Heading: The ’411, ’768, and ’374 Continuations

Text: With the applications for the ’411, ’768, and ’374 patents—three parallel continuations that relied on the original written description of the ’132 patent—TT sought claims that removed the term “static” from references to the price column. For example, following the district court’s adverse claim construction determinations in the 10 TRADING TECHNOLOGIES INTL v. OPEN E CRY, LLC eSpeed litigation,3 TT amended the application for the ’411 patent. Up to that time, the application had claimed methods requiring “statically” displayed market price information, similar to the claims of the related ’132 and ’304 patents at issue in eSpeed. But TT’s amendment cancelled every pending claim and introduced new claims that lacked the term “static” in any form, and that term remained absent from the claims issued in the ’411 patent. In addition, TT made comparable amendments to the co-pending applications that gave rise to the ’768 and ’374 patents. Therefore, while the written descriptions of the ’411, ’768, and ’374 patents match those of the earlier ’132 and ’304 patents, the claims differ between the two groups in at least one key respect—unlike the ’132 and ’304 patents at issue in eSpeed, the ’411, ’768, and ’374 patents claim trading methods and software without limitation to a “static” price column display.
