.

The patent reveals that the system can be utilized by the service customer, service provider, or a third-party processor, indicating that communication between the service customer and user of the patented system is essential for addressing service needs. In the context of claim 1, the system must incorporate input from the service customer to ensure the generated summary reports reflect the customer's priorities. Expert testimony from Daniel Briere supports that individuals skilled in the field would recognize that customers typically specify the reports they require, including specific billing details like accounting codes, which was a common practice at the time of the invention. The patent outlines the necessity for customer-provided information for optimal system performance, emphasizing that large-volume service customers needed an effective way to analyze call-detail and telecommunications data. It describes the subscription process for services and the importance of reconciling electronic billing with paper bills. The system is designed to accumulate data for tailored reports and graphs accessible via personal computers, which inherently requires user input. The detailed description of the preferred embodiment underscores the necessity of operator input during data retrieval. Thus, the Court concludes that sufficient evidence exists to satisfy the written description and enablement requirements of 35 U.S.C. § 112, leading to the denial of the Defendants' Motion for Summary Judgment. Consequently, the Defendants' Motion to Stay is also denied as moot.
