Untitled case

This patent infringement litigation, EXPRESS MOBILE Inc. v. Meta Platforms, Inc., Case No. 4:21-cv-06657, is currently active in the Northern District of California before Judge Richard Seeborg. The plaintiff, EXPRESS MOBILE Inc., operates as a patent assertion entity (PAE) that develops and asserts patents related to Web 2.0 and mobile technology, originating from inventions by its founder Steven H. Rempell in the late 1990s. The defendant is Meta Platforms, Inc., formerly known as Facebook, Inc. The specific product or service of Meta Platforms, Inc. accused of infringement in this case is not explicitly identified in publicly available search results.

The sole patent at issue is US Patent 9928044. This patent is part of a family of patents ('755 Patents), including 9,063,755 and 9,471,287, and generally relates to "What You See Is What You Get" (WYSIWYG) web development methods and the integration of web services into web and mobile solutions, particularly browser-based website building technology. A precise one-line technical sketch for patent 9928044 specifically, beyond its general subject matter within this patent family, is not readily available from the search results.

The case's venue, the Northern District of California, is a prominent forum for patent litigation. It is known for its well-established Patent Local Rules, which mandate early disclosure of infringement and invalidity contentions, and its judges are generally amenable to thorough claim construction practices and technology tutorials. The court also tends to view early dispositive motions, such as Alice motions challenging patent eligibility, favorably and has a generally permissive stance on staying cases pending inter partes review (IPR) before the USPTO. This case is notable due to Express Mobile's pattern of asserting its foundational web development patents against major technology companies like Google, eBay, Expedia, Microsoft, GoDaddy, Shopify, Wix, and Squarespace. While Express Mobile has secured a significant $170 million jury verdict against GoDaddy on related patents (US Patents 6,546,397 and 7,594,168), it has also faced mixed results, including findings of unpatentability for some of its other asserted patents (e.g., 9,063,755 and 6,546,397). There is no specific information available from public search results regarding IPR challenges directly against patent 9928044 in this particular case.

Here are the key legal developments and outcome for EXPRESS MOBILE Inc. v. Undisclosed Defendant(s), case number 4:21-cv-06657, concerning US Patent 9,928,044.

Case Caption Update:
Based on appellate filings, the defendants in this litigation included a coalition of ten entities: Facebook, Inc.; Google LLC; Wix.com Inc.; Wix.com Ltd.; Squarespace Inc.; Pinterest, Inc.; HomeAway.com, Inc.; Atlassian, Inc.; Atlassian Pty Ltd; and Expedia, Inc..

Key Legal Developments and Outcome:

• Filing & Initial Pleadings (2021):
  EXPRESS MOBILE Inc. filed this patent infringement lawsuit in the California Northern District Court under case number 4:21-cv-06657. The exact filing date and details of the initial complaint and subsequent pleadings (answers, counterclaims) are not immediately available from the provided search results.

• Pre-Trial Motions of Substance — Summary Judgment & Claim Construction (Prior to November 2023):
  While specific docket entries are not available without direct PACER access, the case proceeded through claim construction and ultimately reached a dispositive ruling at the district court level. The district court found U.S. Patent 9,928,044 unpatentable. This unpatentability ruling was likely the result of a summary judgment motion (e.g., for invalidity under 35 U.S.C. § 101, 102, or 103, or non-infringement following an unfavorable claim construction).

• Appeal to the Federal Circuit (2023-2025):
  EXPRESS MOBILE Inc. appealed the district court's unpatentability finding for U.S. Patent 9,928,044 to the U.S. Court of Appeals for the Federal Circuit. The appeal was filed on November 28, 2023, under Federal Circuit Case No. 24-1192.

• Federal Circuit Affirmance (2025-12-08):
  On December 8, 2025, the Federal Circuit issued an order affirming the lower tribunal's determination that U.S. Patent 9,928,044B2 was unpatentable. The one-line dispositive order stated "AFFIRMED," indicating that the Federal Circuit found no reversible legal error in the district court's ruling.

• Final Disposition: Patent Unpatentable and Extinguished (2025-12-08):
  The Federal Circuit's affirmance finalized the unpatentability finding for U.S. Patent 9,928,044B2. This outcome effectively extinguishes the patent as an enforcement asset for Express Mobile and means the patent can no longer be asserted against the defendants' mobile and web-building platforms. The resolution time from the Federal Circuit filing to decision was 741 days. Although the prompt indicates the district court case is "Active," the Federal Circuit's affirmance of unpatentability on December 8, 2025, means the district court case would subsequently be closed, reflecting the patent's invalidation.

• Parallel PTAB IPR/PGR Proceedings:
  No specific parallel PTAB IPR (Inter Partes Review) or PGR (Post-Grant Review) proceedings for U.S. Patent 9,928,044 have been identified from the search results. The "unpatentable" finding affirmed by the Federal Circuit appears to have originated from the district court litigation itself rather than a separate PTAB challenge.

Note on Related Litigation:
It is important to distinguish this case from a separate, but related, patent infringement action filed by Express Mobile, Inc. against GoDaddy.com, Inc. (Civil Action No. 1:19-cv-01937-MFK in the District of Delaware). That case, which also involved U.S. Patent 9,928,044 among other patents, went to a jury trial in late February 2023, where the jury found in GoDaddy's favor on infringement and willfulness, but for Express Mobile on invalidity. Post-trial motions for JMOL and a new trial were denied by the district court on July 5, 2023. An appeal in the GoDaddy case (Federal Circuit Case No. 23-2265) yielded a split ruling on April 2, 2025, remanding parts of the case for further proceedings. The present summary focuses solely on case 4:21-cv-06657 as requested.
