Opinion

STARK, U.S. District Judge:

*646Plaintiff Koninklijke KPN N.V. ("KPN") sued multiple defendants in numerous related actions for alleged infringement of KPN's U.S. Patent No. 6,212,662 ("'662 patent"). Pending before the Court is Defendants' motion under Federal Rule of Civil Procedure 12( c) for judgment on the pleadings that all the claims of the '662 patent are invalid under 35 U.S.C. § 101. (C.A. No. 17-28 D.I. 28)1 For the reasons below, the Court will grant Defendants' motion.

I. BACKGROUND

KPN asserts the '662 patent in a total of eleven cases against Defendants; in seven of those cases it is the only asserted patent, while in the remaining cases it is one of five patents-in-suit.2 (See D.I. 29 at 1) The '662 patent is entitled "Method and Devices for the Transmission of Data with Transmission Error Checking." (D.I. 29-1 Ex. A) As the title suggests, the '662 patent is related to the "detection of errors, in particular transmission errors, in data streams and/or data packets." '662 patent at Abstract; see also id. at 1: 10-11 ("The invention relates to a method for the transmission of data with transmission error checking.").

The patent explains that errors may occur when data is transmitted, for example, "through electromagnetic radiation, inadequacies in a storage medium (transmission in time), and errors in switching and transmission equipment." Id. at 1:31-34. The claimed invention allows for checking such errors by first generating supplementary data at the transmitting and receiving end of a transmission channel using a first and a second function, respectively. Id. at 1: 10-20. The supplementary data that is generated at each end is then compared to see if they correspond with each other. Id. If they do not, then a transmission error may have occurred and the relevant data can be re-transmitted, if necessary. Id. at 1:43-46.

The '662 patent also generally describes the principles of data transmission and error correction in the prior art. Id. at Fig. 1;3:32-56. According to the patent, the concept of generating supplementary data to check for errors in data during transmission was already known. Id. at 1 :21-22, 34-3 7. The patent provides examples of prior art methods for generating supplementary data like using parity bits and a cyclic redundancy code (CRC) generator. Id. at 1:37-46, 60-67.

However, as the patent explains, these prior art systems and methods were not completely effective because transmission errors were sometimes not detected. The patent provides two specific instances when this occurred. One, referred to as "systematic errors," is when the errors repeat themselves, and the other is when the data is altered, for example, compressed or encoded, during transmission. Id. at 1:47-2:15. According to the "object of the invention," the claimed method "allows data to be checked for errors in a better way, and thus considerably increases the probability of transmission errors being detected," is well-suited "for application to compressed data," and can be "applied in a simple manner." Id. at 2: 18-26.

*647To achieve this objective, the '662 patent, unlike the prior art methods, varies the original data to create supplementary data. See id. at 2:30-41. By varying the original data, the patent explains, the probability of detecting "systematic errors in particular increases considerably." Id. at 2:42-47.

The four claims of the '662 patent are reproduced below:

1. A device for producing error checking based on original data provided in blocks with each block having plural bits in a particular ordered sequence, comprising:
a generating device configured to generate check data; and
a varying device configured to vary original data prior to supplying said original data to the generating device as varied data;
wherein said varying device includes a permutating device configured to perform a permutation of bit position relative to said particular ordered sequence for at least some of the bits in each of said blocks making up said original data without reordering any blocks of original data.
2. The device according to claim 1, wherein the varying device is further configured to modify the permutation in time.
3. The device according to claim 2, wherein the varying is further configured to modify the permutation based on the original data.
4. The device according to claim 3, wherein the permutating device includes a table in which subsequent permutations are stored.
