Judge Maddox said on the record during a hearing Tuesday that she anticipated granting preliminary injunctive relief in Vyne v. Henry Schein, a step that would restrict how Vyne Dental can market, sell or distribute software with write access to Dentrix databases and would also limit actions by Henry Schein One.
The anticipated order would require National Electronic Attachment, Inc.'s Vyne Dental to deprecate software and software functions capable of write access to Dentrix databases. It would also stop Henry Schein One, LLC from disabling Vyne Dental software and software functions that do not write back to Dentrix databases, and from denying printer-driver access to customers' electronic health information stored in those databases.
The hearing pointed to a split result in the underlying fight. Henry Schein One won a CFAA claim tied to write-back behavior, while Vyne had already been using a printer-driver method to read protected data, an issue linked to 7,000 practices. That makes the likely injunction more than a routine remedy: it would redraw the boundaries of what the software can do for a large number of dental offices while the case moves forward.
The dispute has become the biggest information blocking court development since RTMS v. PCC, and the court is still working through the practical questions that decide whether any injunction can actually function. Henry Schein filed a post-hearing submission on technical feasibility, compliance period and bond, and Vyne filed a reply. Some briefs tied to the parties' arguments have been filed, but not all of them, because the rest were sealed without a redacted version available.
That sealed record leaves the court to sort out a case that turns on a narrow but consequential distinction: software that writes back to Dentrix databases and software that only reads. With the judge already signaling preliminary relief for both sides, the next phase is likely to be defined less by broad legal theory than by whether the technical restrictions can be implemented without cutting off access that the court appears ready to preserve.
