Integra’s HyperBranch Motion Defeated for Now

HyperBranch Medical Technology, Inc. has defeated a motion by Integra LifeSciences to preliminarily enjoin HyperBranch from selling its Adherus AutoSpray Dural Sealant product.

Background

The backstory here is that in late 2013/early 2014 Integra Lifesciences acquired Duraseal from Covidien for the princely sum of $235million, as we reported at the time, here. Then along came HyperBranch with its Adherus AutoSpray Dural Sealant, which it began selling in the United States in July 2015 after receiving FDA approval. In September 2015, Integra sued HyperBranch for alleged patent infringement in the U.S. District Court for the District of Delaware. Integra also filed a motion seeking a preliminary injunction to prevent HyperBranch from selling Adherus AutoSpray Dural Sealant during the pendency of the lawsuit. Now (On September 29, 2016), Chief Judge Leonard P. Stark has adopted the Report and Recommendation of Magistrate Judge Christopher J. Burke and denied Integra’s motion.

Status

Rejecting Integra’s argument that it would suffer irreparable harm as a result of HyperBranch’s alleged patent infringement, the Court found compelling evidence that the AutoSpray product is an attractive choice over DuraSeal due to a feature that undisputedly has nothing to do with the asserted patents, namely its applicator. This evidence reportedly shows that the DuraSeal applicator was associated with significant problems that are not presented by the Adherus applicator. Most significantly it found that the applicator advantage of the Adherus system over DuraSeal’s would be an important reason (perhaps the primary reason) why physicians and hospitals would choose the AutoSpray product over the DuraSeal product.

The Court also found that the public interest favors keeping Adherus AutoSpray Dural Sealant on the market during the pendency of the litigation. Citing testimony from three neurosurgeons with a combined 93+ years of experience, who “each expresse[d] a clear preference for the AutoSpray product,” along with documents from Integra (and its predecessor-in-interest, Covidien) that were “rife with references to the AutoSpray product’s improved applicator [and] to unresolved problems with DuraSeal,” the Court provided its rationale:

(1) there are only two FDA-approved dural sealant products for cranial procedures that are available in the United States market-Integra’s product and HyperBranch’s product; (2) the products’ use has a real effect on the health of patients who have undergone serious surgical procedures; (3) the record indicates that at least some number of physicians prefer HyperBranch’s product to Integra’s product (and does not contain much, if any, evidence regarding surgeons who prefer the DuraSeal product over the AutoSpray product); and (4) the record suggests that the DuraSeal product has deficiencies that the AutoSpray product does not suffer from.

The lawsuit will continue, with a trial scheduled to begin on April 16, 2018. In responding to the complaint, HyperBranch has denied Integra’s infringement allegations, asserted various defenses, including invalidity of the patents at issue, and requested an award of its attorneys’ fees and other litigation costs. HyperBranch intends to continue to defend itself vigorously against Integra’s claims and is confident that it will prevail on the merits.
