STT WebOS, Inc. v. ByteDance Ltd. et al — Court denies ByteDance’s motion to seal NDA and patent-negotiation materials, ordering unredacted refiling

Background

STT WebOS, Inc. sued ByteDance Ltd. and related defendants in the Northern District of California, San Jose Division, and the case proceeded to an initial case management conference at which the parties agreed that WebOS could file a second amended complaint. ByteDance then moved to seal its opposition to WebOS's now-mooted motion for leave to amend, along with related exhibits: portions of the opposition brief (ECF No. 132-3), Exhibit 15, a nondisclosure agreement between WebOS and a ByteDance affiliate, in its entirety, Exhibit 16, email communications regarding patent negotiations, in its entirety, and portions of Exhibit 17, an email chain between counsel for the parties.

ByteDance argued that disclosure would create a substantial risk of competitive harm by revealing confidential negotiation strategies, expose personal information of its employees, and violate the parties' agreement that the NDA and related correspondence would remain confidential and would not be used in the litigation. WebOS objected that the competitive-harm assertions were generalized, that ByteDance had placed the materials at issue by relying on them in its opposition, and that wholesale sealing was not narrowly tailored because some documents contained nonconfidential material. WebOS's opposition was filed two days after the deadline set by Civil Local Rule 7-11(b), but the court exercised its discretion to consider the arguments while directing WebOS to comply with the local rules in future filings.

The Court’s Holding

The court held that the compelling-reasons standard governed the motion. Motions that are more than tangentially related to the merits may be sealed only upon a showing of compelling reasons, and motions for leave to amend and their corresponding exhibits qualify because the outcome of the motion may change the foundations of the lawsuit. The movant therefore bears the burden of overcoming the presumption of public access with compelling reasons that outweigh the general history of access and the public policies favoring disclosure.

Applying that standard, the court denied each request. As to Exhibit 15, the court found the NDA to be a cookie-cutter agreement with cookie-cutter provisions and was not convinced that public disclosure would adversely affect ByteDance's future negotiation prospects; seeking to seal the entire agreement also failed the obligation to narrowly tailor sealing requests to specific portions containing truly confidential and sensitive information. The same deficiency defeated the requested redactions of the opposition brief and of Exhibit 17, because those portions all related to the NDA.

The court separately denied sealing of Exhibit 16, the patent-negotiation email. The only contact information in the exhibit was the corporate email addresses of two ByteDance employees, which hardly gave rise to a privacy interest sufficient to defeat the strong presumption of public access, and the email's boilerplate confidentiality provision referred to WebOS's confidential information, not ByteDance's, because the email was sent from WebOS to ByteDance. The court ordered the motion to seal denied, directed ByteDance to refile the opposition and supporting exhibits without the proposed redactions by November 19, 2026, and terminated ECF Nos. 132 and 133.

Key Takeaways

• Materials connected to a motion for leave to amend are more than tangentially related to the merits, so sealing them requires compelling reasons, not merely good cause.
• A generalized assertion that disclosing a standard-form NDA would harm future negotiations does not overcome the presumption of public access.
• A request to seal an entire NDA must be narrowly tailored to specific provisions containing genuinely confidential and sensitive information.
• Two employees' corporate email addresses did not create a privacy interest strong enough to defeat the strong presumption of public access.
• The court considered WebOS's untimely opposition as a matter of discretion while directing future compliance with the local rules.

Why It Matters

The order applies public-access principles concretely to materials arising from patent negotiations, distinguishing genuine confidentiality concerns from boilerplate agreements and generalized claims of competitive harm. It confirms that a confidentiality agreement, standing alone, does not establish good cause—much less compelling reasons—to seal documents connected to an amendment motion.

The document-by-document analysis underscores that each sealing request must be supported and narrowly tailored on its own terms. The ruling decides only public access to the opposition and exhibits, leaving the parties' agreement to file a second amended complaint intact and requiring an unredacted refiling rather than resolving the merits of any patent claim.
