Connectivity with CFE
On October 15, 2007, the CBOE Futures Exchange, LLC (CFE) announced it would provide connectivity to Calyon Financial through Patsystems, enabling Calyon Financial's customers access to all CFE products, including futures on the well-known CBOE Volatility Index (VIX).
Patsystems was founded in 1994 by a group of derivatives traders and technology professionals at a time when the futures markets were beginning to migrate from physical trading floors to an electronic model. Tom Theys, a former CBOT runner, designed the Patsystems software, which he came up with while working at Liffe. He invented a hand-held device that would put orders into other markets and built an interface that would connect the hand-held to DTB (the forerunner to Eurex) to facilitate arbitrage with Liffe. That led to a plan to offer clients direct access to exchanges through the internet; the software Theys designed would then be distributed to locals in dealing rooms or in their homes. Also, Theys and the other Patsystems founders were interested in retail as well as institutional customers. Eventually, the company was approached by Investec, a South African bank that wanted to take Patsystems public. Patsystems was one of the first ISVs to include risk management in its software.
- Acquired Tamesis August 2005. The acquisition gave Pats access to real-time trade capture, valuation and risk management systems for the structured finance and credit derivatives market 
- Fall 2005 Patsystems became the first competitor of Trading Technologies (TT) to acknowledge that its software infringed on TT's patents.

Pats also agreed to pay TT at least 10 cents per transaction for customers using DOME. 
- Maiden dividend declared in 2007
