Secure Axcess, LLC. v. Nintendo of America Inc.
United States District Court for the Western District of Washington
Filed July 7, 2014; Decided August 4, 2015
Case No. 2:14-cv-01013

Secure Axcess filed suit against Nintendo of America S/A alleging infringement of U.S. Patent 6,522,309.  The accused products are Defendants’ Nintendo DS handheld game consoles. 

The ‘309 patent is entitled, “Multiscreen Personal Computer Display Method and Apparatus,” and it relates to a computer with multiple display capability. A user can simultaneously display documents using a singular processed video data signal source, on two or more screens. The '309 teaches a device termed a "translative video adapter", which is used on two or more screens to view and edit documents simultaneously. S/A asserts that Nintendo patent 7,786,997 entitled, "Portable Game Machine and Computer-Readable Recording Medium," infringes the '309 patent with its dual-screen.

Claim 1:

1. A multiple monitor video display method for use with a computer to produce a real-time display on a first monitor and a computer user selected predecessory display on a second monitor and comprising steps of:
processing computer program data into a ported source of display-ready first processed video data signal;
first intercoupling the ported source of first processed video data signal and the first monitor;
first displaying the first processed video data signal on the first monitor as the real time display;
second intercoupling the ported source of first processed video data signal and a translative video adapter (TVA) comprising further steps of:
first enabling the computer user to select a first sample of a first screen portion of the first processed video data signal second intercoupled with a TVA input port;
first storing first video data representing the first sample in a first memory;
advancing the computer program data to usually produce a second screen portion of the first processed video data signal for updating the real-time display on the first monitor;
first reading the first stored said first video data from the first memory;
first converting the first read said first video data signal into a first predecessory video signal; and,
second displaying the first predecessory video signal on a second monitor as the first predecessory display.

On August 4, 2015, the court entered a judgment in favor of Nintendo, finding Defendants did not infringe the ‘309 patent. The judgment was based on the claim construction order, which was found in favor of Defendants.

In the claim construction order, both parties asked the Court to construe "translative video adapter", which is used in Claims 1, 9, and 13 in the asserted patent. Plaintiff argued the TVA included software and/or hardware, but the Court declined to adopt this construction. Instead, the Court agreed with Nintendo that the TVA should be construed to mean an accessory device. The Court stated, "the term TVA appears in Claims 1 and 9 as a structure - as a physical device to be intercoupl[ed] with data signal and a monitor - not as a function."
