Samsung, Rival Ink Deal Over Contested Wireless Charging Tech

Aug. 12, 2022, 4:30 PM

Samsung Electronics Co. and NuCurrent Inc. reached a licensing deal Friday to end a patent-infringement lawsuit, in which NuCurrent accused Samsung of ripping off designs for wireless charging technology.

NuCurrent CEO Jacob Babcock said Samsung agreed to purchase a license for two patent families covering technology meant to make wireless charging antennas more efficient—including reducing power loss, drained battery life, and high heat generated in the process.

The companies on Friday filed a stipulation to the US District Court for the Southern District of New York that “dismisses all claims in this action with prejudice.” The filing doesn’t disclose any further details of the settlement.

NuCurrent sued the electronics giant in 2018, accusing it of patent infringement and trade secret misappropriation. NuCurrent, a company that started as a project at Northwestern University, alleged that Samsung requested a presentation on NuCurrent’s wireless charging technology, only to copy the tech for smartphones like the Galaxy S7 and S8.

Samsung responded by challenging the patents at the Patent Trial and Appeal Board. A New York federal judge blocked NuCurrent’s attempt to squash the board’s validity reviews by claiming that, under a nondisclosure agreement, any litigation over the patents must happen in a New York court.

In 2021, the PTAB invalidated claims in several NuCurrent patents, and the Federal Circuit upheld those decisions in July. The federal district court case has been on hold pending the outcome of the contested PTAB reviews.

Representatives and counsel for Samsung didn’t immediately respond to requests for comment.

Caldwell Cassady Curry PC represents NuCurrent. Paul Hastings LLP represents Samsung.

The case is NuCurrent, Inc. v. Samsung Electronics Co, Ltd., S.D.N.Y., No. 19-cv-00798.
