Roku, Inc. v.Anonymous Media Research Holdings, LLC
Roku, Inc.'s IPR challenge against Anonymous Media Research Holdings, LLC was denied by the PTAB, failing to meet the threshold for institution in all challenges. The Board rejected Petitioner's arguments regarding 'content offset,' requiring it to be relative to a reference point within the content.
Roku, Inc. v.Anonymous Media Research Holdings, LLC
Roku's IPR against Anonymous Media Research Holdings was denied because the key prior art reference (Seet) lacked written description support for non-audio media, preventing it from qualifying as prior art to the challenged patent.
Roku, Inc. v.Anonymous Media Research Holdings, LLC
Roku, Inc.'s IPR challenging Anonymous Media Research Holdings' content identification patent was denied by the PTAB. The Board found that Petitioner failed to demonstrate a reasonable likelihood of prevailing on its obviousness assertions against multiple prior art references.
Roku, Inc. v.Anonymous Media Research Holdings, LLC
Roku, Inc.'s IPR challenge against Anonymous Media Research Holdings was denied by the PTAB after failing to meet institution standards on grounds of obviousness and novelty.

Roku, Inc. v.Anonymous Media Research Holdings, LLC
The PTAB denied Roku's request to institute IPR against the '848 patent, finding that Petitioner failed to establish a reasonable likelihood of prevailing. The denial hinged on the failure of the Petitioner to prove that key prior art (Seet) was entitled to its provisional filing date due to lack of written description support for non-audio media.
Roku, Inc. v.Anonymous Media Research Holdings, LLC
Roku, Inc.'s IPR challenge against Anonymous Media Research Holdings was denied by the PTAB. The Board found Petitioner failed to demonstrate a reasonable likelihood of prevailing on its obviousness claims under 35 U.S.C. § 103.
Cisco Systems, Inc. v.Scale Video Coding LLC
The PTAB denied Cisco Systems' IPR petition against Scale Video Coding LLC, finding the asserted claims were not reasonably likely to be unpatentable over prior art references. The decision focused on technical limitations regarding bandwidth identification in video routers.
r-pac International Corporation v.Adasa Inc
The PTAB denied R-pac International Corporation's IPR challenge against Adasa Inc.'s RFID patent, finding that the prior art presented was cumulative to references already before the Office. The denial was based on Petitioner failing to show material Examiner error under Section 325(d).
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
Micron Technology successfully petitioned to challenge key claims in a semiconductor memory patent held by Yangtze Memory Technologies, leading to institution at the PTAB. The Board focused on obviousness (103) over Nakajima, balancing technical merits with parallel litigation factors.
Micron Technology, Inc. et al. v.Yangtze Memory Technologies Company, Ltd.
Micron Technology's IPR challenge against Yangtze Memory Technologies regarding 3D memory structures was denied by the PTAB. The Board found that Micron failed to demonstrate a reasonable likelihood of success on its obviousness grounds over prior art combinations.
Yangtze Memory Technologies Company, Ltd. v.Micron Technology, Inc. et al.
Yangtze Memory Technologies Company successfully convinced the PTAB to institute proceedings against Micron Technology for patent infringement. The Board found that Petitioner showed a reasonable likelihood of prevailing on at least one claim, despite arguments regarding foreign state actor status and RPI issues.
YANGTZE MEMORY TECHNOLOGIES COMPANY, LTD. v.Micron Technology, Inc. et al.
Yangtze Memory Technologies (YMTC) successfully petitioned to challenge Micron Technology's patent, leading the Board to institute the IPR. The petitioner argued that prior art disclosed or suggested key elements of flash memory technology. This decision allows YMTC to proceed with challenging claims related to semiconductor device structures.
