In 2021, we determined the fair value of the Devicix tradename was more likely than not at $0 based on management’s best estimate and recognized a $560 loss on abandonment of intangible assets. Intangible assets are amortized on a straight-line basis over their estimated useful lives. The weighted average remaining amortization period of our intangible assets is 1.9 years. Of the patents value at December 31, 2022, $95 are being amortized and $111 are in process and a patent has not yet been received. Amortization expense of finite life intangible assets was $150 and $176 for the years ended December 31, 2022 and 2021, respectively. Estimated future annual amortization expense (except projects in process) related to these assets is approximately as follows:
Year |  | Amount |
2023 |  | $ | 159 |
2024 |  |  | 87 |
2025 |  |  | 14 |
2026 |  |  | 14 |
2027 |  |  | 14 |
Thereafter |  |  | 23 |
Total |  | $ | 311 |
