Dr. Craig Wright has filed an Amended Defence in COPA\u2019s lawsuit against him concerning his copyright ownership over the Bitcoin whitepaper, appearing ready and able to answer the suit before the English High Court. COPA began the proceedings in April after Dr. Wright sent copyright infringement notices to certain parties who were illegitimately hosting the whitepaper. At the time, COPA brought the action only on its own behalf. COPA are seeking the court to declare that Dr. Wright does not have copyright ownership rights over the document as its author. Dr. Wright first filed his defense in May. However, in June COPA informed Dr. Wright that it intended to alter its standing in the action so that it was acting not only on its own behalf, but also as representative, and on behalf, of four of its 33 members (Square, Coinbase, Kraken and MicroStrategy). Having obtained Dr. Wright\u2019s consent\u2014and subsequently the Court\u2019s permission\u2014for its proposal, COPA served its Amended Particulars of Claim on September 15. Dr. Wright has since served his consequentially Amended Defence. The Alliance is only the latest of Dr. Wright\u2019s critics to claim to embrace a legal battle with him; for Wright\u2019s part, he been consistent that he\u2019s only interested in responding to challenges against him if it\u2019s in a court. When it comes time for the challengers to walk the walk, however, they seem to disappear. Will COPA be different? In terms of content, there isn\u2019t much in the Defence that will be surprising. Much of it is concerned with contradicting or correcting the narrative spun in COPA\u2019s Particulars of Claim, which is small work considering many of COPA\u2019s assertions are made without basis, while Dr. Wright\u2019s answers are simply those he has given many times before. For example, COPA\u2019s claim repeats the falsehood that Dr. Wright has failed to cryptographically prove his identity as Satoshi Nakamoto; Dr. Wright has consistently maintained that it isn\u2019t possible, and that the possession of private keys does not prove identity. Dr. Wright also asserts when and where the whitepaper was first released\u2014to The Cryptography Mailing List on October 31, 2008, and the Bitcoin code releasing on SourceForge shortly after, on January 9, 2009. The defense makes clear that the code was initially distributed under the MIT license, but the whitepaper itself was not, contrary to the assumption made in COPA\u2019s suit. There are also smaller technical errors in COPA\u2019s version of events, such as the incorrect description of the creation of the genesis block as \u201cmining,\u201d which Dr. Wright\u2019s response meticulously picks apart. The Defence also points out the obvious, uncomfortable reality for COPA, which is that Dr. Wright has already succeeded in the only one of his white paper cases to make it to a courtroom to date. COPA now has until October 11 to serve their Amended Reply to Dr. Wright\u2019s Amended Defence. Though it might not seem like it owing to the fact that COPA is the plaintiff, the ball is in their court at this point. Dr. Wright has successfully pursued a claim over the white paper in the same court in which COPA now seeks to sue him, and everything about this defense suggests that Dr. Wright is steadfast in his willingness to prove his claim to the Satoshi name in court.
