On April 13, 2018, the Company entered into a Purchase and Sale Agreement with André Buys, pursuant to which the Company agreed to purchase from Mr. Buys a portfolio of registered patents, provisional patents, and other intellectual property relating to air and/or gas fired long guns or pistols, including pump action launchers and munitions used with such pistols and long guns, including self-stabilizing shaped or “finned” rounds (see note 7(a)). As consideration for the portfolio, the Company paid Mr. Buys $100,000, and incurred $10,000 in legal costs to transfer these patents. This consideration of $110,000 has been capitalized. These patents have a maximum life of 20 years, expiring on various dates beginning in November 2033 to 2038, and are amortized straight-line commencing June 2018 over a period of 15 years. The Company amortized $1,833 during the three- month period ended August 31, 2018. As the full arrangement included an option for full acquisition of the rights, conditional upon certain future events taking place, the Company has recorded the minimum rights to a licence arrangement as patents. As at August 31, 2018, the amount recorded as Patents refer to the perpetual, irrevocable, exclusive and non-exclusive license to use technology with respect to the portfolio (Note 7).
