US Court of Appeals for the Federal Circuit Opinions | Synchronoss Technologies, Inc. v. Dropbox, Inc. | Docket: 19-2196 Opinion Date: February 12, 2021 Judge: Jimmie V. Reyna Areas of Law: Intellectual Property, Patents | The Synchronoss patents describe a system for synchronizing data across multiple systems or devices connected via the Internet and a “method for transferring media data to a network coupled apparatus.” The system generally involves one device or system that utilizes a first sync engine, a second device or system that utilizes a second sync engine, and a data store. In an infringement suit against Dropbox, the district court held that all asserted claims in the patent are either invalid under 35 U.S.C. 112, paragraph 2, or not infringed. The Federal Circuit affirmed the findings of invalidity and non-infringement and did not address Dropbox’s claims of ineligible subject matter. The asserted claims of one patent “are nonsensical.” Adopting Synchronoss’s proposal would require rewriting the claims. With respect to another patent, the claim term “user identifier module” does what the definiteness requirement prohibits; the term does not correspond to “adequate” structure in the specification that a person of ordinary skill in the art would be able to recognize and associate with the corresponding function in the claim. With respect to the third patent, Dropbox does not directly infringe by “using” Synchronoss’s claimed system. | |
