Nouryon USA LLC v. Aloft Media LLC

I. Executive Summary and Procedural Information

• Parties & Counsel:
  • Plaintiff: Nouryon USA LLC (Delaware)
  • Defendant: Aloft Media, LLC (Texas)
  • Plaintiff's Counsel: Saul Ewing LLP
• Case Identification: 1:26-cv-00193, D. Del., 06/17/2026
• Venue Allegations: Venue is asserted in the District of Delaware on the basis that the Plaintiff is a legal resident of the district and that a substantial part of the events, specifically the Defendant's patent enforcement and licensing efforts directed at the Plaintiff, occurred in the district.
• Core Dispute: Plaintiff seeks a declaratory judgment that its corporate website does not infringe Defendant's patent related to web page hyperlink navigation, and further that the patent is invalid and unenforceable.
• Technical Context: The technology concerns user interface methods for website navigation, specifically the use of multi-level menus that provide users with information about hyperlink destinations before navigating to them.
• Key Procedural History: The complaint alleges an extensive and complex prosecution history for the Asserted Patent. Plaintiff contends that the patent improperly claims priority to a 2006 application, when the subject matter was allegedly first introduced as "new matter" in a 2008 continuation application. This dispute over the correct priority date is central to Plaintiff's invalidity argument, which relies on alleged public use of the invention in July 2006. The complaint also alleges a pattern of inequitable conduct, asserting that the applicants and their attorneys intentionally withheld material prior art from the U.S. Patent and Trademark Office during the prosecution of multiple applications in the patent's family.

Case Timeline

II. Technology and Patent(s)-in-Suit Analysis

• Patent Identification: U.S. Patent No. 10,372,793, "Hyperlink with Graphical Cue," issued August 6, 2019 (the "'793 Patent").

• The Invention Explained:

  • Problem Addressed: The patent's background section identifies a drawback with conventional textual hyperlinks on web pages: the text may not clearly indicate the hyperlink's destination, forcing a user to perform the "tedious and time-consuming" act of navigating to the linked page just to identify its content '793 Patent, col. 1:49-65
  • The Patented Solution: The invention describes a multi-level menu system to improve hyperlink utility '793 Patent, col. 1:24-26 As described, a user's first input on a primary menu item (e.g., hovering over a category) causes the display of a secondary menu of hyperlinks '793 Patent, abstract A key aspect highlighted in the specification involves displaying content from the selected hyperlink's destination simultaneously with the menu, such as within a separate frame on the same web page, allowing the user to preview the destination before committing to navigation '793 Patent, Fig. 5A '793 Patent, col. 3:1-15
  • Technical Importance: This approach aims to make web navigation more efficient by giving users a "graphical cue" or preview of a link's content, reducing unnecessary page loads and improving the user experience on content-rich websites '793 Patent, col. 2:7-15

• Key Claims at a Glance:

  • The complaint identifies independent claim 23 as the asserted claim Compl. ¶48
  • The essential elements of Claim 23 are:
    • Providing content for a web page with a set of menu items and initially hidden hyperlinks.
    • The menu items are displayed without images, and the hyperlinks take the form of hypertext.
    • Allowing a first input (hovering) to select a menu item.
    • In response, displaying the set of hyperlinks.
    • Allowing a second input to select a hyperlink.
    • In response, displaying a destination that includes "at least a portion of additional content displayed simultaneously with the set of one or more representations of one or more menu items." Compl. ¶48
  • The complaint does not mention other asserted claims but seeks a declaration of non-infringement as to all claims Prayer ¶A

III. The Accused Instrumentality

• Product Identification: The accused instrumentality is Plaintiff Nouryon's corporate website, located at https://www.nouryon.com/ (the "Accused Nouryon Website") Compl. ¶27

• Functionality and Market Context:

  • The complaint describes the Accused Nouryon Website as a tool to engage with the public and market its chemical services and solutions Compl. ¶27
  • Its navigation relies on a nested menu system where a user first selects a top-level menu option (e.g., "Markets"), which reveals sub-options (e.g., "Crop Nutrition") Compl. ¶51
  • The complaint alleges that selecting a sub-option navigates the user to an entirely new, server-rendered web page Compl. ¶52 It asserts that the website does not use technologies like AJAX, client-side rendering, or frames to display a preview of the destination page before the user navigates away from the current page Compl. ¶53 Compl. ¶68 A screenshot provided in the complaint shows a standard drop-down menu where hovering over "Markets" reveals a list of text-based sub-category links Compl. ¶67, p. 15

IV. Analysis of Infringement Allegations

The complaint is for a declaratory judgment of non-infringement. The following table summarizes Nouryon's description of its website's functionality as it maps to the elements of the asserted claim, forming the basis for its non-infringement argument.

'793 Patent Infringement Allegations

• Identified Points of Contention:
  • Technical Question: A central dispute concerns the final "cause...display" step. The complaint argues the accused website does not meet this limitation because it navigates the user to a completely new page, rather than displaying a preview of the destination content on the original page simultaneously with the original menu Compl. ¶61 Compl. ¶68 The complaint uses Figure 5A of the patent, which depicts content displayed in a separate frame (502b) on the same page as the menu (502a), to support its interpretation that a non-navigational preview is required Compl. ¶64 Compl. ¶65 This raises the question of whether navigating to a new page that re-renders the menu alongside new content satisfies the "simultaneously displayed" requirement.
  • Scope Questions: The complaint raises a claim scope question regarding the term "destination." It alleges that the patent specification describes "destination" as an external website, whereas the accused website's menus only link to internal pages within the same site Compl. ¶60 The court may need to determine if the claims are limited to external destinations.

V. Key Claim Terms for Construction

• The Term: "display of a destination... displayed simultaneously with the set of one or more representations of one or more menu items"

• Context and Importance: The interpretation of this phrase is central to the non-infringement argument. Practitioners may focus on this term because if it is construed to require the display of destination content on the same page as the initial menu (e.g., in a frame or via AJAX) without full navigation, then the accused website, which performs a full page load, would likely not infringe Compl. ¶61

• Intrinsic Evidence for Interpretation:

  • Evidence for a Broader Interpretation: A party could argue that the plain language does not explicitly forbid a page reload. If the destination page contains the required "additional content" and also displays "an instance" of the menu, it could be argued that they are "simultaneously displayed" on the user's screen at that moment.
  • Evidence for a Narrower Interpretation: The complaint points to the patent's background, which criticizes the "tedious and time-consuming" process of navigating away from the current page to identify a link's destination '793 Patent, col. 1:56-65 Compl. ¶61 Figure 5A, which shows a menu in a first frame (502a) and the destination preview in a second frame (502b) on a single web page (500), strongly suggests the invention's purpose is to provide a preview without full navigation Compl. ¶64 Compl. ¶65 This context may support a narrower construction requiring the display to occur on the initial page.

VI. Other Allegations

• Indirect Infringement: The complaint preemptively seeks a declaration that Nouryon is not liable for any induced, contributory, or other indirect infringement, but it does not detail any specific allegations of such conduct made by Aloft Media Compl. ¶58

• Inequitable Conduct and Prosecution Laches: The complaint includes extensive allegations that the '793 patent is unenforceable.

  • Inequitable Conduct: The allegations are twofold. First, the complaint alleges that throughout the patent's prosecution chain, the applicants and their attorneys failed to disclose to the USPTO numerous material prior art references that they were aware of from co-pending and related prosecutions Compl. ¶¶114-119 Compl. ¶¶128-130 Second, it alleges that the applicants made materially false statements to the USPTO by repeatedly certifying that a 2008 application ('068) and its descendants contained "no new matter" relative to a 2006 parent application ('957), when in fact the 2008 application allegedly introduced the core inventive concept. This was allegedly done with deceptive intent to gain an earlier priority date and avoid intervening prior art Compl. ¶¶160-163 Compl. ¶194
  • Prosecution Laches: The complaint alleges that there was an unreasonable and unexplained delay in the prosecution of the patent, which spans a chain of applications from 2006 to 2019, and that this delay has prejudiced Nouryon and the public Compl. ¶¶203-205

VII. Analyst's Conclusion: Key Questions for the Case

1. A question of definitional scope: How will the court construe the phrase "displayed simultaneously with the... menu items"? The case may turn on whether this requires a preview of destination content on the initial web page, as suggested by the patent's specification and figures, or if it can be read more broadly to cover navigating to a new page where the menu is simply reloaded alongside new content.

2. A question of patent validity: Is the '793 patent entitled to its claimed 2006 priority date? This will involve a fact-intensive analysis of whether the 2008 application in its prosecution chain introduced impermissible "new matter," which would render the patent's effective filing date much later and potentially invalidate it in light of alleged prior art from mid-2006.

3. A question of patent enforceability: Did the applicants and their counsel engage in inequitable conduct? The court will have to weigh extensive evidence regarding whether they intentionally withheld material prior art and knowingly made false statements to the USPTO regarding new matter with an intent to deceive.
