`Ryan, 
`
`  
`Monday works for the call. Just let us know your team’s availability that day.  
`
`  
`We received PayRange’s amended infringement contentions. However, we noticed the cover pleading still asserts claim 
`1 of the ‘772 patent. While we appreciate that claim 11 depends from claim 1, we understand that claim 1 has been 
`disclaimed and thus cannot be asserted. Can you please confirm that claim 1 was asserted in error and serve a corrected 
`cover pleading to reflect that PayRange only asserts claim 11 of the ‘772 patent.  
`
`  
`Thanks, 
`Mark

`
`Dear Counsel,  
`  
`I write to address three issues: 
`  
`
`1. Please be advised that PayRange filed the attached statutory disclaimer for claims 1‐6, 8‐10 and 12‐20 of the 
`‘772 patent.   PayRange intends to serve amended infringement contentions for the ‘772 patent, asserting only 
`claim 11.  We are aiming to provide those amended contentions this week if possible.  If you’d like additional 
`time for invalidity contentions for the ‘772 patent please let know.  Relatedly, we think it makes sense to file a 
`joint notice alerting the Court of this development, especially given the pending MTD. 
`  
`2. We’d like to speak with our about ESI discovery.  We think it makes sense for the parties to exchange ESI search 
`terms and custodians (for their own collection) by December 8 and that the opposing party propose additional 
`search terms and any additional proposed custodians by December 15.  Please let us know if this works for CSC? 
`  
`3. We noticed that your document production did not include source code for CSC Go or CSCPay Mobile.  We 
`would like to discuss the logistics for inspecting your code.  PayRange will make its source code available as well. 
`Please let us know if you’d like to discuss.  
`
`  
`Best regards, 
`
