In Win For Google, CAFC Holds Patentees May Not Bend Claim Terms to Fit Their Needs

On August 26, the U.S. Court of Appeals for the Federal Circuit (CAFC) affirmed the decision of the United States District Court for the District of Delaware, holding Google LLC did not infringe patents held by Data Engine Technologies LLC (DET). DET sued Google for infringing certain claims of U.S. Patent Nos. 5,590,259; 5,784,545; and 6,282,551 (the Tab Patents). The Tab Patents are directed to systems and methods for displaying and navigating three-dimensional electronic spreadsheets by use of user customizable “notebook tabs” on a spreadsheet interface. The prior art discussed in this trio of patents explained that “three-dimensionality, as presently implemented, is an advanced feature beyond the grasp of many spreadsheet users.” ‘259 patent col. 3 ll. 9-11. Accordingly, the Tab Patents explain, prior art spreadsheets require the user to manipulate each individual spreadsheet within a three-dimensional spreadsheet as an individual window in a graphical window environment. By contrast, the Tab Patents recite notebook tabs that allow the user to simply “flip through” several pages of the notebook to rapidly locate information.

Federal Circuit affirms PTAB Mixed Decision in Acceleration Bay v. Activision Blizzard

Acceleration Bay appealed the final written decisions of the Board holding claims 1-9 of U.S. Patent No. 6,829,634, claims 1-11 and 16-19 of U.S. Patent No. 6,701,344, and claims 1-11 and 16-17 of U.S. Patent No. 6,714,966 all unpatentable. Petitioners Activision Blizzard, Inc., Electronic Arts Inc., Take-Two Interactive Software, Inc., 2k Sports, Inc., and Rockstar Games, Inc. (collectively, “Blizzard”) also cross-appealed portions of the Board’s decisions holding patentable claims 10-18 of the `634 patent, as well as substitute claims 19 of the `966 patent, 21 of the `344 patent, and 25 of the `634 patent. Blizzard also cross appealed the Board’s decisions holding that one particular reference — the Lin article — was not a printed publication under 35 U.S.C. § 102(a). In an opinion authored by Judge Moore and joined by Chief Judge Prost and Judge Reyna, the Federal Circuit affirmed the PTAB decision, finding that both Acceleration Bay’s and Blizzard’s arguments were without merit.

Patent Drafting for Beginners: The anatomy of a patent claim

First, every patent claim needs a preamble, which is the introductory phrase in a claim… Second, every patent claim needs a transition. The most common transitions are: “comprising” and “consisting of” … Third, the first time you introduce a limitation you MUST introduce it with either “a” or “an”, as is grammatically appropriate… Below in an example of an independent claim that applies the above stated three simple rules, which is taken from U.S. Patent No. 6,009,555, titled Multiple component headgear system.

Judge Dyk Suggests En Banc Review of CAFC Preamble Law

I would also like to take issue with Judge Dyk’s statement that it would simply be easier, and better, to say that anything in the preamble is limiting. Yes, that would certainly be easier and probably a better approach than the nebulous standard presently in place, but I doubt that would be to the Supreme Court’s liking given they seem to detest bright line rules, even when they make sense. I also protest such an approach because that has, as far as I can tell, never been the law, or at least not at any time during my practice career. So regardless of whether it is a better test it absolutely should not be applied retroactively to affect those rights obtained under the belief that what is in the preamble is not limiting.
