Tabbed-Spreadsheet Claims Found Patent-Eligible

Data Engine Technologies (DET) sued Google claiming that it infringed several claims of U.S. Patents 5,590,259, 5,784,545, 6,282,551 directed to tabbed-spreadsheets, among others. The patents claim system and methods for making complex electronic spreadsheets more accessible by providing familiar, user-friendly interface objects–specifically notebook tabs–to navigate through spreadsheets.

Google asserted that the claims of these patents were directed to abstract ideas and did not provide an inventive concept. The Federal Circuit disagreed finding claims directed to the tabbed spreadsheet were patent eligible in Data Engine Technologies LLC v. Google LLC, No. 2017-1135 (Fed. Cir. 2018).

The court notes that while these tabbed spreadsheet interfaces are common now, “Quattro Pro, the first commercial embodiment of the claimed invention, was highly acclaimed as having revolutionized three-dimensional electronic spreadsheets.” The court goes on to review articles from PC World and Info World touting the advantages of the tabs in improve navigation of three-dimensional sheets.

The Court found that the claims were directed to a specific method for navigating through three-dimensional electronic spreadsheets. And provided a solution to the then-existing technological problems in computers and prior art electronic spreadsheets. The claimed invention solved a known technological problem in a particular way.

Ultimately the court rejected Google’s assertion that the claims were directed to the abstract idea of indexing information because the claims were directed to “an improved user interface for computer devices” and “a particular manner of summarizing and presenting information in electronic devices.”
