1 2 3 4 5 6 7 8 UNITED STATES DISTRICT COURT 9 SOUTHERN DISTRICT OF CALIFORNIA 10 11 VLAD ZAMFIR, Case No.: 21-CV-474 TWR (AHG)

12 Plaintiff, ORDER GRANTING IN PART AND 13 v. DENYING IN PART DEFENDANT’S MOTION TO DISMISS 14 CASPERLABS, LLC,

15 Defendant. (ECF No. 64) 16 17 Presently before the Court is Defendant CasperLabs, LLC’s Motion to Dismiss 18 Plaintiff Vlad Zamfir’s Second Amended Complaint (“Motion,” ECF No. 64), as well as 19 Plaintiff’s Opposition to the Motion (“Opp’n,” ECF No. 65) and Defendant’s Reply in 20 support of the Motion (“Reply,” ECF No. 66). The Court heard oral argument on 21 August 18, 2022. (See ECF No. 69.) Having carefully reviewed Plaintiff’s Second 22 Amended Complaint (“SAC,” ECF No. 56), the Parties’ arguments, and the law, the Court 23 GRANTS IN PART AND DENIES IN PART Defendant’s Motion. 24 BACKGROUND 25 Zamfir is a researcher in blockchain technology and adopted the name “Casper” for 26 his correct-by-construction (“CBC”) proof-of-stake (“PoS”) blockchain consensus 27 protocol. (See SAC ¶ 1.) Zamfir brings this action in response to CasperLabs’ activities, 28 beginning on or about August 2020, where they used the name “Casper” to describe their 1 PoS protocol and filed to register the CASPER mark. (See id.) Zamfir alleges eight causes 2 of action: (1) False Designation of Origin in violation of Section 43(a)(1)(A) of the Lanham 3 Act, 15 U.S.C. § 1125(a)(1)(A) (“Count 1”); (2) Unfair competition/Trademark 4 Infringement in violation of Section 43(a)(1)(A) of the Lanham Act, 15 U.S.C. 5 § 1125(a)(1)(A) (“Count 2”); (3) Trademark Infringement under California Common Law 6 (“Count 3”); (4) Unfair Competition under California Common Law (“Count 4”); 7 (5) Cancellation of U.S. Trademark Registration No. 6202402 (“Count 5”); 8 (6) Cancellation of U.S. Trademark Registration No. 6131157 (“Count 6”); (7) Fraud by 9 Intentional Misrepresentation under California Civil Code §§ 1709, 1710 (“Count 7”); and 10 (8) Unlawful and Unfair Business Practices and False Advertising under California 11 Business & Professions Code § 17200 (“Count 8”). (See generally SAC.) 12 At its core, a blockchain is a distributed protocol that stores transactional records as 13 a chain of “blocks.” (See id. ¶ 12.) Each block contains a cryptographic fingerprint, called 14 a hash, of the previous block; a timestamp; and other data. (See id.) Certain types of 15 blockchain applications, such as those used for cryptocurrency exchanges, rely on 16 consensus protocols to validate the operation of the transaction. (See id. ¶ 14.) Historically, 17 these blockchain-based cryptocurrencies have relied on a “proof of work” (“PoW”) 18 consensus mechanism to secure the network. (See id.) PoW requires a tremendous amount 19 of computational and electrical energy, resulting in issues with the sustainability and 20 workability of this consensus mechanism. (See id.) Therefore, much of the technical 21 development in the blockchain industry has been devoted to the development of an 22 alternative consensus mechanism, namely, PoS. (See id. ¶ 15.) PoS aims to eliminate the 23 computational waste inherent in PoW by using digital resources as opposed to 24 computational resources to create barriers to an attack on the blockchain network. (See id.) 25 In 2014, Zamfir began researching and developing a new PoS blockchain protocol 26 design in conjunction with Vitalik Buterin and the Ethereum Foundation. (See id. ¶ 18.) 27 Zamfir and Buterin took their research in two separate directions. (See id. ¶ 20.) Buterin’s 28 branch of research is now marketed under the name “Ethereum 2.0.” (See id.) Zamfir’s 1 branch of research was called “CBC Casper,” which refers to CBC software design 2 methodology, currently known and referred to throughout the industry as “Casper.” (See 3 id.) 4 Zamfir has been continuously conducting research and development under the 5 Casper name in the United States and internationally since at least March 2015. (See id. 6 ¶ 21.) Zamfir uses the CBC Casper and Casper names exclusively when communicating 7 his work on PoS and distributed systems to the wider public via Twitter, Github, and his 8 personal blogs. (See id. ¶ 22.) By 2017, Zamfir used the Casper mark in commerce in 9 connection with distributing downloadable Casper CBC software and specifications under 10 open-source licensing agreements in the United States. (See id. ¶ 26.) 11 Zamfir has substantially benefitted from the creation and distribution of the CBC 12 Casper software, specification, and protocol under open-source licenses throughout the 13 United States, including generating market shares, promoting international recognition, 14 and obtaining free improvements to CBC Casper. (See id. ¶ 30.) Since 2015, Zamfir has 15 used the Casper trademark in the United States when providing blockchain technology 16 consulting services and marketing his CBC Casper development and consulting services at 17 seminars, conferences, workshops, and lectures on blockchain research in the United 18 States.1 (See id. ¶¶ 29, 30 ̶ 31.) Zamfir received compensation for several of his 19 presentations on Casper, and Zamfir’s research on PoS protocols has received significant 20 coverage in various media outlets. (See id. ¶ 35.) 21 / / / 22

23 1 By March 2017, Zamfir published the first formal verification of CBC Casper on GitHub, which was and remains downloadable by anyone in the United States at https://github.com/pirapira/cbc_casper 24 and https://github.com/vladzamfir/cbc_casper. (See SAC ¶ 27.) By November 2017, Zamfir and the 25 Ethereum research group released a software prototype of Casper on GitHub, which was and remains downloadable by anyone in the United States at https://github.com/ethereum/cbccasper/releases. (See 26 SAC ¶ 28.) On December 18, 2017, Zamfir uploaded to GitHub a draft CBC Casper protocol specification titled “Casper the Friendly Ghost A ‘Correct-by-Construction’ Blockchain Consensus Protocol.” (See 27 SAC ¶ 29.) The paper notes that “[e]arly prototypes of both Casper the Friendly Binary Consensus and Casper the Friendly Ghost have been implemented,” and cites to the source code available for download 28 1 In 2018, CasperLabs asked Zamfir to collaborate on developing a new blockchain. 2 (See id. ¶ 37.) In exchange for Zamfir’s contribution, CasperLabs made Zamfir (1) the lead 3 consensus protocol architect, and (2) the governance committee liaison to outside investors 4 to present the protocol. (See id. ¶¶ 38, 40.) 5 On February 14, 2019, on behalf of himself and his company, Coordination 6 Technology, Ltd. (“CoorTech”), Zamfir entered into a Research Agreement with 7 CasperLabs, under which he would provide research, analysis, and advice to integrate CBC 8 Casper into CasperLabs’ proposed blockchain. (See id. ¶ 39.) On the same day, on behalf 9 of CoorTech, Zamfir entered into a Licensing Agreement with CasperLabs, granting 10 CasperLabs limited rights in the use of his name and image to promote the collaboration in 11 exchange for CasperLabs helping to fund Zamfir’s work on CBC Casper. (See id. ¶ 40.) 12 Within a few months, Zamfir believed that CasperLabs was doing too little to 13 support his research. (See id. ¶ 41.) Zamfir grew concerned that CasperLabs was 14 misappropriating his name and taking advantage of his reputation to mislead investors. 15 (See id. ¶ 42.) Zamfir sent notice to CasperLabs that he intended to terminate both the 16 Research and License Agreements on September 11, 2019. (See id. ¶ 44.) Zamfir 17 subsequently terminated his License Agreement in October 2019, and the Research 18 Agreement on November 2, 2019.
