Detailed Summary

In a petition for inter partes review, BOE Technology Group Co., Ltd. challenges claims 1‑13 of U.S. Patent No. 8,391,020, which cover an electro‑optical device with specific LCD panel wiring arrangements for testing electrical connections. BOE contends that the claimed configurations were disclosed in the Takenaka (U.S. patent application 2008/0291379), Ito (Japanese publication 2009168877A), and Takemura (Japanese publication H0643473A) references well before the patent’s priority date, rendering the claims obvious under pre‑AIA 35 U.S.C. §103. The petition includes an expert declaration by Dr. Patrick Murphy and argues that the examiner’s failure to cite these references during prosecution warrants cancellation of the entire claim set.
