STIPULATION OF REMOVAL OF LIBERTY CYCLER 

FUNCTIONALITY RELATING TO, AND DISMISSAL OF U.S. 

PATENT NO. 5,431,626 

1 Case No. C 07-01359 PJH (JL) 

WHEREAS, the Court has withdrawn its construction of the claim limitation “pressure 

conveying element” as recited in U.S. Patent No. 5,431,626 (“the ’626 Patent”) and has invited 

further briefing regarding the proper construction of this limitation, the limitation “pressure 

transfer element,” and whether the claims reciting these limitations are indefinite; 

WHEREAS, Plaintiffs seek to dismiss their allegations that any version of the LibertyTM 

peritoneal dialysis cycler infringes the claims of the ’626 Patent subject to Fresenius’ agreement 

not to employ certain designs as described below before the expiration of the ’626 Patent;

WHEREAS, during the development of the LibertyTM Cycler, Fresenius engineers 

considered and rejected using an inflatable air bag to actuate the cycler’s safety bar in favor of 

using a pair of pneumatically actuated cylinders to actuate the cycler’s safety bar; 

WHEREAS, during the development of the LibertyTM Cycler, Fresenius engineers 

considered and rejected using an inflatable air bladder behind the pump face in favor of placing 

an inflatable air bladder in the door; 

WHEREAS, separately and apart from the foregoing recitals, the parties agree to dismiss 

all claims and counterclaims with respect to claims 34, 36-38, 41, 44, and 45 of U.S. Patent No. 

5,431,626;

NOW, THEREFORE, the parties and their counsel of record stipulate as follows: 

• Defendants agree that they will not make, use, sell, or offer for sale within the United 

States or import into or export from the United States any peritoneal dialysis machine 

using an inflatable air bag to actuate the cycler’s safety bar or using an inflatable air 

bladder behind the pump face of the cycler or mere colorable variations thereof until 

after the expiration of U.S. Patent No. 5,431,626; 

• Plaintiffs agree the current commercial version of the LibertyTM Cycler is a peritoneal 

dialysis machine that does not use an inflatable air bag to actuate the cycler’s safety 

bar or use an inflatable air bladder behind the pump face of the cycler; 

• Although Plaintiffs contend the current commercial version of the LibertyTM Cycler 

and prior versions of the LibertyTM Cycler infringe the claims of U.S. Patent No.

2 Case No. C 07-01359 PJH (JL) 

5,431,626 under the doctrine of equivalents and Defendants disagree with that 

contention, Plaintiffs dismiss from this suit, without prejudice and subject to the 

provision immediately above, U.S. Patent No. 5,431,626;

• Although Defendants contend the asserted claims of U.S. Patent No. 5,431,626 are 

not infringed and are invalid and Plaintiffs disagree with these contentions, 

Defendants dismiss from this suit, without prejudice, and subject to the provisions 

immediately above, U.S. Patent No. 5,431,626; 

• The parties agree that each shall bear its own costs and attorneys’ fees as to such 

claims, defenses and counterclaims; and

• The parties agree that this stipulation is not an injunction but reserve all rights and 

remedies to enforce its terms. 

IT IS SO ORDERED.
