Hulu LLC will again need to confront infringement claims for
a part of Sound View Innovations LLC’s presently expired patent after the
Federal Circuit sent the suit back to the district court for another look.
A California federal court was wrong in concluding that the term “buffer” in the patent case can’t cover a “cache,” the U.S. Court of Appeals for the Federal Circuit ruled in a precedential assessment.
However the Federal Circuit agreed with the U.S. District Court for the Central District of California’s case development in a patent covering methods for streaming media data over public networks, it told the lower court to revisit its utilization of the terms like “buffer” and “cache,” resuscitating a chapter in the long-running question among Hulu and Sound View Innovations.
Sound View Innovations sued Hulu in 2017 for infringing six licenses with Hulu’s web-based video-on-request products. A portion of the issues including one more patent grabbed the eye of the U.S. Patent and Trademark Office administration. Just this dispute, including U.S. Patent No. 6,708,213, remained at the Federal Circuit.
Hulu and Sound View Innovations fought at the California court over the significance of a downloading limit in one of the patent’s cases. The region judge sided with Hulu, finding that the case should allude to just a single buffer as opposed to including multiple. Hulu could not have infringed the patent since Sound View’s servers don’t download and retrieve data in the same buffer.
The Federal Circuit decided that the district’s court claim development was right in expecting that the downloading and retrieving acts need to include a similar buffer. Caches, however, which Sound View Innovations depended on for its infringement allegation, could likewise be buffers, the Federal Circuit found. Despite the lower court’s decision, the expressions “do not appear to be mutually exclusive, but instead seem to have at least some overlap in their coverage” in the patent.
