AFFIRMATIVE DEFENSES FIRST AFFIRMATIVE DEFENSE (Lack of Personal Jurisdiction) Counts I-V 1. This Court lacks personal jurisdiction over Comcast. SECOND AFFIRMATIVE DEFENSE (Improper Venue) Counts I-V 2. Venue is improper in this judicial district. THIRD AFFIRMATIVE DEFENSE (Failure to State a Claim) Counts I-V 3. 4. Counts I-V of the Complaint fail to state a claim upon which relief can be granted. Comcast has not infringed any claim of any of the '903, 159, '761, '234, '444

patents ("Rembrandt's asserted patents"). 5. Comcast has not caused, with knowledge, specific intent, or otherwise, equipment

suppliers, service providers, and/or others to infringe any claim of any of Rembrandt's asserted patents. 6. Rembrandt has not been damaged in any amount, manner, or at all by reason of

any act alleged against Comcast and therefore the relief prayed for cannot be granted. 7. Rembrandt is not entitled to permanent injunctive relief. FOURTH AFFIRMATIVE DEFENSE (Invalidity) Counts I-V 8. On information and belief, Rembrandt's asserted patents are invalid at least for

failure to satisfy one or more of the conditions of Title 35 United States Code, including without limitation, Sections 101, 102, 103, and 112 thereof.

FIFTH AFFIRMATIVE DEFENSE (Misuse) Counts I-V 9. On information and belief, Rembrandt's asserted patents have been misused by

Rembrandt by the commencement and maintenance of this action, in bad faith, without probable cause in knowing, or when it should have known, that it had no valid claim of patent infringement against Comcast, and for Rembrandt's enforcement of said patents and demands for royalties and other damages with respect to products not covered by its patents. SIXTH AFFIRMATIVE DEFENSE (Laches) Counts I-V 10. 11. Rembrandt's claims are barred, in whole or in part, by the doctrine of laches. More specifically, and without limiting the generality of the foregoing paragraph,

Rembrandt has accused devices that practice one or more of the DOCSIS standards of infringing the patents-in-suit. 12. Comcast and/or its predecessors in interest have used products or services that

comply with one or more of the DOCSIS standards since no later than May of 1998. Rembrandt knew or reasonably should have known that Comcast and/or its predecessors in interest had used such products or services at that time and since. However, Rembrandt failed to assert its current claims that Comcast infringes the patents-in-suit until November of 2006. 13. Rembrandt's delay in filing suit is unreasonable and inexcusable, and has caused

Comcast material evidentiary and/or economic prejudice. Rembrandt's claims are accordingly barred by the doctrine of laches. COUNTERCLAIMS Defendant and Counterclaimant Comcast asserts the following counterclaims against
