I. MOTION OFFENSE STANDS BY ITS FEBRUARY 6 SUPPLEMENTAL BRIEF

AND RESERVES RIGHT TO SEEK LEAVE TO REPLY TO DROPBOX 

Because Dropbox deviated from the briefing schedule ordered by the Court, and to avoid 

burdening the Court with redundant briefing, Motion Offense stands by its February 6, 2024 

supplemental brief but reserves the right to seek leave to file a sur-reply to address Dropbox’s

responsive briefing due today, February 20, 2024, (Dkt. 427). 

The Court ordered the parties to file “simultaneous briefs . . . on or before February 6, 

2024.” (Dkt. 427.) However, Dropbox filed its opening brief on January 30, 2024 without 

consulting Motion Offense. (Dkt. 428.) This resulted in asynchronous briefing with Motion 

Offense filing its supplemental brief on the February 6, 2024 deadline set by the Court. (Dkt. 429.) 

While Motion Offense had only one week, its February 6 brief responded to Dropbox’s January 

30 brief. To avoid burdening the Court with redundant arguments, Motion Offense stands by its 

prior brief, (Dkt. 429), but reserves the right to request leave to file a short sur-reply as warranted. 

II. CONCLUSION

For at least the reasons set forth in Motion Offense’s February 6, 2024 brief, (Dkt. 429), 

the Court lacks subject matter jurisdiction to enter judgment on Dropbox’s affirmative defenses of 

invalidity including priority for each of U.S. Patent Nos. 10,587,548 and 11,044,215.
