Philips Healthcare (NYSE:PHG) plans to go another round with Zoll Medical Corp. (NSDQ:ZOLL) over automated external defibrillators, suing Zoll in Washington state over a new string of allegedly infringed patents.

Philips wants a jury to issue an injunction to keep Zoll from selling its AED Plus and AED Pro devices, as well as compensation for lost sales and legal fees.

The Netherlands-based device maker first sued Zoll over AED patents in June 2010, claiming infringement of a string of 15 patents related to the devices.

Zoll responded by counter-suing over 5 of its own patents a month later, accusing Philips' HeartStart MRx, HeartStart
XL, and HeartStart AED lines of infringement.

External defibrillators are big business for both companies. Each has touted lucrative contracts from the U.S government to supply the devices, which are used to shock the heart back to beating after a heart attack.

Zoll announced an important reimbursement win last month from the Centers for Medicare & Medicaid Services, which said it wouldn't limit reimbursement for the company's flagship LifeVest wearable defibrillator.
