Trading Techs. Int’l, Inc. v. eSpeed, Inc., No. 04C 5312, Slip Op. (N.D. Ill. Sep. 25, 2007) (Moran, Sen. J.). 

Judge Moran denied plaintiff Trading Technologies’ (“TT”) supplemental summary judgment motion. The Court previously denied the original motions regarding the priority dates of the patents in suit.* In that opinion, the Court held that whether the patents could claim priority from their provisional application was a question of fact for the jury. The issue was whether disclosing the species of a single mouse click in the provisional application was sufficient support for the genus – a single action by the user – claimed in the patents in suit.

TT argued that eSpeed’s expert’s statement that the art – software engineering and user interface design – was predictable, was sufficient to take the patents out of the In re Curtis, 354 F.3d 1347 (Fed. Cir. 2004), exception (unpredictability of a species prevents support of a genus). The Court agreed that the factual issue was predictability of the art. But the Court held that eSpeed’s expert’s statement did not resolve the dispute. A generally predictable art does not mean that one of ordinary skill would understand the patentee’s description of the particular species (one-click) was necessarily in possession of the genus (one action). So the issue went to the jury.

As of this post, the jury still has this case.  I will let you know as soon as I learn the jury’s verdict.  For more on this case and Trading Technologies’ related cases click here for the Blog’s archives.  And keep watching the Blog, while the jury deliberates and the parties try inequitable conduct to Judge Moran this week, I will continue catching up with some prior opinions from the case.
