In an effort to create greater predictability for patent litigation in the Northern District of Illinois, the District enacted Local Patent Rules ("LPR") effective as of October 1, 2009. This annotated version of the LPRs collects decisions interpreting and applying the Rules up through February 28, 2018. After reciting each rule, we provide citations to opinions that have applied the rule, along with a relevant quote from the opinion and an explanatory heading.

We hope the annotated LPRs are a valuable resource to the judges, parties, and attorneys involved in patent litigation in the Northern District of Illinois. Of course, the LPRs and these annotations should be read in conjunction with the Northern District of Illinois Local Rules as well as any applicable rules or standing orders particular to each judge.
