Apple wants OpenAI's late-filed testimony kept in the record for its injunction hearing
Apple told the court that OpenAI and io Products stretched an objection capped at five pages into nine pages that reargue its injunction request. Its answer is to keep every disputed filing in the record for the October 14 hearing on slowing OpenAI's hardware work.
The Product Desk

What happened
- Apple is suing former employees Chang Liu and Tang Tan, along with OpenAI and io Products, for trade secret misappropriation.
- Apple backed its injunction reply brief with five expert declarations, and the defendants objected that this was improper new evidence the court should partly disregard.
- Apple singled out a new eight-paragraph declaration from Liu as "the most egregious overreach" in the defendants' filing.
- When they filed Liu's declaration, the defendants asked that it count only if the court also considers the Apple evidence they challenged.
Why it matters
- cost If the court grants the injunction, OpenAI's hardware group works under limits for as long as the case runs, before any court has found that Apple's secrets were taken.
- constraint A judge who wanted to throw out Liu's testimony over the page limit would have to go further than Apple itself has asked.
- exposure Hiring from a rival's hardware group carries the same exposure: an employee's exit records, down to how a machine was returned, can become the evidence an injunction is argued on.
Chang Liu handed his iMac back to Apple with the data erased. Apple's filing puts the verb in quotation marks: Liu "wiped" the machine before returning it [7]. According to Apple, his new declaration gives his reasons for that. It also gives his reading of text messages with an Apple supplier and his account of using one confidential Apple file [7]. Apple's latest filing attacks that declaration and also asks the judge to consider it along with everything else [10].
The defendants called their filing an objection. According to Apple, it argued the merits, down to disputing whether one Apple expert, Dr. Runge, has a "basis to offer any analysis" [13]. They also attached documents countering Apple's claims [4]. The local rule Apple cites, 7-3(d)(1), lets a party object to new evidence in a reply but says the filing "may not include further argument on the motion" [5]. Apple wrote that the defendants' new arguments and evidence read more like a sur-reply than an objection, and that the defendants never sought leave to file a sur-reply [11]. By Apple's count, the objection and the declaration together ran nine pages against a five-page limit [8]. That is four pages over [14].
Apple's own filing has a similar gap between label and request. It is framed as a complaint about overreach. The relief it asks for is that nothing be struck: deny the defendants' request to set aside Apple's reply evidence, and decide the injunction on a full record with the defendants' new material included [10].
Set that request beside the condition the defendants put on Liu's declaration [9], and no party is asking for a split result. The two positions leave the judge two records to choose from. One is everything. The other is a narrower record with Apple's challenged reply evidence and Liu's explanation both left out [15].
The choice matters to OpenAI's hardware team because of what the injunction is for. Apple says the injunction would keep its trade secrets from being worked any deeper into OpenAI's hardware development while the lawsuit is pending [2]. The evidence ruling sets what the court weighs when it hears arguments on October 14 [12]. It does not decide the motion, and the filings as reported do not spell out what an injunction would order OpenAI to stop doing. I think Apple is betting that five expert declarations [3] hold up against eight paragraphs from Liu [6].
Outside the courtroom, this case is for the people who hire out of a rival's hardware group and then have to explain the hire when a lawyer asks. The evidence in dispute is the ordinary record of someone leaving a job. A hiring team can ask two questions about any such hire. One is whether the person's old devices went back intact or erased. The other is whether their contact with the old employer's suppliers, and any confidential file they opened, has a written account made at the time. A hire whose devices went back intact, with that account on file, leaves the least to explain. When a device went back erased and nothing was written down, the explanation comes later, as testimony, while a judge decides whether to read it. Liu's iMac went back erased, and his explanation reached the court as new testimony in the middle of a fight over page limits [7][8].
What to watch
- Whether the court rules on the strike request before arguments on October 14 or folds it into its injunction decision.
- Whether the defendants ask for leave to file a sur-reply, the step Apple says they skipped.
- The scope of any injunction the court issues, and what it would require of OpenAI's hardware development.

Apple's lawsuit accuses two former employees, Chang Liu and Tang Tan, along with OpenAI and io Products, of trade secret misappropriation.
- [2]
Apple has asked the court for a preliminary injunction, arguing it would prevent its trade secrets from becoming further embedded in OpenAI's hardware development while the case plays out.
- [3]
Apple filed a reply brief supported by five expert declarations; the defendants accused Apple of improperly introducing new evidence and asked the court to disregard some of the material.
- [4]
In their objection filing, OpenAI and the other defendants also submitted several documents countering Apple's claims.
- [5]
Apple's filing says Rule 7-3(d)(1) permits a party to object to new evidence in a reply brief but cautions that the filing "may not include further argument on the motion," and that the defendants used their filing to relitigate the merits of Apple's preliminary injunction motion.
- [6]
Apple calls a new declaration from Liu, comprising eight paragraphs of new testimony, "the most egregious overreach" in the defendants' filing.
- [7]
According to Apple, the defendants rely on Liu's new testimony to offer excuses for why he "wiped" (erased) all the data from his iMac before returning it to Apple, to argue about the meaning of text messages with one of Apple's suppliers, and to explain away his use of one of Apple's confidential computer files.
- [8]
Apple says the defendants' filing and Liu's declaration together run 9 pages, violating the limit that objections "may not exceed 5 pages of text."
- [9]
When the defendants filed Liu's declaration, they argued the court should consider it only if it also decided to consider the Apple evidence they were challenging.
- [10]
Apple asks the court to deny the defendants' request to strike any of Apple's reply evidence and to decide the preliminary injunction motion on a full record, including both Apple's reply arguments and evidence and the new arguments and evidence submitted with the defendants' filing.
- [11]
"Defendants' new arguments and evidence are more in the nature of a 'sur-reply' rather than an objection. But, Defendants did not seek leave to file a sur-reply."
- [12]
The court is scheduled to hear arguments on Apple's preliminary injunction request on October 14.
- [13]
According to Apple, the defendants dispute whether Dr. Runge has a "basis to offer any analysis."
- [14]
By Apple's count, the defendants' combined filing ran four pages over the five-page limit.
- [15]
Under the parties' stated positions, no one asks the court to consider one side's disputed material without the other's; the records on offer are the full record or one without Apple's challenged reply evidence and Liu's declaration.
