As in Complaint:
Plaintiff alleges that defendant markets and manufactures Jay® Seating Products that include a fluid pad or cushioning component which includes microspheres and a lubricating substance such that the composition does not flow under gravity like a liquid but instead easily deforms under pressure and then stays in position until pressure is applied to deform it in a different way, thereby conforming to the user of the seating product, that infringes the above patents.

Plaintiff has recently filed case (2:12-cv-01219) against Blue Chip Medical Products on December 31, 2012, which is pending.
