324 / 32914 years or less, 1625–1700
Key point
Of the 329 stated terms in 1625–1700, 324 are 14 years or less; 4 are still 21 years (1631, 1632, 1638, 1663).
- Definition
- Grants per year 1617–1700 whose first written term is 21 years, and whose first written term is 14 years or less.
- Formula
- counts per year
- How to read it
- After 1624 terms of 14 years or less become the rule, but a few 21-year terms remain.
- Caveats
- Section 6 of the Statute of Monopolies limited patents for new inventions to 14 years or less. The table only counts the terms written in the record. Where an entry states further terms (mines, Ireland, a later revenue; column term_other in the entry table, counted per year in this table), the first is counted.
