Samsung Electronics Co Ltd has been cleared on its use of graphics chip
technology owned by Nvidia Corp without permission, in a US
International Trade Commission ruling on Friday.
Judge Thomas Pender
said Samsung did not infringe two Nvidia patents, and while it did
infringe a third, he ruled that patent is invalid because it was not a
new invention compared with previously known patents.
Nvidia
spokesman Robert Sherbin said the ruling will be reviewed by the full
commission, which will make a final decision on the dispute in February.
"We remain confident in our case," he said.
A spokeswoman for Samsung declined to comment.
Santa
Clara, California-based Nvidia filed a complaint against Samsung and
Qualcomm Inc at the ITC in September 2014. At the same time, Nvidia sued
the companies in federal court in Wilmington, Delaware.
The ITC
has the authority to stop the import of products that it determines
infringe a U.S. patent. Companies frequently sue at the ITC to win an
import ban and in district court to win damages.
Nvidia, which
said it invented the first graphics processing chip and released it in
1999, accused Korea's Samsung and San Diego-based Qualcomm of using its
patents on graphics chip technology without permission or compensation.
Nvidia
alleged the companies infringed its patents with Qualcomm's Snapdragon
processors and Samsung's Exynos processors and was seeking to prevent
the import of several Samsung products, including its Galaxy smartphones
and tablets.
Samsung has also gone on the offensive. It
countersued Nvidia last November in federal court in Virginia, also
alleging patent infringement. Samsung also sued one of Nvidia's
customers.
