Sarif Biomedical accused Accuray (NSDQ:ARAY) of infringing 1 of its patents with the CyberKnife radiosurgery device for cancer, which uses targeted radiation blasts to destroy tumor cells.

Tool, Texas-based Sarif’s patent covers ""Computer-Assisted Microsurgery Methods and Equipment." The medical device company alleges that Accuray’s device trespasses on that intellectual property, according to the lawsuit.

The lawsuit, filed Jan. 28 in the U.S. District Court for Delaware, seeks a judgment of infringement and an injunction barring further infringement, damages, "[a] finding that this is an exceptional case," pre- and post-judgment interest and legal costs.

"At this time, we do not have enough information to estimate what, if any, financial impact this claim will have," Accuray said this week in a regulatory filing.
