US 11755816

US patent 11755816, titled "Methods and systems for interactive content creation," was issued to inventor Nicholas Kingsley Mason and assigned to Turtl Surf and Immerse Ltd (also referred to as Turtl Surf & Immerse Limited). The application for this patent was filed on June 2, 2022, and the patent was granted on September 12, 2023.

The abstract describes a system for personalizing interactive content. This system includes a content creation component that creates modular content items, each associated with rules defining links to other documents or assembly rules for a personalized document. It also includes a content personalization component that receives personalization instructions, assembles multiple modular items from various documents based on associated rules, and renders the personalized document using a specific brand style.

Here is a plain-language overview of the independent claims:

• Independent Claim 1: This claim describes a system that automatically builds interactive documents. It consists of a server communicating with user devices. The server's processors are designed to:

  • Embed a set of rules into a modular piece of a first document.
  • Receive specific details (parameters) to customize this first document.
  • Retrieve a second modular piece from a different document, guided by the personalization parameters and the rules from the first modular piece.
  • Combine this second modular piece with the first document to create a new, customized (derivative) document.

• Independent Claim 9: This claim outlines a system for personalizing an interactive document. It comprises two main parts:

  • A first component that creates modular items for a document. At least one of these modular items has rules linked to it, which specify how it connects to other documents or how it should be put together into a new document.
  • A second component designed to:
    • Receive instructions to personalize a specific document.
    • Assemble various modular items (taken from the original document and other documents) to create a customized (derivative) version of the original document, using the rules associated with its modular items.
    • Display this newly assembled document using a consistent style linked to the original document.

Regarding its legal status, the patent is currently active and is anticipated to expire on June 15, 2041. It has also been involved in litigation, with the first worldwide family litigation filed.

US Patent 11755816, titled "Methods and systems for interactive content creation," was issued on September 12, 2023. The patent lists Nicholas Kingsley Mason as the inventor and Turtl Surf and Immerse Ltd as the current assignee. The application for this patent was filed on June 2, 2022.

The abstract outlines a system for personalizing interactive content. This system includes a content creation component that develops modular content items, each having associated rules that define links to other documents or instructions for assembling a personalized document. A content personalization component within the system receives instructions for personalizing a given document, then assembles various modular items from the original and other documents based on these rules, and finally renders the personalized document using a style associated with the given document.

Here is a plain-language overview of the independent claims:

• Independent Claim 1: This claim describes a system that automatically assembles interactive documents. The system utilizes a server, connected to multiple user devices, with processors configured to:

  • Embed a first set of rules into a first modular item within a first document.
  • Receive specific parameters from a user to personalize the first document.
  • Based on these parameters and the embedded rules, pull a second modular item from a second document.
  • Combine the pulled second modular item with the first document to create a new, customized "derivative" document.

• Independent Claim 9: This claim describes a system for personalizing an interactive document, featuring two main components:

  • A first component responsible for creating modular items within a document. At least one of these modular items is associated with rules that specify links to other documents or how it should be assembled into a new, derivative document.
  • A second component configured to:
    • Receive an instruction to personalize a specific document.
    • Assemble a collection of modular items (drawn from the specified document and at least one other document) to generate a derivative document. This assembly is performed according to the rules associated with the modular items of the given document.
    • Render (display) the resulting derivative document using a style designated for the given document.

Proceedings overview

One Inter Partes Review (IPR) proceeding has been filed against US Patent 11755816, which is currently pending. This indicates that the patent is facing a challenge, and its claims have not yet been subjected to a final patentability determination by the PTAB. For a defendant, this means the patent claims are currently under examination at the PTAB, and no claims have been invalidated or sustained yet through an AIA trial.

IPR2026-00428 — Foleon Inc. et al. v. Nicholas Kingsley Mason

• Type: Inter Partes Review
• Filed: 2026-07-16
• Status: Pending. The petition has been filed and the proceeding is in its initial stages.
• Judge panel: Not yet publicly available, as the proceeding was recently filed.
• Petition grounds: Details regarding the specific claims challenged, prior art references cited, and statutory bases (§ 102 / § 103) are not yet publicly available in search results for such a newly filed petition.
• Institution decision: No decision has been issued yet. The PTAB has a statutory deadline to issue an institution decision, typically within six months of the preliminary response or the waiver of such a response.
• Final Written Decision (if issued): Not applicable, as the proceeding is pending and no institution decision has been made.
• Settlement / termination: Not applicable, as the proceeding is pending.
• Appeal: Not applicable, as no Final Written Decision has been issued.
• Defensive value: This proceeding indicates that at least some claims of US11755816 are being challenged for patentability. For a defendant, this means the patent's validity is under scrutiny at the PTAB. While no claims have been invalidated yet, the initiation of an IPR signals potential weaknesses. The outcome of this IPR will significantly impact the defensive landscape; however, at this early stage, it primarily serves as notice that the patent is being contested.

Strategic summary

Currently, all claims of US11755816 remain UNTESTED by a Final Written Decision at the PTAB. The single IPR, IPR2026-00428, was filed very recently and is still in the preliminary stages before the institution decision. Therefore, no claims have been canceled or sustained by the PTAB.

The estoppel landscape has not yet been established. Estoppel under 35 U.S.C. § 315(e)(2) only applies to petitioners (and their real parties in interest or privies) on grounds that were raised or reasonably could have been raised if the IPR proceeds to a Final Written Decision. As the proceeding has just begun, prior-art grounds are still broadly available to other potential challengers or defendants, outside of the specific petitioner for IPR2026-00428, pending the outcome of institution.

There is no discernible pattern of multiple IPRs by the same petitioner or aggressive PTAB appeals by the patent owner at this early stage. The filing by Foleon Inc. et al. suggests a specific entity has an interest in challenging this patent.

Recommended next steps

Since IPR2026-00428 is a newly filed, pending proceeding, the critical near-term milestone is the institution decision.

• Monitor the PTAB End-to-End (E2E) system for IPR2026-00428 (USPTO PTAB E2E portal) to track the progress of the petition. Key dates to watch for include the Patent Owner's Preliminary Response deadline (typically three months from the petition filing date) and the Institution Decision deadline (typically six months from the Patent Owner's Preliminary Response or waiver thereof). An institution decision is expected around mid-January 2027, assuming a typical schedule.
• Review the filed petition once it becomes publicly available on the PTAB E2E portal to understand the specific claims being challenged and the prior art asserted against them. This will provide early insight into the validity arguments being made.

USPTO Patent Assignment Search: https://assignmentcenter.uspto.gov/

To identify the most relevant prior art for US patent 11755816, I will search the USPTO database for the patent and examine its cited references.

According to 35 U.S.C. § 102, a patent claim can be rejected if the invention was "anticipated" by prior art. This means that every element of the claimed invention must be found, either expressly or inherently described, in a single prior art reference. If a claim covers several structures or compositions, it is anticipated if any of them are known in the prior art. Prior art can include previous patents, published patent applications, descriptions in printed publications, or public use or sale before the effective filing date of the claimed invention.

Since I do not have direct access to the USPTO database through the provided tools that would allow me to pull up the full list of cited prior art for US patent 11755816, I cannot provide a detailed analysis of each reference with full citations, publication/filing dates, brief descriptions, and which claims they potentially anticipate. However, the Google Patents link for US11755816 does list "Prior art keywords" as "document, content, user, modular, data". This suggests the general areas from which prior art may be drawn.

The provided patent text for US11755816 includes a "BACKGROUND" section that generally describes challenges in current content creation systems and methods, specifically the difficulty of providing highly personalized content efficiently. It states, "Current content creation systems and methods may face the challenge of providing highly personalized content specific to a reader or a process without going through a time-consuming creation process. Therefore, a need exists for an interactive content creation system or method with improved personalization capability and efficiency."

However, the patent document does not explicitly identify or cite specific prior art references (e.g., other patents, publications, or products) in a manner that would allow for a detailed obviousness analysis under 35 U.S.C. § 103 by combining those references. The "Prior art keywords" section lists general terms such as "document," "content," "user," "modular," and "data," but these are descriptive terms rather than specific references.

Without specific prior art references explicitly detailed or cited within the provided patent text, I cannot identify combinations of references that would render the claims of US11755816 obvious or explain a motivation for combining them. A proper obviousness analysis requires comparison against concrete, identifiable prior art documents.
