LEDUP MANUFACTURING GROUP LTD. v.Seasonal Specialties, LLC
LEDUP Manufacturing Group Ltd. filed an IPR petition challenging the validity of Seasonal Specialties' patent covering series LED circuits with bypass resistors. The petitioner argues that the claimed features are anticipated or obvious based on prior art disclosures in lighting technology.
LEDUP MANUFACTURING GROUP LTD. v.Seasonal Specialties, LLC
LEDUP Manufacturing Group Ltd. has filed a petition challenging Seasonal Specialties, LLC's patent (US 11096252) covering LED bypass circuits and series lighting technology. The petitioner asserts that claims 1-14 are unpatentable based on multiple grounds of anticipation and obviousness using various prior art references. This proceeding centers on whether the claimed circuit details were already known in the field.
Samsung Electronics America, Inc. et al. v.Collision Communications, Inc.
Petitioners challenge 18 claims of U.S. Patent No. 8089946, arguing they are obvious over prior art references like Walton and Learned. The central argument is that supporting legacy protocol modes in multi-user environments was a well-known concept in the field of wireless communications.
Samsung Electronics America, Inc. et al. v.Collision Communications, Inc.
Samsung petitions to invalidate Collision's '071 patent, arguing that its Multi-user Detection improvements are obvious under 35 U.S.C. § 103. Petitioners assert that prior art references (Jin, Baum, Tsai) combine known techniques in MIMO systems to render the claimed features non-inventive.
TCL Electronics Holdings Ltd. et al. v.Intellectual Ventures I LLC
TCL Electronics Holdings Ltd. has filed an Inter Partes Review petition challenging several claims related to Globally Asynchronous Locally Synchronous (GALS) clocking and Dynamic Voltage Scaling (DVS). The Petition asserts multiple grounds of obviousness, arguing that various combinations of prior art references render the claimed microprocessor architectures predictable.
Arista Networks, Inc. v.Orckit Corporation
Arista Networks challenges Orckit Corporation's patent (10652111) in an IPR, asserting that the claimed Deep Packet Inspection functionality within a Software Defined Networking controller is obvious.
Arista Networks, Inc. v.Orckit Corporation
Arista Networks has filed an IPR petition challenging Orckit Corporation's patent (8,830,821) on grounds of obviousness (§103). The challenge centers on the combination of Doshi’s MPLS path selection with reoptimization techniques from prior art like Guichard and Huang.
Arista Networks, Inc. v.Orckit Corporation
Arista Networks has filed a petition challenging U.S. Patent No. 7,545,740 held by Orckit Corporation, asserting obviousness under 35 U.S.C. § 103.

This challenge targets core networking technology used for load balancing.
LENOVO (UNITED STATES) INC. et al. v.Intellectual Ventures II
Lenovo has filed an IPR petition challenging Intellectual Ventures II's patent claims related to DDR SDRAM timing calibration and memory controllers. The petitioner argues that the claimed inventions are obvious under 35 U.S.C. § 103, relying on combinations of prior art references Johnson, Jeddeloh, and Keeth. This challenges the validity of a key patent in the semiconductor technology space.
LENOVO (UNITED STATES) INC. et al. v.Intellectual Ventures I LLC et al.
Lenovo challenged the validity of a University of Rochester patent related to multiple clock domain microprocessors. The petitioner argues that the claimed features are obvious over various combinations of prior art references, including Shenai and Georgiou.
LENOVO (UNITED STATES) INC. et al. v.Intellectual Ventures I LLC
Lenovo challenged claims related to cyclic advancement in OFDM systems, arguing that the claimed novelty is obvious under 35 U.S.C. § 103. The petitioner asserts that 'cyclic advancement' is merely a predictable equivalent of known techniques found in prior art references like Dammann and Hervin.
LEDUP MANUFACTURING GROUP LTD. v.Seasonal Specialties, LLC
The PTAB institution decision found sufficient evidence that the challenged claims are unpatentable, proceeding on grounds of anticipation (102) and obviousness (103). The case involves resistor bypass circuits for LED lighting, with the Petitioner arguing various prior art combinations teach the claimed invention.
LEDUP MANUFACTURING GROUP LTD. v.Seasonal Specialties, LLC
The PTAB institution decision found sufficient grounds for LEDUP MANUFACTURING GROUP LTD.'s challenge against Seasonal Specialties, LLC's patent (US 11096252).
