I'll research TradeStation to verify its profile.
Let me verify the ownership timeline and the litigation context.
TradeStation Technologies, Inc. (formerly Omega Research, Inc., founded 1982) is the technology and intellectual-property subsidiary of TradeStation Group, Inc., headquartered in Plantation, Florida, with additional offices in Richardson, Texas. TradeStation Group was Nasdaq-listed (TRAD) until June 2011, when Monex Group, Inc. (Tokyo Stock Exchange: 8698) acquired it for roughly $402 million and delisted it. TradeStation Technologies is therefore a subsidiary of a Japanese public parent. Entity-level headcount and revenue are not disclosed; third-party estimates for the TradeStation group range widely (roughly 500–1,400 employees; ~$100M–$400M revenue) and are unverified.
Products / services. TradeStation Technologies develops and licenses strategy-trading software and subscription tools and owns the group's intellectual property. The wider group operates the multi-asset TradeStation electronic trading platform for equities, options, futures and forex, offering order execution, market scanning, strategy back-testing and automation via its EasyLanguage language. Brokerage/execution sits in TradeStation Securities, Inc. (a self-clearing broker-dealer and futures commission merchant), TradeStation Forex, Inc. and TradeStation Prime Services, Inc.; portfolio-testing software Portfolio Maestro was acquired from RINA Technologies in 2010. TradeStation 9.5 is a named platform version.
Patent-litigation posture. This is an operating company, overwhelmingly on the defensive side of NPE suits. Of four tracked matters, one is a defense: Chart Trading Development, LLC v. TradeStation Group, Inc. et al., filed December 3, 2015 in the plaintiff-friendly Eastern District of Texas, Tyler Division. The other three are PTAB covered-business-method petitions in which TradeStation appears as a co-petitioner alongside other brokers, not as a standalone filer.
Notable cases/context. CTD — described in filings as a non-practicing entity — asserted trading-interface patents (the '611, '190, '416, '626 and '435 patents) against roughly 32 defendants, accusing the TradeStation 9.5 platform. TradeStation joined CQG and Interactive Brokers in 2016 CBM petitions; the district court stayed the Texas case pending CBM review. Defendants argued CTD was created to insulate its corporate owner, the BGC Group, from discovery.
