Realtime Data LLC v. Synacor Inc.

United States District Court, E.D. Texas, Tyler Division

April 25, 2018

REALTIME DATA LLC, Plaintiff,
v.
SYNACOR INC., Defendant.

          MEMORANDUM OPINION AND ORDER

          JOHN D LOVE UNITED STATES MAGISTRATE JUDGE.

         This claim construction opinion construes the disputed claim terms in U.S. Patent Nos. 9, 054, 728 (the '728 Patent); 7, 415, 530 (the '530 Patent) and 9, 116, 908 (the '908 Patent). Plaintiff Realtime Data LLC (“Realtime” or “Plaintiff”) alleges that Defendant Synacor Inc. (“Synacor” or “Defendant”) infringes the '728 Patent, the '530 Patent, and the '908 Patent. Plaintiff filed an opening claim construction brief (Doc. No. 46), to which Defendant filed a responsive brief (Doc. No. 48), and Plaintiff filed a reply (Doc. No. 52).[1] The parties additionally submitted their Updated Joint Claim Construction Chart pursuant to P.R. 4-5(d). (Doc. No. 55.) On April 5, 2018, the Court held a claim construction hearing. Upon consideration of the parties' arguments, and for the reasons stated herein, the Court adopts the constructions set forth below.

         OVERVIEW OF THE PATENTS

         Plaintiff alleges Defendant infringes certain asserted claims of the '728 Patent, the '530 Patent, and the '908 Patent. Plaintiff states that the '728 Patent involves “content compression.” (Doc. No. 46 at 2.) Plaintiff alleges that the “patent[] [is] directed to systems and methods of digital-data compression utilizing different techniques based on the specific content of the data.” Id. Plaintiff maintains that the patent utilizes data within a data block and identifies one or more parameters of the content of that data. Id.

         The '728 Patent is entitled “Data Compression Systems and Methods.” The '728 Patent claim 1 is representative of the claims set forth:

1. A system for compressing data comprising;
a processor;
one or more content dependent data compression encoders; and
a single data compression encoder;
wherein the processor is configured:
to analyze data within a data block to identify one or more parameters or attributes of the data wherein the analyzing of the data within the data block to identify the one or more parameters or attributes of the data excludes analyzing based solely on a descriptor that is indicative of the one or more parameters or attributes of the data within the data block;
to perform content dependent data compression with the one or more content dependent data compression encoders if the one or more parameters or attributes of the data are identified; and
to perform data compression with the single data compression encoder, if the one or more parameters or attributes of the data are not identified.

         The '530 and '908 Patents are related and share substantially similar specifications. The patents are entitled “System and Methods for Accelerated Data Storage and Retrieval” and are described by Plaintiff as a “data acceleration” family. (Doc. No. 46 at 3.) These claims address problems with modern disk storage limited by physical media restrictions by “utiliz[ing] a plurality of different compression techniques and, optionally, a post-compression descriptor, which would indicate the compression algorithm that was used on a particular data block.” Id. at 4 (citing '530 Patent at 12:38-40). Claim 1 of the '908 Patent is representative of the claims set forth:

         1. A system comprising:

a memory device; and
a data accelerator configured to compress: (i) a first data block with a first compression technique to provide a first compressed data block; and (ii) a second data block with a second compression technique, different from the first compression technique, to provide a second compressed data block;
wherein the compressed first and second data blocks are stored on the memory device, and the compression and storage occurs faster than the first and second data blocks are able to be ...
