Intangible assets amortization expense was $1,087 and $3,190 for the three- and nine-month periods ended December 24, 2021, respectively, and $926 and $2,310 for the three- and nine-month periods ended December 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 nine months of fiscal years 2022 or 2021.

As of December 24, 2021, annual amortization expense of intangible assets for the next five fiscal years is expected to be as follows:

Remainder of 2022	$	935
2023	3,612
2024	3,480
2025	3,260
2026	3,032
Thereafter	21,666
Total	$	35,985
