Intangible assets amortization expense was $1,084 and $2,103 for the three- and six-month periods ended September 24, 2021, respectively, and $671 and $1,384 for the three- and six-month periods ended September 25, 2020, respectively. The majority of the Company’s intangible assets are related to patents as noted above. The Company capitalizes external legal costs incurred in the defense of its patents when it believes that a significant, discernible increase in value will result from the defense and a successful outcome of the legal action is probable. When the Company capitalizes patent defense costs, it amortizes these costs over the remaining estimated useful life of the patent, which is generally 10 years. There were no significant costs capitalized during either of the first six months of fiscal years 2022 or 2021. As of September 24, 2021, annual amortization expense of intangible assets for the next five fiscal years is expected to be as follows:
Remainder of 2022 | $ | 2,326 |
2023 | 3,360 |
2024 | 3,241 |
2025 | 3,039 |
2026 | 2,823 |
Thereafter | 21,342 |
Total | $ | 36,131 |
