Source Review

Identified USPTO change targets:
  • MPEP section: 719.05 – Add new subsection II.C, Office Provided Artificial Intelligence Based Search Tools.
  • MPEP section: 902.03(e) – Revise PE2E SEARCH discussion to describe Similarity Search, mandatory use during plant and utility examination, and file-wrapper recordation.
  • MPEP section: 904.02(b) – Revise first paragraph to state that Similarity Search use is mandatory and cross-reference MPEP 719.05 and 902.03(e).

Notes

Source review: the USPTO memorandum expressly identifies affected MPEP sections and states that its guidance supersedes the current MPEP until the MPEP is updated.

This BlueIron page records the pending USPTO update and cross-references affected BlueIron MPEP, U.S.C., and C.F.R. pages. Official MPEP text remains unchanged until USPTO incorporates the update.
