MPHJ Technology Investments, LLC v. Lexmark International, Inc.

Case Overview and Background

This litigation was part of a large-scale, aggressive patent assertion campaign by Plaintiff MPHJ Technology Investments, LLC, a non-practicing entity (NPE) widely described as a "patent troll." The defendant, Lexmark International, Inc., is a major operating company that manufactures and sells printers and other imaging products. MPHJ acquired a portfolio of patents related to network scanning in 2012 and subsequently sent thousands of demand letters to small and large businesses across the United States, asserting that their use of common "scan-to-email" functionality on office equipment infringed its patents. Lexmark, as a manufacturer of multifunction printers with this capability, was a direct target of the litigation campaign.

The lawsuit, filed in the U.S. District Court for the Southern District of California, asserted U.S. Patent No. 6,185,590. This patent, titled "Method and system for tracking and billing for resource usage on a network," generally claims a method for monitoring the use of a network resource, such as a scanner or printer, and associating that usage with a specific user or account for billing purposes. MPHJ's infringement contention was that Lexmark's devices, which allow users to scan documents and send them to an email address over a network, practiced the methods claimed in the patent. The Southern District of California was a notable venue as it was part of a Patent Pilot Program designed to enhance judicial expertise in patent cases.

The case is highly notable not for a specific ruling within this docket, but for its connection to MPHJ's broader campaign, which became a poster child for patent litigation abuse. MPHJ sent over 16,000 demand letters, often to small end-users of scanner technology, demanding license fees of around $1,000 per employee. This strategy provoked a significant backlash, leading to investigations and legal actions by multiple state attorneys general and a landmark consumer protection enforcement action by the Federal Trade Commission (FTC). The FTC action, settled in November 2014, barred MPHJ from using deceptive threats and misrepresentations in its demand letters. In a coordinated defensive effort, major scanner manufacturers, including Lexmark, Ricoh, and Xerox, challenged MPHJ's patents through Inter Partes Review (IPR) proceedings at the Patent Trial and Appeal Board (PTAB), which ultimately led to the invalidation of claims in related MPHJ patents.

On February 26, 2013, Defendant Lexmark International, Inc. filed an answer and counterclaim in this patent infringement case. In its answer, Lexmark denied infringing the patent-in-suit and asserted several affirmative defenses, including non-infringement, invalidity, and failure to state a claim. Lexmark also filed a counterclaim seeking a declaratory judgment that it does not infringe the patent-in-suit and that the patent is invalid. In its counterclaim, Lexmark alleged that the patent is invalid for failing to comply with one or more of the requirements of 35 U.S.C. §§ 101, 102, 103, and/or 112. Lexmark also alleged that it has not infringed and does not infringe any valid and enforceable claim of the patent, either literally or under the doctrine of equivalents.

Motion to Dismiss for Failure to State a Claim filed by Lexmark International, Inc.. (Attachments: # 1 Proposed Order)(Haire, John) (Entered: 02/26/2013).

MPHJ moved to voluntarily dismiss the case against Lexmark without prejudice on August 19, 2013. The court granted the motion and dismissed the case on August 26, 2013. In its motion, MPHJ stated that it had "determined that it is not financially feasible to pursue this litigation at this time." The dismissal came shortly after the Federal Trade Commission (FTC) had sent letters to MPHJ and its counsel questioning their litigation tactics and demanding information about their licensing campaign. MPHJ had sent letters to thousands of small businesses demanding license fees of $1,000 per employee for using common office equipment with scan-to-email functionality. The FTC's investigation and the negative publicity surrounding MPHJ's tactics are widely believed to have contributed to the dismissal of this and other lawsuits filed by MPHJ.

Court filings show that on August 19, 2013, MPHJ filed a notice of voluntary dismissal without prejudice. The court subsequently entered an order of dismissal on August 26, 2013, closing the case. This dismissal followed a trend of MPHJ dismissing numerous similar lawsuits it had filed against other defendants around the same time. The dismissals coincided with increasing scrutiny of MPHJ's business practices by state attorneys general and the Federal Trade Commission.

On May 13, 2014, the Federal Trade Commission (FTC) announced a final order settling charges against MPHJ Technology Investments, LLC and its law firm, Farney Daniels, P.C., for using deceptive and unfair tactics in their patent licensing campaign. The FTC alleged that MPHJ and its lawyers sent letters to thousands of small businesses across the country falsely claiming that they were infringing an MPHJ patent and threatening them with lawsuits if they did not pay licensing fees of $1,000 per employee. The settlement prohibits MPHJ and its lawyers from making false or unsubstantiated claims in the future and requires them to have a good faith basis for any future patent infringement claims.

In January 2013, the Attorney General of Vermont sent a letter to MPHJ's counsel, demanding that they cease their licensing campaign in the state, calling it "abusive" and "deceptive." Other states followed suit. This state-level pressure, combined with the FTC's investigation, created a hostile environment for MPHJ's litigation campaign.

MPHJ Technology Investments, LLC v. Lexmark International, Inc. was one of over a dozen lawsuits MPHJ filed in late 2012 against various technology companies. The company's business model involved sending out thousands of demand letters to small businesses, followed by lawsuits against larger companies, seemingly to pressure the smaller companies into settling. The widespread negative media attention and government scrutiny ultimately led to the unraveling of the campaign.

There is no indication in the court docket or in public reporting that the case against Lexmark reached the claim construction (Markman) stage. The case was dismissed relatively early in the litigation process, prior to significant motion practice or a Markman hearing.

IPR2014-00293, Lexmark Int'l, Inc. v. MPHJ Tech. Invs., LLC, Patent 6,185,590. Petition Filed 12/20/2013. The Patent Trial and Appeal Board (PTAB) declined to institute an inter partes review (IPR) of the '590 patent. The PTAB found that Lexmark had not established a reasonable likelihood that it would prevail in showing that the challenged claims were unpatentable. However, this IPR was filed after the district court case against Lexmark had already been dismissed.

Despite the earlier dismissal of the district court case, Lexmark proceeded with its IPR petition against the '590 patent. The PTAB's decision not to institute the IPR was a setback for those challenging the validity of the patent, but it had no direct impact on the already-terminated litigation between MPHJ and Lexmark.
https://www.law360.com/articles/[549448](/patent/549448)/ptab-won-t-review-mphj-patent-in-lexmark-challengeIn its litigation against Lexmark International, Inc., MPHJ Technology Investments, LLC saw its case terminate early amid significant government scrutiny of its broader litigation campaign. The case did not reach substantive pre-trial milestones like claim construction before its dismissal.

Filing and Initial Pleadings

MPHJ Technology Investments, LLC filed a complaint for patent infringement against Lexmark International, Inc. on 2012-12-17 in the Southern District of California. The lawsuit alleged that Lexmark's printers and multi-function products with scan-to-email capabilities infringed U.S. Patent No. 6,185,590, entitled "Virtual Office Management System And Method."

On 2013-02-26, Lexmark responded by filing an answer and a motion to dismiss for failure to state a claim. In its answer, Lexmark denied infringement and asserted affirmative defenses, including non-infringement and invalidity. Lexmark also filed a counterclaim seeking a declaratory judgment that it did not infringe the '590 patent and that the patent was invalid under 35 U.S.C. §§ 101, 102, 103, and/or 112.

Regulatory Scrutiny and Voluntary Dismissal

The case against Lexmark was part of a much larger litigation campaign by MPHJ, which involved sending thousands of demand letters to small businesses, demanding license fees of $1,000 per employee for using standard office equipment. This campaign attracted the attention of state attorneys general and the U.S. Federal Trade Commission (FTC).

In the face of mounting legal and regulatory pressure, MPHJ began to unravel its litigation campaign. On 2013-08-19, MPHJ filed a notice of voluntary dismissal without prejudice in the Lexmark case, stating it was "not financially feasible to pursue this litigation at this time." The court granted the motion and officially terminated the case on 2013-08-26. No settlement between the parties was publicly announced.

The case was dismissed before any significant pre-trial developments, such as a claim construction (Markman) hearing, could take place.

Post-Dismissal FTC Action and PTAB Proceeding

The dismissal of the lawsuit did not end the scrutiny of MPHJ's tactics. In 2014-05-13, the FTC announced a final order settling charges against MPHJ and its law firm for using deceptive and unfair practices in their licensing campaign. The settlement barred them from making false or unsubstantiated infringement claims in the future.

Interestingly, after the district court case was already dismissed, Lexmark filed a petition for inter partes review (IPR) against the '590 patent on 2013-12-20. In case IPR2014-00293, the Patent Trial and Appeal Board (PTAB) ultimately declined to institute the review, finding Lexmark had not shown a reasonable likelihood of prevailing on its invalidity contentions. This PTAB decision, however, had no direct effect on the previously terminated litigation.

I'll search for press coverage of this case from multiple angles.

Let me search specifically for press coverage of the Lexmark case and the '590 patent IPR.

Press and trade coverage

Bottom line: I could not locate any published article — in Reuters, Bloomberg Law, Law360, Ars Technica, The Verge, IPWatchdog, Patently-O, JD Supra, EFF Deeplinks, or the printer trade press — that reports on this specific docket (MPHJ v. Lexmark, No. 3:12-cv-03031, S.D. Cal.). Searching the caption, the party names, and the '590 patent number returns PTAB papers, the Vermont Attorney General litigation, and the Federal Circuit's MPHJ v. Ricoh decision, but no news item describing the filing, Lexmark's February 2013 motion to dismiss, or the August 2013 voluntary dismissal. That absence is itself consistent with the case's short life and with the fact that the press narrative around MPHJ was driven by the demand-letter campaign, the state AG actions, and the IPRs rather than by this docket. Readers should treat the case-specific chronology in the earlier sections as drawn from court records, not from journalism.

The closest thing to press treatment of Lexmark's role is the coverage of the inter partes reviews. Sterne Kessler, announcing the March 2014 joint petitions on the '173 and '410 patents, framed them as "a continuing effort to protect Ricoh, Xerox and Lexmark customers and dealers against the assertion of these patents by MPHJ," and quoted a joint statement from the three companies: "We feel strongly that the infringement claims are without merit and the licensing demands of MPHJ are unsubstantiated. We feel it is important to take this action to support our customers and dealer networks from these frivolous claims." Law360 (May 27, 2015, republished by Industry Analysts) covered the PTAB oral hearing at which the three OEMs called MPHJ's defense "nonsensical," and Law360 (Feb. 13, 2017, by Ryan Davis) reported the Federal Circuit's affirmance invalidating all claims of the '173 patent.

Flagging a contradiction: that February 2017 Law360 piece states that Ricoh, Xerox and Lexmark "were not accused of infringement by MPHJ but supply printers to the companies it has targeted." That is difficult to reconcile with the case metadata here, which records MPHJ suing Lexmark in the Southern District of California in December 2012. The contemporaneous reporting supports Law360's framing rather than the metadata: Ars Technica (Jan. 2014) described Lexmark, Xerox, Ricoh and HP as OEMs "at odds with MPHJ" whose customers were being sued, while Canon and Sharp had cut deals with MPHJ, and Boing Boing (Jan. 7, 2014) put it more bluntly, writing that the troll "relies on the fact that all three companies use Xerox and Lexmark products and since these two companies haven't paid ransom for their customers, it can be assumed that anyone using their devices violates the patents." Neither outlet mentions a Lexmark lawsuit. I have not verified the S.D. Cal. docket directly, so I flag rather than resolve the discrepancy.

Coverage of the underlying campaign supplies the numbers the press did report, none of which relates specifically to Lexmark. Ars Technica (Nov. 2014) reported that MPHJ, working with Farney Daniels, "sent out more than 9,000 patent demand letters ... asking them to pay a royalty of around $1,000 per employee," and characterized the FTC settlement as one with "no monetary penalty," quoting the App Developers Alliance's Jon Potter calling it not "even ... a slap on the wrist." Law360 (Jan. 22, 2014, by Melissa Lipman, reprinted by Mayer Brown) covered the New York AG's "groundbreaking settlement" and quoted outside counsel — Squire Sanders' Mark Botti and Mayer Brown's Christopher Kelly — on whether MPHJ signaled broader antitrust enforcement against patent assertion entities. Campbell Law Observer reported that 16,465 businesses received letters and listed the '590 patent among the five "Klein Patents" MPHJ acquired via Project Paperless.

Two notes on the record versus the commentary. First, the analytical writing on the merits all concerns patents other than the '590 patent at issue here — AEON Law and Lexology (March 2017) both analyze the '173 patent's provisional-application problem, not the '590 patent. Second, I found no reporting at all on the IPR against the '590 patent (identified in the earlier sections as IPR2014-00293, filed Dec. 20, 2013, with institution denied); that proceeding appears only in PTAB filings, and the earlier section's description of the '590 patent as claiming "a method for monitoring the use of a network resource ... for billing purposes" is inconsistent with the complaint language quoted in the same section, which titles it "Virtual Office Management System And Method."
