U.S. Patent No. 8,313,379: Video game system with wireless modular handheld controller
Issued November 20, 2012, to Nintendo Co., Ltd.
Priority Date: August 22, 2005



Summary:
U.S. Patent No. 8,313,379 describes the Nintendo Wii system. The Wii incorporation of motion controls into a video game system. Motion controls were not a new concept in video games, but the Wii certainly push motion controls into the mainstream. The Wii utilized a small remote and IR sensor bar to track a users movement. The IR sensor bar would be place usually on top of or below the television. A user would point the Wii remote in the direction of the television/sensor bar, and the Wii would generate a cursor on the TV in the corresponding area. When the user moved the remote, the cursor would follow. The Wii remote used accelerometers and infrared detection to determine its position in 3D space when pointed at the sensor bar. Calculating position in a 3D space is essential for games that require movement along a Z axis, such as a boxing game. Despite the complexity it took to track a user's movement, the motion controls were simple to understand. 

The Wii was a hugely successful console for Nintendo, selling around 100 million units. A big reason for the Wii's success was the accessibility. The motion controls made playing video games simple for the non-gamer. A person could easily understand that to play a golf game only required swinging the Wii remote like a golf club. The Wii had a significant impact on the video game industry. Shortly after the Wii launched, Microsoft and Sony introduced their versions of motion controls. Nintendo still uses a form of motion control in its current system, the Nintendo Switch, though the system does not require motion controls to operate. 


Abstract:
A home entertainment system for video games and other applications includes a main unit and handheld controllers. The handheld controllers illumination emitted by emitters positioned at either side of a display, and information derived from the sensed illumination is used to calculate the orientation of the controllers. The controllers can be plugged into expansion units that customize the overall control interface for particular applications including but not limited to legacy video games. Further, the controllers can be used in one-handed or two-handed modes of operation.

Illustrative Claim: 
1. A handheld controller operable in a one hand mode of operation and a two hand mode of operation, said controller for use in wirelessly communicating with an electronic game machine having an associated display screen, a first light emitting marker and second light emitting marker each mounted spaced from, but in the vicinity of, the display screen, said handheld controller comprising: an elongated housing having an upper surface, a lower surface, a forward end, a rearward end and a longitudinal axis defining at least one longitudinal center line, and sized to be operable by one hand of a user; a first set of game controls proximate said forward end of said housing; a second set of game controls proximate said rearward end of said housing; said first set of game controls and said second set of game controls being operable in use in a two hand game playing mode of operation, wherein during said two hand game playing mode said first set of game controls are disposed so as to be actuated by one thumb of a user and said second set of game controls are disposed so as to be actuated by the other thumb of the user, and wherein said first and second sets of game controls are actuated in use by the cooperative action of the user's thumbs; the lower surface of said housing having a concave portion provided with a trigger switch; a processor enclosed within said housing; an imaging device located in said forward end of said housing at least substantially aligned with said longitudinal center line and including a filter, a lens, an image sensor and an image processing circuit, wherein the image sensor, in use, detects light from the first light emitting marker and the second light emitting marker and generates image data, and wherein the image processing circuit, in use, receives and processes said image data and generates position data related to positional coordinates of the first light emitting marker and the second light emitting marker, and wherein the image processing circuit outputs the position data to said processor; at least said trigger switch and said imaging device being used in a one hand game playing mode of operation, wherein game play is controlled by the user holding the controller in one hand; linear accelerometer circuitry for detecting acceleration of the controller along each of three axes and for generating acceleration data along each of said three axes, said linear accelerometer circuitry being, in use, in communication with said processor; and a wireless communication device disposed within said housing and operatively connected to said processor and operable, in use, to transmit signals to said electronic game machine representing operational states of at least said first set of operational controls, said second set of operational controls, said trigger switch, said position data, and said acceleration data.

Case Update: Bandspeed, Inc. v. Sony Electronics, Inc., et. al.
United States District Court for the Western District of Texas
Case No: A-11-CV-771-LY, Filed Aug. 7, 2009


This case was originally filed in 2009 over alleged patent infringement of wireless communication technology.  Bandspeed, Inc., brought suit against Sony Electronics, Nintendo of America, and Apple, Inc. (among others), claiming that their patents were being infringed upon.  The two patents in question are U.S. Patent No. 7,027,418 ("Approach for Selecting Communications Channels Based on Performance") and 7,570,614 ("Approach for Managing Communications Channels").  Since our initial report the case has been transferred to the Western District of Texas and a second, related case was filed against Acer, Inc., as well as other defendants.  The two cases have since been consolidated by the court.  The case is still in the discovery phase, and nothing new has been filed since June 18, 2012.  As the case continues to develop, we will provide updates as to its status.
Nintendo v. Niu
United States District Court for the Western District of Washington
Case No. c-n10-791k, filed May 11, 2010.

This case arose from copyright and trademark infringement on the part of Mr. Kevin Niu.  Mr. Niu developed and sold game copiers for Nintendo’s DS and Wii products.  These copiers allowed purchasers to copy software from a game cartridge or disc in order to fool the console into thinking that an authorized copy of the game was being played, rather than a copy.


As of July 14, 2011, a settlement agreement was reached in which Mr. Niu confessed judgment in favor of Nintendo and authorized the Court to enter judgment in the amount of $200,000.  On August 29, 2011, the Court entered a Notice of Voluntary Dismissal with Prejudice.
Impulse v. Nintendo et. al.
United States District Court for the Northern District of Ohio
Case No.: 11-CV-02519-JG; filed November 11, 2011


Impulse originally filed suit against Nintendo, EA, Ubisoft, THQ, Konami, Majesco and Namco Bandai claiming infringement of patent for an, “interactive system measuring physiological exertions.”  The complaint outlined that fitness titles such as “EA Sports Active Personal Trainer” and peripherals such as the “Wii Fit Plus” and the “Wii Balance Board”.  On October 23, 2012, the case was dismissed with prejudice as to all claims against the game developers but without prejudice as to all claims made by the defendants against Impulse.
Impulse Technology Ltd. v. Nintendo of America, Inc. et al. 
 U.S. District Court for the Northern District of Ohio
Case No. 1:11-cv-02519

On November 11, 2011, Impulse Technology Ltd filed a complaint against Nintendo, EA, Ubisoft, THQ, Konami, Majesco, and Namco Bandai, alleging that they infringed upon its patent for an "interactive system measuring physiological exertion."  According to the complaint, each of the defendants has already received a letter giving notice of the patent and is allegedly willfully, deliberately, and intentionally infringing upon its rights.  Thus, Impulse alleged that each should be held liable for direct infringement, contributory infringement, and inducing of infringement.  In its complaint, Impulse claims that several of Nintendo's Wii products, including the Wii console,Wii Remote, the Wii Balance Board, and the Wii Fit Plus, include the patented technology.  Impulse also identified several games made by the defendants that "incorporated technology for measuring physiological exertion for use with the Wii."  The accused games include titles such as EA Sports Active Personal Trainer, Gold’s Gym Dance Workout, The Biggest Loser, Dance Dance Revolution Hottest Party 3, Zumba Fitness 2, and ExerBeat.  Impulse argued a system covered by at least one claim of the patent is created when one of the accused games is played on a Wii and displayed on a monitor. As a remedy, Impulse requested a permanent injunction and other damages.  

We will continue to follow this case and post updates as they become available to us.

As we last reported here, Motiva LLC has previously accused Nintendo Co., Ltd of infringing U.S. Patent No. 7,292,151 (‘151 Patent). The ‘151 Patent, entitled “Human Movement Measurement System,” is generally directed to a system for measuring human body movements for exercise and physical rehabilitation, and Motiva alleged that Nintendo’s Wii Fit product was an infringement.

Its previous efforts at enforcement stalled when the patent underwent reexamination at the PTO, but Motiva has just added a new chapter to the story. Last week, Motiva filed a complaint with the International Trade Commission (ITC), accusing Nintendo of infringing both the ‘151 Patent and a continuation application (U.S. Patent No. 7,492,268). The essential claims remain the same. Motiva claims that its patents cover the human movement tracking employed by the Wii Fit.

The alternative venue is not an uncommon one for asserting patents, and does not rule out or obviate parallel district court proceedings (although one can be stayed for the other).

In an ITC action such as this, a complainant alleges that some other person (a respondent) is importing goods that is otherwise harming an existing U.S. (domestic) industry. If the ITC concludes that such harm is being done, the ITC can issue an Exclusion Order, instructing U.S. Customs to block the future importation of goods that do the harm. To a company whose manufacturing facilities are located outside the U.S. (true for many consumer products companies these days), such an Exclusion Order can be every bit as painful as a district court injunction.

An ITC action is similar to a district court action in many ways. There is a complaint, there will be discovery (the Federal Rules of Civil Procedure are adopted at the ITC for many aspects of case management), there are motions, and there will be a hearing that is conducted much like a trial.

There are differences as well. Most notably, an ITC action is much faster than a typical district court action. In the ITC, a typical proceeding is scheduled for completion in just over a year (can be a bit longer for "complex" cases). The compressed schedule puts pressure on everyone, but the pressure usually affects the accused infringer more, since they do not control the timing of when the complaint is filed.

Another difference is the presence of a third party in the case. Unlike a district court action, an ITC investigation will also have an Investigative Staff Attorney, who is there to represent the interests of the citizens of the U.S. The Investigative Staff can participate in the case much like a party, reviewing discovery, asking questions, and filing responses to motions and objections.

Another difference is at the outcome of the case. The ITC cannot award monetary damages, and cannot redress past infringement. Instead, the remedy is the Exclusion Order, which will only affect attempted importations after the Order takes effect. Additionally, when an Exclusion Order is issued, the President of the United States has a period of time in which to review the case and reject it. Such a rejection is not common, but it can be made, for example, if the President deems that excluding the importation would unduly harm international relations.

We'll keep you posted as to further developments, and in the meantime, please drop us a line if you have any questions about the case or the ITC.
