The Johns Hopkins University (Baltimore) and Arrow International (Reading, Pennsylvania) reported winning a patent infringement suit against Datascope (Montvale, New Jersey) in the U.S. District Court in Baltimore.

Hopkins and Arrow had brought suit against Datascope charging infringement of patents relating to the Arrow-Trerotola Percutaneous Thrombolytic Device (PTD), used by interventionalists for treating hemodialysis patients.

The jury ruled that the Datascope ProLumen device infringed three patents owned by Hopkins and licensed by Arrow, and upheld their validity. The jury also awarded damages amounting to an 18% royalty on Datascope’s sales of the infringing device.

Hopkins and Arrow have asked the court to issue a permanent injunction against Datascope’s sales of the ProLumen.

Dr. Scott Trerotola, now with the University of Pennsylvania (Philadelphia), in the early 1990s invented the PTD, used to clean clotted dialysis grafts, while working at Hopkins. Arrow, having an exclusive license for the technology, recently celebrated the 10-year anniversary of device development, saying that tens of thousands of patients have been treated with the device.

Hopkins and Arrow were represented by attorneys with Amster, Rothstein & Ebenstein (New York), an intellectual property law firm.

Arrow develops disposable catheters and related products for critical and cardiac care.
