Unified Patents added two new PATROLL contests, each with a $2,000 cash prize, seeking prior art on the list below. The patents are owned by the Electronics and Telecommunications Research Institute (ETRI) and asserted by Sol IP, LLC, an NPE. The patents relate to wireless data transmission in a multiple-input and multiple-output (MIMO)/WLAN systems. They have been asserted against AT&T, Sprint, Verizon, Qualcomm, Volkswagen, and others.
The contests will expire on October 18, 2026. Please visit PATROLL for more information and to submit an entry for these contests. PATROLL researchers are required to use Pearl to generate claim charts. Submitted invalidity charts must address every limitation of the challenged claim. This may require using more than one prior art reference. Each PATROLL researcher can generate up to 30 invalidity claim charts per month using Pearl. These charts can be downloaded then submitted to PATROLL.
