Re: Arthrocare Suit - Delaware 

USDC-D. Del, - OA. No. 01-504-SLR 

Dear Perry: 

I have enclosed Smith & Nephew's supplemental invalidity responses for the 
independent claims asserted against the Electroblade and Saphyre products. These 
responses are subject to and made without waiving Smith & Nephew's previous 
objections to ArthroCare's discovery requests. We reserve the right to revise these 
responses as discovery proceeds. In particular, we reserve the right to revise these 
responses after we have received meaningful discovery on ArthroCare's claim 
construction and infringement contentions, and after the Court has construed the 
asserted claims. 


Veiy truly yours, 



CO

Smith & Nephew's Second Supplemental Response Re Invalidity 
In addition to its previous objections, and without waiving any of those 
objections, Smith & Nephew also objects to providing its invalidity contentions at this 
time, since ArthroCare has refused to provide any of its contentions with respect to 
construction of the claims of its patents. Accordingly, Smith & Nephew reserves the 
right to supplement, amend, or otherwise modify its invalidity contentions as the case 
proceeds, and particularly after ArthroCare provides its proposed claim construction 
and/or after the Court construes the claims of ArthroCare' s patents. 

Nevertheless, as of the present time, Smith & Nephew incorporates its previous 
responses by reference, and further responds as follows: 

Certain of Smith & Nephew's invalidity contentions arc based on invalidity under 
35 U.S.C. § 102 and/or § 103 in view of certain prior art references. In the interest of 
brevity and convenience, rather than repeat the full names of those references in 
connection with each such contention, Smith & Nephew will instead refer to those 
references by number, in accordance with the following table:

4. All Patents 

Smith & Nephew also contends that the asserted claims of the '536, '882 and 
'592 patents are also invalid under 35 U.S.C. § 102(f) and/or § 1 16 because of improper 
inventorship. 

Smith & Nephew's investigation into its defenses is continuing, and it reserves 
the right to assert additional invalidity defenses as discovery progresses.
