This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 108,021 and was likely granted around 1870.
Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.
The digit sequence 108021 first appears in π at position 278,899 of the decimal expansion (the 278,899ordinal-suffix:th digit after the integer 3).
