CALGARY, Alberta, Aug. 14, 2017 (GLOBE NEWSWIRE) -- NXT Energy Solutions Inc. (“NXT Energy” or the “Company”) (TSX:SFD) (OTCQB:NSFDF), a company focused on providing exploration solutions of its proven and proprietary Stress Field Detection ("SFD®") method, is pleased to provide an update on the status of current patent applications:

NXT previously announced the receipt of the Russian Patent No. 2608632 in January 2017.  This was the first patent granted to NXT for its SFD® technology.

We were notified on August 11^th that the Japan Patent Office has issued an original Letters Patent for the Japanese patent application No. 6175131. 

The Company has also received a number of communications from its Patent Attorneys:

• On April 26, 2017, the Canadian Intellectual Property Office issued a Notice of Allowance for NXT’s patent application (Application No. 2,874,450). 
• On July 13, 2017, the United States Patent and Trademark Office issued the Notice of Allowance for NXT’s patent application (Application No. 2014/550,779). 
• On July 25^th, 2017, the Mexican Patent Office issued the Notice of Allowance for NXT’s patent application (Application No. MX/a/2014/014309).

These “Notice of Allowances” are the final step prior to issuance of the Patents and we therefore expect Patents to be issued by all the above countries in the near future.

A new US CIP (Continuation in Part) patent application regarding the recently developed next generation of SFD® sensor design was submitted on August 4, 2017.

George Liszicasz, NXT Energy’s President and CEO, stated that “the granting of these international patents further validates NXT’s technical capability to detect geophysical conditions conducive to fluid entrapment, which require the combined presence of trap, reservoir and seal. These geophysical conditions are considered critical in oil and gas exploration.  We are proud of the continued technical advancements and the subsequent increase in industry recognition.”

In addition to the aforementioned countries, NXT also has applications pending in other international jurisdictions such as Europe, China, Brazil and India.
