Datanet v. Dropbox: real-time file-management patents asserted in Waco

2022–2024

LowStatus: ResolvedProduct: Core syncYear: 2022

Datanet LLC sued Dropbox in October 2022 over two patents on automatic real-time file management; Dropbox challenged the patents at the patent office, and the district-court docket closed in March 2024.

What happened

Datanet LLC sued Dropbox in the U.S. District Court for the Western District of Texas, Waco Division (Datanet LLC v. Dropbox, Inc., No. 6:22-cv-01142), filing on 31 October 2022. Datanet asserted U.S. Patent Nos. 8,473,478 and 9,218,348, both titled 'Automatic Real-Time File Management Method and Apparatus,' against Dropbox's file-management functionality — placing it among the patent-assertion suits filed in that same district against Dropbox's core sync product.

Dropbox contested the claims on two fronts at once: defending the case on the district-court docket and, separately, filing for inter partes review at the U.S. Patent and Trademark Office (IPR2024-00079) to challenge the validity of the asserted patents. The district-court docket closed on 28 March 2024, roughly seventeen months after filing.

What public sources reviewed for this entry do not establish is how the case actually ended — whether by settlement, dismissal, or another terminating event — and no such claim is made here. What is documented is the filing date, the patents and district asserted, Dropbox's parallel IPR challenge, and the date the docket closed; beyond that, the outcome is not confirmed in public sources.

Impact

Datanet is another entry in the long sequence of patent-assertion-entity suits filed against Dropbox in the Western District of Texas, targeting the file-management features at the heart of its service. As with several similar matters, Dropbox paired its district-court defense with an inter partes review aimed at invalidating the asserted patents at the agency level.

Dropbox's Response / Official Position
