NOTE 4 – INTANGIBLE ASSETS/PATENTS

We amortize capitalized patent costs for internally generated patents on a straight-line basis for 7 years, which represents the estimated useful lives of the patents. The seven-year estimated useful life for internally generated patents is based on our assessment of such factors as: the integrated nature of the portfolios being licensed, the overall makeup of the portfolio over time, and the length of license agreements for such patents. The estimated useful lives of acquired patents and patent rights, however, have been and will continue to be based on a separate analysis related to each acquisition and may differ from the estimated useful lives of internally generated patents. The average estimated useful life of acquired patents is 6.7 years. We assess the potential impairment to all capitalized net patent costs when events or changes in circumstances indicate that the carrying amount of our patent portfolio may not be recoverable.

Components of intangible assets are as follows:

During the years ended September 3, 2024, and 2023, the Company recorded amortization expenses related to patents of $0 and $0, respectively.

In September 2021, the Company through its 100% owned subsidiary, US Thin Film Corporation, acquired Cima Specialty Material Limited, a Cayman Island corporation who holds a significant group of invention and processing patents in making Nanoparticle conductive thin film material for various industrial and technology applications. The patent portfolio was purchased from Cima Nanotech Holding Limited, the parent company of Specialty Material, and was paid with 31 million shares of GSTX common stock for the purchase. Subsequently the management and the auditors evaluated this intangible asset by considering its useful life, future economic benefit, and amortization, decided a value of US$6.5 million entered the book and reported in the 10K filing 2021. The delayed commercialization process for the past year prompted the management to examine the short-term revenue generating prospect of this intangible assets and to consider and accept the recommendation of our auditors for a total impairment of the patents.
