DataTreasury Corporation v. Fiserv, Inc.

Case Overview and Background

This litigation is a key chapter in a long-running, industry-wide patent enforcement campaign by DataTreasury Corporation, a Texas-based company often characterized as a patent assertion entity (PAE). Since 2002, DataTreasury has sued dozens of banks and financial technology companies, alleging that modern electronic check and document processing systems infringe on its patents. This specific case, filed in 2013, targets Fiserv, Inc., a major multinational financial technology and services corporation, along with its client banks. Fiserv provides a wide array of services to financial institutions, including payment processing, electronic funds transfers, and check processing solutions. The lawsuit alleges that Fiserv's check capture and processing systems—core to modern banking operations—infringe DataTreasury's intellectual property.

The dispute centers on two patents, both titled "Remote Image Capture with Centralized Processing and Storage": U.S. Patent No. 5,910,988 ('988 patent) and U.S. Patent No. 6,032,137 ('137 patent). The '988 patent describes a broad system for capturing data from paper documents at remote locations and sending it to a central subsystem for processing and storage. The '137 patent is more specifically directed to a system for imaging and processing data from paper checks. Together, DataTreasury has argued these patents cover the foundational technology for digital check imaging and clearing, which became ubiquitous after the passage of the Check Clearing for the 21st Century Act ("Check 21 Act") in 2003. The case was filed in the U.S. District Court for the Eastern District of Texas, a venue historically known for its plaintiff-friendly reputation, fast trial schedules, and expertise in handling complex patent cases.

This litigation is notable for several reasons. It represents a mature stage in one of the most significant and lucrative patent assertion campaigns in the financial services industry, with DataTreasury having reportedly collected over $350 million in licensing fees from previous defendants. The case against Fiserv is part of a wave of suits filed simultaneously against other major financial service providers like Fidelity National Information Services (FIS) and Jack Henry & Associates, signaling a concerted effort to license the remaining major players. The case is also linked to parallel validity challenges at the U.S. Patent and Trademark Office. Defendants in these cases, including Fiserv, initiated Covered Business Method (CBM) and inter partes review (IPR) proceedings in an attempt to invalidate the patents at the Patent Trial and Appeal Board (PTAB). These PTAB proceedings ultimately proved successful for some defendants, with the Federal Circuit later affirming the invalidity of the patents under the Supreme Court's Alice decision on patent eligibility.

Key Developments and Outcome

2013-05-28: Filing & Initial Pleadings
DataTreasury Corporation filed a patent infringement lawsuit against Fiserv, Inc., and several of its client banks in the Eastern District of Texas (Case 2:13-cv-00431). The complaint alleged that Fiserv's check processing systems and services infringed on U.S. Patent Nos. 5,910,988 and 6,032,137. This suit was one of three similar actions filed simultaneously against other financial technology service providers, including Jack Henry & Associates and Fidelity National Information Services (FIS), and their respective client banks.

2014: Parallel PTAB Proceedings and Motion to Stay
In response to the litigation, Fiserv and the other service providers, Jack Henry and Fidelity National, filed petitions with the Patent Trial and Appeal Board (PTAB) for inter partes review (IPR) and covered business method (CBM) review of the asserted patents.

• Fiserv Petitions: On March 12, 2014, Fiserv filed petitions for CBM review of the '988 patent (CBM2014-00087) and the '137 patent (CBM2014-00088).
• Other Defendants' Petitions: Fidelity National and Jack Henry also filed their own CBM and IPR petitions against the patents around the same time.

Given the institution of these PTAB reviews, which created a significant likelihood that the patents could be found invalid, the defendants in the district court case moved to stay the litigation.

2014-08-14: District Court Proceedings Stayed
The U.S. District Court for the Eastern District of Texas granted the defendants' motion and stayed the case pending the outcome of the various PTAB proceedings. This order (Docket Entry 616) effectively paused all district court activity, including any potential claim construction (Markman) hearings or summary judgment motions, pending the PTAB's validity determinations.

2015-2016: PTAB Invalidates Patents
The parallel PTAB reviews proved fatal to DataTreasury's patents. In a series of final written decisions, the PTAB found the challenged claims of both the '988 and '137 patents unpatentable.

• 2015-04-29: In a key decision, the PTAB found the claims of the DataTreasury patents invalid because they were directed at an abstract idea, a significant victory for the financial services industry.
• 2015-07-08: In another proceeding initiated by Jack Henry, the PTAB found claims 42 and 43 of the '137 patent unpatentable as anticipated.

2016: Federal Circuit Appeal and Final Resolution
DataTreasury appealed the PTAB's adverse decisions to the U.S. Court of Appeals for the Federal Circuit. Fiserv and the other defendants cross-appealed.

• 2016-10-05: In the appeal from the CBM review initiated by Fidelity National, the Federal Circuit summarily affirmed the PTAB's decision, cementing the invalidity of the DataTreasury patents (DataTreasury Corp. v. Fidelity Nat'l Info. Svcs., No. 16-1046). This decision was a major blow to DataTreasury's entire litigation campaign.
• 2016-10-13: Following the decision in the Fidelity National appeal, the Federal Circuit dismissed as moot DataTreasury's appeal against Fiserv (DataTreasury Corp. v. Fiserv, Inc., No. 16-1229, 16-1230). With the patents already confirmed as invalid in a parallel case, there was no longer a live controversy to be decided between DataTreasury and Fiserv.

Outcome: Dismissal of Litigation
The Federal Circuit's affirmation of the PTAB's invalidity findings was the definitive end for this litigation. With the asserted patents invalidated, DataTreasury had no basis to continue its infringement claims against Fiserv. Consequently, the stayed district court case was dismissed. The successful use of the CBM review process by Fiserv and its co-defendants allowed them to invalidate the patents at the PTAB, a faster and more cost-effective venue than district court, leading to the complete termination of the infringement suit.

Summary of Findings:

Plaintiff DataTreasury Corporation was primarily represented by the law firm Nix Patterson & Roach LLP (now Nix Patterson, LLP), which has a long history of representing DataTreasury in its extensive patent litigation campaigns against the financial industry. Attorneys from this firm served as lead counsel.

The counsel of record was explicitly identified in the filings for the appeal at the U.S. Court of Appeals for the Federal Circuit (DATATREASURY CORPORATION v. FISERV, INC., No. 16-1229). In that proceeding, Edward K. Chin of the Longview-based Albritton Law Firm argued the case for DataTreasury. He was supported by Derek Tod Gilliland of Nix Patterson & Roach LLP and Christian John Hurt, a Dallas-based attorney. The use of the Albritton Law Firm is consistent with the common practice of retaining local counsel in the Eastern District of Texas.

While specific notices of appearance from the initial 2013 district court filing were not available in the search results, the appellate record provides a reliable list of the key attorneys who managed the litigation against Fiserv.
