Short Summary
The PTAB instituted an inter partes review of Samsung's challenge to claims 1‑8 of U.S. Patent 8,808,909 and granted Samsung’s motion to join the earlier IPR filed by LG Energy Solution, consolidating the disputes.
Detailed Summary
In Decision IPR2025-00356, the Patent Trial and Appeal Board granted Samsung Electronics’ petition to institute an inter partes review of claims 1‑8 of U.S. Patent 8,808,909, finding the petition substantively identical to the earlier LG Energy Solution petition (IPR2024-01006). The Board also approved Samsung’s unopposed motion for joinder, merging the two proceedings so that all further filings will occur in IPR2024-01006. The Patent Owner did not oppose the joinder, and the Board emphasized procedural efficiency and the lack of new grounds of unpatentability.
