Inventor Jiro Takashima, 75, maintains that his Pro-State massager is a serious medical device (retailing for about $80), but his daughter-partner Amy Sung, 35, simultaneously markets it as a prostate sex-play toy called the Aneros at adult novelty stores (retailing for about $50). According to a June Houston Chronicle report, Takashima's booth at medical conventions is popular, but at sex expos, he and his daughter are "rock stars." However, since the Pro-State/Aneros was intended as a medical device, competing sex-toy makers have felt free to copy Aneros' design, and Takashima's lawsuit to stop them is now before a federal court in Houston.
