James Donald Peterson
How Judge Peterson decides
Patterns drawn from this judge's own signed orders. Every observation links to the order it came from.
What persuades
His patent-litigation background shows in disciplined claim construction: he applies the Phillips hierarchy and grants summary judgment of non-infringement where the accused device lacks the asserted claim limitations, resolving the parties' cross-motions limitation by limitation.
“DZEM’s motion for partial summary judgment, Dkt. 98, is GRANTED in part and DENIED in part: a. The DZEM sensor does not infringe claims 1, 2, 4, 7, and 8 of the ’153 patent. b. The DZEM sensor does not infringe claims 9–13 and 18 of the ’038 patent.”
Procedural preferences
At summary judgment he holds the non-movant to a 'put up or shut up' standard: speculation, unsworn filings, and argument in briefs do not create a triable issue, but where the record contains genuinely disputed facts (foreseeability, comparative negligence, excessive force) he denies the motion and sends them to the jury.
“IT IS ORDERED that Prime Communications’ motion for summary judgment, Dkt. 24, is DENIED.”
He resolves motions to dismiss claim by claim, granting in part and dismissing some claims with prejudice while letting others proceed, and dismisses improperly named parties (such as the State) from the case.
“The defendants’ motions to dismiss, Dkt. 65 and Dkt. 67, are GRANTED in part and DENIED in part.”
