N OPEN LETTER ON THE LEG L RIGHTS OF THE SICBOOST P TENT

Recent discovery and discussion on the pending ASICBOOST patent infringement has attracted widespread attention in the Bitcoin community. Many condemned willful patent infringements committed by some bitcoin chip and miner manufacturers. In fact, the patent inventor claimed its worldwide priority date at the end of 2013. The corresponding PCT application was published in May of 2015 and is entitled to provisional rights in those PCT participating countries including the U.S., China, Europe, and Korea since its publication date. To date, no individual or business entity has been authorized to use or sell products based on the ASICBOOST patent application, yet some bitcoin miner manufacturers have implemented various features of the pending ASICBOOST patent in their mining hardware and firmware potentially infringing the pending ASICBOOST patent. They have not only seriously violated the legal rights of the owner of the pending ASICBOOST patent, but also gained unfair advantage in this business sector. Additionally, the potentially infringing products irresponsibly put innocent consumers at various legal and commercial risks. Therefore, our law firm is authorized by the patent holding company to make this general announcement. All parties related to the potential patent infringement , such as Bitcoin chip makers, Bitcoin miner manufacturers and their sales representatives shall immediately cease production and sales activities of any products in connection to the pending patent application. The infringers should contact our firm and disclose their production and sales records related to our patent pending technology since 2015. Otherwise, we will have no choice but to take legal actions to protect the legal rights of the patent holding company,
