The U.S. International Trade Commission has announced that a complaint was filed by Ericsson Inc. and related companies regarding the alleged infringement of several U.S. patents by Samsung Electronics and its subsidiaries. The complaint claims that certain electronic devices with wireless connectivity, such as mobile phones and smart TVs, are being imported and sold in the U.S., violating the patents. The Commission has decided to investigate these claims to determine if there has indeed been a violation, which could lead to import bans or other legal actions against the respondent companies. This investigation does not involve the Office of Unfair Import Investigations as a party.
Simple Explanation
The government is checking if some gadgets like phones and TVs from a company might be using secret ideas (called "patents") from another company without permission, which could get them in trouble.
