Unified Patents added a new PATROLL contest, with a $2,000 cash prize, seeking prior art on at least claim 1 of U.S. Patent 11,189,321, owned and asserted by L4T Innovations LLC, an NPE. The '321 patent describes an event marking device designed to facilitate the identification and retrieval of media related to notable events. By marking the time of such events, users can easily access relevant recordings without sifting through extensive footage. It has been asserted against Ecobee Technologies.

The contest will expire on June 4, 2025. 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.
