Express Mobile v. GoDaddy: Federal Circuit Issues Split Ruling on Web Builder Patents
Express Mobile asserted five patents against GoDaddy’s Managed WordPress and Website Builder platforms. After 601 days at the Federal Circuit, the court issued a fragmented ruling — reversing in part, vacating in part, affirming in part, and remanding — leaving the dispute unresolved on multiple fronts.
A Five-Patent Web Builder Dispute Yields No Clean Winner at the Federal Circuit
Express Mobile, Inc. brought an infringement action against GoDaddy.com, Inc. asserting five U.S. patents — US7594168B2, US9063755B2, US6546397B1, US9928044B2, and US9471287B2 — covering web application delivery and browser-based website building technology. The accused products were GoDaddy’s commercially significant Managed WordPress (MWP) and Website Builder (WSB) platforms, two of GoDaddy’s core hosted web-creation offerings.
The Federal Circuit’s April 2, 2025 ruling did not deliver a clean resolution. The court reversed certain aspects of the lower decision, vacated others — nullifying those rulings and directing reconsideration — and affirmed the remainder, before remanding the case. The basis of termination includes dismissal in part, suggesting some claim lines were procedurally closed while others were returned for further adjudication.
The 601-day appellate timeline and fragmented outcome suggest substantial doctrinal complexity across the five asserted patents, possibly involving claim construction disputes, eligibility challenges, or conflicting infringement findings. The remand means neither party achieves finality: Express Mobile retains live claims, while GoDaddy faces continued exposure on the reversed and remanded issues. The precise scope of what was reversed versus vacated versus affirmed is not fully detailed in the public record.

Federal Circuit’s split ruling: what reversed, vacated, and remanded means
Three-way split ruling is rare and consequential
A Federal Circuit ruling that is simultaneously reversed in part, vacated in part, and affirmed in part is uncommon and signals deep disagreement on discrete issues. ‘Reversed’ means the lower court erred and the outcome changes. ‘Vacated’ means the ruling is nullified and the issue returns for reconsideration. ‘Affirmed’ means the lower court was correct. The remand instruction means the district court must act further on the open issues.
Remand requiredExpress Mobile wins on some issues, returns to litigate others
The partial reversal is a meaningful procedural win for Express Mobile — it suggests the Federal Circuit found reversible error in at least one lower court holding that had gone against the plaintiff. However, the partial affirmance means Express Mobile did not prevail across the board. The remand preserves live claims, keeping enforcement prospects open but extending litigation timelines further.
Partial win — case continuesGoDaddy escapes on some claims but faces remanded exposure
The partial affirmance provides GoDaddy with confirmed wins on specific issues, and the dismissal in part closes certain claim lines permanently. However, the reversal and remand mean GoDaddy’s Managed WordPress and Website Builder products remain under active patent risk on the non-affirmed issues. Further district court proceedings will determine ultimate liability and remedies on those issues.
Residual infringement exposureWeb builder platforms face ongoing IP uncertainty post-remand
The remand creates continued uncertainty for operators of browser-based website creation platforms. With five patents spanning web application delivery architecture still partially in play, competitors offering functionally similar hosted web builder products should assess their exposure. The Federal Circuit’s partial reversal suggests at least some of Express Mobile’s patent claims survived challenge — potentially strengthening their enforceability going forward.

Official order — verbatim text
The Federal Circuit’s order — ‘REVERSED IN PART, VACATED IN PART, AFFIRMED IN PART, AND REMANDED’ — reflects distinct appellate dispositions applied to discrete issues across a five-patent record. At the Federal Circuit, reversal requires a finding that the lower court committed legal error; vacatur nullifies without prejudice to reconsideration; and affirmance confirms the lower court applied the correct standard. The concurrent remand instruction directs the district court to conduct further proceedings consistent with the Federal Circuit’s guidance, preserving live issues for both parties.
US7594168B2 and four further web application delivery patents
The five asserted patents — US7594168B2, US9063755B2, US6546397B1, US9928044B2, and US9471287B2 — collectively cover browser-based web application delivery, website builder runtime architectures, and methods for generating and presenting web content dynamically. The portfolio spans application numbers filed across multiple generations, suggesting a prosecution strategy designed to capture evolving implementations of web creation technology from early hosted web applications through modern managed platforms.
This patent portfolio is strategically positioned against the core commercial products of major web hosting providers. GoDaddy’s Managed WordPress and Website Builder are among the most widely deployed hosted web creation platforms globally, making them high-value enforcement targets. The breadth of the five-patent portfolio — covering both early-filed (US6546397B1, application 09/454061) and more recent patents (US9928044B2, application 15/706746) — suggests Express Mobile has pursued continuations designed to capture modern implementations, increasing risk for current-generation platform operators.
Should you run an FTO against Express Mobile’s web builder patent portfolio?
Any company operating a hosted website builder, managed WordPress service, or browser-based web application delivery platform should treat this case as a direct FTO trigger. Express Mobile has demonstrated willingness and capability to pursue Federal Circuit-level enforcement across five patents simultaneously. The partial reversal in this case suggests at least some claims are viable — product teams building or acquiring web creation platforms should assess claim overlap before launch or M&A.

What this case signals for the web builder and hosted platform IP landscape
A five-patent Federal Circuit split ruling rarely ends cleanly — here is what IP teams in the web technology sector need to watch.
Multi-patent assertion strategies at Federal Circuit produce fragmented outcomes
When plaintiffs assert five patents simultaneously, appellate courts frequently reach different conclusions on different patents or claim sets. This case’s three-way split ruling is consistent with that pattern and suggests patent-by-patent claim construction or eligibility analysis drove materially different outcomes across the portfolio.
GoDaddy’s MWP and WSB products remain under patent risk pending remand
The partial reversal and remand mean GoDaddy cannot treat this matter as resolved. Companies operating competing hosted website builder or managed WordPress products should treat the remand proceedings as a live enforcement signal and consider freedom-to-operate analysis against the five Express Mobile patents.
Express v GoDaddy.com — key questions answered
The Federal Circuit issued a split ruling on April 2, 2025: reversed in part, vacated in part, affirmed in part, and remanded. This means some lower court holdings were overturned, others nullified for reconsideration, and others confirmed — with the case returned to district court for further proceedings on the open issues.
Express Mobile asserted five patents: US7594168B2, US9063755B2, US6546397B1, US9928044B2, and US9471287B2. These patents cover web application delivery, browser-based website builder architectures, and web content presentation methods. The accused products were GoDaddy’s Managed WordPress (MWP) and Website Builder (WSB) platforms.
A remand means the Federal Circuit has returned specific issues to the lower court for further proceedings consistent with its guidance. For this case, it means GoDaddy’s Managed WordPress and Website Builder products remain under active patent risk on the non-affirmed issues, and final resolution of liability and remedies has not yet occurred.
The partial reversal suggests the Federal Circuit found reversible error in at least one holding that had previously favored GoDaddy, which typically strengthens the patent holder’s negotiating and enforcement position. However, the partial affirmance confirms GoDaddy prevailed on some issues, so the impact varies by claim and patent. The full picture depends on which specific patents and claims were reversed versus affirmed.
The Federal Circuit’s partial reversal suggests at least some of Express Mobile’s web builder patents survived appellate challenge with viable claims intact. Operators of hosted website creation platforms, managed WordPress services, or browser-based web application delivery systems should consider a freedom-to-operate analysis against the five asserted patents, particularly given Express Mobile’s demonstrated enforcement posture across the portfolio.
