    Pfizer doxycycline patent litigation

    Pfizer pursued International Rectifier and its Rachelle Laboratories operations over an alleged infringement involving a manufacturing process for generic doxycycline. The dispute ultimately produced a reported $55.8 million judgment and led International Rectifier to surrender or divest its pharmaceutical, animal-health, feed-additive, and related biochemical assets.
