Research note for BSV TIMES. Public-source review dated 7 September 2026.
The reviewed sources establish commercial patent licensing and public statements about pursuing licences from users of relevant technology. This review did not identify a verifiable patent infringement lawsuit, published patent demand letter identifying an accused party and patent, patent infringement judgment, injunction, or disclosed infringement settlement involving the portfolio under investigation. This is a finding about the sources located, not an exhaustive worldwide docket search or a finding that private demands or negotiations never occurred.
Public statements about obtaining licences and policing use
12 July 2023 — nChain IP chief interviewed by Forbes. Robert Alizon described plans to police competitors operating without paying and said users within and outside BSV should obtain nChain licences. Wright also described a broader plan to enforce IP rights, while the report said his immediate focus was existing litigation and willing licensees. These are attributed statements of intended strategy. The passage does not identify a patent infringement complaint, named defendant, or served patent demand. Forbes interview.
6 February 2024 — official nChain announcement. Alizon described a forthcoming licensing model extending to developers on other blockchains and said participants should obtain licences from nChain. The release identifies no accused implementation, asserted patent claim, infringement proceeding, or enforcement deadline. The obligation asserted in the announcement is the company’s position; it is not a judicial determination that every blockchain implementation infringes. nChain announcement distributed by PR Newswire.
Completed licensing arrangements
| Date | Publicly documented event | What the evidence establishes |
|---|---|---|
| Effective 20 April 2020; announced 24 April 2020 | TAAL entered a ten-year, non-exclusive patent licence, with US$1 million in fees payable during the first year. | A signed commercial agreement and disclosed fee obligation. The announcement does not report a lawsuit or settlement. |
| 2 September 2020 | The TAAL agreement was amended to add transaction-processing patents. | Expansion of an existing licence, as disclosed in TAAL’s annual information form. |
| 30 November 2022 | IPwe announced that ADVASA joined its Blockchain Smart Pool, giving access to more than 1,250 blockchain patents and applications; ADVASA’s CEO specifically identified nChain’s patents. | A named participant’s access through a licensing programme. The announcement does not describe an infringement dispute. |
The TAAL terms and announcement date are supported by nChain’s April 2020 release. The effective date and September amendment are disclosed in TAAL’s annual information form, dated 1 March 2021, printed page 7. The document defines nChain as nChain Licensing AG, and says ownership of the licensed portfolio remained with nChain. It also discloses Stefan Matthews’s roles at both companies. These sources do not establish receipt of the entire fee or infringement by an unrelated company.
The ADVASA event is supported by IPwe’s November 2022 announcement. This is a historical finding; it does not establish the pool’s operational or contractual status in September 2026.
Proceedings that should be classified separately
Patent re-examination. A USPTO notice records a request dated 10 July 2025 to re-examine US12,032,677, case 90/015,375, titled Agent-based Turing complete transactions integrating feedback within a blockchain system. It identifies nChain Licensing AG as owner of record. This is a proceeding concerning the patent’s patentability, not an infringement action brought by nChain. The notice alone does not establish the eventual outcome. USPTO Official Gazette notice, 23 September 2025.
COPA and the identity-related litigation. The 2024 High Court judgment addresses Wright’s claim to be Satoshi Nakamoto and associated claims involving the Bitcoin white paper, software and database rights. It is not a judgment finding infringement of an nChain patent or deciding the validity of the entire later patent portfolio. The claimant’s name, Crypto Open Patent Alliance, does not make the action a patent infringement suit. High Court judgment, 20 May 2024.
US discovery proceeding. The public docket for In the Matter of the Application of nChain Holding AG, 1:24-mi-00068, Northern District of Georgia, was filed on 15 July 2024 under 28 USC §1782 to obtain evidence for UK proceedings. Its listed materials include claims against Christen Ager-Hanssen and others. It was not identified as a patent infringement action. Public docket.
Teranode: a source lead with limited accessible text
Edward Elgar lists a chapter titled Teranode Group in Farnaz Massoumian’s Intellectual Property Strategy: In-House Perspectives, published on 21 April 2026. Search-indexed chapter text describes infringement detection followed by licensing discussions. Full chapter access was unavailable during this review. This lead therefore does not establish a named enforcement target, specific asserted patent, actual demand, or concluded negotiation. Publisher’s chapter listing; indexed chapter page.
Scope and unresolved items
Searches covered nChain and nChain Licensing AG, Wright, Ayre, and Teranode-related names in publicly indexed corporate releases, interviews, court materials and patent records. Generic website licence clauses, statements by unaffiliated commentators, other companies’ blockchain patent cases, and patents containing the technical word “enforcement” were not treated as evidence of action by these entities.
No named patent defendant, published patent-specific demand, damages recovery, injunction, or infringement settlement was verified in this review. Confidential correspondence and licence negotiations remain outside the available evidence. The checked announcements also do not establish that any particular competitor’s implementation falls within a valid patent claim.
