Birchtech Jumps 10%, Says Remaining Attempts to Challenge Patents Under IPR Petition Have Ended

By

Birchtech (BCHT.TO), up 10.4% on last look, Wednesday said that termination requests for all remaining inter-parties review (IPR) petitions filed against its core patents have been filed.

The remaining entities involved in IPR proceedings have resolved their disputes with Birchtech and are ending all previously filed third-party challenges to the validity of Birchtech's patented SEA mercury emissions removal technology, a statement added.

No other active IPR proceedings remain.

Birchtech's patented SEA sorbent technology captures mercury emissions from coal-fired power plant. Since filing its first patent infringement claim in 2019, the company has worked to protect its intellectual property portfolio, it said.

"Since 2019, our patent protection strategy has been strong, highly enforceable and validated at the federal level," said chief executive Richard MacPherson.

"With these final challenges now resolved, that chapter is fully closed. The same expertise and intellectual property discipline that protected our Clean Air business is now being applied to Water. We are rapidly entering the massive, North American water treatment market with disruptive technologies and early commercial traction, a stable revenue foundation from our air business and a bolstered balance sheet."

Birchtech shares were last seen up $0.27, to $2.86, on the Toronto Stock Exchange.

Tower Resources Starts Drilling at Rabbit North Following Logistical Delays

Tower Resources' (TWR.V) drilling program previously scheduled for late April to advance the company's "major" orogenic gold (Au) discovery on its Rabbit North property near Kamloops, British Columbia is now underway following logistical delays related to the unusually high level of exploration activity in the province, it said on Wednesday.About ten holes are planned, mainly to extend the Thunder gold zone southwest toward the Durand Creek Fault and partially close the untested gap between the Thunder North and Blue Sky zones. The first hole, No. 074 on the Thunder zone, has intersected at least two strongly deformed and pyritized intervals typical of both this zone and Thunder North, it said.A planned extension to Hole 073, which was started at Thunder North at the end of the December 2025 drilling program, has been deferred until a study of current access restrictions along a seasonal creek in this area has been completed. "Drilling closer to the creek should then be possible, allowing for shorter and better placed holes in the Company's next drilling program," it added.Shares of the company were last seen unchanged at $0.17 on the TSX Venture Exchange.
