Samsung has asked the Korean Intellectual Property Office (KIPO) to re-examine two U.S. patents that NeoLayer cited in patent infringement lawsuits mentioning the Galaxy S24. Samsung Display filed the re‑examination requests on August 25 and August 27.
The two patents are US Patent No. 8,698,712, which covers OLED pixel structure technology, and US Patent No. 8,093,592, which relates to thin‑film transistor (TFT) technology.
NeoLayer, a non‑practicing entity, used both patents among six asserted in its first patent infringement lawsuit against Samsung Electronics filed in the U.S. District Court for the Eastern District of Texas in December 2025. In that case NeoLayer alleged the Galaxy S24’s pixel structure infringes patent 8,698,712, asserting the display uses two light‑emitting devices, each with its own driving switch and an addressing switch.
In June, NeoLayer filed a second patent infringement lawsuit against Samsung Electronics, this time accusing Samsung of infringing three patents; the Galaxy S24 was again mentioned in that case.
Galaxy S24 patent challenge: what Samsung is seeking
Samsung’s re‑examination requests question the patents’ patentability — specifically their novelty and inventive step — signaling an effort to challenge the validity of the two patents rather than only contesting infringement. If KIPO’s re‑examination finds either patent does not meet those requirements, NeoLayer’s claims against Samsung could be weakened. The re‑examination process, however, does not terminate the ongoing patent lawsuit in the United States.
