Safe IP, LLC v. Proctorio, Inc. — Patent Infringement, Case Terminated
Safe IP, LLC asserted US9043375B2 — covering plagiarism detection system technology — against Proctorio, Inc. in the District of Delaware. The case was terminated after a stay order issued in November 2022, with the docket formally closed in November 2025, spanning over 1,200 days.
Plagiarism detection patent action stayed early, then quietly closed
Safe IP, LLC filed Case No. 1:22-cv-00920 in the District of Delaware on July 11, 2022, asserting US9043375B2 — a patent directed to plagiarism detection system technology — against Proctorio, Inc., a provider of remote proctoring and academic integrity software. The action was one of three related cases filed on the same date by the same plaintiff, also identified as 1:22-cv-00918-CFC and 1:22-cv-00919-CFC, suggesting a coordinated enforcement campaign.
Proceedings moved quickly toward an early halt: on November 22, 2022, the court entered an order staying all three associated cases, and an evidentiary hearing scheduled for November 30, 2022 was terminated in connection with that stay. The docket was formally closed on November 20, 2025, more than three years after filing. The basis of termination is recorded simply as ‘Case Terminated,’ leaving the precise legal mechanism — whether settlement, voluntary dismissal, or other resolution — ambiguous from the public record.
The early stay, issued within just over four months of filing, is consistent with either a parallel IPR or inter partes review proceeding, a parallel district court coordination, or a negotiated resolution that preceded full merits adjudication. The three-year gap between the stay and formal closure is notable and may reflect administrative closure pending a related proceeding. What drove the final termination and whether any licensing arrangement was reached remains unknown from publicly available information.

Case terminated: what the stay order and closure mean for both parties
Stay order terminated proceedings before merits adjudication
The court issued a stay order on November 22, 2022, halting the case before substantive litigation on the merits. A stay suspends — rather than ends — active proceedings, typically pending a related proceeding such as an IPR at the USPTO or parallel litigation. The docket’s formal ‘Case Terminated’ closure in November 2025 suggests the stay was never lifted and the matter resolved or expired without a merits ruling.
Stay → termination, no merits rulingNo infringement finding recorded for Safe IP
Safe IP, LLC obtained no recorded judgment of infringement or damages. The ‘Case Terminated’ basis does not confirm whether Safe IP voluntarily withdrew its claims or whether termination was court-ordered. Without a merits ruling, Safe IP did not publicly establish infringement of US9043375B2 by Proctorio. Whether any private licensing arrangement accompanied closure is not ascertainable from the public docket.
No merits win recordedProctorio faces no injunction or damages award on the record
Proctorio, Inc. was not found liable for infringement on the public record. The early stay meant Proctorio avoided prolonged discovery and trial exposure. However, because no invalidity or non-infringement determination was entered, US9043375B2 remains a potential risk unless it has since expired, been invalidated in a separate proceeding, or been licensed. Proctorio’s freedom to operate with respect to this patent is not formally confirmed by this outcome.
No liability finding; FTO unconfirmedAcademic integrity tech sector faces unresolved plagiarism detection IP
The termination without a merits ruling leaves US9043375B2’s enforceability legally unresolved in this proceeding. Competitors and new entrants in the plagiarism detection and remote proctoring market should note that the patent was asserted in a coordinated three-case campaign, suggesting deliberate enforcement strategy. Absent a confirmed invalidity ruling, the patent may remain a viable assertion risk for the sector until its expiry or USPTO challenge.

Official order — verbatim text
The termination entry reflects an administrative closure following a stay order rather than a merits adjudication. The phrasing ‘Case Terminated per Order Staying Case’ confirms no trial, no summary judgment, and no infringement or validity ruling was issued. For both parties, the absence of a merits disposition means the legal status of US9043375B2 as applied to Proctorio’s products is formally unresolved. The underlying stay order and its basis — not specified in the public docket — are the critical documents for understanding what actually drove resolution.
US9043375B2 — Plagiarism Detection System Technology
US9043375B2 (Application No. US12/253249) is directed to plagiarism detection system technology. The application number prefix suggests filing in the mid-to-late 2000s timeframe, placing its technical disclosure within an era of early automated content-matching and digital academic integrity tools. The patent covers system-level methods for identifying copied or substantially similar content, a foundational function in modern proctoring and LMS-integrated integrity platforms.
The strategic significance of this patent lies in its potential breadth across the academic integrity software market, which has expanded substantially with the shift to online education. Proctorio and comparable platforms — including those offering similarity scoring, source-matching, or document fingerprinting — could fall within its claims if not designed around or invalidated. Safe IP’s coordinated three-case enforcement campaign suggests the patent holder views it as broadly applicable across multiple market participants, raising the stakes for any company operating in this segment.
Should your team run an FTO against US9043375B2?
Any R&D team or product manager developing plagiarism detection, content-similarity scoring, or academic integrity verification features should consider a freedom-to-operate analysis against US9043375B2. The patent was actively asserted in 2022 against a leading proctoring platform, and no invalidity determination has been entered on the public record. EdTech companies, LMS vendors, and AI-powered writing tools with similarity detection functionality are all potentially within scope.

What this case signals for the academic integrity software IP landscape
A coordinated three-case filing and early stay suggest calculated enforcement tactics worth monitoring across the edtech and proctoring sector.
Coordinated multi-case filings signal structured assertion strategy
Safe IP filed three related cases on the same date in Delaware targeting the same technology area. This pattern is consistent with assertion-entity enforcement campaigns designed to maximise settlement pressure. Companies in the plagiarism detection and remote proctoring space should monitor for further filings asserting US9043375B2 or related family members.
Early stay is a signal — check for parallel USPTO proceedings
A stay issued just four months after filing typically suggests a co-pending IPR or ex parte reexamination. Practitioners advising proctoring or edtech clients should verify whether any USPTO challenge to US9043375B2 was filed around Q3–Q4 2022 and what its outcome was, as that proceeding may determine the patent’s residual enforceability.
Safe v Proctorio — key questions answered
The case was terminated without a merits ruling. A stay order was entered on November 22, 2022, halting proceedings approximately four months after filing. The docket was formally closed on November 20, 2025. No infringement finding, damages award, or invalidity determination was entered on the public record.
Safe IP, LLC asserted US9043375B2 (Application No. US12/253249), a patent directed to plagiarism detection system technology. The patent was asserted in connection with Proctorio’s remote proctoring and academic integrity software products.
The public docket records the stay order entered November 22, 2022 but does not specify the precise basis. In Delaware patent cases, stays at this early stage are frequently associated with co-pending IPR proceedings at the USPTO or coordination across related district court cases. The three associated case numbers suggest coordinated multi-case management may have been a factor.
The termination in this case does not confirm or deny the patent’s enforceability. No invalidity ruling was entered. Whether the patent has expired, been challenged in a separate USPTO proceeding, or remains in force requires a dedicated patent status search. Companies in the plagiarism detection space should verify current status before drawing any conclusions.
Safe IP, LLC filed two additional related cases on the same date in the District of Delaware: 1:22-cv-00918-CFC and 1:22-cv-00919-CFC. All three were stayed together per the November 22, 2022 order. This coordinated filing pattern is consistent with a structured patent assertion campaign targeting multiple parties in the same technology sector.
