Unreported / Non-Citable
Background
Railware, Inc. sued the Peninsula Corridor Joint Powers Board (Caltrain) in the Northern District of California. In the course of claim construction proceedings, Railware filed an expert report as Exhibit D and moved to seal portions of it. Railware sought to seal its own purported confidential information, highlighted in yellow at pages 10 through 12 and 14 through 15 of the exhibit, and separately moved for the court to consider whether to seal Caltrain's purported confidential information, highlighted in green at pages 11 through 12.
The motions, docketed as ECF Nos. 156 and 157, required the court to decide which legal standard governed the sealing of claim construction materials. Under Ninth Circuit law, materials more than tangentially related to the merits may be sealed only upon a showing of compelling reasons, while other materials require only good cause. The court acknowledged an intra-district split on which standard applies to claim construction materials, citing conflicting decisions in Symantec Corp. v. Acronis, Inc. and Applied Materials, Inc. v. Demaray LLC.
The Court’s Holding
The court resolved the split by holding that claim construction materials are more than tangentially related to the merits of a case, reasoning that claim construction is often outcome determinative. It cited Federal Circuit authority describing claim construction proceedings as critical to infringement determinations. Accordingly, the compelling reasons standard governed, placing the burden on the movant to overcome the presumption of public access.
Applying that standard, the court granted Railware's motion to seal its own information, finding that the material related to the design and functionality of Railware's proprietary system and that Railware had shown competitive harm could result from public disclosure. The court also found the proposed redactions narrowly tailored, constituting only a small fraction of the expert report.
As to Caltrain's materials, the court admonished Caltrain for failing to file the supporting statement or declaration required by Civil Local Rule 79-5(f)(3) within seven days, warning that such a failure may result in unsealing without further notice. Nevertheless, the court reviewed the proposed redactions, which consisted of excerpts of a user manual including two screenshots of the system's user interface, and found compelling reasons to seal them as well, granting both motions in full.
Key Takeaways
- The court held that claim construction materials are more than tangentially related to the merits of a case, so the compelling reasons standard rather than the good cause standard governs requests to seal them.
- The decision takes a side in an acknowledged intra-district split within the Northern District of California on the proper sealing standard for claim construction materials.
- Railware's redactions were approved because they concerned the design and functionality of its proprietary system and were narrowly tailored to a small fraction of the expert report.
- Caltrain was admonished for failing to file the statement or declaration required by Civil Local Rule 79-5(f)(3) within the seven-day deadline, though the court still sealed its two user-interface screenshots.
- The ruling reinforces that parties seeking to seal must show competitive harm and narrow tailoring even when the opposing party fails to follow local sealing procedures.
Why It Matters
This order is notable for squarely addressing an intra-district split in the Northern District of California over whether claim construction materials are subject to the compelling reasons or good cause sealing standard. By siding with the compelling reasons approach, the court aligned itself with decisions treating claim construction as central to the merits, given its frequently outcome-determinative role in patent cases.
The decision also illustrates that procedural noncompliance with local sealing rules does not automatically defeat a sealing request when the underlying showing of competitive harm is satisfied, though the court made clear that future failures to comply with Civil Local Rule 79-5 could result in unsealing without further notice.
