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 8,559,970, owned and asserted by Nostromo Holdings LLC, an NPE. The '970 patent is generally directed to providing location-based information and notifications to a user's device, based on location, user preference settings, and conditions for triggering the information delivery. It is being asserted against ADT, Resideo, Ecobee, Walgreens, Starbucks, Sephora, Macy’s, and Fibar USA.

The contest will expire on July 31, 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. PATROLL researchers are required to use Pearl to initially generate claim charts, and then researchers must add relevant figures and highlighting before submitting each chart. Each PATROLL researcher can generate up to 30 invalidity claim charts per month using Pearl. These charts can be downloaded then submitted to PATROLL.
