VANCOUVER and CALGARY — Northstar Clean Technologies Inc. announces that it has been issued a follow-on patent by the United States Patent and Trademark Office for the Company’s proprietary technology for reprocessing asphalt shingles.

The Patent is the first of three follow-on patents (in addition to the first initial patent, totaling four patents in aggregate) submitted by the Company following the issuance of the Company’s first front-end technology patent, previously announced by the Company on November 8, 2022. The first two steps of the Company’s four step processing technology have now been fully patented, with the third and fourth submitted and under patent-pending protection. The Patent is expected to remain in force until 2044. Further, the Company continues to progress the application for patent approval in Canada, previously announced by the Company on February 14, 2023, and its international Patent Cooperation Treaty application.

Mr. Aidan Mills, President & CEO and Director of Northstar, stated “This recent patent issuance continues to demonstrate our commitment to protecting the innovation of our proprietary clean technology portfolio and the significant commercial opportunity that it represents for our company, our stakeholders, and our partners. We are delighted to be issued our second patent from the USPTO for the second stage of our four-stage proprietary technology for reprocessing asphalt roofing shingles. We believe the approval of the Patent is a testament to the strength of our proprietary technology and helps protect the Company’s intellectual property. We also believe the Patent furthers Northstar’s mission to be the leader in the recovery and reprocessing of asphalt shingles in North America.”
