Our Successes in Patent Jury Trials

For our clients who have asserted their patent rights in the face of infringement and other unlawful competition, we have procured multimillion-dollar judgments and jury verdicts.

Likewise, we have successfully defended clients whose market practices have been challenged by patent owners who unfairly seek to dominate the field.

These are three of many favorable outcomes we have been pleased to deliver to our clients.

Exergen Corporation v. Kaz USA, Inc.

United States District Court for the District of Massachusetts

Sunstein obtained a verdict of $14.6 million after a two-week jury trial for infringement of Exergen’s patents for temporal artery thermometers.  The jury found infringement and confirmed the validity of every one of the twelve asserted patent claims, and awarded both lost profits and a reasonable royalty.

Abbott Laboratories v. Syntron Bioresearch, Inc.

United States Court of Appeals for the Federal Circuit
United States District Court, Southern District of California

United States District Court, Southern District of California Sunstein represented Abbott Laboratories in patent infringement litigation concerning immunoassay technology against Syntron Bioresearch, Inc. in the United States District Court for the Southern District of California.

After a four-week jury trial and an appeal to the Court of Appeals for the Federal Circuit, we prevailed on our claim of patent infringement and secured a permanent injunction from the trial court against further infringement. The case then settled during the damages phase.

Gates Formed-Fibre Products, Inc. v. Delaware Valley Corp. and Dominic Paul DiMaggio, Jr.

United States District Court for the District of Massachusetts

Sunstein obtained a verdict of no liability for Delaware Valley and Dominic Paul DiMaggio, Jr., who were accused of patent infringement. Gates asserted that Delaware Valley’s process for making its fused-back carpeting infringed a process patent and that our client’s fused-back material infringed a product patent. Gates sought damages of more than $36 million and an injunction against Delaware Valley.

After a four-week trial, the jury determined that our clients were not liable because the patents were invalid. The jury’s verdict was affirmed by the Court of Appeals for the Federal Circuit.

Comair Rotron, Inc. v. Matsushita Electric Corporation of America et al.

United States Court of Appeals for the Federal Circuit
United States District Court for the District of New Jersey

Sunstein secured at trial a $25 million judgment for willful patent infringement, including treble damages and attorneys’ fees, and defended it on appeal for our client, Comair Rotron, Inc.

In a related case, Rotron, Inc. v. United States International Trade Commission, we obtained a ruling from the Court of Appeals upholding the validity of our client’s patent and directing the International Trade Commission to enter an appropriate exclusion order against infringing products imported by Matsushita Electric Corporation of America.
