Brazil and United States Approves Further Patents to Clean Seed Capital

Clean Seed Capital Group Ltd.

October 6, 2022 – TheNewswire - Vancouver, British Columbia - Clean Seed Capital Group Ltd. (“Clean Seed” or the “Company”) (TSXV:CSX) and (OTC:CLGPF) is pleased to announce it has received allowances for the grant of patents in each of Brazil and the United States. The Company has filed its application for grant and expects the patents to be issued in the coming months.


United States - Expansion of its Variable Rate Metering Patent

The Company’s Variable Rate Metering patent secures Clean Seed’s ability to micromanage precision seeding and planting operations of multiple product inputs on every square foot of a farmer’s field. The Company’s original variable ratio metering US patent was issued in February 2018 and the Company has two sets of divisional applications in the US to expand its patent claims, the first of which was granted in 2020. This new second divisional application has now been accepted for grant, further expanding the coverage of this patent.


Brazil - Flow Control Patent

Flow control is one of the core innovations in the Company’s on-demand air system for the SMART Seeder™ technology. The flow control patent dovetails the innovations and processes between the Company’s staged air transfer system and its variable ratio metering system. The on-demand air system is a key piece to the SMART Seeder™ technology portfolio and a cornerstone to the Variable Rate Metering technology in seeding and planting equipment. This flow control patent family was filed subsequently and therefore, strengthens our Variable Rate Metering patent family, which effectively extends the overall life of that patent portfolio. We expect to receive additional similar approvals from other countries applied to in the coming months.


Graeme Lempriere, Chairman & CEO states: “These recent approvals to our patent expansions is an ongoing testament to the uniqueness of our technology and is further evidence that Clean Seed is at the forefront of agricultural innovation. The SMART Seeder MAX™, a true variable rate input application technology, is well secured as it prepares to enter the US$25B planting and seeding segment.”
