`
`Jason,
`
`To enter the building there is an intercom at the front of the building that will connect Dr. Ricketts to our
`reception. If there are any issues, please have Dr. Ricketts connect with our practice coordinator Tammy
`Miller at 209-221-5225. Please inform Dr. Ricketts that he will need to have his ID, and will only be
`allowed to have a bound notebook when reviewing the code and schematics.
`
`Please note that given the holidays, we will have limited staffing, and the office will only be open from
`9am – 5pm from December 26 to 29. For the benefit of our staff during this week, we would also
`appreciate it if Dr. Ricketts or someone on your team lets us know if Dr. Rickett’s plans change such that
`he will not be there at any period of time during the two week you have reserved.

`
`
`Jason,
`
`
`
`Following up on the below and our conversation last week. We are fine with keeping the
`opening of discovery per the current scheduling order despite our request to move the marking
`hearing. I would appreciate if this could be a joint request. If not, I will send the language
`below in red instead.
`
`
`
`DRAFT:
`
`
`
`Dear Law Clerks,
`
`
`
`Pursuant to the Court’s local rules, the Parties write to confirm the Markman date in the above
`reference case. The date in the scheduling order is January 10, 2024, currently. However, the
`parties (Realtek) respectfully request(s) the Court move the Markman date to the following
`week, January 16 -19th, to provide more time to prepare for the arguments after the holidays,
`as well as for Realtek’s client representative to participate in the hearing (who is located in
`Taiwan). (Plaintiff is unopposed to Realtek’s request.) Thank you for your time and
`consideration.

`As yall know, the Markman is currently set for January 10, 2024. Given this is right after the
`holidays, would yall be amenable to moving the date back one week to January 16th to give us
`a little more breathing room? We are happy to discuss further as well. If that works with yall,
`can we send a joint email to the court asking the Court to set the markman date on January
`16th (or as soon as it can that week)?
