In Data Engine Technologies LLC v. Google LLC, [2017-1135] (October 9, 2018), the Federal Circuit affirmed in part, reversed in part, and remanded, entry of judgment on the pleadings holding that the asserted claims of DET’s U.S. Patent Nos. 5,590,259; 5,784,545; 6,282,551; and 5,303,146 are ineligible under 35 U.S.C. § 101.

The Federal Circuit concluded that with the exception of claim 1 of the ’551 patent, the asserted claims of the ’259, ’545, and ’551 patents are directed to patent-eligible subject matter, finding that these claims claims are not abstract, but rather are directed to a
specific improved method for navigating through complex three-dimensional electronic spreadsheets. The Federal Circuit agreed that the asserted claims of the ’146 patent,
reciting methods for tracking changes to data in spreadsheets, were directed to the abstract idea of collecting, recognizing, and storing changed information.

Regarding the ’259, ’545, and ’551 patents, the Federal Circuit said that the claimed method does not recite the idea of navigating through spreadsheet pages using buttons or a generic method of labeling and organizing spreadsheets. Rather, the claims require a specific interface and implementation for navigating complex three-dimensional spreadsheets using techniques unique to computers.
