Short Summary
Klein Tools has filed an IPR petition challenging all 23 claims of Milwaukee Electric Tool’s ’952 container‑assembly patent, arguing obviousness over multiple prior‑art references.
Detailed Summary
In Petition IPR2024‑01401, Klein Tools, Inc. seeks inter‑partes review of claims 1‑23 of U.S. Patent No. 11,794,952, which covers a stackable container assembly with a coupling mechanism. The petitioner asserts that the claims are unpatentable under 35 U.S.C. § 103, relying on a combination of prior‑art references—including Burchia, Metabowerke, Lafragette, Chen, Lin, and Bensman—that were not considered during prosecution. Detailed motivation‑to‑combine arguments and claim‑by‑claim analyses are presented, and the petition argues that discretionary factors under § 325(d) do not favor denial, urging the PTAB to institute the review.
