Realtime Data LLC is an inventor-owned research and development company focusing on data compression and acceleration technologies since 1998. Their technology aims to accelerate data storage, retrieval, transmission, and reception, addressing the demand for increased bandwidth, capacity, and speed in modern systems. Realtime Data's patent portfolio includes over 50 US patents and has been licensed to companies in global computing, wireless, streaming media, WAN acceleration, and financial services. Realtime Data LLC has been identified as a "prolific patent assertion entity" by PatSnap, involved in numerous infringement actions across various courts, asserting data compression patent families. These campaigns target data compression products, particularly backup, storage, and data management software, indicating a systematic licensing pressure rather than competition. Litigation records show Realtime Data LLC has asserted this patent, US7415530B2, in multiple infringement cases. For example, it was asserted against Acronis in 2017 and Fortinet (and other co-defendants) in a 2023 Supreme Court petition.
