PXG founder Bob Parsons is suing TaylorMade as he believes the P790 irons infringe on his brand's patents.
The new P790 iron has “Speedfoam” injected into the cavity of the club, a liquid which turns to a soft foam to improve distance, forgiveness and feel.
PXG inject Thermoplastic Elastomer into their irons, a hard plastic substance, for similar benefits.
Parsons revealed the news via Twitter.
