CardiAQ Valve Technologies, Inc. v. Neovasc Inc.
Won a $70 million jury verdict for our client, CardiAQ. CardiAQ designed a transcatheter mitral valve replacement device that was the first ever to be placed in a human and hired Neovasc to help assemble prototypes under a non-disclosure agreement. Neovasc's lead engineer began designing a directly competing device while working on CardiAQ's prototypes, but decided not to tell CardiAQ as their relationship continued for six more months, during which time CardiAQ shared numerous confidential designs. After the judge enhanced damages and awarded interest, the judgment totaled $112 million, which our client collected in full.

The parties settled before appeal, with Philips agreeing to pay $300 million and integrate Masimo technology in its patient monitors.
KFx Medical Corp. v. Arthrex, Inc.

Hundreds of thousands of rotator cuff surgeries are performed each year in the United States utilizing KFx’s patented technique.

We successfully convinced the district court that Otto Bock was unlikely to prevail on the merits of any of its claims and the district denied the preliminary injunction. The Federal Circuit affirmed.

Won an inventorship dispute for our client, Applied Medical. As part of a long patent infringement battle between Applied Medical and Covidien over single incision laparoscopic surgery devices, Covidien purchased the disputed license rights in Applied Medical’s patents and sued Applied Medical to add additional alleged inventors to Applied Medical’s patents. After a bench trial, the district court ruled in Applied's favor on all claims and held that no individuals associated with Covidien are inventors on any of the five Applied patents at issue.
United States v. Masimo Corp.
Successfully defended Masimo against former employees who alleged that Masimo submitted false claims to the government in connection with Masimo’s “Pronto” line of medical devices. These devices non-invasively measure total hemoglobin in the blood. Relators claimed the devices were worthless and doctors who used them should not have received any governmental reimbursement. We won a motion for summary judgment, which gave Masimo a complete victory without having to go to trial.

In the Matter of Certain Dental Implants
Successfully represented Nobel Biocare (the complainant) in an investigation asserting patents directed at dental implant design against two respondents. After defeating a motion for summary determination of invalidity, the case proceeded to trial where we secured multiple victories for Nobel.
