Long winded reply part deux:
I don’t see how IP law could prevent anyone from using a table. Our tables are a distillation of the formulas that produced the numbers we see printed. The formula or algorithim (or whatever it is) I believe could be patented, but I don’t think it is. Didn’t the US Navy pioneer the data and means to determine nitrogen saturation levels? Does that help? I think the answer you seekgrasshopper depends on exactly what you want to do with the table or formula. If you want to use a table to further your own venture you may need get some permission.
