Cal. Inst. of Tech. v. Hughes Communs., Inc.

Representative Claim

Claim 1 of the ‘032 patent:

  1. A method comprising:

receiving a collection of message bits having a first sequence in a source data stream;

generating a sequence of parity bits, wherein each parity bit “xj” in the sequence is in accordance with the formula xj=xj-1+∑i=1λ⁢⁢v(j-1)⁢λ+i, where “xj−1” is the value of a parity bit “j−1,” and “⁢∑i=1a⁢v(j-1)⁢a+1⁢″ is the value of a sum of “a” randomly chosen irregular repeats of the message bits; and

making the sequence of parity bits available for transmission in a transmission data stream.

Posture:

Motion for summary judgment.

Abstract Idea: Yes

“[T]he Court finds that all the claims at issue are directed to abstract ideas. … The claims explicitly recite the fundamental concepts of encoding and decoding data.”

Something More: Yes

“The asserted claims contain meaningful limitations that represent sufficiently inventive concepts, such as the irregular repetition of bits and the use of linear transform operations. Although many of these limitations are mathematical algorithms, these algorithms are narrowly defined, and they are tied to a specific error correction process.”
