Representative Cases

In Natera, Inc. v. Sequenom, Inc. (N.D. Cal.), Mr. Barari was lead counsel representing a declaratory judgment plaintiff asserting that patent-in-suit relating to non-invasive prenatal genetic testing is not valid and not infringed. He obtained a summary judgment of invalidity on the grounds that the patent-in-suit is not directed to patentable subject matter under 35 U.S.C. § 101. The finding was unanimously affirmed by the Federal Circuit Court of Appeals in a consolidated appeal, Ariosa Diagnostics, Inc. et al. v. Sequenom, Inc., 788 F.3d 1371 (Fed. Cir. 2015), cert. denied 136 S. Ct. 2511 (2016).

In AntiCancer, Inc. v. Carestream Health, Inc. (S.D. Cal.), Mr. Barari defended a medical equipment company against claims of infringement of patents concerning the use of cancer cells transformed to express green fluorescing proteins. The case settled favorably after a partial summary judgment of non-infringement was granted in favor of his client.

In Genetic Technologies Limited v. Natera, Inc. (D. Del. and N.D. Cal.), Mr. Barari was lead counsel defending a genetic testing company against claims of patent infringement by a non-practicing entity. After obtaining transfer of the matter to the Northern District of California, 2014 WL 1466471 (D. Del. Apr. 15, 2014), the plaintiff dismissed all claims in a “walk away” agreement without payment.

In Netlist v. Diablo (N.D. Cal.), Mr. Barari represented plaintiff in a trial of trade secret, patent and trademark claims involving HyperCloud® LR-DIMM memory module technology.
