商务部新闻发言人就美制裁中国企业答记者问亿联网络获专利，SPI传输通过包头提示还有多少数据待发
11月6日，亿联网络（300628）的发明专利《一种基于SPI通信的数据传输方法、系统、介质及终端》获授权，申请号为CN202510093931.9。
两台终端经SPI接口交换信息时，接收侧需要知道后续还要为多少数据留出空间。方案在数据包的头部携带剩余待传输长度，双方据此控制每轮实际传送量。如果仍有后续数据，便更新包头并进入下一轮。若不再有剩余，则终止迭代。技术焦点是把传输长度的协调放到每个数据包中，以减少接收缓冲区溢出的风险。
截至此次授权消息披露时，亿联网络今年获得的各类专利授权共30项，比上年同期减少38.78%。在2026年上半年，公司研发投入为2.31亿元，同比增长7.82%。企业知识产权记录中，厦门亿联网络技术股份有限公司名下可查到900条专利信息和159条著作权信息。
