Slack’s Attempt to Head Off Custom Emoji Patent Suit Dismissed

Slack Technologies Inc.’s lawsuit to clear its “emoji library” technology from potential patent infringement claims by Phoji Inc. was dismissed Thursday after a San Francisco federal court found Minneapolis-based Phoji didn’t have sufficient contacts with California to justify exercising jurisdiction over it.

Phoji makes an app that enables users to create “custom photo-based emojis,” which is covered by its U.S. Patent No. 9,565,149.
