Integra LifeSciences v. HyperBranch Medical Technology


Cooley successfully defended HyperBranch Medical Technology against a patent infringement lawsuit filed by a competitor, Integra LifeSciences.


After a two-week trial in Delaware federal district court, a jury found in favor of HyperBranch on all claims and defenses.

The lawsuit, filed in 2015 just two months after HyperBranch launched its Adherus AutoSpray Dural Sealant product in the United States, originally contended that HyperBranch willfully infringed 109 claims in six patents through its manufacture, use and sale of its Adherus products. Integra also filed with its complaint a motion for a preliminary injunction asking the Court to enjoin HyperBranch from making and selling the accused Adherus products during the pendency of the case.

HyperBranch defeated Integra’s preliminary injunction motion in 2016 and continued to score victories throughout the subsequent litigation. After hearing six days of testimony from witnesses and viewing numerous exhibits admitted into evidence, the jury unanimously determined that the company did not infringe any of the remaining asserted patent claims, and that all of those claims are invalid.

HyperBranch is a medical technology company focused on delivering superior patient and physician experiences through products designed to minimize post-surgical complications.
