Claim 1 Application of U.S. Patent No. 6,508,678 to Charter Communications

[PRE] An electrical connector 

assembly, comprising:

Charter Communications (“Charter”) and purchasers/users of Charter devices make, use, offers to 

sell, sell, and/or import into the United States the claimed “electrical connector assembly.” As 

illustrated herein Charter devices that include one or more HDMI ports (e.g., receivers, DVRs) 

satisfy the claimed “electrical connector assembly.” 

Moreover, Charter instructs and encourages end users of Charter devices to make or use the claimed 

“electrical connector assembly” by advertising Charter devices support HDMI and providing 

instructional materials and user guides that instruct users to connect an HDMI cable to an HDMI 

port on a Charter device. By providing HDMI port(s) on Charter devices, Charter also contributes to 

the making or use of the claimed “electrical connector assembly.” Such ports are a material part of 

the claimed “electrical connector assembly” and are not suitable for noninfringing use.
