Judge Maddox Signals Preliminary Injunction in Henry Schein Dispute
Judge Maddox said he anticipated granting preliminary injunctive relief in henry schein v. Vyne during the hearing, putting immediate limits around Vyne Dental software tied to Dentrix databases. He said, “I anticipate granting preliminary injunctive relief in favor of both parties.”
The court’s plan would bar National Electronic Attachment, Inc. from marketing, selling or distributing software capable of write access to Dentrix databases, while also protecting Vyne Dental software that reads data without writing back. The judge’s remarks came as the court kept working through technical feasibility, the compliance period and bond issues.
Judge Maddox Hearing
Four injunction items were on the table: a bar on Vyne Dental software capable of write access to Dentrix databases, a requirement that Vyne Dental deprecate software and functions capable of write access, a bar on Henry Schein One disabling software and functions that do not write back to Dentrix databases, and an order blocking Henry Schein One from denying printer-driver access to Vyne Dental customers’ electronic health information stored in Dentrix databases.
Judge Maddox’s statement focused on software behavior, not the parties’ broader business dispute. Henry Schein One received a CFAA win on the write-back behavior, while Vyne’s printer-driver method for reading data remained protected.
Henry Schein One Submission
After the hearing, Henry Schein filed a post-hearing submission on technical feasibility, the compliance period and bond. Vyne then filed a reply. Those filings kept the court on the record while it sorted out how any order would work in practice.
The dispute has been described as the biggest information blocking court development since RTMS v. PCC. Some briefs and related materials were sealed without a redacted version, leaving the court’s written record incomplete for public review.
7000 Practices
The source says the printer-driver protection is intended to prevent the hemorrhaging of 7000 practices. That is the clearest operational number in the case: the court is not only drawing lines around access to Dentrix databases, but also deciding which software functions can keep running while the order takes shape.
For Vyne Dental customers, the practical question is which tools continue to read electronic health information and which tools lose write capability. The court’s next step will have to translate the judge’s stated intent into language that matches the technical setup, the compliance period and the bond terms already in play.
