Most-quoted passages
The sentences later courts lift from this opinion, ranked by how many decisions quote each — the parts of the opinion doing the work. These counts are smaller than the citation total above because most of the 57 citing decisions cite the case generally; a passage count includes only decisions quoting that exact language verbatim.
“[W]ithout additional limitations, a process that employs mathematical algorithms to manipulate existing information to generate additional information is not patent eligible.”
7 later decisions quote this exact passage · from the majority“[[Image here]] in which the first term on the right side is the "value of parity bit j-1” and the second term on the right side is the "value of a sum of 'a' randomly chosen irregular repeats of the message bits.” . Courts should not view software as abstract simply because it exists in an intangible form. It is as fruitless to say that a human could use pencil and paper to perform the same calculations as a computer, as it is to say that a human could use p,encil and paper to write down the chemical structure of a DNA strand. In either case, any effort on the part of a human will only be a symbolic representation. The effort will not produce the same effect as executing a computer program or isolating a DNA strand. . To understand this concept, imagine a check node has the value O. It is connected to three information bits, all with the value 1. It is connected to two parity bits, one with the value 1 and one with a value to be determined. Let us call the value of the undeter mined pdrity bit y. To solve for y, the encoder would use the following formula: 0=1 + 14-1 + 1 +y. Using mod-2 addition, the encoder would determine that the value of y is O. . The method claim at issue in Digitech recited: A method of generating a device profile that describes properties of a device in a digital image reproduction system for capturing, transforming or rendering an image, said method comprising: generating first data for describing a device dependent transformation of color information”
