MAPS Prostar Holdings Inc

ProStar Holdings Inc. ("ProStar®" or the “Company") (TSXV: MAPS) (OTCQX: MAPPF) (FSE: 5D00) a world leader in Precision Mapping Solutions®, is pleased to announce that Canadian Patent No. 3,114,919, prepared and prosecuted by Lewis Roca, has been granted to ProStar. The patent is directed to a mobile device designed to collect digital utility asset data, including location data, in a more timely and efficient manner which helps to prevent damages to utilities and the environment during critical infrastructure construction, repair, and groundbreaking activities.

"ProStar is a pioneer in identifying the precise location of installed utilities as well as the innovative distribution and display of digital utility location information," said Raymond R. Tabandeh, the Lewis Roca partner who prosecuted the patent. "This is ProStar's 9th issued and active Canadian patent and further adds to ProStar's extensive U.S. and Canadian patent portfolio," added Tabandeh.

The patent covers a portable electronic device for utility data collection. The portable device may be a mobile phone, a laptop computer, a locator, and a personal digital assistant (PDA) and includes an antenna; and a data collection device to detect a signal from an installed utility asset. A location-determining device is coupled to the data collection device for determining a location of the installed utility asset. The data collection device includes: a wireless transceiver for wirelessly communicating with a remote server computer; a memory including a starter grid map, a password, and a name of an operator of the portable electronic device; a processor coupled to the wireless transceiver and the location determining device for creating a data record for the installed utility asset, the data record including information about a type and location of the installed utility asset, and information about time and date of the collected data. The processor selects an area from the stored starter grid map; transmits the data record and the selected area to the remote server computer; receives a latest grid map from the remote server computer for the area selected the stored starter grid map; generates a map including a representation of the installed utility asset from the data record and the received latest grid map; and displays the location data of the installed utility asset on a moving map as the portable electronic device is being moved.

Optionally, the processor generates a warning signal based on the location data of the installed utility asset, a location and movement direction of the portable electronic device, and a distance of the portable electronic device to the installed utility asset. The data record further includes information about topography of the selected area, a manner of collecting the data, information about the topography integrated into a GIS data transaction.

ProStar's Chief Executive Officer and a coinventor of the issued patent, Page Tucker, stated, "It is another major milestone to have been issued another major Canadian patent. Not only does this issuance validate that we are the pioneer in developing precision mapping solutions, but this issuance also puts us in a strong position supported by an extensive IP portfolio to protect us on any patent infringements, especially in Canada."

The Company granted 300,000 stock options today to Pat Clawson, in conjunction with his appointment as a Director (see news release dated April 12, 2023). The Options were granted at an exercise price of $0.20 and are exercisable for a five-year term, expiring April 26, 2028.
