Short Summary
OnePlus has filed an IPR petition challenging Pantech’s 10,863,573 patent covering dual‑connectivity data handling. The petition asserts obviousness over three prior‑art references and seeks institution and cancellation of claims 1‑5 and 8‑12.
Detailed Summary
In a petition for inter partes review (IPR2025‑00762), OnePlus Technology (Shenzhen) Co., Ltd. challenges U.S. Patent No. 10,863,573 owned by Pantech Corporation. The patent claims a method and apparatus for sequential forwarding of multi‑flow data in a dual‑connectivity wireless system. OnePlus argues that claims 1‑5 and 8‑12 are obvious over the Koskinen publication alone, over a combination of Koskinen and Sammour, and over a combination of Deenoo and Sammour, citing detailed mappings of each claim limitation to the prior art. The petition also contends that discretionary denial under §§325(d) and 314(a) is inappropriate, emphasizing the strength of the obviousness arguments and the lack of prior‑art consideration during prosecution. The Board is asked to institute the review and cancel the challenged claims.
