Aliso Viejo’s SenoRx Inc., maker of devices to diagnose and treat breast cancer, is being sued by Hologic Inc., a Massachusetts maker of mammography and other medical equipment.
Cytyc Corp., which Hologic bought last year, is suing SenoRx for alleged patent infringement of devices used to deliver targeted radiation to a tumor.
Hologic is seeking unspecified damages and an injunction against SenoRx.
SenoRx said it is “confident in its proprietary intellectual property and intends to vigorously defend itself.”
In May, SenoRx got Food and Drug Administration approval for its Multi-Lumen Radiation Balloon Applicator, which is used to deliver targeted radiation to breast cancer.
The company went public early last year, raising $45 million. SenoRx has a market value of about $150 million.
Hologic counted a recent market value of nearly $9 billion.
