Slip a smartphone into a VR headset, and suddenly you're immersed in a virtual world. But here's a practical question: how do you interact with your phone's touchscreen when it's enclosed inside the headset?
That seemingly simple challenge became the center of a patent dispute between Google and DDC Technology.
In 2022, DDC Technology sued Google and several other companies for patent infringement. Google subsequently challenged the validity of DDC's patents before the Patent Trial and Appeal Board (PTAB), arguing that the inventions were obvious in light of earlier technologies.
On November 5, 2026, the U.S. Court of Appeals for the Federal Circuit upheld PTAB decisions concerning three DDC Technology patents (US 9,420,075, US 10,528,199, and US 11,093,001). While some patent claims had been found unpatentable the court upheld the Board's decision that Google had failed to establish the obviousness of other challenged claims.
The patents involve technology that allows users to operate a smartphone's touchscreen through controls located outside a VR headset. In assessing Google's challenges, the PTAB considered evidence beyond earlier technical disclosures, including similarities between Google's VR viewer and DDC's products and prototypes, as well as internal emails in which Google engineers praised the technology. The Federal Circuit agreed with the Board's assessment.
The case highlights an important aspect of patent law: determining whether an invention is obvious isn't always just about comparing technical documents. Real-world evidence, including industry recognition and indications of copying, can also play a meaningful role.
Sometimes, even a small button can become the center of a major patent dispute.
