Samsung Austin Semiconductor, LLC et al. v.Sung, Chien-Min
Samsung Austin Semiconductor challenges the validity of Sung's '270 Patent before the PTAB, asserting that claims related to CMP pad conditioning are obvious. The petition relies heavily on combinations of prior art references (Chou and Sung’479) to demonstrate non-obviousness under 35 U.S.C. § 103.
Samsung Austin Semiconductor, LLC et al. v.Sung, Chien-Min
Samsung Austin Semiconductor challenges the '802 Patent covering Chemical Mechanical Planarization (CMP) pad dressing technology. The Petitioner argues that prior art references, including Tsai et al., anticipate or render obvious all 21 claimed claims. This is a foundational challenge to the patent's validity in semiconductor manufacturing.
Samsung Austin Semiconductor, LLC et al. v.Sung, Chien-Min
Samsung Austin Semiconductor challenges the validity of Sung's patent (9138862) in a Petition, asserting that various prior art references anticipate or render obvious the claimed CMP pad dresser technology. The arguments center on how Sung’026 and combinations with other references teach all limitations of the claims regarding particle arrangement and cutting depths.
Samsung Austin Semiconductor, LLC et al. v.Sung, Chien-Min
The PTAB issued a Final Written Decision finding all eight challenged claims unpatentable based on obviousness. The Board accepted the Petitioner's argument that combining Chou and Sung ’479 provided sufficient motivation to achieve the claimed narrow variation in CMP technology.
Samsung Austin Semiconductor, LLC et al. v.Sung, Chien-Min
The PTAB found all 20 claims of U.S. Patent No. 9138862 unpatentable by anticipation or obviousness over Sung ’026. The technology relates to Chemical Mechanical Polishing (CMP) pad conditioning methods, and the Board concluded that Petitioner successfully established invalidity across all grounds presented.
Samsung Austin Semiconductor, LLC et al. v.Sung, Chien-Min
The PTAB issued a Final Written Decision finding that most claims (1-9 and 12-21) of the '802 patent were unpatentable over prior art references, primarily Tsai. The Board relied heavily on anticipation and obviousness grounds, while also addressing written description challenges to specific claim limitations.
Samsung Austin Semiconductor, LLC et al. v.Sung, Chien-Min
The PTAB granted institution for all 21 claims in this IPR, finding sufficient evidence of record that prior art (Tsai, Sung '026, Sung '146) anticipates or renders obvious the claimed technology. The decision was reached despite concerns regarding parallel district court litigation involving Samsung and other entities.
Samsung Austin Semiconductor, LLC et al. v.Sung, Chien-Min
The PTAB granted institution for the IPR against Samsung Austin Semiconductor, LLC et al., despite arguments from the patent owner that the disclosures were too general or lacked specific enablement. The Board found sufficient evidence to support anticipation and obviousness claims based on prior art Sung ’026.
Samsung Austin Semiconductor, LLC et al. v.Sung, Chien-Min
The PTAB has instituted an IPR challenge against Samsung's 8974270, finding a reasonable likelihood of success on obviousness grounds. The Board accepted Petitioner's arguments that combining prior art references renders multiple claims unpatentable.
Samsung Electronics Co., Ltd. et al. v.Harbor Island Dynamic, LLC
The PTAB found all twenty challenged claims unpatentable in this IPR proceeding concerning backside metal adhesion. The Board adopted the Patent Owner's position that the claim language does not require strict direct contact for 'on a bottom surface.'
Samsung Electronics Co., Ltd. et al. v.Harbor Island Dynamic, LLC
Samsung successfully petitioned to institute IPR against Harbor Island Dynamic's patent 9147609. The Board found a reasonable likelihood of success based on technical arguments showing prior art (Cooney) discloses the claimed tapered hollow center in semiconductor vias.
YANGTZE MEMORY TECHNOLOGIES COMPANY, LTD. v.Micron Technology, Inc. et al.
The PTAB denied institution of an IPR challenge against Micron by Yangtze Memory Technologies because the Petitioner failed to satisfy its statutory duty to identify all Real Parties in Interest (RPIs).
