Unified Patents added a new PATROLL contest, with a $3,000 cash prize, seeking prior art on at least claim 1 of EP-2661133-B1, owned by Ueran Technology LLC, an NPE. The EP’133 patent details a radio communication system between a mobile station device and a base station. It introduces methods for the mobile device to transmit a random access preamble to the base station, receive a response with timing deviation information, and manage uplink sync status without relying on the timing deviation once sync is established.

The contest will expire on January 31, 2026. Please visit PATROLL for more information and to submit an entry for the contest. 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.
