Amortization expense amounted to $79,110 and $26,037 for the six months ended November 30, 2025 and November 30, 2024, respectively. Goodwill was $2,152,215 as of November 30, 2025 and May 31, 2025. Intellectual Property As of November 30, 2025, the Company held three active U.S. patents and one pending U.S. patent application relating to its core technologies. These patents expire at various times between 2035 and 2038. The Company also owns seven federally registered trademarks in the United States, which it considers to be of material importance to its business. All trademark registrations are currently in good standing and are renewed as required. The Company historically has not capitalized costs associated with internally developed patents or trademarks, as they did not meet the criteria for capitalization under U.S. GAAP. As such, no intangible assets related to intellectual property has been recorded on the accompanying consolidated balance sheets.
