Try looking at the past owner of the patent- LIEP ENERGY LTD.

Try looking at the prior joint collaboration- Lithium exploration and development are coming to Saskatchewan, thanks to a new joint lithium project undertaken by Prairie Lithium Corp. and LiEP Energy Ltd.The two companies started the Prairie-LiEP Critical Mineral (PLCM) joint venture, a two-stage pilot project that will produce lithium hydroxide from Saskatchewan oilfield brines. The first stage is expected to begin this July, based in Regina, and the second stage is planned for the second half of 2021, with field operations in an undisclosed area in southern Saskatchewan.

Nice try
