The lawsuit filed against Nintendo concerning the Nintendo 3DS game console has finally been decided by a higher court. The verdict did not favor Tomita Technologies who filed the patent lawsuit back in 2011.

After several years of battling in court, the Japanese gaming company may finally relax on the patent lawsuit. The Federal Circuit Court ruled that Nintendo 3DS did not infringe the patent of Tomita's glasses-free 3D display technology.

The legal battle started when retired Sony engineer and Tomita Technologies founder, Seijiro Tomita, accused Nintendo of using his glasses-free 3D technology to create the 3DS without paying royalties.

Tomita won its lawsuit for the 3DS display technology in the lower court. The jury found Nintendo to be at fault, calling for $30.2 million to be paid as compensation to Tomita. However, an appeal was filed, and the decision of the lower court was overturned during a retrial, according to Gamasutra. A New York judge ruled that Nintendo 3DS performs differently from Tomita's patent.

The case was then moved to a higher court. The Federal Circuit court scrutinized the claim and defense of both parties involved. The main question at hand was not about 3DS allowing glasses-free stereoscopic images but mainly how the device joined two perspectives of a 3D image to create the illusion of depth, according to Engadget.

To know the difference, the court decided to perform two tests. One tested assessed whether the functions of the devices are similar, while the second test helped to determine whether the differences between the methods were substantial.

At the end of the test, the court ruled revealed that Nintendo 3DS and "the disputed limitation do not possess equivalent structures." Therefore, giving no room for the patent lawsuit to prevail, leaving the case to rest for good.
