US Patent 6233595 (issued in 2001) Fast multiplication of floating point values and integer powers of two. It covers the very narrow >case of multiplying a floating point number by an integer which is a power of two. Floating point numbers are defined as ssssssssss * 2 ^eee if you multiply this by 4 for example the result will be ssssssssss * 2 ^(eee+2). The claims (all 16) are based >around the significant not being altered in the process and only integer math is needed on the exponent. The case of multiplying a float by 4.0 is not claimed although it has the same solution. Disregarding the prior art what kind of claimed value could be justified for this invention? How many hours (minutes) could someone spend inventing this? The claimed value wouldn't cover the cost of filing and even if it was filed you or anyone else could afford to buy full rights and recover some money by licensing or selling them again (which would effectively force the original holder to license or sell restricted rights for much less). -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
