提到區塊鏈專利的申請人,通常會想到的大多是新創公司 (start-up),但美國銀行(Bank of America)顯然不想在未來可能發生的區塊鏈海嘯中被吞噬或被邊緣化,其從2015年11月開始陸續申請了區塊鏈相關的專利,至本文截稿前的公開資料總共有32件專利申請案。一探美國銀行過往的專利申請量,可以發現其在技術研發的智財保護上投入不少資源,自2009年起每年都有超過一百件以上的專利申請,2012到2016年每年的申請量都在四百件上下。
美國銀行申請的區塊鏈專利分布在不同的應用上,礙於篇幅此處僅挑幾件列出作為代表,例如:「使用區塊鏈與智慧合約的透明自我管理獎勵計畫(TRANSPARENT SELF-MANAGING REWARDS PROGRAM USING BLOCKCHAIN AND SMART CONTRACTS)」、「用於人對人付款的區塊鏈別名(BLOCK CHAIN ALIAS FOR PERSON-TO-PERSON PAYMENTS)」、「用於分散式資源狀態的外部確認之系統(SYSTEM FOR EXTERNAL VALIDATION OF DISTRIBUTED RESOURCE STATUS)」、「用於橫越多個網路節點執行分散式賬本的系統(SYSTEM FOR IMPLEMENTING A DISTRIBUTED LEDGER ACROSS MULTIPLE NETWORK NODES)」、「使用區塊鏈應用來轉換大規格電子程序的系統(SYSTEM FOR TRANSFORMING LARGE SCALE ELECTRONIC PROCESSING USING APPLICATION BLOCK CHAIN)」。
以下是前述6件專利的整理表,其被分配到的技術單位(art unit)是2430/2490密碼學與安全(Cryptography and Security)。
